Energy Recovery Filter System
General Description
Description and Purpose
The energy recovery filter system is an arrangement of
high efficiency grease filters with heat recovery coils to
be mounted in a commercial kitchen hood and piped
back to an existing water heater. While the smoke
and effluent generated off the commercial cooking
appliances will naturally be filtered, the heat generated
by the cooking process will be used to preheat water
being supplied to the water heater, thus reducing
operating expenses and the need for larger and more
expensive hot water heaters.
WARNING
Electrical shock hazard. Product contains electrically
activated components. This can cause equipment
damage, personal injury, or death. Service must only
be performed by personnel that are knowledgeable
in the operation of the equipment being controlled.
Read the installation, operation, and maintenance
instructions thoroughly before installing or servicing
this equipment.
DANGER
Always disconnect power before working on or
near the control panel provided. Lock and tag the
disconnect switch or breaker to prevent accidental
power up.
CAUTION
All field installation of electrical equipment must be
done to meet all NEC and electrical codes.

the correct quantity of each item have been received.
If any items are missing, report shortages to your local
representative to arrange for obtaining missing parts.
Sometimes it is not possible that all items for the unit
