Detergent Flow Ratio
The Detergent to water ratio is determined by the setting on the Adjustable Cam located on the end of the
motor shaft (Refer to Figure 4-46-1).
The Adjustable Cam may be adjusted from “0” to “6” with “0” being
no detergent pumping, “1” the lowest ratio of Detergent to water and “6” the highest ratio. The pump
comes from the factory set at either number “1”, “1.5” or the “2” position depending upon the total length
of Ventilator, in feet, the pump is serving. Refer to Chart C-4-47-1 for detergent consumption and factory
settings. Generally, the factory setting will be correct to provide efficient cleaning of the ESP Cells,
however, adequate cleaning is dependent upon a number of factors:
1.
Actual amount on cooking within the hours of fan operation.
2.
Type of food product being cooked.
3.
Water pressure. Required minimum pressure is 30 psi at the ClearAir Unit pressure gauge.
4.
Water temperature. Required temperature is 140°F. Min. to 180°F. Max.
5.
Length of Wash Cycle
6.
Frequency of Wash Cycle
7.
Delay between wash and rinse
8.
Type of detergent. Refer to page 4-8
for recommended detergent.
9.
Ratio of detergent to water.
If it is determined that more detergent is being used than necessary, or that a higher ratio of detergent to
water is required, the ratio may change by re-setting the Adjustable Cam to a lower or higher position. To
change the cam setting, proceed as follows (Refer to Fig. 4-46-1):
1.
Remove the plastic Protective Cover (not shown), that covers the Adjustable Cam Assembly, by
removing the cover screw.
2.
Loosen the Wing Nut approximately 1/8”.
3.
Turn the Adjuster Ring until the Pointer lines up with the desired number, or a point between the
numbers.
4.
While holding the Adjuster Ring tighten the Wing Nut.
