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).
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.

RNC95 Specifications
The RNC95 HRV (Heat Recovery Ventilator) has been designed
to allow the installer to choose between two possible positions
on the cabinet for the Stale Air Exhaust (from building) port.
Illustrations in this manual show standard (side mounted) port
location. The same specifications apply to both RNC95 setups,
regardless of which port position is selected.
Variable Port Location / Installation
(Model RNC95 only)
The exhaust return port collar is not factory installed. Installer
may choose either side mounted or alternate top mounted port
by simply removing one of the two knock-out plates and
attaching a port collar (supplied). To remove knock-out plate,
insert a utility knife into the knock-out slits and trace them
completely to puncture protective film underneath. Then, cut the
solid tabs between the slits, using tin snips or side cutters, and
remove the knock-out plate. If any protective film still blocks
the opening, remove it now.
In order to make the RNC95 as space efficient as possible, the
INDOOR supply and return ports are converted from round to
oval shape. Overall size of the port remains the same. Simply
bend a standard duct fitting to the correct shape, and attach to
the oval port using the same method as for a round port.
RNC95 Air Flow
Stale air enters the FRONT RIGHT side port. The air will pass
down the front half of the core, then up the back half of the core
and out the RIGHT REAR port.
Fresh outdoor air will enter the LEFT REAR port and pass down
the back half of the core. It will then pass up the front half of the
core, and out the LEFT FRONT port.

Option2-Vertical Duct Configuration Dimensions inches
The HRV can be installed horizontally or vertically as illustrated
on the following pages. The unit should be suspended using the
provided hanging straps. The unit must be level for proper
condensate drainage.
Sufficient clearance below the access door is required for
servicing the air filters and core. A minimum of 25" (635mm)
clearance is recommended so the door can be removed. Four
PVC reinforced polyester hanging straps are provided for
hanging the HRV.
