1-3. Precautions for unit installation Do not install the unit where combustible gas may leak. - If combustible gas accumulates around the unit, fire or explosion may result. Do not allow children to play with the packing materials. - Suffocation or serious injury may result. Cut up the packing materials before disposal. -
Page 7: Precautions For Electrical Wiring
1-5. Precautions for electrical wiring Include some slack in the power cables. - Failure to do so may break or overheat the cables, resulting in smoke or fire. Connections must be made securely and without tension on the terminals. - Improperly connected cables may break, overheat, or cause smoke or fire. Tighten all terminal screws to the specified torque. -
Page 8: Additional Precautions
1-7. Additional precautions Do not turn off the power immediately after stopping operation. - Wait for at least five minutes after the unit has stopped before turning off the power. Failure to do so may result in drain water leakage or the mechanical failure of sensitive parts. The unit must be periodically inspected by a dealer or qualified personnel. - Page 9 Use a vacuum pump with a check valve. - If the vacuum pump oil flows back into the refrigerant lines, the refrigerant oil may deteriorate and the compressor may malfunction. Keep tools clean. - If dust, dirt, or water accumulates on the charging hose or the flare processing tool, the refrigerant will deteriorate and the compressor will malfunction.
