If the compressor is operated when the service valve is open without connecting the pipe, it could cause explosion and injuries due
to abnormal high pressure in the system.
●
Stop the compressor before removing the pipe after shutting the service valve on pump down work.
If the pipe is removed when the compressor is in operation with the service valve open, air would be mixed in the refrigeration circuit
and it could cause explosion and injuries due to abnormal high pressure in the cooling cycle.
●
Only use prescribed optional parts. The installation must be carried out by the qualified installer.
If you install the system by yourself, it can cause serious trouble such as water leaks, electric shocks, fire.
●
Do not repair by yourself. And consult with the dealer about repair.
Improper repair may cause water leakage, electric shock or fire.
●
Consult the dealer or a specialist about removal of the air conditioner.
Improper installation may cause water leakage, electric shock or fire.
●
Turn off the power source during servicing or inspection work.
If the power is supplied during servicing or inspection work, it could cause electric shock and injury by the operating fan.
●
Do not run the unit when the panel or protection guard are taken off.
Touching the rotating equipment, hot surface, or high voltage section could cause an injury to be caught in the machine, to get
burned, or electric shock.
●
Shut off the power before electrical wiring work.
It could cause electric shock, unit failure and improper running.
●
Perform earth wiring surely.
Do not connect the earth wiring to the gas pipe, water pipe, lightning rod and telephone earth wiring. Improper earth could
cause unit failure, electric shock and fire due to a short circuit.
●
Earth leakage breaker must be installed.
If the earth leakage breaker is not installed, it can cause fire and electric shocks.
●
Use the circuit breaker of correct capacity. Circuit breaker should be the one that disconnect all
poles under over current.
Using the incorrect one could cause the system failure and fire.
●
Do not use any materials other than a fuse of correct capacity where a fuse should be used.
Connecting the circuit by wire or copper wire could cause unit failure and fire.
●

Be sure to perform air tightness test by pressurizing with nitrogen gas after completed refrigerant piping work.
If the density of refrigerant exceeds the limit in the event of refrigerant leakage in the small room, lack of oxygen can
occur, which can cause serious accidents.
●
For drain pipe installation, be sure to make descending slope of greater than 1/100, not to make traps,
and not to make air-bleeding.
Check if the drainage is correctly done during commissioning and ensure the space for inspection and maintenance.
●
Ensure the insulation on the pipes for refrigeration circuit so as not to condense water.
Incomplete insulation could cause condensation and it would wet ceiling, floor, and any other valuables.
●
Do not install the outdoor unit where is likely to be a nest for insects and small animals.
Insects and small animals could come into the electronic components and cause breakdown and fire. Instruct the user to
keep the surroundings clean.
●
Pay extra attention, carrying the unit by hand.
Carry the unit with 2 people if it is heavier than 20kg. Do not use the plastic straps but the grabbing place, moving the unit
by hand. Use protective gloves in order to avoid injury by the aluminum fin.
●
Make sure to dispose of the packaging material.
Leaving the materials may cause injury as metals like nail and woods are used in the package.
●
Do not operate the system without the air filter.
It may cause the breakdown of the system due to clogging of the heat exchanger.
●
Do not touch any button with wet hands.
It could cause electric shock.
●
Do not touch the refrigerant piping with bare hands when in operation.
The pipe during operation would become very hot or cold according to the operating condition, and it could cause a burn or frostbite.
●
Do not clean up the air conditioner with water.
It could cause electric shock.
●
Do not turn off the power source immediately after stopping the operation.
Be sure to wait for more than 5 minutes. Otherwise it could cause water leakage or breakdown.
●
Do not control the operation with the circuit breaker.
It could cause fire or water leakage. In addition, the fan may start operation unexpectedly and it may cause injury.
Always do it according to the instruction.
· Places where cosmetics or special sprays are
frequently used.
· Highly salted area such as beach.
· Heavy snow area
· Places where the system is affected by
smoke from a chimney.

① Before installation ③ Preparation before installation
④ Installation of indoor unit
② Selection of installation location for the indoor unit
ATTENTION
Select the suitable areas to install the unit under approval of the user.
Areas where the indoor unit can deliver hot and cold wind sufficiently. Suggest to the user
to use a circulator if the ceiling height is over 3m to avoid warm air being accumulated on
the ceiling.
Areas where there is enough space to install and service.
Areas where it can be drained properly. Areas where drain pipe descending slope can be
taken.
Areas where there is no obstruction of airflow on both air return grille and air supply port.
Areas where fire alarm will not be accidentally activated by the air-conditioner.
Areas where the supply air does not short-circuit.
Areas where it is not influenced by draft air.
Areas not exposed to direct sunlight.
Areas where dew point is lower than around 23°C and relative humidity is lower than 80%.
This indoor unit is tested under the condition of JIS (Japan Industrial Standard) high humid-
ity condition and confirmed there is no problem. However, there is some risk of condensa-
tion drop if the air-conditioner is operated under the severer condition than mentioned
above.
Areas where TV and radio stays away more than 1m. (It could cause jamming and noise.)
Areas where any items which will be damaged by getting wet are not placed such as food,
table wares, server, or medical equipment under the unit.
Areas where there is no influence by the heat which cookware generates.
Areas where not exposed to oil mist, powder and/or steam directly such as above fryer.
Areas where lighting device such as fluorescent light or incandescent light doesn’t affect the
operation.
Check if the place where the air-conditioner is installed can hold the weight of the unit. If it is
not able to hold, reinforce the structure with boards and beams strong enough to hold it. If the
strength is not enough, it could cause injury due to unit falling.
