Location

The HRV/ERV must be located in a heated space where it will be
possible to conveniently service the unit. Typically the HRV/ERV
would be located in the mechanical room or an area close to the
outside wall where the weatherhoods 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 due to:

A

) the complexity of work to install

B

) freezing conditions in the attic

C

) difficulty of access for service and cleaning

Sufficient clearance at the front of the access door is required for
servicing the air filters and core. A minimum of 25" (635 mm)
clearance is recommended so the door can be opened. Four PVC
reinforced polyester hanging straps are provided for hanging the
HRV/ERV from the basement floor joists.

Suspending the HRV/ERV

The hanging straps should be attached to the unit at the top end
corners (mounting screws are already located on the HRV/ERV
case). Securely fasten the other end of the straps to the floor joists
with wide head nails (not supplied), making sure the unit is level.
The straps are designed to reduce the possibility of noise,
resonance or harmonics; therefore using the full length of the strap
between the HRV/ERV and the floor joists is recommended.

Illustration of Suspending the HRV/ERV

Electrical

The HRV/ERV should be plugged into a standard designated
(120VAC) electrical outlet with ground. It is not recommended
that an extension cord be used for this appliance. If further wiring
is required, then a licensed electrician should make all electrical
connections. It is recommended that a separate 15 amp/120 volt
circuit be used.

WARNING:

In order to prevent electric shock when cleaning or servicing the
HRV/ERV, it is extremely important to confirm the polarity of the
power line that is switched by the safety (disconnect) switch. The
hot line (black) is the proper line to be switched. To confirm the
proper polarity, use a voltmeter or test lamp to ensure there is no
power after the switch when the door is open. Check between that
point and ground (on the cabinet). This must be done as dwellings
are occasionally wired improperly. Always make sure that the
HRV/ERV is properly grounded.

*NOTE:

Front clearance of
25 inches (635 mm)
is recommended 
for servicing unit.

Improper installation, adjustment, alteration, 
service or maintenance can cause property 
damage, personal injury or loss of life.
Installation and service must be performed
by a qualified installer or service agency.

WARNING

Unit must be  installed level to ensure proper 

condensate drainage. Due to the broad range of 

installation and operational conditions, consider

the possibility of condensation forming on either

the unit or connecting ducting. Objects below the 

installation may be exposed to condensate.

CAUTION
