!

WARNING

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

CAUTION

Denotes 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.

Finally, we want to congratulate you on your purchase of this excellent unit which will allow you and
your family to enjoy fresh air throughout your home for years to come!

CAUTION

Some activities create dust or vapors which may damage your unit. You must
therefore turn off and unplug your unit in the following situations:

• Major renovation work • Sanding (e.g. gypsum joints, etc.)

• Housing construction • Varnishing
During very heavy snowstorms or rain with strong winds, the unit should also

be turned off to avoid problems caused by snow or rain entering the unit, even if
it is equipped with an anti-gust intake hood.

Power disturbances or very short power failures may cause the electronic
control microprocessor to malfunction. If it does, disconnect the power plug
from the outlet and wait approximately 30 seconds, then plug it back in to
resume operation.

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 65°F. At least
once a year, the unit mechanical and electronic parts should be inspected by
qualified service personnel.

1. DEFROST MODE

When the outdoor temperature is below 23°F, recovery (of heat or energy) creates frost in the
module. To maintain its proper operation, the unit is programmed to defrost the recovery module.
The defrost frequency varies according to the outdoor temperature. Defrost lasts 7 minutes for
HRV150S, 6 minutes for HRV190S and 10 minutes for ERV180S models (or 10 minutes for all
models if set on “Extented Defrost”). During the defrost cycle, the unit shifts to maximum speed and
the dampers close.

After defrosting, the unit returns to the operating mode selected by the user.
