Outdoor Unit
• 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.
• Install the Air to Water Heat Pump securely in a location where
the base can sustain the weight adequately.
• 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 a dedicated 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.
• 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.
If the 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.
If the 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.
• Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously
operating ignition sources (for example: open flames, an
operating gas appliance or an operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• The installation of pipe-work shall be kept to a minimum.
