• Upon completion of the installation work, check for the insulation
resistance. Then conduct a test run to check that the Air to Air Heat
Exchanger with DX Coil Unit is operating properly.
• After the work has finished, be sure to use an insulation tester set
(500 V Megger) to check the resistance is 1 MΩ or 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.
• Before starting to install the Air to Air Heat Exchanger with DX Coil
Unit, read carefully through the Installation Manual, and follow its
instructions to install the Air to Air Heat Exchanger with DX Coil Unit.
• Follow the instructions in the Installation Manual to install the Air to Air
Heat Exchanger with DX Coil Unit. Failure to follow these instructions
may cause the product to fall down or topple over or give rise to noise,
vibration, water leakage, etc.
• Before operating the Air to Air Heat Exchanger with DX Coil Unit after
having completed the work, check that the electrical control cover,
inspection cover and maintenance cover 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.
• Install the unit in the prescribed manner for protection against strong
wind and earthquake. Incorrect installation may result in the unit
falling down, or other accidents.
• Attach an anti bird net or the like to the outside air intake. Remove any
foreign object such as a nest; otherwise, an oxygen shortage may
occur in the room.
• Leave ample space between the outside air intake and the discharge
for combustion gas. Otherwise, an oxygen shortage may occur in the
room.
• When metallic ducts pass through a wooden construction covered
with a metal lath, wire lath, or metal plate, install the ducts so that they
are not electrically in contact with the metal parts of wooden
construction. If a short circuit occurs, a fire may result.
• Use the supplied or specified parts for installation. Otherwise, the unit
falling down, water leakage, an electric shock, or a fire may result.
• Perform anti-freezing work if the installation place is subject to
freezing. Otherwise, the solenoid valve or pipes are damaged and
water leakage may result.

• Do not install the unit in a place where the outside temperature
(especially around the unit or the air grill) falls below 0 °C. Otherwise,
water in the pipes, in the humidifying element, or in the solenoid valve
freezes and a breakdown or water leakage may result.
• If the ducts pass through a fire protection zone, use a noncombustible
duct and install a fire damper. The flame may spread when a fire
occurs.
• Install the ducts to the outside inclined downward so that rainwater
does not enter the ducts. Otherwise, water will enter the room and
household goods will become wet.
• Insulate the ducts from heat using a heat insulator to prevent
condensation. Otherwise, furniture may be damaged.
• If it is hot and humid in the ceiling cavity, install a ventilator.
Otherwise, a fire or a short circuit may result.
• Install drain pipes to drain water securely referring to the Installation
Manual. In addition, insulate the pipes from heat to prevent
condensation. Inappropriate piping results in water leaking into the
room and the ceiling, floor or furniture may be damaged.
Explanations given to user
• After the installation work, Follow the Owner's manual to explain to
the customer how to use and maintain the unit.
• Do not place any combustion appliance in a place where it is directly
exposed to the wind of Air to Air Heat Exchanger with DX Coil Unit,
otherwise it may cause imperfect combustion.
• For safety, turn off the unit if you do not use it for a long time. A fire or
an electric shock may result due to insulation degradation.
Relocation
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to relocate the Air to Air Heat Exchanger with DX Coil Unit. It
is dangerous for the Air to Air Heat Exchanger with DX Coil Unit to be
relocated by an unqualified individual since a fire, electric shocks,
injury, water leakage, noise and/or vibration may result.
• 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.
