LOCATION for MOUNTING
THE DUCTWORK SYSTEM
The Heat Recovery Ventilator must be located in
a heated space where the surrounding air temperature
does not fall below the freezing point. This is to prevent
freezing of the condensate lines. It is also very important
that the unit be mounted level (horizontal) in order that
the proper condensate drainage can occur. Failure to do
so will void warranty.
Typically, the HRV is positioned in the mechanical
room or area close to the outside wall on which the
weatherhoods will be mounted. Remember it needs a 120
VAC outlet to plug into (extension cords should not be used
except if required to test unit on initial startup). 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 complexity of work to preventfreezing
while allowing access for service and cleaning.
Sufficient clearance to the front of the HRV is required
for servicing of the airfilters and exchange cores. A minimum
of 25 in. (625 mm) clearance is recommended.
The four PVC reinforced polyester hanging straps
supplied are for mounting the HRV to the basement floor
joists. The hanger straps should be attached to the unitatthe
top end comers (mounting screws already located on the
HRV case). Securely fasten the other end of the straps to the
floor joists with wide head nails (not supplied) making sure
unit is level. The rubber straps are designed to reduce the
possibility of noise, resonance or harmonics, therefore using
thefull length ofthe strap between the HRV and thefloor joists
is recommended.
There are two prepunched holes in the bottom ofthe
HRV through which the drain pan connectors will protrude
onceyouplacethemasshown in Figure #1. They have been
stored insidetoavoid breakage ofthe connection pointduring
shipping. Do not forget the "O Ring" which seals the
connector to the pan. REMEMBER TO HAND TIGHTEN
ONLY the washer and lock nut which hold the drain
connector in place.
See Figure #1 for proper placement ofthe drain¬
age hose. The drain line must be located in an area that
is not subject to freezing and should be outletted into
floor drain, sink, standpipe or condensate pump. Make
sure the drain line slopes down to provide proper
condensate removal. Should no 'fall" be available, a
condensation pump may be used.
NOTE: A "P-Trap" should be made to
prevent odours from being drawn
in through drain line.
A well designed ducting system will allow the
HRV to operate at its maximum efficiency. Airflow will
be restricted by undersized ducting, use of too many
elbows, tees, bends, etc. Always try to keep duct runs
as short and straight as possible. When in doubt about
the airflow capacity of a duct's diameter, always install
the next larger size.
NOTE: Fully insulated ducting with an
integral vapour barrier must be
used on all runs passing through
unheated areas in order to avoid
condensation problems and
energy losses from the air streams.
We recommend NUFLEX from
NUTECH ENERGY SYSTEMS INC.
Check local codes for required
insulation values.
Four 6 in. (15 cm) ports on the HRV are for
attachment to the ductwork system. See Figure #1
for the function of these ports.
A
OUTSIDE WEATHERHOODS
The weatherhoods must have built-in "bird"
screens with 1/4 in. (.635 cm) minimum mesh to
prevent foreign objects from entering into the ductwork.
Do not use smaller mesh as it will be very susceptible
to plugging up. Flappers and dampers at the vents
must not be used as they will restrict air flow and often
“seize up". The preferred location of the outside
weatherhoods is:
• no less than 6 ft. (2 m) apart from each other
• at least 18 in. (46 cm) above ground level
• away from sources of contaminants, such as
automobile exhaust fumes, gas meters,
garbage cans, barbeques, etc.
• not exposed to prevailing winds, whenever
reasonably possible
The outside perimeter of the weatherhood
must be caulked.
