Operations
Water Level
Under typical operating conditions the machine loses 3-
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 necessary to add
detergent each time you add water. Only add
detergent after you clean the sump chamber each
month, or if you notice specific low-detergent
indicators (See
Detergent Concentration
).

Automatic Water Fill (Optional)
The automatic water fill system automatically maintains
a proper water level in the sump. It is available as an
option on this machine.
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 figures below demonstrate
the operation of the automatic water fill system.
