DETERGENT PUMP OPERATION
Depending upon these factors, it may be necessary to ad-
just the detergent flow. Adjustment may be accomplished
by changing the cam to a different size. To change the
cam:
1. Loosen Allen set screw on brass cam.
2. Remove cam and replace with next size as required.
3. Cam #1 minimum setting. Cam #4 maximum setting.
NOTE: Cams are available from Gaylord Industries or your
Gaylord Certified Service Agency.
PREVENTIVE MAINTENANCE
As with any piece of fine equipment, a reasonable amount
of care must be taken to keep it in good working order:
1. Caution should be taken not to spill detergent on the ex-
terior of the pump.
2. A periodic check should be made of all fittings to guar-
antee their tightness.
NOTE : The detergent pump motor has sealed bearings and
will not require lubrication.
The Gaylord Ventilator ClearAir
TM
detergent pump is an
integral part of the wash-down system of The Gaylord
Ventilator and ClearAir
TM
unit. The pump is located within
the control cabinet unless otherwise specified. (Refer to
schematics on Pages 46 through 47.)
OPERATION
The detergent pump is started when the wash cycle begins.
The pump draws detergent up from the detergent tank,
pushing it through the copper tubing and into the hot water
line serving the ventilator.
NOTE: Some control cabinets are equipped with a low
detergent switch. If so equipped, the green light will flash
if the detergent tank is empty or if the detergent pump is
malfunctioning and detergent is not pumping. The digital
display reads "Low Detergent" and the text alternates from
"Fill Tank" and "Check Pump". If the detergent tank is filled
with water the detergent switch will activate as if there is
no detergent.
Initial Operation
To prime and operate the pump for the first time, it is recom-
mended that water be used instead of detergent to prevent
detergent from spilling in case of leaks at the system’s fittings.
Priming The Pump
The detergent pump is self-priming. Push the pump test
switch, located on the junction box of the motor, and hold
down until liquid climbs up the vinyl tubing and fills the pump
head. The pump will be operating properly when both upper
and lower poppet checks can be seen moving up and down
slightly. If the pump does not self-prime, an air lock may have
developed within the pump head and the following action
should be taken:
1. Hold down pump test switch and loosen top cap slightly
to allow air to be pushed out. Repeat as necessary until
liquid climbs up tube and fills pump head.
Note : Do not over tighten cap or damage to the pump
head will occur.
2. If the pump still does not work properly, check the follow-
ing:
A. Foot valve should be clean and immersed in the liquid.
B. Check all fittings to ensure an airtight system.
C. Poppet checks within the foot valve, pump head and
brass check valve should be clean and operating freely.
D. Detergent lines should be free and clear.
DETERGENT FLOW
Detergent flow is initially factory set according to the pipe
size of the control cabinet (refer to Detergent Consump-
tion chart). Generally, the factory setting will be sufficient
to provide adequate cleaning of the ventilator. However,
adequate cleaning is dependent upon a number of factors:
1.Temperature of hot water 4.Wash cycle time
2.Water pressure cycle 5.Frequency of wash cycle
3. Daily grease accumulation 6.Type of detergent
