GENERAL
This Heat Recovery Ventilator (HRV) is designed
to provide fresh air into the building while exhaust-
ing an equal amount of stale air.  During the winter
months, the incoming cold fresh air is warmed by
utilizing the heat recovered from the stale air be-
fore it is exhausted to the outdoors.  During sum-
mer months when the indoor space is air condi-
tioned, the Heat Recovery Ventilator will help in cool-
ing the incoming fresh air with the stale air that is
being exhausted.

These instructions are intended as a general guide
and do not supercede local codes in any way.  Con-
sult authorities who have jurisdiction before install-
ing.
