Turn off and lock out the power to the ATS Control
System and associated systems. The fire suppression
system shall not be rendered inoperable during the
cleaning process.
Care shall be taken not to apply cleaning chemicals
on fusible links or other detection devices of the
automatic extinguishing system.
When cleaning procedures are completed all access
panels, doors, and cover plates shall be replaced. Dampers
and diffusers shall be positioned for proper airflow.
Water Wash Manifolds
The water wash spray pattern should be checked on
each nozzle every 4 to 6 months to ensure that a full
spray pattern is developed. Distorted patterns are
usually caused by dirt in the nozzle orifice, which can
be cleaned by inserting a small gage, soft copper wire
into the orifice. If any one manifold contains several
nozzles that are restricted, the drain plug at the idler
end of the manifold should be removed, after the
nozzles have been cleaned, then the manifold flushed
with clean water. The main supply line strainer and the
strainer in the detergent system should be checked
and cleaned. Check the wash manifold drive belt and
linkage connections and replace or tighten as required.
Power Supplies and Control
Examine the electrical components located inside
the control enclosure every 12 months for any
accumulated dirt or dust.
Exhaust Fan Bearings
Grease the two exhaust fan bearings at the grease
fitting provided every 4 to 6 months with Shell Alvania
#2, Texaco Multifac #2 or Mobilux #2. At this time,
examine the exhaust fan for any accumulated dirt and
clean as required.
Troubleshooting
WARNING
EXERCISE THE USUAL PRECAUTIONS
WHEN WORKING WITH HIGH VOLTAGE. THE
MAXIMUM OPERATING OUTPUT FROM THE
POWER SUPPLY IS 5.5MA (11.0MA WHEN
CONNECTED IN PARALLEL) AND 15,000VDC.
IF DOOR INTERLOCK SWITCHES ARE
CLOSED AND CIRCUIT IS ENERGIZED, DO
NOT TOUCH HIGH VOLTAGE. WHEN THE
CIRCUIT IS DE-ENERGIZED, ALWAYS BLEED
OFF REMAINING STATIC CHARGE WITH
AN INSULATED HANDLED SCREW DRIVER
BY SHORTING FROM THE HIGH VOLTAGE
CONNECTION TO THE FRAME OF THE
COLLECTING CELL.
WARNING: RISK OF ELECTRICAL SHOCK
THE SERVICING INSTRUCTIONS ARE FOR
USE BY QUALIFIED PERSONNEL ONLY. TO
REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT PERFORM ANY SERVICING
OTHER THAN THAT CONTAINED IN THE
SERVICE INSTRUCTIONS UNLESS YOU ARE
QUALIFIED TO DO SO.
Introduction
This section on trouble shooting provides a description
of potential malfunctions, their cause, location and cor-
rection. A Trouble Reference Chart listing the most prob-
able causes and corrections follows the general text.
Indicating lights are installed in the face panel of the
control to monitor the electrical operation of each
power supply and the ionizing-collecting cells they
energize. The quantity of power supplies per unit is
dependent upon unit size with at least one supply to
each cell tier. You should have a volt-meter with a
20KVDC high voltage probe.
Secondary Voltage (13KV)
The most common outage is a short in the high
voltage circuit and is best located through the process
WARNING
DO NOT USE HIGH PRESSURE CLEANING
EQUIPMENT TO CLEAN CELLS. THE
EXCESSIVE HEAT AND PRESSURE WILL
CAUSE THE PLATES TO WARP AND IN TURN
POSSIBLY CAUSE EXCESSIVE ARCING.
