Receiving and Handling
Receiving
Upon receiving the product, check to make sure all
items are accounted for by referencing the bill of lading
to ensure all items were received. Notify the carrier if
any damage is noticed. The carrier will make notification
on the delivery receipt acknowledging any damage to
the product. All damage should be noted on all of the
copies of the bill of lading which is countersigned by the
delivering carrier. If damaged upon arrival, file a claim
with the carrier. Any physical damage to the unit after
acceptance is not the responsibility of the manufacturer.
Unpacking
Verify that all required parts and 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.
Storage
If a kitchen fan control center must be stored prior to
installation, it must be protected from dirt and moisture.
Indoor storage is highly recommended. For outdoor
storage, cover the control package with a tarp to keep it
clean, dry, and protected from UV (ultraviolet) radiation
damage.
Handling
Make sure the equipment does not suffer any heavy
vibration or knocks.
NOTE
Improper storage which results in damage to the unit
will void the warranty.
General Description
Description
The kitchen fan control center, or KFCC, is a
pre-engineered package designed to control the
operation of fans in a constant-volume kitchen. The
package consists of a cabinet encasing one or more fan
motor starters interlocked together for on/off operation.
Different fan, light and thermal switch combinations may
be provided to operate the kitchen hood fan(s), light(s),
and heating/cooling capabilities of the supply air. The
control center as a standard is equipped with additional
relays prewired to the fan starter(s). These additional
relays are capable of turning on the kitchen exhaust and
shutting down supply regardless of the present state of
the fans via integration of a fire system microswitch with
factory terminals. The control center can be equipped
with temperature interlock, designed to automatically
start kitchen fans and keep them running while heat is
being generated from the cooking appliances. Hood
systems should always be manually started before the
cooking equipment is turned on, but if forgotten the
interlock will safely trigger the fans to start once heat is
detected. Other options are available.
Purpose
The purpose of the KFCC is to provide a complete
control center to provide and house all fan starters. The
control center provides a common connection point
to interlock kitchen exhaust, supply, and hood lights
with the hood’s fire suppression system. The cabinet
is pre-engineered with terminal blocks for most field
wiring connections. The control center can also be
equipped with interlock between the exhaust fans and
cooking equipment, as to meet International Mechanical
Code (IMC) 2006 section 507.2.1.1. In this case, the
system will utilize a temperature sensor in the exhaust
duct collar or capture area in the hood to detect heat
generated from cooking operations and automatically
activate the exhaust fans if not already running.
Product Application
The KFCC is designed for both Type I and Type II
(grease and non-grease) constant-volume hood
systems, where starters are needed to activate fans.
The control center can operate both single and three
phase fans. Greenheck recommends using one KFCC
per hood system (activates all fans simultaneously).
When temperature interlock is provided in this package,
it is not to be used in conjunction with exhaust fire
dampers.
