IMPORTANT - PLEASE READ THIS  
MANUAL BEFORE INSTALLING UNIT  
CAUTION  
Before installation, careful consideration must be given to  
how this system will operate if connected to any other piece  
of mechanical equipment, i.e. a forced air furnace or air  
handler, operating at a higher static. After installation, the  
compatibility of the two pieces of equipment must be  
confirmed by measuring the airflow’s of the Heat Recovery  
Ventilator (HRV) or Energy Recovery Ventilator (ERV) by  
using the balancing procedure found in this manual.  
For Models:

It is always important to assess how the operation of any  
HRV/ERV may interact with vented combustion equipment  
(ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).

NEVER install a ventilator in a situation where its normal  
operation, lack of operation or partial failure may result  
in the backdrafting or improper functioning of vented  
combustion equipment!!!

ERV Quest ions & Answers  
What is the difference between an HRV  
and damp situation. In fact, about 2/3 of the energy  
used by the air conditioner system is to remove  
moisture. Therefore, when ventilating in the summer,  
less moisture brought into the home means less work  
for the air conditioner, and energy savings for you.  
and an ERV?  
The core in an HRV (Heat Recovery Ventilator)  
transfers heat from one air stream to the other. This is  
called sensible heat. The term ERV (Energy Recovery  
Ventilator) is usually used to describe a unit with an  
enthalpic core that transfers moisture as well as heat  
from one air stream to the other. This (moisture  
transfer) is called latent heat.  
During the winter, an ERV recovers some humidity  
from the exhaust air, reducing the need for humidification  
,
if the required ventilation rate would make the home  
too dry.  
Enthalpic - what does it mean?  
Enthalpy is the term used to describe the energy  
content of air. This energy is a combination of the  
sensible and latent heat. Therefore, a core which  
transfers energy is called an enthalpic core.  
What's the difference between this type of  
core and a rotary type?  
Here's a list of characteristics of the fixed plate core.  
1. No rotating parts, so maintenance is easy and the  
unit lasts a long time.  
2. It is very flexible in terms of installation.  
3. The core can easily be changed.  
4. Because the supply and exhaust air streams are  
completely separate, there is very little cross  
leakage of any dust or germs.  
Is an ERV better than an HRV?  
NOT NECESSARILY!! In cold climates such as most  
of North America, an HRV works better than an ERV.  
This is because the air inside the home during the  
winter months will be more humid than the outside air.  
An ERV would transfer the latent heat (humidity) from  
the exhaust air back into the incoming airstream. This  
will aggravate moisture problems in the home and  
encourage the growth of mold and mildew. If the air in  
the home is too dry for comfort, an ERV will not help. A  
humidifier should be used to increase the humidity to  
a comfortable level.  
Can the core become clogged with dust?  
Because the surface of the core is a turbulent flow  
area, dust sticks to it easily; however, because the  
inside of the element is a laminar flow area, virtually no  
dust sticks to it.  
Where do you use an ERV instead  
of an HRV?  
An ERV is recommended for warm, humid areas with  
heavy air conditioning use. As there is no defrost in an  
ERV it is not recommended for areas where the  
temperature drops below -4˚C (25˚F).  
What is the maintenance?  
About once a year you should use a vacuum cleaner  
to remove the dust from the core's surface. DO NOT  
WASH WITH WATER!!  
Is an air filter needed?  
To prevent clogging of the core, an air filter should  
always be installed on the supply and exhaust sides of  
the core.  
Why transfer moisture in the summer  
(cooling season)?  
The enthalpic core will allow moisture to be transferred  
from a humid air flow to a dry air flow. This property is  
useful in the cooling season if an air conditioning  
system is used to lower the indoor humidity. You will  
then have dry, cool air in the exhaust of the ERV, and  
warm humid air in the supply stream. With these  
conditions, the ERV will be able to transfer the  
moisture and heat of the supply air to the exhaust air.  
In this way, the ERV will supply to the home air which  
is cooler and drier than outside. Remember that an  
ERV is not a dehumidifier, and on its own will not take  
moisture out of the air.  
How much ventilation do I need?  
During seasons when your windows and doors are  
closed, the ERV should operate continuously when  
the dwelling is occupied, and either continuously or  
intermittently when not occupied.  
For most installations the ERV will normally be set to  
operate continuously on low speed with the option of  
going to high speed as the need arises. For example;  
if you are entertaining and there is a large number of  
people present (some may be smoking), the unit  
should be switched to high speed.  
So why use an ERV?  
A properly operating air conditioner will not only lower  
the temperature in your house, but will also lower the  
humidity level. This prevents an uncomfortable cold  
Your ERV may be equipped with automatic or manual  
switches, but all ERVs will have a manual speed  
control override.

