[. . . ] Install an exclusive branch circuit of the power. 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. Use optional parts for piping set or pipes covered with equivalent insulation material. [. . . ] Make sure once more the proper level of the plate, by hanging a thread with a weight from the central top of the plate, then fasten securely the plate with the attachment steel nail. Find the wall hole location A using a measuring tape A=80mm Fit the level line When the mounting plate is fixed side bar and lintel Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten the plate to the fixed mounting bar. Refer to the previous article, " position of wall hole. When the mounting plate is first fixed ", for the 2. Making a Hole on the Wall and Fitting the Piping Hole Cover Make a hole of 70 mm in diameter, slightly descending to outside the wall. Install piping hole cover and seal it off with putty after installation Indoor side Wall hole 70mm Outdoor side Thickness of wall (Section of wall hole) G Piping hole pipe 3. Installation of the Indoor Unit Drawing of pipe [ Rear piping ] Draw pipes and the drain hose, then fasten them with the adhesive tape [ Left Left-rear piping ] In case of left side piping, cut away, with a nipper, the lid for left piping. In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear piping which is marked on heat insulation materials. 3 35 Indoor unit 1. Insert the drain hose into the dent of heat insulation materials of indoor unit. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then connect them. Coat the flaring seal face with refrigerant oil and connect pipes. Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape Heat insulation material Lid for right piping Lid for under piping Lid for left piping Drain hose Piping Pipe supporting plate Indoor/outdoor electric cable Fix with adhesive tape Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape. [Other direction piping] Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according to the position of wall hole. When bending, be careful not to crash pipes. (Note: Only for heat pump unit. ) 6 Outdoor unit 6. Purging Method:To use vacuum pump 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 projection of charge hose (Iow) for gaugemanifold. Then connect the projection of charge hose (center) for gaugemanifold into vacuum pump. 2 Open the handle at Iow in gaugemanifold, operate vacuum pump. If the scale-moves of gause (Iow) reach vacuum condition in a moment, check 1 again. Tube(for R410A) Vacuum pump(for R410A) Gaugemanifold(for R410A) Anti countercurrent joint 2-way valve Liquid Side 3-way valve Gas Side Open 3 Vacuumize for over 15min. And check the level gauge which should read -0. 1 MPa (-76 cm Hg) at Iow pressure side. After the completion of vacuumizing, close the handle 'Lo' in gaugemanifold and stop the operation of the vacuum pump. Check the condition of the scale and hold it for 1-2min. If the scale-moves back in spite of tightening, make flaring work again, the return to the beginning 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. Open Close 2-way valve 2-way valve 3-way valve 3-way valve 90 O 5 No gas leakage? In case of gas leakage, tighten parts of pipe connection. [. . . ] After 6 seconds, close the 2-way valve and make the inspection of gas leakage. Open Close 2-way valve 2-way valve 3-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. 2-way valve HSU-22HV03/R2(DB) HSU-22HVA103/R2(DB) 2-way valve 3-way valve 6 Detach the charge hose from the service port, open 2-way valve and 3-way.
