MACHINE OPERATION RECOMMENDED MAINTENANCE
1. Inspect pump, electrical cord and plug.
Do not use machine if any wear or damage is noticed until
impaired components are repaired or replaced.
Be sure electrical cord is unplugged and cleaning solution
and heater coil is cool before performing any
maintenance.
1. To maximize cleaning efficiency, fluid should be changed
regularly. Heavy, constant use may warrant daily fluid
changes.
2. Check cleaning solution level and add if necessary.
3. Press TEST button on GFCI to ensure switch is operating
properly. Press RESET button on GFCI to prepare unit for
operation.
2. Inspect heater coil on a monthly basis. To inspect,
remove baffle screen. Remove any deposits or buildup
with a soft wire brush.
Deposits and buildup can cause premature failure of the
heating coil.
4. Toggle POWER switch
located on the underside of
the electrical box to the ON
position. The red “RESET”
light will illuminate.
5. Toggle RESET switch located
under the electrical box to
begin operation. The green
“READY” light will illuminate
and the red “RESET” light will
extinguish.
6. Turn thermostat to desired
operating temperature. If
heat is required you should
hear the thermostat engage
with a “CLICK” and the amber
“HEAT” light will illuminate. Should this not happen, press
the red reset button above the thermostat. Should you
wish to run the unit unheated, rotate the thermostat dial
counterclockwise until it stops. For best results, allow
cleaning fluid to reach desired temperature before
operation.
Operator Interface
3. Filter cartridge will require periodic replacement depending
upon the volume and types of soils involved. A significant
reduction in the flow through the flexible hose signals the
need to replace the filter cartridge.
Save this manual for future training. Do not allow
operation without reading and understanding these
instructions.
7. To operate the fluid pump, toggle PUMP switch on front of
electrical box to the “ON” position.
8. For fluid via the flexible hose turn the directional valve
counterclockwise to the left.
9. For fluid via the flow-thru brush turn the directional valve
clockwise to the right.
10. Turn heater and pump off when unit is to be idle for
extended periods (overnight and weekends). This will
minimize liquid loss due to evaporation as well as reduce
operating costs.
ADDING FLUID TO UNIT
Follow instructions and exercise
appropriate safety precautions
before adding fluid.
Max-Fill Slots
1. Turn machine off and unplug.
2. Open lid and remove stainless
steel shelf.
3. Add properly diluted cleaning
solution to top of max-fill slots
(right).
4. Reinstall shelf, restore power
and resume normal operation.
