OPERATION AND
INSTALLATION MANUAL
For Models:
2500IFD
2500EFD
APPLICATION WARNING!!!
CAUTION
Before installation, careful consideration must be given to how the 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
of the two pieces of equipment must be confirmed, by measuring the airflow’s of the Heat Recovery Ventilator (HRV), by
using the balancing procedure in this manual.
It is always important to assess how the operation of any HRV may interact with vented combustion equipment.
NEVER install an HRV 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!!!
Do Not Attempt Installing Unit
Without First Reading Entire Manual.

INTRODUCTION
Table of Contents
These Heat Recovery Ventilators (HRVs) are designed
for commercial and industrial applications to provide
fresh air to a building while exhausting 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 before it is exhausted to
the outdoors. During summer months when the indoor
space is air conditioned, the Heat Recovery Ventilator
will help in cooling the incoming fresh air with the stale
air that is being exhausted.

Selecting the Correct Size HRV
Commercial and Institutional Requirements
For outdoor air requirements, ASHRAE has produced the Ventilation Standard 62-1989
that is used to determine acceptable ventilation rates. This standard is referenced directly or
used as “Good Engineering Practice” in most Code documents or design criteria.
