Wash System – Troubleshooting
Inadequate Washing of the ESP Cells
Inadequate washing of the ESP Cells may be caused by several conditions such as low hot water
temperature, inadequate amount of hot water, low water pressure, type of detergent, ratio of detergent to
water, frequency of the wash cycle, length of the wash cycle, length of the delay between wash cycles,
clogged spray nozzles, and problems with the oscillating wash manifolds. Corrective actions for many of
these items are covered in the Troubleshooting the Wash System Charts beginning on page 4-31. Items
not covered in these charts are as follows:
1.
Frequency of Wash Cycle
The wash system is designed to remove daily accumulations of smoke and grease particles in the ESP Cells.
If the ClearAir Unit is not washed a minimum of once during a cooking day, a smoke and grease buildup
could accumulate which the wash system cannot remove. If this occurs, the ESP Cells will no longer
remove the smoke particles.
2.
Length of Wash Cycle
The standard factory recommended wash time is 3 minutes. If the ESP Cells are not adequately cleaned it
may be necessary to increase the length of the wash cycle. The wash cycle may be programmed for
between 3-9 minutes. Refer to your specific Command Center Technical Manual for instructions on
programming the wash time.
3.
Length of Delay Between Wash Cycles
The delay time between the washes and rinses are programmed in the Command Center for a length of
time to allow the building’s hot water system to recover. The delay time may be programmed between 1
and 99 minutes. If the ESP Cells are not adequately cleaned cleaning may be improved by increasing the
delay time between the wash cycles to allow the detergent to soak on the Cells longer. Refer to your
specific Command Center Technical Manual for instructions on programming the delay time.
Important Note:
The wash, delay and rinse times may be programmed for different times as needed to adequately
clean the ESP Cells. The Command Center illustrated in this manual may not represent the model of
Command Center you have. Refer to the Technical Manual for your specific model of Command
Center for complete instructions on programming wash, delay and rinse cycle times. If you do not
have a Technical Manual for your Command Center, obtain the model number from the nameplate
on your Command Center and contact Gaylord Industries. Refer to page 1-1 for contact information.
