Fixing and Piping
• Piping must be performed by qualied personnel
according to good refrigeration systems practices.
• Piping materials and insulation materials must be of
refrigerant quality.
• Select the pipe diameters according to the size of unit
and cut the pipe to design length by using pipe cutter.
• Install the are nuts and are the end of the pipes.
• Check that no foreign bodies are inside the piping.
• Align the central of the connecting pipes and tighten
the are nut.
•
Fix piping with pipe clamps and check that any pipe
vibrations cannot be transmitted to the building structure.
NOTES
• Connect the pipe correctly.
• Do not apply the excessive torque.
• Use an appropriate bending tool to form curves and
avoid over-tightening the refrigerant tubes.
• To prevent heat loss, the two lines must be insulated
separately.
Maximum Piping Length
The suction line must have a 2% gradient up to the
compressor on horizontal sections.
Where piping lengths are unusually long and include a
large number of oil traps, it may be necessary to adjust
to compressor charge.
Refrigerant piping connections
(FLARE connections)
To avoid alteration of unit capacities, check that piping
lengths and changes in elevation are kept to a strict
minimum.
Before connecting the refrigerant lines, follow the
procedures below (if pre-charged connection lines are
not supplied):
• Select copper pipe diameters according to the size of
unit to be installed.
• Install the refrigeration lines, checking that no foreign
bodies get inside the piping.
• Install the are connectors and are the ends of the
pipes.
•
Evacuate the piping. This operation, which should last
at least 15 minutes if there are large piping lengths and
changes in elevation, should be followed by a leak test.
Refrigerant charge to be added per extra meter
of piping length when more than 7 meters.
Note: Where the dierence in elevation between the indoor
unit and the outdoor unit is greater than 5 meters, install
an oil trap every 5 meters.

• Outdoor heat pump unit : install the unit at least 10 cm above ground level to facilitate drainage of defrost water and
prevent accumulation of ice. In effect, defrost water can cause accumulation of ice under the unit during subfreezing
outdoor temperatures.
• In areas with heavy snowfall it is best to install the unit on wall supports.
• In some regions, it is necessary to heat the bottom of the condensate drainage pan and the condensate drainage piping
to avoid ice formation, and resulting ice build-up in the fan compartment (heater strip must be at least 25 W/m).

• Moisture in the refrigerant circuit may freeze and block capillary tubing.
• Water may lead to corrosion of parts in the refrigeration system.
Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove
any noncondensables and moisture from the system.
Air purging with vacuum pump
Preparation
Check that each tube (both liquid and gas side tubes) between the indoor and outdoor units have been properly
connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and
the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are
kept closed at this stage.
•When relocate the unit to another place, perform evacuation using vacuum pump.
•Make sure the refrigerant added into the air conditioner is liquid form in any case.

out from the filter holder, then pull it downwards.
3. Remove the AIR FILTER from the indoor unit.
• Clean the AIR FILTER once two weeks.
• Clean the AIR FILTER with a vacuum cleaner or water, then dry it up
in cool place.
4. Remove the air freshening filter from its support frame (The installation
and removing method of the air freshening filter is different depending on
the models, see the pictures marked 1and 2on the left).
• Clean the air freshening filter at least once a month, and replace it
every 4-5 months.
• Clean it with vacuum cleaner, then dry it in cool place.
5. Install the AIR FILTER back into position.
6. Insert the upper portion of the AIR FILTER back into the unit taking care that
the left and right edges line up correctly and place filter into position.
nMaintenance
If you plan to idle the unit for a long time, perform the following:
(1) Operate the fan for about half a day to dry the inside of the unit.
(2) Stop the air conditioner and disconnect power.
Remove the batteries from the remote controller.
(3) The outdoor unit requires periodic maintenance and cleaning. Do not
attempt to do this yourself.
Contact your dealer or servicer.
nChecks before operation
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after the air conditioner has not
been used for a long time.
It is necessary to stop the air conditioner and disconnect the power supply
before cleaning.
WARNING
nCleaning the indoor unit and remote controller
• Use a dry cloth to wipe the indoor unit and remote controller.
• A cloth dampened with cold water may be used on the indoor unit if it
is very dirty.
•
The front panel of the indoor unit can be removed and cleaned with water.
Then wipe it with a dry cloth.

OPERATION TIPS
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
• The compressor cannot restart for 3 minutes after it stops.
Anti-cold air (Cooling and heating models only)
•
The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following
three situations and the set temperature has not been reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
• The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
• Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is
high resulting in lower heating efficiency of the air conditioner.
• During this condition air conditioner will stop heating operation and start defrosting automatically.
• The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost
buildup on the outdoor unit.
2. A white mist coming out from the indoor unit.
• A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL mode
in an indoor environment that has a high relative humidity.
• A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts
in HEAT mode operation after defrosting.
3. Low noise of the air conditioner.
• You may hear a low hissing sound when the compressor is running or has just stopped running.
This sound is the sound of the refrigerant flowing or coming to a stop.
• You can also hear a low “squeak” sound when the compressor is running or has just stopped running. This is
caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
• A noise may be heard due to louver restoring to its original position when power is first turned on.
4. Dust in blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit.
5. A peculiar smell come out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke.
6.
The air conditioner turns to FAN only mode from COOL or HEAT (for cooling and heating models only) mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically,
and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises
on COOL mode or falls on HEAT mode (For cooling and heating models only) to the set point.
7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative humidity
higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.
8. Heating mode (for cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation.
When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time,
heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a
comfortable temperature cannot be achieved by the air conditioner, we suggest you use a supplementary heating
device.
9. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit starts
flashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit with Auto-restart
feature, when the power restores, the unit restarts automatically with all the previous settings preserved by the memory
function.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote
controller to restart operation.