FUNCTION & CONTROL  
Operat ing t he Cont rolAir 15  
Self Test  
Each time the HRV/ERV is powered/energized the self  
test function will automatically initiate. During the self  
test the HRV/ERV will cycle through all the speeds  
available (1-5), test the damper motor operation and will  
default back to the previous mode/speed selection,  
(factory default is Speed 1). Total self test duration is  
approximately 1 min. 30 sec.  
Plugging in the HRV/ERV energizes the unit. A self test  
function will be performed every time the HRV/ERV is  
energized (refer to “Self Test” for more details). After  
the self test has completed successfully the HRV/ERV  
will default to Speed 1. This is the factory default  
setting. Follow the instructions found on the HRV/ERV  
door to select desired mode and speed, or refer to the  
instructions found on the following page.  
Aut omat ic Defrost Operat ion  
(Not on all models)  
Control Module  
The advanced technology of the digital microprocessor  
automatically activates the defrost system only as it is  
needed. To be an efficient heat recovery device, the  
HRV/ERV must effectively provide for core defrost as well  
as providing efficient heat exchange. As outdoor  
conditions cool, the temperature sensor (thermistor) tracks  
the supply air temperature. The thermistor then sends its  
signal to the microprocessor (circuit board) which initiates  
only the defrost cycle time required to clear the core. On  
recirculating defrost models, the core is defrosted when  
the supply air port is automatically blocked off and exhaust  
air is redirected back through the HRV/ERV. On damper  
defrost models, the core is defrosted when the supply air  
port is automatically blocked off and the warm air  
surrounding the HRV/ERV is drawn in through the defrost  
port. The mode indicator will flash RED during the defrost  
cycle. This dramatic advance makes more energy  
available for recovery as the unit spends less time in  
defrost mode. By optimizing the defrost cycle, the  
HRV/ERV combines money saving performance with a  
well designed and reliable control system.

DEFROST MODE - to ensure reliable operation during cold  
weather, the HRV/ERV will automatically cycle through its  
defrost mode as needed. (not on all models)  
The Control Pad can be removed and installed in a  
remote location (100’ wire length max). The Control Pad  
can be installed in a 2x4 box with a “Decora” type cover  
plate or can be installed in the optional “Ventilation  
Dehumidistat” or “Air Sentry”. When the Control Pad is  
installed in a remote location, all optional controls will still  
be wired to the Control Module on the HRV/ERV. When  
remotely mounted on its own, the Control Pad is wired to  
the Control Module by 3 wire (min. 20 gauge). Connect  
the colour coded terminals to the corresponding terminals  
on the Control Module. When the Control Pad is remotely  
mounted in the Ventilation Dehumidistat or Air Sentry,  
refer to optional controls page for wiring requirements.  
DEHUMIDISTAT - a control device that senses the amount of  
moisture in the air and will activate high speed fan operation  
when the air moisture level exceeds the control setting. The  
optimum air moisture level (or relative humidity [Rh]) in the  
typical home is in the range of 30 to 40% Rh.  
RESET - whenever resetting of the HRV/ERV is required,  
simply disconnect power for 30 seconds.  
STANDBY MODE - the HRV/ERV is energized and waiting for fan  
operation to be initiated by a remote device or manual override.  
THERMISTOR - the HRV/ERV's temperature sensor which  
measures electrical resistance in a known manner, as  
outdoor temperatures fluctuate.

