WARNING During the pump down operation, make sure that the compressor is turned off before you remove the refrigerant piping. Do not remove the connection pipe while the compressor is in operation with 2 way or 3 way valve open. This may cause abnormal pressure in the refrigeration cycle that leads to rupture and even injury.

3. 6. Additional charging CAUTION Refrigerant suitable for a total piping length of 164 ft. (50 m) is charged in the outdoor unit at the factory. When the piping is longer than 164 ft. (50 m), additional charging is necessary. For the additional amount, see the table below. Total piping length [ft.

5-1/2 (140) 8-15/16 (227) Drain pipe mounting hole × 1 CAUTION Do not install directly on the ground, this may result in equipment failure. Make sure the height of the base is 2 in. (50 mm) from the ground. Otherwise, there is a risk that the drainage water will freeze between the device and the surface, disabling drainage. In places where the outdoor temperature drops to 32 °F (0 °C) or lower, the drain water may freeze and may stop up the drain or cause other outdoor unit trouble.
• When pipes are repeatedly bent or stretched, the material will harden, making it difficult to bend or stretch them any more. • Do not bend or stretch the pipes more than 3 times. 5. 1. 3. Connecting pipes CAUTION Be sure to install the pipe against the port on the indoor unit and the outdoor unit correctly. If the centering is improper, the flare nut cannot be tightened smoothly. If the flare nut is forced to turn, the threads will be damaged.
If a leakage is found, immediately repair it and perform a sealing test again. * Decrease the pressure of nitrogen gas before blazing After completing the sealing test, release the nitrogen gas from both valves. Release the nitrogen gas slowly. 6. ELECTRICAL WIRING WARNING Wiring connections must be performed by a qualified person in accordance with specifications. The rated supply of this product is 60Hz, 208/230V. Use a voltage within the range of 187-253V. 5. 3.
