COMPONENT DESCRIPTION
The following listed items are components of HRVCCLHU. (See
Fig. 8)
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. Mechanical filters trap dust contained in the air.
5. 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.
6. Blowers bring in fresh air from outside and exhaust stale air to
outside.
7. Electronic control circuit ensures proper unit operation.
8. Fresh air supply from HRV connected to return air duct of
forced air system.
9. Terminal connector block for wiring wall and timer controls.
10. Electrical cord connects to standard 115-v outlet.