USING THE DEHUMIDISTAT  
Some models have a built-in dehumidistat (an  
optional remote wall mount dehumidistat can be  
installed, see Optional Remote Controls), to  
control harmful, excess humidity during the  
heating season. The dehumidistat operates in  
% of RH (relative humidity) with 80 being high  
and 20 being low. The average person is  
comfortable between 30-45%.  
exceeds the set point on the control. Once the  
humidity in the house is reduced, the HRV/ERV  
will revert back to its previous setting.The  
dehumidistat should be set to off for all seasons  
except the heating season.  
Note: If your HRV/ERV is equipped with an internal  
and an external dehumidistat, the internal one can be  
turned off and not used.  
The dehumidistat will overide the ventilator to  
high speed when the moisture level in the home

95 MAX Port Specificat ions  
In order to make the 95 Max as space efficient as  
possible, the INDOOR supply and return ports are  
converted from round to oval shape. Overall size of the  
port remains the same. Simply bend a standard duct  
fitting to the correct shape, and attach to the oval port  
using the same method as for a round port.  
The 95 Max Heat Recovery Ventilator (HRV) has been  
designed to allow the installer to choose between two  
possible positions on the cabinet for the INDOOR  
EXHAUST (return from building) port. Illustrations in this  
manual show standard (side mounted) port location . The  
same specifications apply to both 95 Max setups,  
regardless of which port position is selected.

Variable Port Location  
Stale air enters the FRONT RIGHT side port. The air will  
pass down the front half of the core, then up the back half  
of the core and out the RIGHT REAR port.  
Variable Port Location / Installation (Model 95 Max only)  
The exhaust return port collar is not factory installed.  
Installer may choose either side mounted or alternate top  
mounted port by simply removing one of the two knock-out  
plates and attaching a port collar (supplied). To remove  
knock-out plate, insert a utility knife into the knock-out  
slits and trace them completely to puncture protective film  
underneath. Then, cut the solid tabs between the slits, using  
tin snips or side cutters, and remove the knock-out plate. If  
any protective film still blocks the opening, remove it now.  
Fresh outdoor air will enter the LEFT REAR port and  
pass down the back half of the core. It will then pass up  
the front half of the core, and out the LEFT FRONT port.  
This unique configuration allows the air to actually travel  
through the core twice, making the 95 MAX almost as  
efficient as a double core unit.

INSTALLATION  
Location  
The HRV/ERV must be located in a heated space where it will  
be possible to conveniently service the unit. Typically the  
HRV/ERV would be located in the mechanical room or an  
area close to the outside wall where the weatherhoods will be  
mounted. If a basement area is not convenient or does not  
exist, a utility or laundry room may be used  
Connecting Appliances to the HRV/ERV  
It is not recommended that any of the following appliances be  
connected to the HRV/ERV:  
• clothes dryer  
• range top  
• stovetop fan  
Attic installations are not normally recommended due to:  
A) the complexity of work to install  
• central vacuum system  
B) freezing conditions in the attic  
Lint, dust or grease will collect in the HRV/ERV, damaging  
the unit.  
C) difficulty of access for service and cleaning  
NOTE: Connecting any of these to the HRV/ERV will  
invalidate your warranty.  
Sufficient clearance at the front of the access door is required  
for servicing the air filters and core. A minimum of 25" (635  
mm) clearance is recommended so the door can be opened.  
Four PVC reinforced polyester hanging straps are provided  
for hanging the HRV/ERV from the basement floor joists.  
Installing the Drain Line and P-Trap (not on all models)  
When defrosting, the HRV/ERV may produce some  
condensation. This water should flow into a nearby drain, or  
be taken away by a condensate pump. The HRV/ERV and all  
condensate lines must be installed in a space where the  
temperature is maintained above the freezing point.  
Mounting  
The hanging straps should be attached to the unit at the top  
end corners (mounting screws are already located on the  
HRV/ERV case). Securely fasten the other end of the  
straps to the floor joists with wide head nails (not  
supplied), making sure the unit is level. The straps are  
designed to reduce the possibility of noise, resonance or  
harmonics; therefore using the full length of the strap between  
the HRV/ERV and the floor joists is recommended.  
At the bottom of the cabinet there are prepunched hole for the  
drain pan connectors (see below). Insert the drain spout  
through the hole in the drain pan. Do not forget the “O Ring”  
which seals the connector to the pan. REMEMBER TO HAND  
TIGHTEN ONLY the washer and lock nut which hold the drain  
connector in place.  
Electrical  
Construct a P-Trap using the plastic tee connector. Cut two  
The HRV/ERV should be plugged into a standard designated  
(120VAC) electrical outlet with ground. It is not recommended  
that an extension cord be used for this appliance. If further  
wiring is required, then a licensed electrician should make all  
electrical connections. It is recommended that a separate 15  
amp/120 volt circuit be used.  
the “T”  
lengths of hose and connect each piece to an end of  
fitting, then connect the other ends to the two drain  
spouts. Allow the "T" fitting to point upwards, and  
connect the drain line. Tape or fasten base to avoid  
any kinks. This creates a “trap” which will hold some  
condensate and prevent odours from being drawn up  
the hose and into the fresh air supply of the HRVERV  
.
WARNING:  
In order to prevent electric shock when cleaning or servicing  
the HRV/ERV, it is extremely important to confirm the  
polarity of the power line that is switched by the safety  
(disconnect) switch. The hot line (black) is the proper line to  
be switched. To confirm the proper polarity, use a voltmeter  
or test lamp to ensure there is no power after the switch  
when the door is open. Check between that point and ground  
(on the cabinet). This must be done as dwellings are  
occasionally wired improperly. Always make sure that the  
HRV/ERV is properly grounded.

