Damaged air conditioners are not to be put into operation. In case of doubt, consult your supplier. Use of the air conditioner is to be carried out in strict compliance with the relative instructions set forth in the User's Guide.
Unless the circuit breaker is installed, it could cause elecrical shocks. Install on the place where can endure the weight of air conditioner. Bodily injury could result by a careless installation. WARNING Do not poke the air inlet or outlet with a bar, etc.
If the structure is not repaired immediately, the unit could topple down to cause apersonal injury. WARNING When the air conditioner is relocated, contact your dealer or a pro- fessional installer. Improper practice of installation could cause water leakage, electric shock or fire.
Isn't it warming up? page 9 When the air conditioner does not operate properly after you have checked the above mentioned items or when the following phenomenon is observed, stop the operation of the air conditioner and contact your sales dealer.
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 OUTDOOR UNIT <Heat Pump model/Cooling Only model > BE SURE TO READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD CAUSE SERIOUS INJURY OR DEATH, EQUIPMENT MALFUNCTION AND/OR PROPERTY DAMAGE. BE SURE TO READ INSTALLATION MANUAL FOR INDOOR UNIT WITH THIS MANUAL. 1.
INSTALLATION MANUAL FOR OUTDOOR UNIT 4. Refrigerant piping (1) Outline piping (2) Piping size Gas piping 15.88(5/8")x1.0mm Liquid piping 9.52(3/8")x0.8mm Install the removed flared nuts to the pipes to be connected, then flare the pipes. (3) Limitations for one way piping length and vertical height difference. One way piping length: less than 30m .
After attaching the each caps, check the gas leakage around the caps. CAUTION: If the refrigerant of the air conditioner leaks, it is necessary to make all the refrigerant out, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.
INSTALLATION MANUAL FOR OUTDOOR UNIT 5. Electric wiring 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.
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 (R407C) 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 (4) Preparation for suspending the unit (a) Size of hole at ceiling and position of hanging bolts <Combination with silent panel> (b) Hanger bolts installation Use care of the piping direction when the unit is installed. (Hanging bolt position) (Ceiling hole size) (Panel dimensions)
INSTALLATION MANUAL FOR INDOOR UNIT (5) Installation of indoor unit Fix the indoor unit to the hanger bolts. If required, it is possible to suspend the unit to the beam, etc. Directly by use of the bolts without using the hanger bolts. Note When the dimensions of main unit and ceiling holes does not match, it can be adjusted with the slot holes of hanging bracket.
INSTALLATION MANUAL FOR INDOOR UNIT When constructing drain piping for several units, position the common pipe about 100 mm below the drain outlet of each unit as shown in the sketch. Use VP-30(11/4") or thicker pipe for this purpose. Be sure to provide heat insulation to hard PVC pipes of indoor placement.
Use the rear fresh air inlet when the simultaneous intake and exhaust is conducted. (Side inlet cannot be used.) ii) Exhaust (Make sure to use also the suction.) Use the side exhaust port. Air conditioner main unit Heat inlet duct insulation...
