SECTION 3: OPERATION
Low Water Shut-off System
The low water shut-off system shuts down the ma-
chine if the wash solution in the sump chamber drops
below a safe level. The system uses two reed switches
and a float rod mounted on the right outer wall of the
sump chamber to control the water level (See Figure
Below).
If the wash solution drops below the lower reed switch,
the low water indicator light on the control panel turns
on and the system disconnects power to the heating
element, the pump, and the turntable motor. To reset
the system, add water to the sump until the low water
indicator light turns off.
WATER LEVEL OK:
Both switches OPEN, Automatic
Water Fill Valve (if installed)
CLOSED, Heating Element ON.
LOW WATER LEVEL:
Top switch CLOSED, Bottom Switch
CLOSED, Automatic Water Fill Valve (if
installed) OPEN, Heating Element OFF.
SUMP FILLING:
Top switch CLOSED, Bottom Switch
OPEN, Automatic Water Fill Valve (if
installed) OPEN, Heating Element OFF.
Automatic Water Fill (Optional)
The automatic water fill system automatically maintains
a proper water level in the sump. It is available as on
option on these machines.
The automatic water fill system uses the low water shut-
off reed switches to open and close a water solenoid
valve, which automatically maintains a proper water
level in the sump. The figure above describes the opera-
tion of the automatic water fill system.
DETERGENTS AND
ADDITIVES
Detergents
Manufacturer's detergents are the only detergents
approved for use with our Automatic Parts washers.
They are specially formulated with rust inhibitors and
anti-foaming agents to optimize performance and
minimize maintenance. The use of any other detergent
during the warranty period will void the warranty.
To monitor the relative concentration of the detergent
in the wash solution, periodically examine the wash
solution in the sump chamber for the following
indicators:
• Rust inside the machine: not enough
detergent
• Excessive foaming: not enough detergent
• Thick, white residue on parts after
washing: too much detergent
To maintain proper detergent concentration under
typical operating conditions, add detergent each month