INSTALLING AIR DUCTS  
To minimize air flow restriction, the flexible insulated duct that  
connects the two outside weatherhoods to the HRV/ERV  
should be stretched tightly and be as short as possible.  
A well designed and installed ducting system will allow the  
HRV/ERV to operate at its maximum efficiency.  
Always try to keep duct runs as short and straight as possible.  
See Installation Diagrams for various installation options.  
Twisting or folding the duct will severely restrict air flow. See  
below for the recommended connection of flexible insulated  
ducts to the the outside weatherhoods and the HRV/ERV.

Warmside Duct ing  
To maximize airflow in the ductwork system, all ducts should  
be kept short and have as few bends or elbows as possible.  
Forty-five degree elbows are preferred to 90° elbows. Use  
“Y” tees instead of 90° elbows whenever possible.

At least 6' (2 m) from the ventilation air intake  
At least 18" (457 mm) above ground or above the depth

All duct joints must be fastened with screws, rivets or duct  
sealant and wrapped with a quality duct tape to prevent  
leakage. We recommend aluminum foil duct tape.  
At least 3' (1 m) away from the corner of the building  
Not near a gas meter, electric meter or a walkway

Not into a garage, workshop or other unheated space  
Galvanized ducting from the HRV/ERV to the living areas  
in the house is recommended whenever possible, although  
flexible duct can be used in moderation if necessary.  
When installing the weatherhood, its outside perimeter  
must be sealed with exterior caulking.  
To avoid possible noise transfer through the ductwork  
system, a short length (approximately 12 " or 300 mm) of non-  
metallic flexible insulated duct should be connected between  
the HRV/ERV and the supply/ exhaust ductwork system.  
Installing the ducting from the  
weatherhoods to the HRV/ERV  
The inner and outer liners of the flexible insulated duct must  
be clamped to the sleeve of the weatherhoods (as close to  
the outside as possible) and the appropriate port on the  
HRV/ERV. It is very important that the fresh air intake line  
be given special attention to make sure it is well sealed. A  
good bead of high quality caulking (preferably acoustical  
sealant) will seal the inner flexible duct to both the  
HRV/ERV port and the weatherhood prior to clamping.  
The main supply and return lines to/from the HRV/ERV  
must be 6 inches (150 mm) minimum. Branch lines to the  
individual rooms may be as small as 4 inches (100 mm),  
but 5 inch (125 mm) lines are preferred .  
All ducts running through attics and unheated spaces must  
be sealed and insulated to code.

