The manufacturer shall not assume any liability for the damage caused
by not observing the description of this manual.
WARNING
General
• Before starting to install the hot water module, read through the
Installation Manual carefully, and follow its instructions to install the
hot water module.
• Only a qualified installer or service person is allowed to do installation
work. Inappropriate installation may result in water leakage, electric
shock or fire.
• Do not use any refrigerant different from the one specified for
complement or replacement. Otherwise, abnormally high pressure
may be generated in the refrigeration cycle, which may result in a
failure or explosion of the product or an injury to your body.
• Before opening the front panel of the hot water module or service
panel of the outdoor unit, set the circuit breaker to the OFF position.
Failure to set the circuit breaker to the OFF position may result in
electric shocks through contact with the interior parts. Only a qualified
installer (*1) or qualified service person (*1) is allowed to remove the
front panel of the hot water module or service panel of the outdoor
unit and do the work required.
• Before carrying out the installation, maintenance, repair or removal
work, set the circuit breaker to the OFF position. Otherwise, electric
shocks may result.
• Place a "Work in progress" sign near the circuit breaker while the
installation, maintenance, repair or removal work is being carried out.
There is a danger of electric shocks if the circuit breaker is set to ON
by mistake.
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to undertake work at heights using a stand of 50 cm or more
or to remove the front panel of the hot water module to undertake
work.
• Wear protective gloves and safety work clothing during installation,
servicing and removal.

part of the product is broken, contact the dealer.
• When the hot water module must be transported by hand, carry it by
four or more people.
• Do not move or repair any unit by yourself. There is high voltage
inside the unit. You may get electric shock when removing the cover
and main unit.
• This appliance is intended to be used by expert or trained users in
shops, in light industry, or for commercial use by lay persons.
Selection of installation location
• When the hot water module 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.
• Do not install in a location where flammable gas leaks are possible. If
the gas leak and accumulate around the unit, it may ignite and cause
a fire.
• To transport the hot water module, wear shoes with additional
