Safety Precautions WARNING • During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormally high pressure which could lead to equipment damage or and personal injury. • During installation, attach the refrigerant piping securely before running the compressor. If the refrigerant pipes are not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causing abnormally high pressure which could lead to equipment damage and personal injury. • Be sure to install a ground fault circuit interrupter breaker. Failure to install a ground fault circuit interrupter breaker may result in electrically shocks, or fire personal injury. CAUTION • Do not install the air conditioner where gas leakage would be exposed to open flames. If the gas leaks and builds up around the unit, it may catch fire. • Establish drain piping according to the instructions of this manual. Inadequate piping may cause water damage. • Tighten the flare nut according to the specified torque. A torque wrench should be used. If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage. • Do not touch the heat exchanger fins. Improper handling may result in injury. • Be very careful about product transportation. Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous. • Electrical work must be performed in accordance with the NEC/CEC by authorized personnel only.

Refrigerant Piping Work Refrigerant piping CAUTION • Use the flare nut fixed to the main unit to prevent it from cracking and deteriorating from age. • To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A.) • Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leakage. Align the centers of both flares and tighten the flare nuts 3 or 4 turns by hand. Then tighten them fully with the torque wrenches.

Use the remote controller for trial operation as described below. 2) After trial operation is complete, set the temperature to a normal level (78°F to 82°F (26°C to 28°C) in cooling mode, 68°F to 75°F (20°C to 24°C) in heating mode). 3) For protection, the system disables restart operation for 3 minutes after it is turned off. 1-3 Carry out the test operation in accordance with the operation manual to ensure that all functions and parts, such as fin movement, are working properly. • The air conditioner requires a small amount of power in its standby mode. If the system is not to be used for some time after installation, shut off the circuit breaker to eliminate unnecessary power consumption. • If the circuit breaker trips to shut off the power to the air conditioner, the system will restore the original operation mode when the circuit breaker is opened again. Trial operation from remote controller 1) Press “ON/OFF” button to turn on the system. 2) Press “TEMP” button (2 locations) and “MODE” button at the same time. 3) Press “MODE” button twice. (“ T ” will appear on the display to indicate that trial operation mode is selected.) 4) Trial operation terminates in approx. 30 minutes and switches into normal mode. To quit a trial operation, press “ON/ OFF” button. Test items Symptom Test items Check (diagnostic display on RC)
