[. . . ] 2. 6. 2. 3 In cases where the outdoor unit is installed above the indoor unit perform the following. Tape the piping and connecting cable from down to up. Secure the taped piping along the exterior wall. Form a trap to prevent water entering the room. Fix the piping onto the wall by saddle or equivalent. 2. 6. 1. 3 Drain piping The drain hose should point downward for easy drain flow. Do not make drain piping similar to diagrams shown below. 2. 6. 2 Form the piping 2. 6. 2. 1 Form the piping by wrapping the connecting portion of the indoor unit with insulation material and secure it with narrow vinyl tape and wide vinyl tape. If you want to connect an additional drain hose, the end of the drain outlet should be routed above the ground. Secure the drain hose appropriately. 14 GD Midea Refrigerant Equipment Co. Ltd Service manual for Electrolux split Series 2. 7 AIR PURGING 2. 7. 1 Air purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. Cooling (or heating if applicable) efficiency drops. Moisture in the refrigerant circuit may freeze and block capillary tubing. Water may lead to corrosion of parts in the refrigeration system. Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove any non-condensable substance and moisture from the system. 2. 7. 2 Air purging with vacuum pump 2. 7. 2. 1 Preparation Check that each tube (both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage. 2. 7. 2. 2 Leak test Connect the manifold set (with pressure gauges) and dry nitrogen gas cylinder to this service port with charge hoses. CAUTION Be sure to use a manifold set for air purging. If it is not available, use a stop valve for this purpose. The "Hi" knob of the manifold valve must always be kept closed. Pressurizes the system to no more than 1MPa (Approx. [. . . ] Correct the installation if not correct. Correct it. It's normal if the humidity in the room is over 85%. Correct if the commucication wire is not shielded wire or twisted with other wires. Replace if the LED is not on. 25 GD Midea Refrigerant Equipment Co.
