[. . . ] Place, where a distance marked is available as illustrated in the above figure. Power Source Before inserting power plug into receptacle, check the voltage without fail. A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it. Selection of pipe To this unit, both liquid and gas pipes shall be insulated as they become Iow temperature in operation. [. . . ] Insert from outside the room cable into left side of the wall hole, in which the pipe has already existed.

Connection of pipes To bend a pipe, give the roundness as large as possible not to crush the pipe , and the bending radius should be 30 to 40 mm or longer. The max vertical distance between the indoor unit and the outdoor unit is 5 m. Half union Flare nut Forced fastening without careful centering may damage the threads and cause a leakage of gas.

But the charge of refrigerant must be conducted by professional air conditioner engineer. Before adding additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant. 3. Connection Use the same method on indoor unit. Loosen the screws on terminal block and insert the plugs fully into terminal block, then tighten the screws. [. . . ] After 6 seconds, close the 2-way valve and make the inspection of gas leakage. Open Close 2-way valve 3-way valve 90 O 5 No gas leakage? In case of gas leakage, tighten parts of pipe connection. 6 If it does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder. [. . . ]
