WARNING
• To recover refrigerant, stop the compressor before closing the valve and disconnecting the refrigerant piping.
If the refrigerant piping is disconnected before the compressor stops and when the service valve is opened, it can cause
frostbite or injury due to rapid refrigerant leakage, and burst or personal injury due to anomalously high pressure in the
refrigerant circuit into which air is sucked
• Do not put the drainage pipe directly into drainage
channels where poisonous gases such as sulphide gas
can occur.
Poisonous gases will flow into the room through drainage
pipe and seriously affect the user’s health and safety.
• Never connect the power cord to the central socket.
Never use extended wires or share a socket with other
electrical appliances.
This may cause fire or electric shocks due to defective
contact, poor insulation and over-current etc.
• Do not discharge R410A to the atmosphere. R410A is a
fluoride greenhouse gas and can cause global warming
if it is discharged to the atmosphere.
• Ensure that no air enters in the refrigerant circuit
when the unit is installed and removed.
If air enters in the refrigerant circuit, the pressure in the
refrigerant circuit becomes too high, which can cause
burst and personal injury.
• Do not bundle or wind the power cord. Or, do not
deform the power plug by treading it.
This may cause electric shocks, heating or fire.
• Do not run the unit with removed panels or
protections.
Touching rotating equipments, hot surfaces or high
voltage parts can cause personal injury due to entrapment,
burn or electric shocks.
• Do not perform any change of protective device itself
or its setup condition.
The forced operation by short-circuiting protective device
of pressure switch and temperature controller or the use of
non specified component can cause fire or burst.
• Carry out the electrical work for ground lead with care.
Do not connect the ground lead to the gas line, liquid line, lightning conductor or telephone line’s ground lead. Incorrect
grounding can cause unit faults such as electric shocks due to short-circuiting. Never connect the ground lead to the gas
line as gas leakage can cause explosion or fire.
CAUTION
• Use the circuit breaker with correct breaking capacity
at all electrodes.
If a wrong breaker is used, it can cause the unit
malfunction and fire.
• Earth leakage breaker must be installed.
If the earth leakage breaker is not installed, it can cause
fire or electric shocks.
• Secure a space for installation, inspection and
maintenance specified in the manual.
Insufficient space can result in accident such as personal
injury due to falling from the installation place.
• After maintenance, all wiring, wiring ties and the like,
should be returned to their original state and wiring
route, and the necessary clearance from all metal parts
should be secured.
• Take care when carrying the unit by hand.
If the unit weighs more than 20kg, it must be carried by
two or more persons. Do not carry by the plastic straps,
always use the carry handle when carrying the unit by
hand. Use gloves to minimize the risk of cuts by the
aluminum fins.
• Dispose of any packing materials correctly.
Any remaining packing materials can cause personal
injury as it contains nails and wood. And to avoid danger
of suffocation, be sure to keep the plastic wrapper away
from children and to dispose after tearing it up.
• Be sure to insulate the refrigerant pipes so as not to
condense the ambient air moisture on them.
Insufficient insulation can cause condensation, which can
lead to moisture damage on the ceiling, floor, furniture
and any other valuables.
• When the air conditioner is operating (cooling &
drying operation) and the ventilator installed in the
room is also running, there is the possibility that drain
water may backflow as the room enters the negative
pressure state. Therefore, set up the opening port to let
air enter the room to provide appropriate ventilation
(for example, open the door a little). In addition, just
as above, set up the opening port if the room enters the
negative pressure state due to the aerator for the high
rise apartment etc.
• Install isolator or disconnect switch on the power
supply wiring in accordance with the local codes and
regulations.
• Do not install the unit in the locations listed below.
• Locations where carbon fiber, metal powder or any
powder is floating.
• Locations where any substances that can affect the unit
such as sulphide gas, chloride gas, acid and alkaline can
occur.
• Vehicles and ships.
• Locations where cosmetic or special sprays are often
used.
• Locations with direct exposure to oil mist and steam
such as kitchen and machine plant.
• Locations where any machines which generate high
frequency harmonics.
• Locations with salty atmospheres such as coastlines.
• Locations with heavy snow.
• Locations where the unit is exposed to chimney smoke.
• Locations at high altitude (more than 1000m high).
• Locations with ammonic atmospheres.
• Locations where heat radiation from other heat source
can affect the unit.
• Locations without good air circulation.
• Locations with any obstacles which can prevent inlet
and outlet air of the unit.
• Locations where short circuit of air can occur (in case of
multiple units installation).
• Locations where strong air blows against the vent of
outdoor unit. It can cause remarkable decrease in
performance, corrosion and damage of components,
malfunction and fire.
