DUCTWORK INSTALLATION
Bottom Return Air Installation (18,000 BtuH Only)
The 18,000 BtuH size duct can be converted from a rear to bottom side return. More noise is produced
with the bottom return air location than the rear return air, so it is suggested to provide a duct silencer
to minimize the noise. The default location of the return air connection is at the rear.
If the bottom return air connection is desired, switch the location of the rectangular flange and the
return air cover plate as shown below:
1. Connect return air duct (#3) to the return air inlet of the unit (#4) and the other end to a return
air register. Ensure return ductwork is properly supported with hangers.
2. Connect supply air duct (#5) to the supply air outlet of the unit (#4) and the other end to a
discharge air register. Ensure supply ductwork is properly supported with hangers.

Pipe Testing
Leak Test
Refrigerant lines should be pressurized prior to evacuating system to check for leaks.
1. Connect regulated nitrogen to manifold. Attach hose to service port.
2. Open manifold valve to add nitrogen to a pressure of 500 lbs.
3. Maintain applied pressure for 30 minutes, leak-test flare fittings with soap bubbles. If no leak is
detected, release nitrogen.
Use vacuum pump, rather than refrigerant, to discharge air when installing the unit.
CAUTION
29
Vacuum Procedure
Important: Use a quality Micron Gauge to measure and validate the proper system vacuum
level achieved. Do not rely on the scale of a“bourbon tube”type gauge set to validate the
depth and quality of the vacuum.
1. Remove the caps of the liquid valve, gas valve and service port.
2. Connect gauge manifold and micron gauge to the service ports provided at the liquid and
suction service valves.
3. Connect a vacuum pump to the manifold gauge.
4. Open the lower pressure side of the manifold valve assembly and start the vacuum pump.
The switch at the high pressure side of the manifold valve assembly should be kept closed,
or evacuation does not fail.
5. Operate vacuum pump until a vacuum of 500 microns or less is achieved. The evacuation
duration depends on the vacuum pump size and unit’s capacity, generally 20 minutes for
the 9,000 BtuH units, to 1 hour for a larger 36,000 BtuH unit.
6. Close the manifold valves and shut off the pump.
a. If vacuum holds below 700 microns for 15
minutes, the system can be considered dry
and leak free. Go to step 5.
b. If vacuum increases to 800 microns or greater,
this is an indication of moisture in system
or a leak exists. Identify leak and repair as
necessary, after which repeat steps 4 and 5.
If moisture is suspect, purge system use triple
evacuation method using dry nitrogen.
7. Confirm that manifold valves are closed and disconnect the vacuum pump.
8. Open the service valves to the fully ‘back-seat’ position to let the refrigerant flow to the
indoor unit and balance the pressure in system.
Note: Do not allow air to enter the connection pipe when removing the hose.
9. Replace service valve caps and tighten.

TROUBLESHOOTING
PROBLEM
System does not restart.
Indoor unit emits unpleasant odor
when started
You hear a“water flowing”sound.
A thin fog or vapor coming out
of the discharge register when
system is running.
You hear a slight cracking sound
when the system stops or starts.
The system will not run.
The unit is not heating or cooling
adequately.
CAUSE/SOLUTION
Cause: The system has a built-in three-minute delay to prevent short and/or rapid
cycling of the compressor.
Solution: Wait three minutes for the protection delay to expire.
Cause: Typically unpleasant odors are the result of mold or mildew forming on
the coil surfaces or the air filter.
Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist,
contact a qualified service professional to clean the coil surfaces.
Cause: It is normal for the system to make“water flowing”or “gurgling”sounds
from refrigerant pressures equalizing when the compressor starts and stops
Solution: The noises should discontinue as the refrigerant system equalizes after
two or three minutes.
Cause: It is normal for the system to emit a slight fog or water vapor when
cooling extremely humid warm air.
Solution: The fog or water vapor will disappear as the system cools and
dehumidifies the room space.
Cause: It is normal for the system to make “slight cracking” sounds from parts
expanding and contracting during system starts and stops.
Solution: The noises will discontinue as temperature equalizes after 2 or 3 minutes.
Cause: There are a number of situations that will prevent the system from running.
Solution: Check for the following:
• Circuit breaker is “tripped” or “turned off.”
• Power button of Wired Programmable Controller is not turned on.
• Wired Programmable Controller is in sleep mode or timer mode.
• Otherwise, contact a qualified service professional for assistance.
Cause: There are a number of reasons for inadequate cooling or heating.
Solution: Check the following:
• Remove obstructions blocking airflow into the room.
• Clean dirty or blocked air filter that is restricting airflow into the system.
• Seal around door or windows to prevent air infiltration into the room.
• Relocate or remove heat sources from the room.
TROUBLESHOOTING
PROBLEM
Water leakage from the
outdoor unit.
Water leaking from the indoor
unit into the room.
The unit will not deliver air.
CAUSE/SOLUTION
Cause: It is normal for the outdoor unit to generate condensate water in the
reverse cycle heating and defrost mode.
Solution: This is normal. No action is required.
Cause:
While it is normal for the system to generate condensate water in cooling
mode, it is designed to drain this water via a condensate drain system to a safe location.
Solution: If water is leaking into the room, it may indicate one of the following.
• The indoor unit is not level right to left. Level indoor unit.
• The condensate drain pipe is restricted or plugged. All restrictions must
be removed to allow continuous drainage by gravity.
• If problem persists, contact a qualified service professional for assistance.
Cause: There are a number of system functions that will prevent air flow.
Solution: Check for the following:
• In heating mode, the indoor fan may not start for three minutes if the
room temperature is very low. This is to prevent blowing cold air.
• In heat mode, if the outdoor temperature is low and humidity is high,
the system may need to defrost for up to 10 minutes before beginning
a heating cycle.
• In dry mode, the indoor fan may stop for up to three minutes during the
compressor off delay.
• Otherwise, you should contact a qualified service professional for assistance.
