Congratulations!

You have made an excellent choice! The operating principle of your Heat Recovery Ventilator
or your Energy Recovery Ventilator will give you personal comfort you have never known
before.

We have prepared this User Guide especially for you. Please read it carefully to ensure you
obtain full benefit from your unit. Over the coming months, you will increasingly appreciate the
feeling of living in a more comfortable house.

Please take note that this manual uses the following symbols to emphasize particular
information:

!

WARNING

Identifies an instruction which, if not followed, might cause serious
personal injuries including possibility of death.

CAUTION

Identifies an instruction which, if not followed, may severely damage the
unit and/or its components.

NOTE: Indicates supplementary information needed to fully complete an instruction.
We welcome any suggestions you may have concerning this guide and/or the unit, and we

would appreciate hearing your comments on ways to better serve you.
Please forward all correspondence to us at the address indicated on the product registration

card included with this guide.

CAUTION

Make sure at all times that the outdoor intake and exhaust hoods are free
from any snow during the winter season. It is important to check your unit
during a big snow storm, so it doesn’t draw in any snow. If this is the case,
please operate the unit in the recirculation mode, or turn it OFF for a few
hours.
Do not use your unit during construction or renovation of your house or
when sanding drywall. This type of dust may damage your system.
Since the electronic control system of the unit is incorporated with a
microprocessor, it may not operate correctly because of external noise
or very short power failure. If this happens, unplug the unit and wait
approximately 10 seconds. Then, plug the unit in again.

CAUTION

When leaving the house for a long period of time (more than two weeks), a
responsible person should regularly check if the unit operates adequately.
If the ductwork runs through an unconditioned space (e.g.: attic), the unit
must operate continuously except when performing maintenance and/
or repair. Also, the ambient temperature of the house should never drop
below 18°C (65°F). At least once a year, the unit mechanical and electronic
parts should be inspected by qualified service personnel.

REPLACEMENT PARTS AND REPAIR

In order to ensure your ventilation unit remains in good working condition, you must use
Venmar Ventilation ULC genuine replacement parts only. Venmar Ventilation ULC genuine
replacement parts are specially designed for each unit and are manufactured to comply
with all the applicable certification standards and maintain a high standard of safety. Any
third party replacement part used may cause serious damage and drastically reduce the
performance level of your unit, which will result in premature failing. Venmar Ventilation
ULC also recommends to contact a Venmar Ventilation ULC certified service depot for all
replacement parts and repairs.
