 CAUTION

This mark indicates procedures which, if improperly per-
formed, might possibly result in personal harm to the user, or 
damage to property.

This unit must be installed by qualified personnel with a capacity certificate for handling 
refrigerant fluids. Refer to regulation and laws in use on installation place.

The installation must be carried out in compliance with regulations in force in the place 
of installation and the installation instructions of the manufacturer.

This unit is part of a set constituting an air conditioner. It must not be installed alone or 
with non-authorized by the manufacturer.

This unit contains no user-serviceable parts. Always consult authorized service person-
nel to repairs.

When moving, consult authorized service personnel for disconnection and installation 
of the unit.

Be sure to use a dedicated power circuit. 
Never use a power supply shared by another appliance.

This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc 
is greater than or equal to 2.832 MVA at the interface point between the user's supply 
and the public system. It is the responsibility of the installer or user of the equipment 
to ensure, by consultation with the distribution network operator if necessary, that the 
equipment is connected only to a supply with a short-circuit power Ssc than or equal to 
2.832 MVA.

Do not install the unit in the following areas:
• For the installation conditions if installing in an area of high salt damage such as the 

coast, follow the Design & Technical Manual.

• Area filled with mineral oil or containing a large amount of splashed oil or steam, such 

as a kitchen. 
It will deteriorate plastic parts, causing the parts to fall or the unit to leak water. 

• Area that generates substances that adversely affect the equipment, such as sulfuric 

gas, chlorine gas, acid, or alkali. 
It will cause the copper pipes and brazed joints to corrode, which can cause refriger-
ant leakage.

• Area containing equipment that generates electromagnetic interference. 

It will cause the control system to malfunction, preventing the unit from operating 
normally.

• Area that can cause combustible gas to leak, contains suspended carbon fibers or 

flammable dust, or volatile inflammables such as paint thinner or gasoline. 
If gas leaks and settles around the unit, it can cause a fire.

• Avoid installing the unit at places where it will come into contact with animals’ urine or 

ammonia.

The units are not explosion proof and therefore should not be installed in explosive 
atmosphere.

Do not use the unit for special purposes, such as storing food, raising animals, growing 
plants, or preserving precision devices or art objects. It can degrade the quality of the 
preserved or stored objects.

Ground the unit. Do not connect the ground cable to a gas pipe, water pipe, lightning 
rod, or a telephone ground cable. Improper grounding may cause electric shock.

Perform draining for the unit according to the Installation manual. Check that the water 
is properly drained.
If the drain processing is improperly installed, water may drip down from the unit, wet-
ting the furniture.

Do not touch the fins with bare hands.

Be sure not to start or stop the operation of air conditioning with power breaker. Other-
wise, it may cause malfunction or water leakage.

When setting it up near the equipment that generates electromagnetic waves and the 
equipment that generates the higher harmonics wave, be sure to take measures against 
noise. Otherwise, it may cause malfunction or failure.

When energizing to the crankcase heater, please turn on the power 12 hours or earlier 
before operation begins. When the energizing time is short, it may cause failure. Be-
sides, please do not turn off power during the busy season.

This appliance is not intended for use by persons (including children) with reduced 
physical, sensory or mental capabilities, or lack of experience and knowledge, unless 
they have been given supervision or instruction concerning use of the appliance by a 
person responsible for their safety. Children should be supervised to ensure that they 
do not play with the appliance.

2.1.  Precautions for using R410A refrigerant

Pay careful attention to the following points:

Since the working pressure is 1.6 times higher than that of R22 models, some of the 
piping and installation and service tools are special. (See the table in the SPECIAL 
TOOLS FOR R410A section.)
Especially, when replacing a conventional refrigerant (other than R410A) model with 
a new refrigerant R410A model, always replace the conventional piping and flare nuts 
with the R410A piping and flare nuts.

Models that use refrigerant R410A have a different charging port thread diameter to pre-
vent erroneous charging with R22, R407C and for safety. Therefore, check beforehand. 
[The charging port thread diameter for R410A is 1/2 UNF 20 threads per inch.]

Be more careful than the installation of the refrigerant (other than R410A) models, not 
to enter foreign matters (oil, water, etc.) and other refrigerant into the piping. Also, when 
storing the piping, securely seal the openings by pinching, taping, etc.

When charging the refrigerant, take into account the slight change in the composition 
of the gas and liquid phases, and always charge from the liquid phase side whose 
composition is stable.

2.2.  Special tools for R410A

Tool name

Contents of change for R22 tool

Gauge manifold

Pressure is huge and cannot be measured with a conven-
tional gauge. To prevent erroneous mixing of other refriger-
ants, the diameter of each port has been changed.
It is recommended to use a gauge manifold with a high 
pressure display range -0.1 to 5.3 MPa and a low pressure 
display range -0.1 to 3.8 MPa.

Charging hose

To increase pressure resistance, the hose material and base 
size were changed.

Vacuum pump

A conventional vacuum pump can be used by installing a 
vacuum pump adapter.
• A conventional vacuum pump can be used by installing a 

vacuum pump adapter. 

• Be sure that the pump oil does not back flow into the 

system. Use one capable for vacuum suction of -100.7kPa 
(5 Ton, -755mmHg).

Gas leakage detector

Special gas leakage detector for HFC refrigerant R410A.

2.3. Accessories

Use connecting parts as required.
Do not throw away the connecting parts until the installation has been complete.
