174065-YIM-A-0206  
CLEARANCES  
FILTERS  
All units require certain clearances for proper operation and  
service. Refer to Figure 3 for the clearances required for com-  
bustion, construction, servicing and proper unit operation.  
Single phase units are shipped without a filter and is the responsi-  
bility of the installer to secure a filter in the return air ductwork or  
install a Filter/Frame Kit (1FF0114).  
WARNING:Do not permit overhanging structures or shrubs to  
obstruct the condenser air discharge outlet.  
A filter rack and a filters are standard on three phase units.  
Filters must always be used and must be kept clean. When fil-  
ters become dirt laden, insufficient air will be delivered by the  
blower, decreasing your units efficiency and increasing operat-  
ing costs and wear-and-tear on the unit and controls.  
DUCT WORK  
These units are adaptable to downflow use as well as rear sup-  
ply and return air duct openings. To convert to downflow, use  
the following steps:  
Filters should be checked monthly especially since this unit  
may be used for both heating and cooling.  
1. Remove the duct covers found in the bottom return and  
supply air duct openings. There are four (4) screws secur-  
ing each duct cover (save these screws to use later).  
CONDENSATE DRAIN  
2. Install the duct covers, removed in step one, to the rear sup-  
ply and return air duct openings. Secure with the four (4)  
screws used in step one.  
A condensate trap is required to be installed in the condensate  
drain. The plumbing must conform to local codes. Use a seal-  
ing compound on male pipe threads. Install the condensate  
3. Seal the duct covers with silicone caulking.

drain line ( “ NPTF) to spill into an open drain.  
4
Downflow units must have an L-shaped supply duct without  
any outlets or registers located directly below the supply outlet  
of the unit.  
SERVICE ACCESS  
Access to all serviceable components is provided by the follow-  
ing removable panels:  
Duct work should be designed and sized according to the  
methods of the Air Conditioning Contractors of America  
(ACCA), as set forth in their Manual D.  
Blower service access  
Electrical/filter access  
Compressor service access  
A closed return duct system shall be used. This shall not pre-  
clude use of economizers or ventilation air intake. Flexible  
joints may be used in the supply and return duct work to mini-  
mize the transmission of noise.  
Refer to Figure 3 for location of these access panels and mini-  
mum clearance.  
THERMOSTAT  
CAUTION: When fastening duct work to the side duct flanges on  
the unit, insert the screws through the duct flanges only.  
DO NOT insert the screws through the casing. Outdoor  
duct work must be insulated and waterproofed.  
The room thermostat should be located on an inside wall ap-  
proximately 56" above the floor where it will not be subject to  
drafts, sun exposure or heat from electrical fixtures or appli-  
ances. Follow manufacturer's instructions enclosed with the  
thermostat for general installation procedure. Four or five color  
coded insulated wires (minimum #18 AWG) should be used to  
connect thermostat to unit. See Figure 2.  
NOTE: Be sure to note supply and return openings.  
Refer to Figure 3 for information concerning rear and bottom  
supply and return air duct openings.

Checking Supply Air CFM  
a dry coil, the compressors should be deactivated while the test  
is being run.  
To check the supply air CFM after the initial balancing has been  
completed:  
4.Knowing the pressure drop across a dry coil, the actual CFM  
through the unit can be determined from the curve in Coil Delta  
P vs. Supply Air CFM figure.  
1.Remove the two ¼ inch dot plugs in the duct panel.  
2.Insert at least 8 inches of ¼ inch tubing into each of these  
holes for sufficient penetration into the airflow on both sides of  
the indoor coil.  
WARNING! Failure to properly adjust the total system air quan-  
tity can result in extensive system damage.  
After readings have been obtained, remove the tubes and rein-  
stall the two ¼ inch plugs removed in Step 1.  
3.Using an inclined manometer, determine the pressure drop  
across the dry evaporator coil. Since the moisture on an evapo-  
rator coil may vary greatly, measuring the pressure drop across  
a wet coil under field conditions would be inaccurate. To ensure  
NOTE: De-energize the compressors before taking any test  
measurements to ensure a dry indoor coil.

SEQUENCE OF OPERATION  
Heating  
Cooling  
The following sequences of operation are based on using a  
standard single-stage cooling thermostat.  
WITH POWER TO UNIT AND THERMOSTAT IN HEATING  
MODE.  
WITH POWER TO UNIT AND THERMOSTAT IN COOLING  
MODE.  
1. If the fan switch on the thermostat is in the “ON” position,  
the 24 volts at “G” will energize the “K1" relay contacts, and  
energize the indoor blower motor. If the fan switch on the  
thermostat is in the ”AUTO" position, the blower will oper-  
ate only when there is a call for heating by the thermostat.  
1. If the fan switch on the thermostat is in the “ON” position,  
the 24 volts at “G” will energize the “K1" relay on the fan  
control board, close the ”K1" relay contacts, and energize  
the indoor blower motor. If the fan switch is in the “AUTO”  
position, the blower will operate only when there is a call for  
cooling by the thermostat.  
2. On a call for heating, the thermostat will send 24 volts to  
“W1" on the fan control board. The 24 volts signal will ener-  
gize relay ”K2" on the fan control board, and the first stage  
of electric heat will be energized.  
2. On a call for cooling, the thermostat will send 24 volts to “Y”  
on the fan control board. The 24 volt signal will energize  
contactor “M1", and power will be supplied to the compres-  
sor and outdoor fan motor. If the fan switch on the thermo-  
stat is on the ”AUTO" position, the thermostat will also send  
a 24 volt signal to “G” on the fan control board and the in-  
door blower will operate as indicated in step 1.  
3. When the heating demand is satisfied, the electric heat will  
be de-energized when the 24 volt “W1" and ”W2" signals  
are removed. If the fan switch on the thermostat is in the  
“ON” position, the indoor blower will continue to run. If the  
fan switch is in the “AUTO” position, the “K1" relay will open  
and de-energize the indoor blower motor after the appropri-  
ate time delay.  
3. When the demand for cooling has been satisfied, the “M1"  
contactor will be de-energized when the 24 volt ”Y" signal is  
removed. If the fan switch on the thermostat is energized  
when the 24 volt “Y” signal is removed. If the fan switch on  
the thermostat is in the “ON” position, the indoor blower will  
continue to run. If the fan switch is in the “AUTO” posi-  
tion, the 24 volt “G” signal will be removed, and after a  
60 second delay, the “K1" relay will open and de-  
energize the indoor blower motor,
