Water or steam generates from the outdoor unit during heating. When the air conditioner is started, when the compressor starts or stops during operation or when the air conditioner is stopped, it sometimes sounds "shuru shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it is not a trouble.
Operate the unit with FAN mode on a fair day for about half a day to dry the inside of the unit well. Stop operation and turn off the power supply switch. Electric power is consumed even the air conditioner is in stop.
Defrosting operation When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat ex- changer of outdoor unit along with the drop of indoor temperature. Since the accumulated frost re- duces the effect of warming, it is necessery to automatically switch the operation to the defrosting mode.
Besides, construction expense is charged for removal or reinstallation. The capacity of air conditioner will decrease by contamination of inside of unit when it is used for about three years although depending upon the circumstances under which it is used, and so in addition to the usual maintenance service, special inspection/maintenance service is necessary.
INSTALLATION MANUAL FOR WIRE CONTROLLER 1. Remove upper part of wire controller Remove upper part of wire controller by press. PCB is mounted on lower part of wire controller, be careful not to damage it. 2. Install wire controller (1) For exposed installation, use 2 wood screws (accessory).
INSTALLATION MANUAL FOR WIRE CONTROLLER 3. Indoor unit wiring Connect terminals (A,B,C,D) on lower part of wire controller to terminals (A, B,C,D) on PCB of indoor unit. wiring from here Lower part of wire controller Upper part of wire controller Hint Tread surface of the terminal well so that shielding may not contact other part.
Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can also result in heat generation or fire. When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (R22) within the refrigeration cycle.

INSTALLATION MANUAL FOR INDOOR UNIT All Wiring of this installation must comply with NATIONAL, STATE AND LOCAL REGULATIONS. These instructions do not cover all variations for every kind of installation circumstance. Should further information be desired or should particular problems occur, the matter should be referred to your local distributor. BE SURE TO READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION.

INSTALLATION MANUAL FOR INDOOR UNIT 3. Preparation before installation (1) The position relation among hoisting screw (unit: mm) Down side Up side (2) If necessary, cut the opening installation and checking needed on the ceiling. (If has ceiling) Before installation, finish the preparation work of all the pipes (refrigerant, drainage) and wire (wire controller connection wire, indoor and outdoor unit connection wire) of indoor unit, so that after installation, they can be immediately connected with outdoor unit.

INSTALLATION MANUAL FOR ELECTRIC WIRING 8. The attentive matters in installation of air suction and discharging duct Recommend to use anti-frost and sound-absorbing duct. (locally bought) The duct installation work should be finished before the fitment of ceiling. The duct must be heat insulated. The specific air-discharging outlet should be installed at the place where the airflow can be reasonably distributed.

INSTALLATION MANUAL FOR ELECTRIC WIRING 10. The operation method of fan controller Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted. It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment). The air volume set should be in the operation air volume range.
INSTALLATION MANUAL FOR ELECTRIC WIRING 11. Refrigerant pipe [The air side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause water leakage.] The outdoor unit has been charged with refrigerant. When connect the pipe to the unit or dismantling the pipe from the unit, please follow the figure shown, use spanner and torque spanner together.
INSTALLATION MANUAL FOR ELECTRIC WIRING Electric wiring DANGER OF BODILY INJURY OR DEATH TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC CONNECTIONS. GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS. (1) Selection of size of power supply and interconnecting wires. Precautions for Electric wiring Electric wiring work should be conducted only by authorized personnel.
Selection of installation site It should be installed at places where it is firm enough to withstand the weight of the air conditioner to prevent falling. Typhoon and earthquake prevention. It should be installed according to specific requirements. Inasppropriate installation may lead to accidents.
