Refrigerant Piping
Drill Hole in Wall
If indoor unit refrigerant piping is going to exit from the rear:
1. It is recommended that the refrigerant pipe flare connectors extend through the wall
to the outside. In some situations field-fabricated piping extensions will be required to
extend the indoor unit refrigerant flare connections to the outside of the wall.
2. Use mounting bracket diagrams and dimensions to find and mark the proper location
for the wall hole.
If refrigerant piping is going through the right or left side of front panel
(not allowed on Crown models):
Carefully cut hole in the side of the front panel for piping to enter indoor unit as shown below.
Find and mark the proper location for the wall hole. Use table below to determine recommended
wall hole size for your unit size.
3.
Cut the wall hole with a 5° to 10°
downward slant to the outdoors.
4. Insert a wall sleeve into hole to prevent
damage to refrigerant pipes, insulation,
condensate drain hose and wiring.
5. Proper weather proofing of the wall surface and wall sleeve is essential to
assure a trouble-free installation. Apply sealant, caulking or equivalent weather
proofing material around the perimeter of the wall sleeve (interior & exterior) to
eliminate outdoor air and water leaks into the living space.

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 indoor unit when system is
running.
You hear a slight cracking sound
when the system stops or starts.
The system will not run.
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 remote is not turned on.
• Batteries in the remote controller are low.
• Remote controller is in sleep mode or timer mode.
• Otherwise, contact a qualified service professional for assistance.
The unit is not heating or cooling
adequately.
Water leakage from the
outdoor unit.
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.
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.
35
TROUBLESHOOTING
PROBLEM
Water leaking from the indoor
unit into the room.
Wireless remote controller
does not work.
The unit will not deliver air.
CAUSE/SOLUTION
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 possible reasons
Solution: Check the following:
• The remote controller was not matched to the indoor unit.
See matching instructions.
• The batteries might be low. Change the batteries.
• The remote controller must be within 25 ft. (7.5 m) with no obstructions
of the indoor unit. If remote controller needs to be replaced, contact a
qualified service professional for assistance. In the meantime, use the
Aux button to operate the system.
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.
Moisture or condensation
on the discharge air louvers
or outlet vents.
Mode Conflict (E7) is displayed.
Cause: It is normal for the system to develop condensation or moisture on the
discharge air louvers when cooling warm humid air for a long period of time.
Solution: The condensation or moisture will disappear as the system cools and
dehumidifies the room space.
Cause: When indoor units have different mode settings (for example, some set
to Cool, others set to Heat, Fan Only or Dry) it creates a Mode Conflict.
Solution: Be sure that all indoor units are set to the same mode (i.e., Cool, Heat,
Fan Only or Dry). Once this is done, the Mode Conflict status will disappear.
