INSTALLATION - FOR THE INSTALLING CONTRACTOR
1.
Unpack and Inspect
At the time the unit is received, all shipping containers
and their contents should be examined for damage. Any damage occurring in
shipment must be immediately reported to the carrier, an inspection report
completed and a claim filed at the receiving point.
The unit modular sections are shipped completely assembled and joined and,
where size permits, the electronic air cleaner ionizing-collecting cells are
shipped inside the cabinet. On large units, the upper tier of cells may be
shipped in separate containers. The wash control, detergent feeder and other
separate accessories are shipped in the containers as noted on the packing
list.
2. Position Air Cleaner Cabinet
If advantageous, to remove weight for ease in
handling, the filtration elements can be removed from their respective
cabinets. Position the unit in the designated location giving consideration
to the following points:
-
excluding the blower section, there are access doors on one side of the
section modules. Provide sufficient clearance in front of the doors on
at least one side for service and element removal. Normally the side on
which the factory installed blower motor starter is mounted is the
pre-planned side for single side access.
-
Level the unit to assure proper damage from the drain pans.
After the cabinet has been properly located, it may be secured into
place by bolting or welding. Reinstall any section elements removed
during installation making directional arrows concur with the designed
airflow through the cabinet.
3. Connect Adjoining Duct Work
When adjoining ducting is installed on the air entering side, the bottom of
the horizontal duct run should be relatively flat and sloped toward the
section housing drain pan for an 18 inch length. This will enable any wash
water splashback occurring during the washing operation to run back into the
drain pan.
Secure the adjoining ducting to the section housing utilizing the .375 inch
clearance holes provided. The seams should be made air and watertight by
caulking or gasketing.
Upstream ducting conveying warm air and subjected to cold temperatures must
be insulted to prevent excessive condensation.
4. Connect Drain
Refer to
fig 1 and
fig 4. The detergent system
should be located as close to the unit as practical in a level position.
Service space must be provided for periodical manual filling of the
detergent tank, and to gain access to the pump and motor assembly. When
positioned, the assembly may be secured in place at the predrilled factory
mounting pads, either by bolting or welding.
5. Connect
Drain
Connect a drain line to the 2” NPT couplings provided in the drain basins of
the impinger and electronic air cleaner sections in accordance with the
governing plumbing codes. The drain line must be sealed with a trap or other
means to prevent air bypass. If a trap is used, it should hold sufficient
water column to overcome the system air pressure and to assure that loss of
liquid from evaporation between cleaning periods will not break the seal.
The drain line should not be smaller than the drainpipe coupling, or it will
otherwise restrict the flow of water. See
fig 5.
6. Connect Water Wash Supply
The items furnished for field installations in the water wash supply are a
strainer, a back flow preventer (not supplied) and a detergent system. Refer
to the piping schematic
fig 5.
Unless otherwise specified, the water wash supply should be hot (140°
recommended WATER HEATER NOT SUPPLIED BY TRION)at the volume specified for
the given unit, and at a full flow pressure between 40 and 50PSIG.
|
WARNING! |
|
Adequate
precautions should be taken in the event the water supply,
detergent system and drains are subject to freezing temperatures
Although not required, a pressure gauge and a manual service
valve are recommended as shown in the diagram. The components
should be located within the system to provide for service
access. |
7. Mount Control
Mount the wash control, also containing the high voltage power supplies, in
the selected location. It must be mounted indoors out of the weather and
should be eye level to ease monitoring unit operation and as close to the
ATS unit as practical. Allow sufficient space in front of the access door
for service see fig 3
for mounting hold layout and dimensions.
8. Complete
Wiring
A. High Voltage Wiring
|
WARNING! |
|
EXERCISE
ALL THE NORMAL PRECAUTIONS WHEN WORKING WITH HIGH VOLTAGE AND
COMPLY WITH NEC AND ALL APPROPRIATE LOCAL CODES. |
The high voltage wiring entails interconnecting the power supplies with the
ionizing-collecting cells located in the electronic air cleaner section
cabinet. On multicell units, the wiring between the cells within a tier is
automatically made with intercell spring contacts.
Refer to the field wiring diagram, fig 6. Two 50 ft. (or the length
specified) high voltage leads, one for the ionizer and one for the
collector, are factory furnished. When the installation requires more than
one power supply. Ring type connectors have bveen factory installed at the
cell termination of the leads. After the leads have been run and cut to the
proper length, the slip on connectors, shipped on their respective power
supply terminals, should be secured by both crimping and soldering. For
working ease, the power supplies may be removed from their retaining slide
channels by removing the single bolt in the top corner of the rigid conduit
and must be of continuous run. DO NOT SPLICE. Knockouts are provided in the
section housing pilasters for conduit connection.
B. Primary Wiring
Refer to the field wiring diagram
fig 6. The primary wiring should be
completed using rigid conduit in accordance with prevailing electrical
codes.
The wash control is the main distribution point for all primary wiring. The
wiring includes the input supply to the control and the interconnections
between the control and the following components:
1. detergent feeder
2. manifold drive motors*
3. solenoid valves*
4. door interlocks*
5. blower motor starter / disconnect
6. temperatures sensor (where specified)
7. fire suppression control (when specified)
*One each for impinger and electronic air cleaner.
9. Fire
Suppression System
(when specified to be factory supplied)
The installation of the fire suppression nozzles, fire sensor device, the
components within the chemical cylinder housing and the interconnections of
the components has been completed at the factory. The authorized fire
control contractor must complete the remote mechanical “pull”, any other
hookup or tie in, final test and inspection. Refer to fire control system
outline drawing fig 7.
Mount the fire extinguishing system instructions in the designated area that
is conspicuously located. This should be in the kitchen or a well occupied
work area and is normally near the control.
10. Check Out for System Start-up
When the installation has been completed, assure that the equipment is ready
for start up by checking the following:
A. All construction debris is removed from the modular section
cabinets and the adjoining ductwork.
B. The inside of the power supply/control housing and the detergent
feeder tank is clear of any foreign material.
C. The drain lines from the section drain basin are clear and that
the line is completely connected to its point of termination.
D. All supply line piping is completed and wash water is available.
E. When required, assurance that the fire suppression system has been
inspected and tagged into service by an authorized person.
F. Supply line power is available and electrical wiring is completed
to the following components:
1. ATS control
2. blower motor starter
3. manifold drive motors
4. solenoid valve
5. door interlock
6. temperature sensor (when specified)
7. ionizing-collecting cells
8. fire suppression system, as applicable
G. NOTE: Do not put the initial supply of detergent into the
detergent tank. This is to be done after volume settings are made at
start-up.
