Mounting the Unit
Unit may be installed in any orientation:
Orient the unit for the simplest duct layout and connections.
Note however that the door is equipped with slide-off hinges.
For the homeowner’s convenience it is helpful to orient the
unit so that the door does not drop off when it is unlatched.
Mounting the ERV on a concrete foundation wall:
Mount hanging bracket to the wall with appropriate concrete
anchors. Use pre-cut foam tape from small parts bag.
Remove backing and apply two pieces of foam tape equally
spaced along the unit’s mounting flange to be held by the
hanging bracket. Apply the other two pieces of foam over two
holes that will be used for fastening, on the other flange. The
tape should be applied in a “U” shape to cushion both the front
and back of the integral flanges. Lift unit and slide unit flange
into the hanging bracket.
Using metal flat washers, fasten
flange opposite hanging bracket to structure. Safety screws
should similarly be installed passing through the hanging
bracket and flange. Make sure the screws, which you must
supply, are properly selected for the loads and substrate
involved
.
Mounting the ERV to a stud wall:
Mount unit using supplied hanging bracket kit as described for
mounting to concrete foundation wall. Note that the hole
layout on the integral mounting flanges and the hanging
bracket are spaced for 16” or 24” on-center framing patterns.
Suspending the ERV from floor joists or trusses:
The unit may be screwed directly to joists or trusses using the
hanging bracket and integral flange. Mount as described for
mounting to concrete foundation wall. Note that the hole
layout on the hanging bracket is spaced for 16”, 19.2” and
24”on-center layouts.

Installing Outside Air and Exhaust
Air Ducts:
Ducts connecting the unit to the outside must be well-
insulated. Vapor barrier is required on both inside and outside
of the insulation.
Band or tape inner duct liner to inner flange of appropriate
collar. Drive a sheet metal screw through liner to secure duct
spiral wire to collar. Straighten insulation, and slide outer
duct jacket onto the outer flange of the duct collar. Secure
with band or tape.
CAUTION
The vapor barrier should be continuous and sealed against air
and moisture leakage! If not, condensation or ice may form in
cold weather on the duct surface or in its insulation!
The inlets and outlets should be screened against insects and
vermin and shielded from the weather to prevent the entry of
rain or snow.

♦
Do not locate the fresh air inlet where vehicles may be
serviced or left idling.
♦
The fresh air inlet should be at least ten feet away from
any exhaust such as dryer vents, chimneys, furnace, and
water heater exhausts or other sources of contamination or
carbon monoxide.
♦
Never locate the fresh air inlet inside a structure.
Installing Return Air (RA) ducts:
All the stale air returns are connected by ducts to the unit.
Generally, empty stud cavities are used for returns as is often
done with cold air returns for the furnace, using standard duct
boots to connect to six inch pipe at the bottom or top of the
wall cavity. Always be sure to seal all joints with duct sealant
or tape. Some local codes may require metal ducting all the
way from the boots to the stale air grilles. Use rigid ducts to
