Wash System
Overview
The wash system is controlled by the Gaylord Command Center. The Command Center is mounted in the
Wash Control Cabinet which houses the valves, detergent pump, detergent tank and other plumbing com
-
ponents needed to operate the Wash Cycles (refer to Figure 2-15-1). In addition, two solenoid valves are
located on the top or near the top of each Ventilator section (refer to page A-5-1 for an illustration).
The two Ventilator wash manifolds, Extractor Wash and Plenum Wash, operate independently of each other
as the Extractor, Grease Canal and Grease Gutter typically need washing more frequently than the Plenum
area. Timers in the Command Center are factory programmed to initiate either the Extractor Wash or Ple
-
num Wash based on the number of hours the exhaust fan has been on. The Extractor Wash always comes on
while the exhaust fan is on and the Plenum Wash always comes on while the exhaust fan is off.

Frequency and Length of Wash
The frequency and the length of the Wash Cycles are primarily determined by the type of cooking equipment
involved; Light Duty, Light/Medium, Medium Duty, Heavy Duty, and Extra Heavy Duty as shown Table T-2-16-
1. The number of hours before the Wash Cycle starts, and the length of the Wash Cycle, are based on aver-
age conditions. Table T-2-16-1 shows an example of typical frequencies and length of the wash times. Actual
frequency and times necessary to adequately clean the Ventilator may vary depending on the following:
1.
Actual amount of cooking within the hours of fan operation.
2.
Type of food product being cooked.
3. Water pressure. Required pressure is 40 psi Min. to 80 psi Max.
4. Water temperature. Required temperature is 140 degrees F. Min. to 180 degrees F. Max.
5. Type of detergent. Refer to page 2-17 for recommend detergent.
6.
Ratio of detergent to water.
The number of Hours of Fan Operation and the Length of the Wash Cycle are programmed in the Command
Center. The length of the Wash Cycle, for the Extractor and the Plenum, can be increased or decreased,
independently, as needed to adequately clean the Ventilator. The minimum wash time is 3 minutes and
maximum is 10 minutes. The Hours of Fan Operation are factory set and cannot be changed however the
Duty of the cooking equipment can be changed to either increase or decrease the Hours of Fan Operation
