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.
• Do not touch the plate heat exchanger of the unit. You may injure
yourself if you do so. If the plate heat exchanger must be touched for
some reason, first put on protective gloves and safety work clothing,
and then proceed.
• Do not climb onto or place objects on top of the outdoor unit. You may
fall or the objects may fall off of the outdoor unit and result in injury.
• When work is performed at heights, use a ladder which complies with
the ISO 14122 standard, and follow the procedure in the ladder’s
instructions. Also wear a helmet for use in industry as protective gear
to undertake the work.
• Before other parts of the outdoor unit, set the circuit breaker to OFF
without fail, and place a “Work in progress” sign near the circuit
breaker before proceeding with the work.
• Before working at heights, put a sign in place so that no one will
approach the work location, before proceeding with the work. Parts
and other objects may fall from above, possibly injuring a person
below. While carrying out the work, wear a helmet for protection from
falling objects.
• The refrigerant used by this hot water module is the R410A.
• The hot water module must be transported in stable condition. If any
part of the product is broken, contact the dealer.

around the packing carton. You may injure yourself if the bands
should break.
• The hot water module has been designed to be fitted at floor level.
Installation
• Install the hot water module securely in a location where the base can
sustain the weight adequately. If the strength is not enough, the unit
may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the hot
water module. Failure to follow these instructions may cause the
product to fall down or topple over or give rise to noise, vibration,
water leakage or other trouble.
• Carry out the specified installation work to guard against the
possibility of earthquake. If the hot water module is not installed
appropriately, a unit may topple over or fall down, causing an
accident.
• 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.
• Use forklift to carry in the hot water module units and use winch or
hoist at installation of them.
• Helmet must be worn to protect your head from falling objects.
Especially, when you work under an inspection opening, helmet must
be worn to protect your head from falling objects from the opening.
• The unit can be accessed from the service panel.
Refrigerant piping
• Install the refrigerant pipe securely during the installation work before
operating the hot water module. If the compressor is operated with
the valve open and without refrigerant pipe, the compressor sucks air
and the refrigeration cycles is over pressurized, which may cause a
injury.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut
after a long period, which may result in refrigerant leakage.
• 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 may be generated.
• When the hot water module has been installed or relocated, follow the
instructions in the Installation Manual and purge the air completely so
that no gases other than the refrigerant will be mixed in the
refrigerating cycle. Failure to purge the air completely may cause the
hot water module to malfunction.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not slack.
Water piping
• Do not install water pipes in a location that is susceptible to freezing.
Electrical wiring
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to carry out the electrical work of the hot water module. Under
no circumstances must this work be done by an unqualified individual
since failure to carry out the work properly may result in electric
shocks and/or electrical leaks.
• To connect the electrical wires, repair the electrical parts or undertake
other electrical jobs, wear gloves to provide protection for electricians
and from heat, insulating shoes and clothing to provide protection
from electric shocks. Failure to wear this protective gear may result in
electric shocks.
• Use wiring that meets the specifications in the Installation Manual and
the stipulations in the local regulations and laws. Use of wiring which
does not meet the specifications may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
• Connect earth wire. (Grounding work)
Incomplete grounding causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning
conductor or telephone earth wires.
• After completing the repair or relocation work, check that the earth
wires are connected properly.
• Install a circuit breaker that meets the specifications in the installation
manual and the stipulations in the local regulations and laws.
• Install the circuit breaker where it can be easily accessed by the
agent.
• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
7-EN 8-EN

