HRV/ERV Ventilators
Installing HRV/ERV unit
WARNING
Electric Shock Hazard.
Can cause injury or death.
Disconnect all remote electrical power
supplies before servicing. Unit may
have multiple power supplies.
Unit must be connected to a grounded
power supply in accordance with na-
tional and local codes.
CAUTION
Potential Water Damage.
Condensation can accumulate and cause water
damage to equipment, finished surfaces and struc-
tures.
Unit must be installed level to ensure proper con-
densation drainage.
If possible, avoid installing units above areas or
equipment that are sensitive to water damage.
Otherwise, the use of an auxiliary drain pan under
the installation is recommended.
Connect condensate drains in accordance with na-
tional and local codes.
P−Trap and tubing must be located below the HRV
door with a minimum of ¼" per foot downward slope
away from unit.
Location Selection
It is recommended that the HRV
/
ERV unit be located in a
conditioned space where it will be possible to conveniently
service the unit. Typically the HRV
/
ERV unit would be lo-
cated in the mechanical room or an area close to the out-
side wall where the weather hoods will be mounted. If a
basement area is not convenient or does not exist, a utility
or laundry room may be used.
Attic installations are not normally recommended for HRV/
ERV units due to:
S
the complexity of work to install,
S
freezing conditions in the attic,
S
difficulty of access for service and cleaning.
Sufficient clearance at the front of the access door is re-
quired for servicing the air filters and core. A minimum of
25" (635mm) clearance is recommended so the door can
be opened. Four PVC reinforced polyester hanging straps
are provided for hanging the HRV
/
ERV unit from the base-
ment floor joists.
Consideration should be given to unforeseen events
such as a clogged drain line or water intrusion due to
rain. This may cause water to form below the HRV/
ERV. The use of an auxiliary drain pan under the
installation should be considered.
CAUTION
Potential poor air quality results.
HRV3−195 & HRV3−300 defrost cycles will draw in air
surrounding the defrost intake opening and distrib-
ute throughout the home.
Avoid locating defrost intake duct/opening in an
area that may draw in undesirable temperatures or
poor air quality. This is often achieved by drawing in
air from a conditioned living space through a dedi-
cated duct installed on the defrost intake fitting.
