Page 4: Safety Precautions
- Operating the unit with a safety device whose settings have been changed may result in bursting, fire, or explosion. - Using safety devices other than those specified by MITSUBISHI ELECTRIC HYDRONICS & IT COOLING SYSTEMS S.p.A. may result in bursting, fire, or explosion. -
Page 5: Precautions For Transporting The Unit
Do not touch the refrigerant pipes and refrigerant line components with bare hands during and immediately after operation. - The refrigerant in the pipes will be very hot or very cold, resulting in frostbite or burns. Do not touch the electrical parts with bare hands during and immediately after operation. - Doing so may result in burns. -
Page 6: Precautions For Unit Installation
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 refrigerant piping made of phosphorus deoxidized copper (copper and copper alloy seamless pipes) that meets local requirements. Pipe joints should also meet local requirements. Keep the inner and outer surfaces of the pipes clean and free of sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminants. - Contaminants on the inside of the refrigerant piping will cause the refrigerant oil to deteriorate and cause the compressor to malfunction.

Page 19: Pipe Selection
・If the length of the pipe between the branching point and the outdoor unit exceeds 2 m (6 ft), provide a trap within 2 m (6 ft) from the branching point. The trap must be at least 200 mm (7-7/8 in) in height. (gas pipe only) If there is no trap, oil can accumulate inside the pipe, causing a shortage of oil and may damage the compressor. -
