2500IFD
2500EFD
TO BE COMPLETED BY CONTRACTOR AFTER INSTALLATION
Installation Date
IMPORTANT - PLEASE READ THIS
MANUAL BEFORE INSTALLING UNIT
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 airflow's of the Heat Recovery
Ventilator (HRV) Energy Recovery Ventilator (ERV) by
using the balancing procedure found 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 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!!!
