SECTION 3: OPERATION
Oil Skimmer
The oil skimmer is located on the right rear corner of the
machine (See Figure Below). It automatically removes
oil from the wash solution to prolong its useful life. Re-
fer to Using the Oil Skimmer for detailed operating
instructions.
Water Level
Under typical operating conditions the machine loses
3 to 5 gallons of water per day to evaporation.
It is important that you monitor and maintain the water
level daily to minimize the risk of burning out the heating
element or ruining the pump.
NOTE: Water evaporates from the sump chamber,
but the detergent does not. It is not necessary to add
detergent each time you add water. Only add deter-
gent after you clean the sump chamber each month,
or if you notice specific low-detergent indicators
(See Detergents and Additives).
Automatic Water Fill (Optional)
The optional automatic water fill system automatically
maintains a proper water level in the sump.
The automatic water fill system uses the low water
shut-off proximity switches to open and close a water
solenoid valve, which automatically maintains a proper
water level in the sump. The figure below describes the
operation of the automatic water fill system.
Low Water Shut-off
The low water shut-off system shuts down the machine
if the wash solution in the sump chamber drops below a
safe level. The system uses two proximity switches and
a float rod mounted near the rear of the sump chamber
to monitor the water level.
If the wash solution drops below the lower proximity
switch, the low water indicator light on the control panel
turns on and the system disconnects power to machine.
To reset the system, add water to the sump until the
low water indicator light turns off.
