[. . . ] Particularly note the relation between cable length and thickness. (Refer to page 11. ) 7) Always install a Residual Current Device (RCD) in wet or moist area. 8) The following may be caused by voltage drop. Vibration of a contactor, which will damage the contact point, fuse blowing, disturbance of the normal function of the overload. 9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and have an air gap contact separation of at least 3mm in each active (phase) conductor. If a power plug is not to be used, provide a Circuit Breaker/Fuse between power source and the unit as shown in adjacent diagram. CAUTIONS: After confirming the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power circuit 13 GD Midea Refrigerant Equipment Co.

Pull the lower left and right sides of the grille toward you and lift it up. 2. 6. 2. 2 In cases where the outdoor unit is installed below the indoor unit perform the following. Tape the piping, drain hose and connecting cable from down to up. Secure the tapped piping along the exterior wall using saddle or equivalent. 2. 6. 1. 2 To check the drainage. Pour a glass of water on the evaporator. Ensure the water flows through the drain hose of the indoor unit without any leakage and goes out the drain exit. 145psi) with dry nitrogen gas and close the cylinder valve when the gauge reading reaches 1MPa (Approx. CAUTION Manifol d set Pre s sure gau ge Indoo r unit Ou tdoor u nit Lo Hi Charge hose Nitr ogen g as cyli nder ( in vert ic al st a nding p osition ) To avoid nitrogen entering the refrigerant system in a liquid state, the top of the cylinder must be higher than its bottom then you pressurise the system. Usually, the cylinder is used in a vertical standing position. Do a leak test of all joints of the tubing (both indoor and outdoor) and both gas and liquid side service valves. Be sure to wipe off the soap with a clean cloth. After the system is found to be free of leaks, relieve the nitrogen pressure by loosening the charge hose connector at the nitrogen cylinder. When the system pressure is reduced to normal, disconnect the hose from the cylinder. Apply a soap water or a liquid neutral detergent 15 GD Midea Refrigerant Equipment Co. Ltd Service manual for Electrolux split Series on the indoor unit connection or outdoor unit connections using a soft brush to check for leakage of the connecting points of the piping. If bubbles come out, the pipes have leakage. Note: A: Lo stop valve B: Hi stop valve C and D: connections to the indoor unit.
