Location Selection
The HRV must be located in a heated space where it will
be possible to conveniently service the unit. Typically the
HRV would be located in the mechanical room or an area
close to the outside 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 due to:
A) the complexity of work to install
B) freezing conditions in the attic
C) difficulty of access for service and cleaning
The HRV unit must be installed in a horizontal position as
shown in the illustration below. The unit should be sus-
pended using the provided hanging straps. The unit must
be level for proper condensate drainage. Sufficient
clearance below the access door is required for servicing
the air filters and core. A minimum of 25" (635mm) clear-
ance is recommended so the door can be removed. Four
PVC reinforced polyester hanging straps are provided for
hanging the HRV.
Suspending the Unit
The hanging straps should be attached to the unit at the
top end corners (mounting screws are already located on
the HRV case). Securely fasten the other end of the straps
to the ceiling 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 and the floor joists is recommended.
Weatherhood Location and Installation
Weatherhood kit includes two fixed-cover hoods with a
1/4” (6mm) mesh screen.
Exhaust Weatherhood Requirements
• At least 6' (2 m) from the ventilation air intake*
• At least 18" (460mm) above ground or above the
depth of expected snow accumulation*
• At least 3' (1 m) away from the corner of the building*
• At least 3’ away from gas meter, electric meter or a
walkway where fog or ice could create a hazard*
• Not into a garage, workshop or other unheated space
Installation
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
Electric shock hazard. Can cause
injury or death. Before attempting to
perform any service or maintenance,
turn the electrical power to unit OFF
at disconnect switch(es). Unit may
have multiple power supplies.
WARNING
Connecting Appliances to the HRV
The following appliances should not be connected to the
HRV:
• clothes dryer
• range top
• stovetop fan
• central vacuum system
NOTE: Connecting any of these to the HRV will
invalidate your warranty.
Clearances and Requirements
Before installation, careful consideration must
be given to how this system will operate if
connected to any other piece of mechanical
equipment, i.e. a forced air furnace or air handler,
operating at a higher static. After installation, the
compatibility of the two pieces of equipment
must be confirmed, by measuring the air flows of
the ventilator, by using the balancing procedure
found in this manual.
It is always important to assess how the operation
of any HRV may interact with vented combustion
equipment (i.e. Gas Furnaces, Oil Furnaces,
Wood Stoves, etc.)
NEVER install a ventilator in a situation where its
normal operation, lack of operation or partial
failure may result in the backdrafting or improper
functioning of vented combustion equipment!
WARNING
Lint, dust or grease will collect in the HRV
damaging the unit.
