Troubleshooting
Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
Issue Possible Causes
Unit does not turn
on when pressing
ON/OFF button
The Unit has a 3-minute protection feature that prevents the unit from overloading.
The unit cannot be restarted within three minutes of being turned o.
The unit may change its setting to prevent frost from forming on the unit.
Once the temperature increases, the unit will start operating in the
previously selected mode again.
The set temperature has been reached, at which point the unit turns o the
compressor. The unit will continue operating when the temperature
fluctuates again.
The indoor unit
emits white mist
In humid regions, a large temperature dierence between the room’s air
and the conditioned air can cause white mist.
Both the indoor and
outdoor units emit
white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
Troubleshooting
The unit changes from
COOL mode to
FAN mode
The indoor unit makes
noises
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor unit
and outdoor unit make
noises
Low hissing sound during operation: This is normal and is caused by refrigerant
gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is
defrosting: This noise is normal and is caused by the refrigerant gas stopping or
changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.
SAFETY PRECAUTIONS
If any of the following conditions occurs, turn o your unit immediately!
• The power cord is damaged or abnormally warm
• You smell a burning odor
• The unit emits loud or abnormal sounds
• A power fuse blows or the circuit breaker frequently trips
• Water or other objects fall into or out of the unit

Preparations and Precautions
Air and foreign matter in the refrigerant circuit can
cause abnormal rises in pressure, which can damage
the air conditioner, reduce its efficiency, and cause
injury. Use a vacuum pump and manifold gauge to
evacuate the refrigerant circuit, removing any
non-condensable gas and moisture from the system.
Evacuation should be performed upon initial
installation and when unit is relocated.
BEFORE PERFORMING EVACUATION
Check to make sure the connective pipes
between the indoor and outdoor units
are connected properly .
Check to make sure all wiring is connected
properly.

7.
Wait for 5 minutes, then check that there
has been no change in system pressure.
8.
If there is a change in system pressure, refer
to Gas Leak Check section for information
on how to check for leaks. If there is no
change in system pressure, unscrew the cap
from the packed valve (high pressure valve).
9.
Insert hexagonal wrench into the packed valve
(high pressure valve) and open the valve by
turning the wrench in a 1/4 counterclockwise
turn. Listen for gas to exit the system, then
close the valve after 5 seconds.
10.
Watch the Pressure Gauge for one minute
to make sure that there is no change in
pressure. The Pressure Gauge should read
slightly higher than atmospheric pressure.

Using hexagonal wrench, fully open both the
high pressure and low pressure valves.
13.
Tighten valve caps on all three valves (service
port, high pressure, low pressure) by hand.
You may tighten it further using a torque
wrench if needed.
OPEN VALVE STEMS GENTLY
When opening valve stems, turn the hexagonal
wrench until it hits against the stopper. Do not
try to force the valve to open further.

Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
according to local regulations. For example, in North America, the standard pipe length is 7.5m (25’).
In other areas, the standard pipe length is 5m (16‘). The refrigerant should be charged from the service
port
on the outdoor unit’s low pressure valve.
The additional refrigerant to be charged can be
calculated using the following formula:
CAUTION
DO NOT mix refrigerant types.

Only for Australia models :
• This unit contains factory charged refrigerant covering 20m of refrigerant piping and additional
refrigerant charge on the installation site is not required for an installation with up to 20m
refrigerant piping. When refrigerant piping exceeds 20m, additionally charge an amount
calculated from the pipe length and the above table for the portion in excess of 20m.
• If an existing pipe system is used, a required refrigerant charge volume will vary depending on
the liquid pipe size.
Formula to calculate the volume of additional refrigerant required：
Additional charge volume (kg) = { Main length (m) – Factory charged volume 20(m) } × 0.03(kg/m)
• Make sure to remove the additional refrigerant amount according to the nameplate rated
charge (under 5m refrigerant piping ) under market or government verication testing .
