70 troubleshooting Before calling for service, check the following: Problem Possible cause and points to check The system does not restart imme- diately. • After stopping the unit, it won’t restart im- mediately until 3 minutes have elapsed to protect the system. • When the electric plug is pulled out and rein- serted, the protection circuit will work for 3 minutes to protect the air conditioner. Noise • During unit operation or at stop, a swishing or gurgling noise may be heard. At first 2-3 minutes after unit start, this noise is more no- ticeable. (This noise is generated by refriger- ant flowing in the system.) • During unit operation, a cracking noise may be heard. This noise is generated by the case expanding or shrinking because of tempera- ture changes. • Should there be a big noise from air flow in unit operation, air filter may be too dirty. Bad odor • This is because the system circulates odors from the interior air such as the odor of furni- ture, paint, cigarettes. Mist or steam are blown out • During COOL or DRY operation, indoor unit may blow out mist. This is due to the sudden cooling of indoor air. In dry mode, fan speed can’t be changed. • In DRY mode, when room temperature be- comes lower than temperature setting +2 °C, unit will run intermittently at LOW speed re- gardless of FAN setting.

83 connection • Use the same method on indoor unit. Loosen the screws on termi- nal block and insert the plugs fully into terminal block, then tighten the screws. • Insert the cable according to terminal number in the same manner as the indoor unit. • If wiring is not correct, proper operation can not be carried out and controller may be damaged. • Fix the cable with a clamp. attaching a drain elbow • If a drain elbow is used, please attach it as fig- ure. (Note: Only on heat pump units.) using a vacuum cleaner as purging method 1. Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way's, connect the service port into the pro- jection of charge hose (low) for gauge manifold. Then connect the projection of charge hose (center) for gauge manifold into vacuum pump. 2. Open the handle at low in gauge manifold, operate vacuum pump. If the scale moves of gauge (low) reach vacuum condition in a moment, check 1 again. 3. Vacuum for over 15 minutes and check the level gauge which should read -0,1 MPa (76 cm Hg) at low pressure side. After the completion of vacuum, close the handle "LO" in gauge manifold and stop the operation of the vacuum pump. Check condition of the scale and hold it for 1-2 min. If the scale moves back in spite of tightening, make flaring work again, the return to the begin- ning of 3. 4. Open the valve rod for the 2-way valve to an angle of anticlockwise 90 degrees. After 6 seconds, close the 2-way valve and make the inspection of gas leakage. 5. No gas leakage? In case-of gas leakage, tighten parts of pipe. If leakage stops, then proceed to step 6. If it does not stop, discharge whole refrigerants from the service port. After flaring work again and vacuum, fill up prescribed re- frigerant from the gas cylinder. 6. Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly.

To prevent gas leakage, turn the service port's cap. The valve rod's cap for 2-way valve and 3 way's a little more than the point where the torque increases suddenly. 8. After attaching each cap, check for gas leakage around the caps. 2-way Valve 3-way Valve Open 90° 2-way valve 3-way valve 2-way valve 3-way valve 2-way valve 3-way valve Valve rod cap Valve rod cap Service port cap CAUTION • If the refrigerant of the air con- ditioner leaks, it is necessary to discharge all the refrigerant. Vacuum first, then charge the liquid refrigerant into air condi- tioner according to the amount marked on the name plate. • Please do not let other cooling medium except the specified one (R410A) or air enter into the cooling circulation system. Otherwise there will be abnor- mal high pressure in the system to make it crack and lead to personal injuries. Open Close Step 2 Step 3 Step 4 Step 6 Step 7
85 power source • The power source must be exclusively used for air conditioner (over 10 A). • In case of installing an air conditioner in a moist place, please in- stall a ground leakage breaker. • For installation in other places, use a circuit breaker as far as pos- sible.
