Kitchen Exhaust Systems
For safe and proper operation adhere to the
following instructions and procedures:
• Exhaust systems shall be operated during all
periods of cooking in restaurant applications.
• Filter-equipped exhaust systems shall not be
operated with filters removed.
• The posted instructions for manually
operating the fire extinguishing system shall
be kept conspicuously posted in the kitchen
and reviewed periodically with employees by
the management.
• Listed exhaust hoods shall be operated in
accordance with the terms of their listings
and the manufacture instructions.
• Cooking equipment shall not be operated
while its fire-extinguishing system or exhaust
system is out of service.
Initial Start-up
Check Out for System Start-up
Prior to equipment start-up, the fire extinguishing sys
-
tem employed in the ATS unit (and possibly adjoin
-
ing equipment) must be inspected by properly trained
and qualified personnel. This includes all actuation
components including remote manual pull stations,
mechanical or electrical devices, detectors, fire-actu
-
ated dampers, etc. These items shall be checked for
proper operation during the inspection in accordance
with the manufacturers listed procedures. In addition
to these requirements, the specific inspection require
-
ments of the applicable NFPA standard shall also be
followed. If required, certificates of inspection shall be
forwarded to the authority having jurisdiction.
When the installation has been completed, assure
that the equipment is ready for start-up by checking
the following:
• Inspect the inside of the adjoining ductwork and ATS
System to be sure it is clean and free of any debris or
construction materials. Especially note the opening
in the drain basin for any restrictions. The ducting,
where secured to the cabinet collars, should be
sealed watertight with either gasketing or caulking.
• Inspect the ionizing-collecting cells to see that all
of the ionizing blades are intact and that no large
pieces of foreign material are lodged between
the plates. Also verify that the cells are properly
installed in the cabinet with the spiked ionizing
blades located on the air entering side (Follow the
air flow directional arrows).
• Check that the high voltage wiring is connected to
the proper terminals, both at the ionizing-collecting
cells and on the power supplies.
• Be sure that the drain lines from the drain basins
are completely connected and properly terminated.
A trap or seal of some type must be incorporated
in the line to prevent air bypass.
• Check the water supply line to be sure water is
available and that the strainer, back flow preventer
(by others) and detergent system are properly
installed and connected.
• Be sure that electrical power is available, that the
wiring is completed, and that the exhaust fan is
ready to energize.
• Be sure that all access doors are closed.
• Close the system electrical supply switches,
making power available to the control and exhaust
fan motor starter. Check to verify exhaust fan
rotation is as shown on the rotation indicator arrow.
•
Turn the “ON-OFF” selector switch to the control
“ON”. The exhaust fan should run and the power
supplies should be energized. If the exhaust fan
does not start, press the Filtration Mode push-
button. Electrical arc-over within the ionizing-
collecting cells may occur. It is a normal occurrence
caused by accumulation dust from construction
or other sources in the cells and should soon
subside. If the arc-over is continuous and does not
subside, recheck the routing of the high voltage
leads between the power supplies and the cells.
The ionizer lead must be connected to the ionizer
and the connector lead to the collector. If arc-over
still occurs, or difficulty other than that outlined
above, refer to the Trouble Shooting reference
chart Section IV.
•
Be sure the detergent tank is clean, and then fill
the tank with detergent. To adjust the volume of
detergent used during the wash cycle, use an Allen
wrench to loosen the set screw on the knurled knob
of the control valve (see Figure 1). Make note of
the detergent level prior to a wash cycle. After a
wash cycle, use the chart to determine the amount
of detergent required for your system and adjust
accordingly. Turning the knob clockwise increases
