4. Installing the refrigerant piping 4.1. Connecting pipes (Fig. 4-1) 45±2° When commercially available copper pipes are used, wrap liquid and gas pipes with commercially available insulation materials (heat-resistant to 100 C or more, thickness of 12 mm or more). The indoor parts of the drain pipe should be wrapped with polyethylene foam insulation materials (specific gravity of 0.03, thickness of 9 mm or more).

4. Installing the refrigerant piping 4. . Refrigerant piping (Fig. 4- ) Indoor unit 1. Remove the flare nut and cap of the indoor unit. 2. Make a flare for the liquid pipe and gas pipe and apply refrigerating machine oil (available from your local supplier) to the flare sheet surface.
. Drainage piping work .1. Drainage piping work (Fig. -1) Drain pipes should have an inclination of 1 100 or more. For extension of the drain pipe, use a soft hose (inner dia. 15 mm) available on the market or hard vinyl chloride pipe (VP-16 O.D. ø22 PVC TUBE). Make sure that there is no water leakage from the connections.
. Electrical work .1. Electrical work PKFY-P·VKM-E PKFY-P·VKM-E (Fig. -1) Connection can be made without removing the front panel. 1. Open the front grille, remove the screw (1 piece), and remove the electrical parts cover. 2. Securely connect each wire to the terminal board. * In consideration of servicing, provide extra length for each of the wires.
