Location for Mounting
The ERV must be located in a conditioned space
where the surrounding air temperature does not
effect the ERV or its ducting. The unit must be
mounted level horizontal. The warranty could be
void if these conditions are not met.
Typically the ERV is positioned close to an outside
wall or the roof to simplify the connections and
keep the length of insulated ducting required for
the fresh air intake to a minimum.
A minimum clearance of 36 inches (90 cm) in front
of the ERV is recommended to service the
enthalpic cores and the filters. The ERV may be
mounted on an equipment platform providing there
is sufficient space to open the doors for servicing.
The Ductwork System
A properly designed ducting system will allow the
ERV to operate at its maximum efficiency. (Air flow
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.
NOTE: Fully insulated ducting with an integral
vapour barrier must be used on all runs
passing through unconditioned areas in
order to avoid condensation problems and
energy losses from the air steams.
All joints must be airtight, sealed and impervious
to moisture. See specification sheets for each unit
for exact duct sizes and location.
To minimize pressure drop and noise, galvanized
metal ducts, properly sized, are recommended.
Keep ducting as short as possible and use a mini-
mum of elbows and tees. Connecting sections and
shorter runs may be flexible ducting one size larger
than the metal equivalent. Use flexible duct con-
nectors at the ERV to avoid noise transmission.
All duct joints must be secured with screws, rivets
or duct sealant and sealed with aluminum duct
tape to prevent leakage.
