INTRODUCTION
The Heat Recovery Ventilator (HRV) is used to exchange indoor
stale air with outside fresh air. The HRV unit is equipped with a
special heat recovery core which transfers sensible heat between
the fresh incoming air and stale exhaust air.
It is required to locate the HRV in a conditioned space. Special
attention should be given to condensate drain, duct application,
balancing the HRV, and locating unit for easy access and routine
maintenance. The cross- flow design core allows entering and
leaving air streams to transfer heat energy without mixing.
LOCATION
Inspect Equipment
Move carton to final installation location. Remove the 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.
