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 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 (See Fig. 14, and 17 ---24).
Step 1.—Inspect Equipment
Move carton to final installation location. Remove 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
HRV unit matches Fig. 1 through 3 and 4 through 6.
