!
CA-3 & DA-3 Technical Manual 2018 www.insingermachine.com 800-344-4802
CAUTION:
V-cup seal on the drain overow tube may become
gummed which will not allow the overow tube to
seat properly. This will cause the drain to leak water.
Remove any build-up on the V-cup seal. When the
seal becomes worn, replace.
3. Flush scrap screens of matter.
4. Clean drain overow tube.
5. Clean suction strainers of build-up.
CAUTION:
Improper cleaning of suction strainers will cause
the pumps to cavitate. This will cause poor washing
results.
7. Rinse nozzles should be cleaned of matter.
8. Doors should be left open to allow drying of interior
surfaces.
WEEKLY CLEANING
1. The entire machine should be wiped down using
an industrial grade stainless steel cleaner.
2. Under the supervision of your detergent supplier
the machine interior must be properly de-limed.
3. The switch on the control panel labelled MANUAL
and the switch labelled WASH should be used
when de-liming the machine. When activated,
these switches keep the machine in an indenite
wash cycle. This feature can also be used to wash
heavily soiled ware.
NOTE:
The water quality in some areas
requires de-liming to be done more
frequently. Contact your detergent
supplier for recommended de-liming
frequency.

CAUTION:
Do not remove wash and rinse spray arms from the
hubs as these are factory set. Cleaning should be
done by removing the endcap on each arm.

Tank Heat Temperature Adjustment
A temperature control board is provided in the control
panel for easy adjustment of tank temperature.
Though tank temperature is set during factory testing
it is sometimes necessary to re-adjust the temperature
at start-up.
1. Locate the temperature control board (P/N DE9-
251). Use the control panel layout drawing located
in PART 7, Electrical Schematics and Parts.
2. Adjust the tank temperature to the correct
temperature by turning the potentiometer located
on the temperature control board. An arrow on the
potentiometer indicates increase.
Troubleshooting Tank Temperatures
If the temperature does not change follow the below
procedures.
Electric Heat:
1. Check the temperature control board (P/N DE9-
251) for proper operation. If the temperature
control board is faulty, replace.
2. Verify tank heat contactor is working correctly. If
not, replace.
3. Verify all immersion heaters are working properly
and are not limed. If not, replace.
Steam Heat:
1. Check the temperature control board (P/N DE9-
251) for proper operation. If the temperature
control board is faulty, replace.
2. Verify steam pressure per machine specications.
3. Verify steam trap is not clogged. If so, clean and/or
replace.
Immersion Heater Replacement (SK-4703)
1. The immersion heater MUST be completely
submerged at all times. If this is not the case
contact a qualied service technician. The heated
surface should never be in contact with sludge.
2. Remove the housing covering the wiring
terminations. Disconnect the immersion heater
wires.
3. Remove the immersion heater by loosening and
removing the large hex nut.
4. Install in reverse of removal.

Level System
The level control system consists of one level timer
(P/N DE7-35) and one level oat (DE5-60) per tank.
When the system is powered-up, the tank(s) will
begin to ll (assuming no water is in the tanks).
Once the level oat is actuated, the timer begins to
time-out and continues the lling process until the
tank(s) is full.
Should the tank heat energize without water in the
tank troubleshoot the system to nd the problem
CAUTION:
Dirty level oats will cause the tank heat to energize
with no water in the tanks. Level oats MUST be
cleaned daily.
Motor Overloads
All motors used on Insinger Machines are provided
with motor overloads. Motor overloads are adjusted
when the machines are factory tested. Should it be
necessary to adjust the motor overloads in the eld
rst verify the motor current draw for the voltage the
machine is using.
Refer to the Control Panel Layout drawing located in
PART 7 to identify the overload, adjust by turning the
dial to the appropriate AMP draw.
