1. Stale--air return from building connected to return--air duct
system.
2. Fresh--air intake connected to outdoor air inlet hood.
3. Exhaust--air connected to outdoor air exhaust hood.
4. Dampers are used to control air exchange with outdoor air
during defrost mode.
5. Mechanical filters trap dust contained in the air.
6. Heat recovery core is either a cross--flow type for compact
models, or a counter--flow type for high--efficiency models.
The core transfers heat between the 2 air streams. See Fig.
2.

7. Blowers bring in fresh--air from outside and exhaust stale--
air to outside.
8. Capacitor required for motor operation.
9. Condensation tray collects condensate from heat recovery
core.
10. Drainage tubes connect to sleeved grommets.
11. Electronic control circuit ensures proper unit operation.
12. Fresh air supply from HRV connect to return--air duct of
forced--air system.
13. Terminal connector block for wiring wall and timer con-
trols.
14. Electrical cord connects to standard 115V outlet.
Select Location
The HRV
should be located in a conditioned space
and in close
proximity to a fused power source. It should be easily accessible
for routine maintenance.
If HRV is installed independent of a forced--air system, unit should
be located near the center of the air distribution system. If HRV is
installed in conjunction with a forced--air system, unit should be
located next to (or close to) the indoor equipment.
UNIT INSTALLATION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
Do not install HRV in a corrosive or contaminated
atmosphere.
CAUTION
!
Mount Unit
The HRV can be suspended from floor joists using chains and 4
springs. Attach metal hanging bracket to all 4 sides of cabinet (see
Fig. 3). Unit should always be installed as level as possible.

Independent System Application
In the absence of a forced--air system and a typical duct system
layout, the HRV can be applied as an independent or stand alone
unit. To ensure comfort, this type of application involves running
both fresh--air and return--air registers (or stale--air pickup registers)
throughout the home.
