WARNING
1
Safety precautions
·Perform grounding
Does not connect the earth wire to a gas pipe, water pipe, lightning rod or telephone earth wire.
Defective grounding could cause an electric shock.
·Do not install the unit in a place where an inflammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.
·Fasten a flare nut with a torque wrench as specified in this manual.
When fastened too tight, a flare nut may break after a long period and cause a leakage of refrigerant.
·Install an earth leakage breaker depending on the installation place(where it is humid).
If an earth leakage breaker is not installed, it could cause an electric shock.
·Perform the drainage/piping work securely according to the installation manual.
·If there is a defect in the drainage/piping work, water could drop from the unit and household goods
could be wet and damaged.
CAUTION
2
·Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner.
·This appliance is not intended for use by persons (including children) with reduced physical, sensory

qualified persons in order to avoid a hazard.
·The appliance shall be installed in accordance with national wiring regulations.
·Servicing shall only be performed as recommended by the equipment manufacturer.
·The method of connection of the appliance to the electrical supply and interconnection of separate
components is detailed in below part. The wiring diagram with a clear indication of the connections
and wiring to external control devices and supply cord is detailed in below part.
·In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance must not

Installation instructions
Put Cloth or Paper
Transport the product as close to the installation location as
practical before unpacking.
·Handling Method
When hanging the unit, ensure a balance of the unit, check
safety and lift up smoothly.
(1) Do not remove any packing materials.
(2) Hang the unit under packing condition with two ropes,
as shown in Fig below.
·Handling
If have no package to move, Please protect with cloth
or paper.
CAUTION：
Before choosing the installation site, obtain user approval.
·Where it is not exposed to strong wind.
·Where airflow is good and clean.
·Where it is not exposed to rain and direct sunshine.
·Where neighbors are not annoyed by operation sound or hot air.
·Where rigid wall or support is available to prevent the increase of operation sound or vibration.
·Where there is no risk of combustible gas leakage.
·Where it is at least 3m away from the antenna of TV set or radio. An amplifier may be required for the affected
device.
·Install the unit horizontally.
·Please install it in an area not affected by snowfall or blowing snow. In areas with heavy snow, please install a
canopy, a pedestal and/or some baffle boards.
Avoid the following places for installation where air conditioner trouble is liable to occur.
·Where there is much machine oil.
·Salty places such as seaside.
·Where sulfide gas is generated such as a hot spring.
·Where there is high-frequency or wireless equipment.
NOTE:
When operating the air conditioner in low outside temperature, be sure to follow the instruction describe below.
·Never install the outdoor unit in a place where its air inlet/outlet side may be exposed directly to wind.
·To prevent exposure to wind, install the outdoor unit with its air inlet side facing the wall.
·To prevent exposure to wind, it is recommended to install a baffle board on the air outlet side of the outdoor unit.

Drainage elbow and drain hose installation
Install Drainage Elbow and Drain Hose
·The condensate water may drains from the outdoor unit
when the unit operates in heating mode. In order to avoid
disturbing neighbors also to protect the environment, it is
necessary to install a drainage elbow and a drain hose to
drain out the condensate water.
·Please do the drainage work before the indoor unit and
outdoor unit are connected. Otherwise, it will be difficult
to install drainage elbow after the machine becomes
immovable.)
·Connect the drain hose (field-supplied, inside diameter:
15mm) as shown in the figure for drainage.

Drainage elbow
NOTE:
Do not use the drain elbow in the cold region. Drain
may freeze to stop the fan runs.

The maximum allowable length of refrigerant piping, and the maximum allowable height difference between the
outdoor and indoor units, are listed below. The shorter the refrigerant piping is, the better the performance will be.
So the connecting pipe should be as short as possible.
1. Piping requirement
2. Piping material
(1)Prepare the copper pipe on the spot.
(2) Choose dustless, non-humid, clean copper pipe. Before installing the pipe, use nitrogen or dry air to blow away
the dust and impurity on the tube.
Additional refrigerant charge
The unit has been filled with refrigerant, but if L (total pipe length) exceeds standard length, additional
refrigerant (R410A) change is required.
For 18K: Additional refrigerant charge=[L-50ft (15m)]×0.807oz/5ft (15g/m)
For 24K: Additional refrigerant charge=[L-75ft (22.5m)]×0.807oz/5ft (15g/m)
For 36K: Additional refrigerant charge=[L-98ft (30m)]×0.807oz/5ft (15g/m)
For 42K: Additional refrigerant charge=[L-125ft (37.5m)]×0.807oz/5ft (15g/m)

3. Processing of Refrigerant Piping
(1) Pipe cutting
·Cut the cooper pipe correctly with pipe cutter.
(2) Burrs removal
·Completely remove all burrs from the cut cross section of the pipe.
·Put the end of the copper pipe downward to prevent burrs from
dropping in the pipe.
(3) Putting nut on
·Remove flare nuts attached to indoor and outdoor units, then put them
on pipe having completed burr removal.
(Not possible to put them on after flaring work).
·Flare nut for pipe depending on the diameter of pipe.
(4) Flaring work
·Perform flaring work using flaring tool as shown below.
(5) Check
·Compare the flared work with the figure below.
·If flare is noted to be defective, cut off the flared section and perform flaring work again.
