PRACTICAL
TIPS
• To prevent electrical shock, check
that the unit is unplugged before
doing any repairs or maintenance.
• A yearly inspection is recommended
to ensure the efficiency and trouble-
free use of your system. Run
through the system and verify the
different operating modes.
The motor - The motors are factory
balanced and lubricated for life.
They require no maintenance.
The unit - The inside of the unit
should be vacuumed yearly.
Be
careful not to damage any of the
mechanical components and elec-
trical connections.
Outside hoods - The outside hoods
need to be checked every season to
make sure there are no leaves or
insects blocking the airflow. Check
regularly that there are no pollu-
tants near the intake hood. Make
sure they are clear of any snow
accumulation during the winter
months.
FILTERS
The filters (2) need to be checked and
cleaned every three months or when
they appear dirty. Wash in warm
sudsy water (mild detergent) or use a
soft brush vacuum. The filters should
be replaced when they can no longer
be cleaned properly.

water. Rinse thoroughly. Handle with care. Hot water and a strong detergent will damage the heat recovery core.