SUPPLY AIR DUCTING  
In homes without a forced air furnace, fresh air should be  
supplied to all bedrooms and living areas, excluding  
bathrooms, kitchen and utility areas. It should be supplied  
from high wall or ceiling locations. Grilles that diffuse the air  
comfortably such as the Techgrille™ are recommended.  
Dampers and Grilles  
The use of balancing dampers and/or adjustable grilles to  
balance the flow rates into various rooms is recommended.  
We suggest TECHGRILLE™ air diffusers.  
• The TECHGRILLE™ is available in 4", 5", 6" and 8" (100,  
125, 150 and 200 mm) sizes.  
If the floor is the only option available, then special care  
should be taken in locating grilles. Areas such as under  
baseboard heaters will help to temper the air. Also optional  
inline duct heaters are available for mounting in the supply  
duct work to add heat if required.  
• The TECHGRILLE™ is a round, fully adjustable grille,  
which provides superior, quiet air distribution.  
In homes with a forced air furnace, you may want to connect  
the HRV/ERV to the furnace ductwork (see information below).  
AIR FLOW  
SUPPLY  
Direct Connection to Furnace Ductwork  
Should you wish to hard duct the supply air directly into the  
cold air return of the furnace, remember to check the air  
flow balance of the HRV/ERV with the furnace fan both  
"ON" and "OFF" to determine that it does not imbalance the  
unit more than 10%. Also, it is advisable to include a short  
length of fabric flex duct or other non-metallic connector in  
this hard ducted line in order to keep the HRV/ERV  
separately grounded (electrically) from the furnace. This will  
avoid a possible shock hazard to service people if a short to  
ground develops in one of the devices.  
AIR FLOW  
EXHAUST  
Indirect Connect ion t o Ductwork  
If permitted by local codes, an indirect connection may be  
made between the HRV/ERV supply duct and the furnace  
return plenum. The fresh air from the unit may be directed  
at a grille installed in the cold air return duct of the furnace.  
The fresh air supply outlet from the unit should be no closer  
than 4 inches (100 mm) and no more than 12 inches (300  
mm) from the grille.  
Techgrille Air Diffusers  
We recommend the use of high mounted wall returns with  
grilles. The exhaust air duct from the kitchen should never be  
connected to a range hood. Instead, the exhaust grille  
should be mounted high on the wall at least 4 feet (1.2 m)  
horizontally away from the stove. A "flip-up", 6" X 10" (150 X  
250 mm) rectangular kitchen grille with removable grease  
filter is available (Part No. 10-002).  
St ale Air Exhaust Syst em  
The stale air exhaust system is used to draw air from the  
points in the house where the worst air quality problems  
occur. It is recommended that return air ducts are installed  
in the bathroom, kitchen, and laundry room. Additional  
return air ducts from strategic locations (i.e. greenhouse,  
atrium, swimming pool, sauna, etc.) may be installed. Also,  
the furnace return duct may be used to exhaust from. In this  
method, the exhaust air is not ducted back to the HRV/ERV  
with "dedicated lines" from bathrooms, kitchens, etc.  
Instead, the exhaust air is drawn out of the cold air return of  
the forced air furnace. This method has become popular  
and provides good ventilation when installed in accordance  
with the instructions. The furnace blower must be running  
w hen the unit is operating for this system to  
be effective.  
Dampers should be located just prior to the HRV/ERV to  
balance the stale air exhausted out of the house with a fresh  
air supply entering the house.

Fully Dedicated System  
Please Note: It is the responsibility of the installer to ensure all ductwork is sized and  
installed as designed to ensure the system will perform as intended. All air movement  
devices have a performance curve. The amount of air (CFM) that an HRV/ERV will deliver is  
directly related to the total external static pressure (E.S.P.) of the system. Static pressure is  
a measure of resistance imposed on the blower by length of duct work/number of fittings  
used in duct work, duct heater etc.

