Unit Installation Location
It is recommended that the ERV/HRV unit be located in a
conditioned space where it will be possible to conveniently
service the unit. Typically the ERV/HRV unit would be locat-
ed in the mechanical room or an area close to the outside
wall where the weather hoods will be mounted. A utility or
laundry room may be used if a basement area is not pres-
ent. Attic installations are not normally recommended for
ERV/HRV units due to:
• Complexity of work to install,
• Freezing conditions in the attic,
•
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” (635 mm) clearance is recommended so
the door can be opened. Four adjustable hanging straps are
provided for hanging the ERV/HRV except for the ERV5-
130 which comes with four mounting brackets.
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 ERV/HRV. The use of
an auxiliary drain pan under the installation should be con-
sidered.
CAUTION
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.
Suspending the Unit
This is a procedure for suspending the unit using adjustable
hanging straps. Use four screws and washers (field-provid
-
ed) to attach the hanging straps. The washer must be wider
than the eyelet of the grommet on the hanging strap. By
design, the adjustable hanging straps reduce the possibility
of noise, resonance, and harmonics.
1.
Insert the screws and washers (field provided) through
the hanging strap grommets and fasten to the joists.

S
hooks and reinsert the
machine screws.
NOTE: The following illustration of the unit may vary from
the unit you are installing.

3.
Hook the bottom grommets of the straps through the
S
hooks. Pull down vertically on the hand loops while
lifting up the bottom of the cabinet. Repeat at opposite
end of the unit.
NOTE: Do not pull the hand loops in a horizontal direction
(laterally with the unit) during installation or during
adjustment of the straps.