–5–
• Under no circumstances the power wire must not be extended.
Connection trouble in the places where the wire is extended may give
rise to smoking and/or a fire.
• Electrical wiring work shall be conducted according to law and
regulation in the community and installation manual.
Failure to do so may result in electrocution or short circuit.
Test run
• Before operating the hot water module after having completed the
work, check that the electrical parts box cover (the front panel) of the
hot water module and service panel of the outdoor unit are closed,
and set the circuit breaker to the ON position. You may receive an
electric shock if the power is turned on without first conducting these
checks.
• If there is any kind of trouble (such as a check code display has
appeared, smell of burning, abnormal sounds, the hot water module
fails to heat or water is leaking) has occurred in the hot water module,
do not touch the hot water module yourself but set the circuit breaker
to the OFF position, and contact a qualified service person. Take
steps to ensure that the power will not be turned on (by marking “out
of service” near the circuit breaker, for instance) until qualified service
person arrives. Continuing to use the hot water module in the trouble
status may cause mechanical problems to escalate or result in
electric shocks or other trouble.
• After the work has finished, use an insulation tester set (500 V
Megger) to check the resistance is 1 MΩor more between the charge
section and the non-charge metal section (Earth section). If the
resistance value is low, a disaster such as a leak or electric shock is
caused at user’s side.
• Upon completion of the installation work, check for refrigerant leaks
and check the insulation resistance and water drainage. Then
conduct a test run to check that the hot water module is operating
properly.
Explanations given to user
• Upon completion of the installation work, tell the user where the circuit
breaker is located. If the user does not know where the circuit breaker
is, he or she will not be able to turn it off in the event that trouble has
occurred in the hot water module.
• If the fan grille is damaged, do not approach the outdoor unit but set
the circuit breaker to the OFF position, and contact a qualified service
person (*1) to have the repairs done. Do not set the circuit breaker to
the ON position until the repairs are completed.
Relocation
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to relocate the hot water module. It is dangerous for the hot
water module to be relocated by an unqualified individual since a fire,
electric shocks, injury, water leakage, noise and/or vibration may
result.
• When carrying out the pump-down work shut down the compressor
before disconnecting the refrigerant pipe. Disconnecting the
refrigerant pipe with the service valve left open and the compressor
still operating will cause air or other gas to be sucked in, raising the
pressure inside the refrigeration cycle to an abnormally high level,
and possibly resulting in rupture, injury or other trouble.
(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person”.
CAUTION

4Selection of installation place
Avoid installing in the following places
Select a location for the indoor unit where the cool or warm air will circulate evenly.
Avoid installation in the following kinds of locations.
• Saline area (coastal area)
• Locations with acidic or alkaline atmospheres (such as areas with hot springs, factories where chemicals or
pharmaceuticals are made and places where the exhaust air from combustion appliances will be sucked into the
unit).
Doing so may cause the heat exchanger and other parts to become corroded.
• Locations with atmospheres with mist of cutting oil or other types of machine oil.
Doing so may cause the heat exchanger to become corroded, mists caused by the blockage of the heat
exchanger to be generated, the plastic parts to be damaged, the heat insulators to peel off, and other such
problems to result.
• Locations where vapors from food oils are formed (such as kitchens where food oils are used).
The plastic parts to be damaged, and other such problems to result.
• Locations where an in-house power generator is used for the power supply.
The power line frequency and voltage may fluctuate, and the hot water module may not work properly as a result.
• On truck cranes, ships or other moving conveyances.
• The hot water module must not be used for special applications (such as for storing food, plants, precision
instruments or art works).
(The quality of the items stored may be degraded.)
• Locations where high frequencies are generated (by inverter equipment, in-house power generators, medical
equipment or communication equipment).
(Malfunctioning or control trouble in the hot water module or noise may adversely affect the equipment’s
operation.)
• Locations where there is anything under the unit installed that would be compromised by wetness.
(If the drain has become blocked or when the humidity is over 85%, condensation from the hot water module will
drip, possibly causing damage to anything underneath.)
• Locations where organic solvents are being used.
• The hot water module cannot be used for liquefied carbonic acid cooling or in chemical plants.
• Location near doors or windows where the hot water module may come into contact with high-temperature, high-
humidity outdoor air.
(Condensation may occur as a result.)
• Locations where special sprays are used frequently.
• Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interior
of the hot water module, it may spontaneously combust and start a fire.
• Locations such as living rooms and bedrooms where you can easily be bothered by noise. Noise may become
a problem.

WARNING
•Be sure to install the hot water module in a
place able to bear its weight.
If strength is insufficient, the unit may fall down
resulting in human injury.
•Perform specified installation work to protect
earthquakes.
If the hot water module is imperfectly installed, an
accident by falling or dropping may be caused.
CAUTION
• Drain water is discharged from the hot water
module. (Especially while operating)
Install the hot water module in a place with good
drainage.
• For installation, be careful of the strength and level
of the foundation so that abnormal sounds
(vibration or noise) are not generated.
• Be sure to install the hot water module in a place
strong enough to withstand its weight. If the base is
unstable, reinforce with a concrete base.
• The hot water module must be anchored on a level
surface. Use a level to check after installation.
• If the hot water module is installed near a room
where noise is a problem, using an anti-vibration
stand on the base of the unit is recommended.
1. Fix the hot water module with M8 anchor bolts at 4
positions. 20 mm projection is appropriate for an
anchor bolt.
