• Use electric insulation between the duct and the wall
when using metal ducts to pass metal or wire laths or
metal plating into wooden buildings.
This may cause electric shock and a fire.
• Carry out drain piping properly to ensure complete
drainage.
If drain piping is not carried out properly, drain will not flow
out. Then, dirt and debris may be accumulated in the drain
piping and may cause water leakage. If it occurs, stop the
Heat Reclaim Ventilator unit and call your local dealer for
assistance.
• Do not locate the remote controller wherever there is a
risk of wetting.
If water gets into the remote controller there is a risk of elec-
trical leakage and damage to electronic components. It may
result electric shocks or a fire.
WARNING
(For moving and reinstalling/
repairing)
• Do not modify the Heat Reclaim Ventilator unit.
This may cause electric shock or a fire.
• Consult your local dealer regarding relocation and rein-
stallation of the Heat Reclaim Ventilator unit.
Improper installation work may result in leakage, electric
shocks or a fire.
• Do not disassemble or repair the unit yourself.

Improper installation may result in electric shocks or a fire.
Consult your local dealer.
• When the Heat Reclaim Ventilator unit is malfunctioning
(giving off a burning odor, etc.), turn off the power to the
Heat Reclaim Ventilator unit and contact your local dealer.
Continued operation under such circumstances may result
in a failure, electric shocks or a fire.
<CHECK LIST EXCEPT SAFETY CAUTION>
The items described below should be checked and ask your
