5. FINDING A SUITABLE INSTALLATION AREA FOR HRV OR ERV
The HRV/ERV unit should be installed in a mechanical room or as close to an outside wall as possible. This
would assure a short run of insulated flexible duct.
The HRV/ERV unit must always be installed in an area where the air is tempered to avoid freezing of the
condensate line. The contractor should install the unit in an area that is very accessible to allow the homeowner
easy access for maintenance.
It is very important to install an electric receptacle (115v) near the HRV / ERV, a separate circuit breaker is
also recommended. You should have access to a condensate drain near the HRV/ERV to avoid the use of
condensate pump.
6. INSTALLATION OF THE HRV / ERV
The entire line of Imperial HRV/
ERV products is designed for
“Single Person Mounting
TM
”
(SPM). It will enable you to save
time and effort by offering you a
variable attachment system and
maximizing your basement space.
TIP TO INSTALLER
: Place HRV/
ERV on a stepladder to ease the
hanging process. If the unit is not
level, improper drainage will occur
and could lead to moisture and
leakage problems.
It is recommended to use
approximately 16 inches of flexible
duct (supplied in kit) between the HRV
or ERV and your rigid duct. The flex
duct is mounted the same way to the
HRV or ERV as the insulated flex.

figure 6.3 When completing the procedure
