Vert-I-Pak Installation Recommendations
For proper unit performance and maximum operating life please refer to the minimum installation clearances below.
Figure 1
VERT-I-PAK® units must be installed on an outside wall. Confined spaces and/or covered areas should be
avoided. Units should be installed no closer than 12" apart when two units are side by side. If three of more
units are to operate next to one another allow a minimum of 60" between units or pairs of units. Also, a vertical
clearance of 60" should be maintained between units. Units installed on the bottom floor should be mounted
at least 6" off of the ground.

5) Ductwork Preparation
6) Chassis Installation
1) Duct ESP:
Install the following components as shown in Figure 5.
To determine your system's indoor external static pressure
(ESP, in inches of water) use a duct calculator (as provided
by your duct supplier). Include all flex duct transitions and
discharge grille(s). If flex duct is used, be sure all the slack
is pulled out of the flex duct. Flex duct ESP can increase
considerably when not fully extended. DO NOT EXCEED a
total of .30 ESP, as this is the MAXIMUM design limit for the
VERT-I-PAK A-Series unit.
A. Ensure that the wall plenum is installed in accordance with
the VPAWP1-8/1-14 Installation Manual.
B. Place the chassis into the closet with the outdoor side
facing the wall plenum opening.
C. Slide the chassis into the wall plenum until the plenum
divider seal is established. (See Figure 9)

7) Chassis Final Connections
With the chassis in place, you are now ready to begin chassis
connections:
A. Move the thermostat switches to "OFF" and "AUTO." This
will keep the thermostat from cycling the chassis until final
connections are complete.
Electrical shock and moving parts hazard can cause injury
or death. If you have not done so, pull out the disconnect
head found on the front of chassis before continuing instal-
lation! Disconnect external power at the breaker.
B. Connect the ductwork onto the 10" collar. Plastic wireties (field
supplied) are suggested to secure the ductwork in place. Use
2 wire ties, one for each inner and outer flex duct sleeve.
C. Using the two 3/4" plugs supplied with the unit, plug two of
the condensate drain holes. Connect a drain to the third
condensate exit location. Be sure to use teflon tape or
approved pipe sealant on all drain connections and plugs.
(See Figure 10.)
D. For 208 Volt power only: you must move the transformer wire
as shown in Figure 7, Page 9.
E. Review the Final Installation Checklist on Page 12 before
replacing the power quick disconnect, reconnecting power
to the chassis, plugging in the remote thermostat harness, or
operating the chassis.

system. A secondary drain pan may be placed beneath the
chassis to prevent condensated spillage due to improper
installation or unit malfunction.
The chassis requires a simple single stage heat-cool wall thermostat.
Each chassis comes with a terminal strip located in the electrical
control box. All internal chassis wiring (low & high voltage) is factory
ready for 230 Volt operation. For 208 Volt operation a single wire
MUST BE CHANGED ON THE TRANSFORMER. Refer to Figure
7 on page 9.
IV. Service & Warranty
14) Servicing / Chassis Quick Changeouts
The chassis is designed for quick disconnect and change out. For
minor electrical service, the control box cover lifts straight up after
the screws & disconnect head are removed. For major electrical,
refrigeration and fan service the chassis must be removed from
utility closet.
10) Low Ambient Protection
Each chassis is equipped with Low Ambient Protection in the form of
a suction line thermostat. This thermostat will prevent compressor
operation at low suction line temperatures. Each chassis is also
equipped with a factory installed bellows that will drain water from
the base pan to prevent the fan slinger from freezing during winter
weather.
To Remove the Chassis from the Closet:
A Switch the wall thermostat off.
B Pull the power disconnect located in the front of the chassis.
11) Heating Defrost (Heat Pump Models Only)
C Turn off all power to the unit at the main breaker or
disconnect.
All Heat Pumps have a passive heating defrost system. Defrost
occurs as needed and automatically switches to electric heat during
defrost. When the outdoor ambient temperature drops below a 45°F
factory setting, the chassis automatically switches to electric heat.
As outdoor ambient temperatures rise above 45°F, the chassis
returns to the heat pump mode. The changeover temperature is user
adjustable from approximately 32°F - 55°F. The defrost thermostat
may also be used to lock out the compressor in an emergency
heat situation.
D Disconnect the thermostat wiring.
E Disconnect the electrical connection.
F Disconnect the ductwork.
G Disconnect the drain connection.
H Slide the chassis out of the wall plenum.
I Lift the chassis out of the utility closet.
12) Fresh Air Door
15) Warranty
The Fresh Air Door is an "intake" system. The fresh air door is
opened via a slide on the front of the chassis located just above
the indoor coil. Move the slide left to open and right to close the
fresh air door. The system is capable of up to 60 CFM of fresh air
@ ~.3" H20 internal static pressure.
All service work must be done by a qualified servicer. See
Warranty on the next page, and consult your dealer or contractor
for details.
13) Condensate Disposal System
The internal drain connections are 3/4" FPT fittings on the right, left
and outdoor side of the unit. See Figure 10 on page 12. The chassis
is designed with a condensate drain system that has 3 parts. The
three parts work as follows:
Electrical shock and moving parts hazard can cause injury
or death. Pull out the disconnect head found on the front
of the chassis before servicing.
Part 1: The system’s first stage increases energy efficiency
utilizing a factory installed fan that slings the cold
condensate onto the hot outdoor coil.
Part 2: When high outdoor humidity prevents the slinger from
disposing of all the condensate, the excess condensate
overflows into the internal drain connection.
Part 3: If Parts 1 & 2 fail for any reason, excess condensate
overflows from a spillway directly into the wall plenum
to the outside of the building. IF THIS OCCURS, THIS
IS YOUR WARNING THAT THE CHASSIS OR DRAIN
NEEDS SERVICING.
