+ Ask the customer to keep the Installation Manual together with the Owner's Manual.

+ Ask an authorized dealer or qualified installation professional to install/maintain the Air to Water Heat Pump.

Inappropriate installation may result in water leakage, electric shock or fire.

+ Be sure to connect earth wire. (grounding work) Incomplete grounding cause an electric shock. Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires. + Turn off the main power supply switch or breaker before attempting any electrical work. Make sure all power switches are off. Failure to do so may cause electric shock. Use an exclusive power circuit for the Air to Water Heat Pump. Use the rated voltage. Connect the connecting wire correctly. Ifthe connecting wire is connected in a wrong way, electric parts may be damaged. + When moving the Air to Water Heat Pump for the installation into another place, be very careful not to enter any gaseous matter other than the specified refrigerant into the refrigeration cycle. If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally high and it may resultingly causes pipe burst and injuries on persons. Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches. After unpacking the unit, examine it carefully if there are possible damage. Do not install in a place that might increase the vibration of the unit. To avoid personal injury (with sharp edges), be careful when handling parts.

Perform installation work properly according to the Installation Manual.

Inappropriate installation may result in water leakage, electric shock or fire.

When the Air to Water Heat Pump hydro unit is installed in a small room, provide appropriate measures to ensure that the concentration of refrigerant leakage occur in the room does not exceed the critical level. Tighten the flare nut with a torque wrench in the specified manner.

Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage.

Wear heavy gloves during the installation work to avoid injury.

Perform the specified installation work to guard against an earthquake.

If the Air to Water Heat Pump is not installed appropriately, accidents may occur due to the falling unit.

If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

After the installation work, confirm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might generate.

Electrical work must be performed by a qualified electrician in accordance with the Installation Manual. Make sure the Air to Water Heat Pump uses an exclusive power supply.

An insufficient power supply capacity or inappropriate installation may cause fire.

Use the specified wires for wiring connect the terminals securely fix.

To prevent external forces applied to the terminals from affecting the terminals.

Air to Water Heat Pump Outdoor Unit Installation Manual

+ When the Air to Water Heat Pump cannot cool or heat water well, contact the dealer from whom you purchased the Air to Water Heat Pump as refrigerant leakage is considered as the cause.

In the case of repair that requires refill of refrigerant, ask service personnel about details of the repair. The refrigerant used in the Air to Water Heat Pump is harmless.

Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in the room catches fire, it may generate toxic gas.

When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been completely repaired.

+ _Conform to the regulations of the local electric company when wiring the power supply.

Inappropriate grounding may cause electric shock.

+ Do not install the Air to Water Heat Pump in a location subject to a risk of exposure to a combustible gas. If a combustible gas leaks, and stays around the unit, a fire may occur.

+ Install the refrigerant pipe securely during the installation work before operating the Air to Water Heat Pump. Ifthe compressor is operated with the valve open and without the refrigerant pipe, the compressor sucks air and the refrigeration cycle is overpressurized, which may cause a burst or injury.

+ For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop the compressor before disconnecting the refrigerant pipe.

Ifthe refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor sucks air and the refrigeration cycle is overpressurized, which may cause a burst or injury.

À CAUTION New Refrigerant Air to Water Heat Pump Installation
