The Lifebreath HRV (Heat Recovery Ventilator) is designed to
introduce fresh outdoor air into a building while exhausting an
equal amount of stale indoor air.
During the heating season, heat energy from the stale
exhausting air is transferred to the fresh, incoming air via
Lifebreath's patented aluminum core.
During the air conditioning season, the HRV will help cool the
incoming fresh air with the cooler stale exhausting air.
RNC electronics offers standard 2-speed operation of low/high.
There is also an installer selectable 2-speed operation of
medium low/high (refer to "Increasing Low Speed to Medium
Low" in this manual).
The RNC circuit board also includes an interlock relay which is
used to Interlock the HRV to an Air Handler/Furnace. Refer to
"Interlocking HRV Operation to an Air Handler/Furnace
Blower" in this manual.
We recommend using one of the Optional Main Controls (refer
to "Remote Control Devices" in this manual) for normal
operation.

IMPORTANT
Please read this manual before
installing the HRV
(Heat Recovery Ventilator).
CAUTION
Before installation, careful consideration must be
given to how this system will operate if connected to
any other piece of mechanical equipment, i.e. a forced
air furnace or air handler, operating at a higher static.
After installation, the compatibility of the two pieces of
equipment must be confirmed by measuring the
airflows of the HRV (Heat Recovery Ventilator) by
using the balancing procedure found in this manual.
NEVER install a ventilator in a situation where its
normal operation, lack of operation or partial failure
may result in the backdrafting or improper functioning
of vented combustion equipment.
NOTE
Due to ongoing research and product development,
specifications, ratings and dimensions are subject to change
without notice.
