Safety Precautions
• Do not install the unit in a place with direct sunlight,
dangerous substances or where it is exposed to
inflammable gas leakage to prevent explosion, fire or
personal injury.
• Perform the installation securely referring to the
installation manual. Incomplete installation could
cause personal injury due to fire, electric shock and
water leakage or from the unit falling.
• Check first the following situations before starting the
operation during the installation.
– The pipe must be properly connected and make
sure there is no leakage.
– Service valves must be open. If compressor is
operated with the service valve closed, excessive
pressure may damage parts of the compressor. If
leakage occurs on any of the connection, air inflow
may also cause excessive pressure that could lead
to explosion.
• Stop the compressor before disconnecting the
refrigerant pipe for pump-down operation. If you
disconnect the refrigerant pipe while compressor is
operating with service valve open, air inflow will cause
excessive pressure in the refrigerant cycle that could
lead to explosion and personal injury.
• Be sure not to perform power cable modification,
extension wiring, and multiple wire connection.
– It may cause electric shock or fire due to poor
connection, poor insulation, or current limit
override.
– When extension wiring is required due to power
line damage, refer to "How to connect your
extended power cables" in the installation manual.
• Make sure to turn off the main power when setting up
the indoor unit electrical circuit or power cords. There
is a risk of electric shock.
• Make sure that proper circuit breaker and safety
switches are installed. Install a ground leakage
breaker depending on the installation place (where it
is humid). If not, it may cause electric shock.
• Do not install the unit by yourself (owners). Incorrect
installation of the unit could cause injury due to fire,
electric shock and water leakage or from the unit
falling. Consult a dealer or a qualified installer.

• Use the unit on a single outlet circuit. Do not share the
power outlet with other appliances. Obtain the consent
by a qualified installer before connecting the unit to
the power supply system. An all pole disconnection
from the power supply must be incorporated in the
fixed wiring with a contact opening of >3mm.
• Manufacturer is not responsible for accidents due to
incorrect installation.
• When you install the Air to water heat pump in a small
room, you consider a proper ventilation to prevent a
leakage level within the maximum permissible limit.
– In that case, you may die from suffocation by some
possibility.
• Fix the outdoor unit securely to prepare against strong
wind or earthquake.
– If the outdoor unit is not properly fixed, it turns over
and accidents may occur.
• If any gas or impurities except R410A refrigerant come
into the refrigerant pipe, serious problem may occur
and it may cause injury.
• Install the cables with supplied cables firmly. Fix them
securely so that external force is not exerted to the
terminal board.
– If the connection or fixing is incomplete, it can
cause trouble with a heat generation, electric shock
or fire and so on.
