other than that outlined above, refer to the Trouble Shooting reference chart Section IV.
J.Be sure the detergent tank is clean, and then fill the tank 1/8 full with clean water. Do not fill with the detergent until
K.(Review this paragraph in its entirety before initiating the wash start button.)
Next, set the detergent volume setting per wash at the detergent feeder. Manually initiate the wash cycle by pushing the "Wash Start" button on the control. The wash control duration is 80 minutes and by means of a factory preset programmable logic controller (PLC) will sequence the washing events as previously outlined. When the detergent pump is energized, note the amount that is used by observing the reduction in the liquid level in the tank. The usage should be approximately 1 part of detergent to 20 parts of water. The water and detergent requirements for each unit model are listed in Table 1 on the Piping Schematic, Figure 5. To adjust the volume output from the pump, refer to the Detergent System Outline, Figure 4. The pump is a constant displacement type and the amount of detergent forced into the water supply to wash the unit is dependent upon the setting of the control valve in the bypass return line to the reservoir. The side of the translucent reservoir is marked with volume markers. Adjust the control valve to obtain the correct usage for the given unit model, then secure the setting with the Allen head set screw located in the valve adjustment knob. When the correct adjustment has been made, remove the remaining water from the reservoir and fill the tank with initial supply of detergent furnished.
L. When the wash control has cycled out, manually set the programmable timer relay (TR), or initiator clock, located in the control for automatic initiation of the washing operation. This setting can be tailored to the washing frequency best suited for the specific application and may be best explained by example.
Suppose the application of the equipment is to clean restaurant kitchen exhaust air. The collected contaminant to be washed away is of greasy nature, containing particulate such as smoke and fume from the grill, mist and vapors from the French Fryer, flour dust and other various matter that is created by normal kitchen operation.
In our example, the restaurant operates Monday through Saturday (closed Sunday) and opens daily at 6:00 a.m. and closes daily at 11:30 p.m. This busy schedule presents a relatively heavy dirt loading and being of greasy nature should be washed away daily. The best time being shortly after closing when the atmosphere has settled but before the greasy contaminant collected has had a chance to harden and setup.
From the above, a wash schedule of every day except Sunday at 1:00 a.m. can be established. As the duration of events preset at the factory is approximately 80 minutes, the cycle will end at approximately 2:20 a.m.
Prior to setting the initiator clock it will be necessary to charge the battery located inside the clock. This is accomplished by turning the selector switch on the front of the control to the "ON" position. A light inside the switch will glow. If it does not glow, check to be sure there is supply line power to the control. DO NOT PUSH THE WASH BUTTON. Allow the control to remain in the "ON" position for 24 to 36 hours
while the battery is charging.
To set the initiator clock, it is first necessary to set the existing time, then the program times that are to be initiated.
To set existing time:
1.Depress the reset (R) button to cancel out any previous settings.
2.Slide the
3.Push the (1 ... 7) button until the present day of the week is indicated.
