Safety Precautions CAUTION Do not install the system where the air outlet reaches directly the flora and fauna. Make sure to use a fuse of proper electric rating. It will not be good for their health. Use of steel or copper wire in place of a fuse is strictly prohibited because it could result in a trouble or fire accident. Neither stand on the air conditioner nor place something on it.

Malfunction please check the following things about your air conditioner before making a servie call. Unit fails to start Is the power source switch adjust cut in? Is city supply power in normal? Isn't the signal receiving Isn't the earth leakage section exposed to the breaker in action? direct sunlight or strong illumination? It is dangerous. Turn off the power supply switch immediately and contact the sales dealer. ON OFF Power stoppage? Power supply switch is not ON.
Malfunction The followings are not malfunction Water flowing sound is heard. Sh Sh uru ur u 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. Cracking sound is heard. This is caused by heat expansion or contraction of plastics. It smells. Air which blows out from the indoor unit sometimes smells.
Care and Maintenance Points to observe Turn off the power supply switch. Do not touch with wet hand. Do not use hot water or volatileliquid. ON Thinner Do not use! Benzine Tooth powder OFF CAUTION Do not open the inlet grill until fan stops completely. Fan will continue rotating for a while by the law of inertia after operation is being stopped. Cleaning CAUTION Do not dry the air filter with fire. Do not run the air conditioner without the air filter.
For Preparation of Heating("Hot Keep") "HOT KEEP"is operated in the following cases. When heating is started: In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating mode. Defrosting operation (in the heating mode): When it is liable to frost.
Is The Unit Installed Correctly Confirm the following items for safe and comfortable use of air conditioner.

Installation Manual For Indoor Unit (d) 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. Secure the elevation as high as possible (approx. 100 mm) (e) The stiff PVC pipe put indoor side should be heat insulated. A downhill grade of 1/100 or more VP 30 (f) Avoid putting the outlet of drain hose in the places with irritant gas generated.
Installation Manual For Indoor Unit The length difference among every duct is limited below 2:1. Reduce the length of duct as possible as can. Reduce the amount of bend as possible as can. Use heat insulation material to bind and seal the part connecting main unit and the flare part of air discharging duct. Perform duct installation work, before the fitment of ceiling. Bad example Bad example Good example 7.
Installation Manual For Indoor Unit 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. Special air discharging outlet Use screw bolt to fix The specific air-discharging outlet should be installed at the place where the airflow can be reasonably distributed.
Installation Manual For Indoor Unit 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. Figure I shows the position of fan controller in the electric box and operation method. After finishing the electric work, perform test run.
Installation Manual For Indoor Unit 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. When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil.
