Outdoor Unit

• Installation work must be performed following the instructions in this installation manual.

Improper installation may cause water leakage, electrical shock or ﬁ re. Check the

following items before operating the unit.

- Be sure that the pipe connection is well placed and there are no leaks.

- Check that the service valve is open. If the service valve is closed, it may cause

overpressure and result in compressor damage. At the same time, if there is a leak in

the connection part, it may cause air suction and overpressure, resulting in burst or

injury.

• The following must be certainly done during pump down.

• Do not incorporate air into the refrigeration cycle.

• Close the 2 service valves. Stop the compressor and remove the refrigerant pipe.

If the refrigerant pipe is removed when the compressor is operating and service valves are

opened, the refrigerant cycle will inhale unwanted matter such as air and the pressure in

the cycle becomes abnormally elevated. It may cause a burst or injury.

• Do not modify the power cable, connect the cable midway, or use a multiple outlet

extension cable. Doing so may cause contact failure, insulation failure, or excess current,

resulting in ﬁ re or electrical shock.

• If you detect any damage, do not install the unit. Contact your supplying dealer

immediately.

• Never modify this unit by removing any of the safety guards or bypassing any of the safety

interlock switches.

• Do not wash air conditioners with pressure washers.

Electric leaks may cause electric shocks or ﬁ res.

• Be sure to comply with local regulations/codes when running the wire from the outdoor

unit to the indoor unit. (Size of wire and wiring method etc.)

• When installing the air conditioner in a small room, provide appropriate measures to

ensure that the concentration of refrigerant leakage occur in the room does not exceed

the critical level. It is not dangerous refrigerant; it has not toxicity or combustibility.

However, a concentration above 0.3 kg/m³ as criterion still causes suffocation. The volume

of refrigerant charged to the multi system air conditioner is more than the volume charged

to a conventional individual system.

• Make sure drain hose insulation if cooling operation is used at sub-zero ambient

temperature.
