INSTALLATION OF THE INDOOR UNIT Preliminary Site Survey • Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes and regulations. • Voltage supply fluctuation must not exceed + 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause high supply fluctuation. - Page 10 Drain Piping Work • Drain pipe must be in downward gradient for smooth drainage. • Avoid installing the drain pipe in up and down slope to prevent reversed water flow. • During the drain pipe connection, be careful not to exert Indoor Unit extra force on the drain connector at indoor unit.

Page 12: Refrigerant Piping Work
REFRIGERANT PIPING WORK Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized by the perfect piping work. Piping length and elevation If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to flow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective. -

The working pressure of this new refrigerant is Tools exclusively for R410A are manifold valve, charging 1.6 times higher than conventional refrigerant (R22), thus hose, pressure gauge, gas leak detector, flare tools, torque proper installation / servicing is essential. -
Page 17: Special Precautions When Charging Unit With Copeland Scroll Compressors
SPECIAL PRECAUTIONS WHEN CHARGING UNIT WITH COPELAND SCROLL COMPRESSORS These precautions are intended for use with Copeland Scroll compressors only with R22, R407C, R134A, R404A, R507 and R410A refrigerants but are not applied to Copeland reciprocating compressors or competitive Scroll compressors. Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant in the system or if refrigerant is added too slowly. -
Page 18: Accessory Parts
ACCESSORY PARTS Short Duct Specification • The indoor unit is provided with air discharge and air intake “knock-out” hole for duct connection. However the connec- tion of the short duct for air discharge is possible on only one side. • The use of short duct for air discharge will improve airflow distribution if there is an obstruction (such as a lighting fixture) or in a long, narrow room or an L-shaped room. -