PITOT TUBE AIR FLOW BALANCING  
It is necessary to have balanced air flows in an HRV/ERV. The volume  
of air brought in from the outside must equal the volume of air exhausted  
by the unit. If the air flows are not properly balanced, then;  
• The HRV/ERV may not operate at its maximum efficiency  
• A negative or positive air pressure may occur in the house  
• The unit may not defrost properly  
For general balancing it is sufficient to move the pitot tube around in  
the duct and take an average or typical reading. Repeat this procedure  
in the other (supply or return) duct. Determine which duct has the high-  
est airflow (highest reading on the gauge). Then damper that airflow  
back to match the lower reading from the other duct. The flows should  
now be balanced. Actual airflow can be determined from the gauge  
reading. The value read on the gauge is called the velocity pressure.  
The Pitot tube comes with a chart that will give the air flow velocity  
based on the velocity pressure indicated by the gauge. This velocity  
will be in either feet per minute or metres per second. To determine the  
actual airflow, the velocity is multiplied by the cross sectional area of the  
duct being measured.  
• Failure to balance HRV/ERV properly may void warranty  
Excessive positive pressure may drive moist indoor air into the external  
walls of the building where it may condense (in cold weather) and  
degrade structural components. May also cause key holes to freeze up.  
Excessive negative pressure may have several undesirable effects.  
In some geographic locations, soil gases such as methane and radon  
gas may be drawn into the home through basement/ground contact  
areas. Excessive negative pressure may also cause the backdrafting of  
vented combustion equipment.  
This is an example for determining the airflow in a 6" duct.  
The Pitot tube reading was 0.025 inches of water.  
From the chart, this is 640 feet per minute.  
The 6" duct has a cross sectional area of  
The airflow is then:

5. Air flows in branch lines to specific areas of the house should be  
adjusted first prior to balancing the unit. A smoke pencil used at the  
grilles is a good indicator of each branch line's relative air flow.  
6. After taking readings of both the stale air to the HRV/ERV duct and  
fresh air to the house duct, the duct with the lower CFM ([L/s]  
velocity) reading should be left alone, while the duct with the higher  
reading should be dampered back to match the lower reading.  
7. Return unit to appropriate fan speed for normal operation

The accuracy of the air flow reading will be affected by how close to  
any elbows or bends the readings are taken. Accuracy can be  
increased by taking an average of multiple readings as outlined in the  
literature supplied with the Pitot tube.  
BALANCING PROCEDURE  
Pitot tube and gauge  
The following is a method of field balancing an HRV/ERV using a Pitot tube,  
advantageous in situations when flow stations are not installed in the duct-  
work. Procedure should be performed with the HRV/ERV on high speed.  
DUCT  
AIR  
The first step is to operate all mechanical systems on high speed, which  
have an influence on the ventilation system, i.e. the HRV/ERV itself and  
the forced air furnace or air handler if applicable. This will provide the  
maximum pressure that the HRV/ERV will need to overcome, and allow  
for a more accurate balance of the unit.

Drill a small hole in the duct (about 3/16"), three feet downstream of  
any elbows or bends, and one foot upstream of any elbows or bends.  
These are recommended distances but  
the actual installation may limit the  
amount of straight duct.  
Place pitot tube a minimum of 18" from blower or elbows  
The Pitot tube should be connected to a  
magnehelic gauge or other manometer  
capable of reading from 0 to 0.25 in. (0-  
62 Pa) of water, preferably to 3 digits of  
resolution. The tube coming out of the  
top of the pitot is connected to the high  
pressure side of the gauge. The tube  
coming out of the side of the pitot is con-  
nected to the low pressure or reference  
side of the gauge.

BALANCING COLLAR INSTRUCTIONS  
Push and turn with slotted  
screwdriver. Damper  
automatically locks when  
pressure is released.  
When connecting ductwork  
to the collar, take note where  
screws are located. Screws  
should be located no further  
than 1/2” from outside edge  
of collar, so as not to impede  
operation of the damper.  
Hard/Rigid

Technical Bullet in  
When using the ControlAir 15 relay contacts to initiate blower operation on a  
furnace, certain thermostats will initiate the outdoor cooling condenser when  
R and G are closed.  
Use this wiring configuration to stop the ControlAir15 relay contacts from initializing  
the condenser unit. This problem can occur at the thermostat because the Y terminal  
is connected to the G terminal internal to the stat. When R and G are closed at the fur-  
nace (by dehumidistat or relay) 24 Volts is sent to G at thermostat. 24 Volts is then  
sent through Y which will initiate outdoor condenser.
