SECTION 3: OPERATION
MAIN OPERATING
COMPONENTS
Familiarize yourself with the main operating compo-
nents before operating the machine.
CONTROL PANEL
Heater Control
The heater control is a 12-hour timer switch. It con-
trols the heating element in the sump chamber. The
heating system is thermostatically set at the factory to
reach a high temperature of 180°F. The temperature is
adjustable using the thermostat (See Adjusting the
Thermostat).
Wash Cycle Control
The wash cycle control is a 60-minute timer switch with
a hold feature. When set between 1 and 60 minutes,
the timer automatically shuts off the pump and turntable
when the wash cycle is complete. When set to Hold,
the pump and turntable run continuously until manu-
ally shut off.
Skimmer Control
The skimmer control is a 30-minute timer switch. It
controls the automatic oil skimmer.
Turntable Switch
The turntable switch is a simple rocker switch that en-
ables you to disconnect power to the turntable motor.
Set to ON, the turntable rotates during the wash cycle.
Set to OFF, the turntable does not rotate during the
wash cycle. The switch is useful for washing large parts
that would otherwise impede turntable rotation.
Low Water Indicator
The low water indicator light illuminates if the wash
solution in the sump is low. For more information refer
to Low Water Shut-off.
24-hour, 7-day Timers
Models 2840, 2840, and 2848 machines are available
with a 24-hour, 7-day heater timer or a 24-hour, 7-day
heater and oil skimmer timer. The heater timer controls
the heating system. The heater and oil skimmer timer
controls the heating system and the oil skimmer.
The timer is located below the electrical panel inside the
main electrical enclosure. To configure the timer, refer
to the instruction label inside the timer door.
Thermostat
The thermostat is located inside the heating element
and thermostat enclosure. Single phase thermostats
have an adjustment screw that is accessible only from
inside the enclosure. Three phase thermostats have
an adjustment knob mounted on the outside of the
enclosure.
The thermostat is factory-set to heat the wash solution
to a maximum temperature of 180°F.
Adjusting the Thermostat
To adjust the thermostat, rotate the adjustment screw
or knob clockwise to increase the temperature, or
counter-clockwise to decrease the temperature (See
Figure Below).
