INTRODUCTION
The Energy/Heat Recovery Ventilator (ERV/HRV) is used to
exchange indoor stale air with outside fresh air. The unit is
equipped with a special energy/heat recovery core which transfers
both sensible and/or latent heat between the fresh incoming air and
stale exhaust air. The cross--flow design core allows entering and
leaving air streams to transfer heat and/or latent energy without
mixing (See Fig. 3).

(Bottom view with access door removed)
The model operates at 2 airflows, 50 CFM in low speed and 100
CFM in high speed. This unit comes in two configurations, vertical
or horizontal. Special attention should be given to duct application,
balancing the ERV/HRV, and locating unit for easy access and
routine maintenance.
INSTALLATION CONSIDERATIONS
Inspect Equipment
Move carton to final installation location. Remove ERV/HRV from
carton taking care not to damage unit. Remove all packaging and
inspect unit for damage. Remove parts bag from inside unit. File
claim with shipping company if shipment is damaged or
incomplete. Check to make sure ERV/HRV unit matches Fig. 1 or
Fig. 2.
Select Location
The ERV/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 ERV/HRV is installed independent of a forced--air system, unit
should be located near the center of the air distribution system. If
ERV/HRV is installed in conjunction with a forced--air system, unit
should be located next to (or close to) the indoor equipment.
COMPONENT DESCRIPTION
The following listed items are components of ERVCCSHA (See
Fig. 4).
1. Exhaust--air connected to outdoor air exhaust hood.
2. Fresh--air intake connected to outdoor air inlet hood.
3. Fresh--air supply from ERV connected to return--air duct of
forced--air system.
4. Mechanical filters trap dust contained in the air.
5. Energy recovery core is a cross--flow type. The core trans-
fers 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. Stale air return from building connected to return--air duct
system.
