Air to Air Heat Exchanger
Installation Manual
Electrical wiring
• Only a qualified installer(*1) or qualified service person(*1) is allowed to carry out the electrical work of the Air to Air
Heat Exchanger. 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.
• When repairing the electrical parts or undertaking other electrical jobs, wear gloves to provide protection for
electricians and from heat. Failure to wear this protective gear may result in burn.
• 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 earthing causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning rods or earth wires for telephone 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. Use an exclusive power supply circuit for the Air to Air Heat Exchanger at the rated voltage.
• 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.
• Under no circumstances must the power cable be extended. Connection trouble in the places where the cable 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.
• When carrying out electric connection, use the wire specified in the Installation Manual and connect and fix the wires
securely to prevent them applying external force to the terminals. Improper connection or fixing may result in fire.
Test run
• Before operating the Air to Air Heat Exchan ger after havin g completed the work, check that the electrical control cover
and inspection 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.
• When there is some kind of trouble (such as when an error display has appeared, there is a smell of burning,
abnormal sounds are heard, or water is leaking) has occurred in the Air to Air Heat Exchanger, do not touch the Air
to Air Heat Exchanger 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 Air to Air Heat Exchanger in the trouble status
may cause mechanical problems to escalate or result in electric shocks, etc.
• After the work has finished, use an insulation test er set (500V 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.
• Upon completion of the installation work, check the insulation resistance. Then conduct a test run to check that the
Air to Air Heat Exchanger 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 Air to
Air Heat Exchanger.
• After the installation work, follow the Owner’s Manual to explain to the customer how to use and maintain the unit.
• If there is a danger of the Air to Air Heat Exchanger falling, do not approach the Air to Air Heat Exchanger 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 Air to Air Heat Exchan ger. It is
dangerous for the Air to Air Heat Exchanger to be relocated by an unqualified individual since a fire, electric shocks,
injury, water leakage, noise and/or vibration may result.
• The external air intake opening should be positioned away from the exhaust openings of combustion gases. The
intake of such gases could cause a lack of oxygen in the room.
The external air intake opening should not be pos itioned where discharged air may directly enter it.
A situation like this will lead to the room being contaminated and this may pose a health risk.
• Netting or something similar should be provided at the external air intake opening to prevent birds or other things
interfering with the unit.
• Nests or other foreign objects should be removed. That c ould cause a lack of oxygen in the room.
• To pierce the metal duct through the metal lath or the wire lath or the metal plate of the wooden facility, do not forget
to insulate electrically between the duct and the wall. Otherwise, it would cause an electric shock or an electric
leakage.
• Install the outdoor duct in a falling gradient toward the outside so as to prevent water from coming in. If it is not
installed so, the building is likely to be flooded, wetting the household effects.
• Heat-insulate the outdoor duct (including the indoor side, if necessary) to prevent dewing. If heat insulation is not
adequate, water likely goes indoor and wets the household properties.
• When it is high humid and high temperature inside the ceiling, a ventilation system must be installed inside the ceiling.
Otherwise, it could cause a fire or an electric leakage.
• Install the power line and the connecting line with accuracy so the power source cover may not float. If the installation
of the electrical control cover is inappropriate, the pin connection area is likely to cause a heat generation, a fire and
an electric shock due to dust or powder.
• Do not use the unit at the other voltages than the rated one. It could cause a fire or an elec tric sho ck.
• Do not install the unit in locations with large amounts of oily smoke, such as food preparation areas. It could cause a
fire.
• Do not install the unit at the place of a high temperature or a flame.
It could cause a heat generation or a fire.
• Do not install in locations with high humidity, such as close to bathroom or other similar environment. It could cause
an electric shock or an electric leakage or other troubles.
• Install an earth leakage breaker that is not tripped by shock waves.
If an earth leakage breaker is not installed, an electric shock may be caused.
• Do not install the unit and inside air int ake in a place such as a machin e factor y, chemi cal pl ant, or r esearc h insti tute,
where acids, alkaline, organic solvents, or coating materials are handled and toxic gases and/or corrosive gases may
be produced.
Otherwise gas poisoning may occur and/or the inside of the unit may be eroded or deteriorated. The deterioration
and erosion may result in an fire.
• After installation, switch off the circuit breaker for safety if the unit will not be used for a long time.
• Attach the parts such as the inspection cover securely.

Do not install the Air to Air Heat Exchanger in a place where flames can come into contact with the unit.
If the Air to Air Heat Exchanger is used for a long time without observing the conditions above, deterioration or
deformation of resin parts will occur and a malfunction may result.
• Dewing and frosting.
• In cold regions, the surface of the unit or the duct connector may be affected by condensation or frosting
depending on the outdoor air conditions or temperature/humidity of the ceiling cavity even though the
conditions for use are observed. In this case, add a heat insulator.
• Do not install the unit in a place where there is something that must not become wet. Depending on the
temperature or humidity of outdoor air and the installation place, water droplets may fall from the unit.
• As shown in the figure to the below, suppose a high temp absorbing air condition A and a low temp absorbing
air condition B are plotted on the air line figure, then a high temp a ir A is heat-exchanged by the unit and goes
out of the saturation curve as shown by Point C. In this case, the unit will be dewed o r frosted . To avoid th is,
heating a low temp air B up to B’ is required so as to get C’ below the saturation curve, before usin g the unit.

Duct Installation
• Duct installation is necessary to protect against access to live parts, rain water or contact with moving parts.
• Seal the junction of an adaptor and a duct with an aluminium tape firmly to prevent any air leakage.
• The room intake opening should be positioned as far as possible from the indoor supply opening.
• Use the specified ducts. (See the Model List)
• Install two outdoor ducts so they will be in the down gradient toward outdoor to prevent water from coming in.
(Gradient: 1/100~1/50) (See the figure below)
Heat-insulate two outdoor ducts (including outdoor air and exhaust air duct) to prevent dewing.
(Material: Glass Wool, Thickness-25mm) (See the figure below)
To pierce the metal duct through the metal lath or the wire lath or the metal plate of the wooden facility, insulate
electrically between the duct and the wall. (Refer to the laws and regulations of the country concerned and the
technical standard.)

• The hanging bracket does not need to be replaced.
• The printed image is reversed.
1) Hang the hanging bracket on the hanging bolt,
then adjust the nut so that the unit is level.
2) Use a double nut and fasten it firmly so that the
nut does not become loose.
• If the unit is not installed properly, it will vibrate
and may pose a hazard.
• If the unit is not level, the damper unit will not
work properly.
• Install the unit firmly enough to support its own
weight.
