Installation ENGLISH Plumbing materials and storage methods Pipe must be able to obtain the specified thickness and should be used with low impurities. Also when handling storage, pipe must be careful to prevent a fracture, deformity and wound. Should not be mixed with contaminations such as dust, moisture. Refrigerant piping on three principles Drying Should be no moisture inside Items Moisture Cleanliness No dust inside.
Installation Nitrogen substitution method Welding, as when heating without nitrogen substitution a large amount of the oxide film is formed on the internal piping. The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor. It prevents normal operation of the compressor. In order to avoid this problem, Welding should be done after replacing air by nitrogen gas. When welding plumbing pipe, the work is required.
Installation Before installing the decoration panel, always remove the paper template. The decoration panel has its installation direction. 1. Temporarily fix two decoration panel fixing screws (hexagon M5 screw) on the unit body. (Tighten by amount 10mm(3/8 inch) in length. The fixing screws (hexagon M5 screw) are included the indoor unit box. 2. Remove the air inlet grille from the decoration panel. (Remove the hook for the air inlet grille cord.) 3.
Installation Drain Piping • Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. • During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. • The outside diameter of the drain connection on the indoor unit is 32 mm(1-1/4 inch).
Installation Attention 1/50~1/100 2. Keep the drain hose downward up to 1/50~1/100 inclination. Prevent any upward flow or reverse flow in any part. MAX 700 mm (27-9/16 inch) 3. 5 mm (3/16 inch) or thicker formed thermal insulator is provided for the drain pipe. Thermal insulator (Local supply) Drain pipe (Local supply) Unit Elbow 4. Upward routing is not allowed. Drain pump 5. Be sure to check the drain pump for normal operation and abnormal noise when electrical wiring is complete.
