When installing in small rooms, take prevention measures not to exceed the density limit of refrigerant in the event of leakage, referred by the formula (accordance with ISO5149).
If the density of refrigerant exceeds the limit, please consult the dealer and install the ventilation system, othe
rwise lack of oxygen can occu
r, which can cause serious
accident.
•
Use the original accessories and the specified components for installation.
If parts other than those prescribed by us are used, It may cause water leaks, electric shocks, fire and personal inju
ry.
•
Install the unit in a location with good support.
Unsuitable installation locations can cause the unit to fall and cause material damage and personal inju
ry.
•
Ensure the unit is stable when installed, so that it can withstand earthquakes and strong winds.
Unsuitable installation locations can cause the unit to fall and cause material damage and personal inju
ry.

If the refrigerant comes into contact with naked flames, poisonous gas is produced.
•
Use the prescribed pipes, flare nuts and tools for R410A.
Using existing parts (for R22 or R407C) can cause the unit failure and serious accidents due to burst of the refrigerant circuit.
•
Tighten the flare nut by torque wrench with specified method.
If the flare nut were tightened with excess torque, this may cause burst and refrigerant leakage after a long period.
•
Do not open the service valves for liquid line and gas line until completed refrigerant piping work, air tightness test and evacuation.

Power supply with insufficient capacity and incorrect function done by improper work can cause electric shocks and fire.
•
Be sure to shut off the power before starting electrical work.
Failure to shut off the power can cause electric shocks, unit failure or incorrect function of equipment.
•
Be sure to use the cables conformed to safety standard and cable ampacity for power distribution work.
Unconformable cables can cause electric leak, anomalous heat production or fire.
•
This appliance must be connected to main power supply by means of a
circuit breaker or switch (fuse:16A) with a contact separation of at least 3mm.
•
Arrange the wiring in the control box so that it cannot be pushed up further into the box. Install the se
rvice panel correctly.
Incorrect installation may result in overheating and fire.
•
Use the prescribed cables for electrical connection, tighten the cables securely in terminal block and relieve the cables correctly to prevent overloading the terminal blocks.

•
Be sure to fix up the se
rvice panels.
Incorrect fixing can cause electric shocks or fire due to intrusion of dust or wate
r.
•
Be sure to switch off the power supply in the event of installation, inspection or se
rvicing.
If the power supply is not shut off, there is a risk of electric shocks, unit failure or personal inju
ry due to the unexpected start of fan.
•
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 installe
r.
If you install the system by yourself, it can cause serious trouble such as water leaks, electric shocks, fire.
•
Be sure to wear protective goggles and gloves while at work.
•
Earth leakage breaker must be installed.
If the earth leakage breaker is not installed, it can cause electric shocks.
•
Ensure that no air enters in the refrigerant circuit when the unit is installed and removed.

This may cause fire or electric shock due to defecting contact, defecting insulation and ove
r-current etc.
•
Do not bundling, winding or processing for the power cord. O
r, do not
deforming the power plug due to tread it.
This may cause fire or heating.
•
Do not run the unit with removed panels or protections.
Touching rotating equipments, hot surfaces or high voltage parts can cause personal inju
ry 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.
