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.
