IMPORTANT

Please read this manual before installing the HRV

(Heat Recovery Ventilator).

Introduction

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

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.

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.

Port Configuration and Airflow	Model RNC95

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.

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.

Round port bent to oval

SIDE MOUNTED PORT	TOP MOUNTED PORT
standard location	alternate location

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.

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.

TO BUILDING

Connect drain hose to the two field installed spouts located on the bottom of the unit.

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.
