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. 14).
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
Step 1.—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.
Step 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.
