AIR CONDITIONER OPERATIONS AND PERFORMANCE

Outdoor Unit / OWNER'S MANUAL

Check before operation

• Check whether earth wire is disconnected or out of place.

• Check that air filter is installed to the indoor unit.

Heating capacity

• For heating, a heat pump system which sucks in outside heat air and discharges it into the room is adopted. If temperature of the outside air lowers, the heating capacity decreases.

• When temperature of the outside air is low, it is recommended to use other heating equipment together.

Turn on the power switch 12 hours or more before starting before operation.

WARNING

Defrost operation during heating operation

• If the outdoor unit has some frost during heating operation, the operation mode changes automatically to defrost mode to increase the heating effect (for approx. 2 to 10 minutes).

• During defrost operation, fans of the indoor and the outdoor units stop.

Protection for 3 minutes

• The outdoor unit does not operate for approx. 3 minutes after air conditioner has been immediately restarted after stop, or power switch has been turned on. This is to protect the system.

Main power failure

• If a power failure occurred during the operation, all operations stop.

• When restarting the operation, push ON/OFF button again.

Fan rotation of stopped unit

• While other indoor units operate, the fan on indoor units on “stand-by” rotates to protect the machine once per approx. 1 hour for several minutes.

Protective device (High pressure switch)

The high pressure switch stops the air conditioner automatically when excessive load is applied to the air conditioner.

If the protective device works, the operation lamp keeps lit but the operation stops. When the protective device works, check characters “ ” in the remote controller display part flash.

The protective device may work in the following cases.

• When suction or discharge port of the outdoor unit closed.

• When strong wind blows continuously against discharge port of the outdoor unit.

• When dust or dirt is excessively adhered to air filter of the indoor unit.

• When discharge port of the indoor unit is blocked.

Cooling/heating operation of Heat Recovery Multi air conditioner

• When the outdoor temperature goes out of the operable range, cooling or heating operation may not be performed in order to protect the equipment. In this case, “ ” goes on.

Characteristics of heating operation

• Hot air is not out immediately after the operation has started. After 3 to 5 minutes (differs according to room or outside temperature) has passed and the indoor heat exchanger has been warmed up, hot air blows out.

• During operation, the outdoor unit may stop if outside temperature becomes high.

• When other outdoor unit performs heating operation while the fan is operating, the fan operation may be

stopped temporarily to prevent blowing of hot air.

Characteristics of cooling/heating simultaneous operation

• If the outdoor temperature drops during operation, the fan of the outdoor unit may stop.
