OPERATION AND

INSTALLATION MANUAL

C L E A N • F R E S H • A I R

NOTE: ALTHOUGH SOME MODELS
DIFFER IN OPERATION, THE BASIC
STEPS ARE SIMILAR.

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 installation, the
compatibility of the two pieces of equipment must be
confirmed, by measuring the airflow’s of the Heat/Energy
Recovery Ventilator (HRV/ERV), by using the balancing
procedure in this manual.

It is always important to assess how the operation of any
HRV/ERV may interact with vented combustion equipment
(ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).

NEVER

install an HRV/ERV in a situation where its normal

operation, lack of operation or partial failure may result
