CLEARANCES
DUCT WORK
These units are adaptable to downflow use as well as rear
supply and return air duct openings. To convert to downflow,
use the following steps:
All units require certain clearances for proper operation and
service. Refer to Figure 3 for the clearances required for
combustion, construction, servicing and proper unit opera-
tion.
1. Remove the duct covers found in the bottom return and
supply air duct openings. There are four (4) screws
securing each duct cover (save these screws to use
later).
2. Install the duct covers, removed in step one, to the rear
supply and return air duct openings. Secure with the four
(4) screws used in step one.
Do not permit overhanging structures or shrubs to
obstruct the condenser air discharge outlet.
3. Seal the duct covers with silicone caulking.
Downflow units must have an L-shaped supply duct without
any outlets or registers located directly below the supply out-
let of the unit.
4
Unitary Products Group
173858-YIM-A-0306
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.
Filters should be checked monthly especially since this unit
may be used for both heating and cooling.
CONDENSATE DRAIN
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 min-
imize the transmission of noise.
A condensate trap is required to be installed in the conden-
sate drain. The plumbing must conform to local codes. Use a
sealing compound on male pipe threads. Install the conden-
sate drain line (3/4“ NPTF) to spill into an open drain.
SERVICE ACCESS
Access to all serviceable components is provided by the fol-
lowing removable panels:
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.

NOTE: Be sure to note supply and return openings.
Refer to Figure 3 for location of these access panels and min-
imum clearance.
Refer to Figure 3 for information concerning rear and bottom
supply and return air duct openings.
THERMOSTAT
FILTERS
The room thermostat should be located on an inside wall
approximately 56" above the floor where it will not be subject
to drafts, sun exposure or heat from electrical fixtures or
appliances. 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.
A filter rack and filters are standard on all units.
Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by
the blower, decreasing your units efficiency and increasing
operating costs and wear-and-tear on the unit and controls.

To check the supply air CFM after the initial balancing has
been completed:
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.
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
reinstall the two ¼ inch plugs removed in Step 1.
3. Using an inclined manometer, determine the pressure
drop across the evaporator coil.

The pressure drop through the economizer is greater than 100% outdoor air than for 100% return air. If the resistance of
the return air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

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 ener-
gize 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.
NORMAL MAINTENANCE
Prior to any of the following maintenance proce-
dures, shut off all power to the unit, to avoid per-
sonal injury.
2. On a call for cooling, the thermostat will send 24 volts to
“Y” on the fan control board. The 24 volt signal will ener-
gize contactor “M1", and power will be supplied to the
compressor and outdoor fan motor. If the fan switch on
the thermostat is on the ”AUTO" position, the thermostat
will also send a 24 volt signal to “G” on the fan control
board and the indoor blower will operate as indicated in
step 1.
Periodic maintenance consists of changing or cleaning filters
and general cleaning of the outdoor coil.
FILTERS - Inspect once a month. Replace Disposable or
clean Permanent Type as necessary. DO NOT replace Per-
manent Type with Disposable.
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” position, the 24 volt “G” signal will be
MOTORS - Indoor and outdoor fan motors are permanently
lubricated and require no maintenance.
OUTDOOR COIL - Dirt should not be allowed to accumulate
on the outdoor coil surface or other parts in the air circuit.
Cleaning should be as often as necessary to keep the coil
clean. Use a brush, vacuum cleaner attachment, or other
suitable means. If water is used to clean the coil, be sure that
the power to the unit is shut off prior to cleaning.
removed, and after a 60 second delay, the “K1" relay will
open and de-energize the indoor blower motor.
