START UP
IMPORTANT: LOCATE AND REMEMBER WHERE YOU’RE ELECTRICAL DISCONNECTS ARE.
Some of the following steps will be performed in the electrical panel enclosure. We recommend disconnection
of all incoming power before doing any service in the electrical enclosure. Please Be Cautious!
6With incoming electrical power disconnected or turned off, remove electrical panel enclosure cover.
Turn all thermostats to the lowest or off position (turning knobs in the counter clockwise direction).
6 Locate and make sure the drain and pump petcock is in the closed position. The pump petcock will
remain in the closed position from now on unless service is needed on the pump. Shut off all breakers
going to the heaters if electrically heated (breakers will be marked WASH HEATER, RINSE HEATER).
6From inside the machine’s wash tank below the lter baskets, locate the oat switch and remove
the zip tie that was used for shipping. The oat will have a tag attached to it with (REMOVE ZIP TIE
BEFORE START UP).
6With electrical enclosure panel cover still off, turn incoming power back on. Make sure the circuit
breaker marked PUMP and breaker marked 120 is in the on position. APPLIES TO U.S. MODELS ONLY
(BE VERY CAUTIOUS THIS IS NOW A HOT PANEL).
6Turn the On/Off/Fill Switch to the Fill position and release it. At this point the machine will start to
ll. If it doesn’t ll to the overow, reprogramming of the auto ll may be necessary. You must also
make sure the incoming water pressure is in-between 20psi to 30psi ow pressure as stated in the
Recommend Installation Guide. Note: incoming water pressure over 30psi will void warranty to related
items.
6Select the Short Wash Cycle and push the Start Button, the wash pump should start running at this
point. If pump doesn’t start running, check that all fuses are in (if applicable) and all breakers marked
PUMP and 120 are in the on position. With pump running, check pump rotation, looking at the rear
of the pump motor, the fan should be rotating in a clockwise direction. If pump is not rotating in the
correct direction reversal of electrical phases will be necessary (contact your electrician or Douglas
Machines for details).
6Now its time to ll the rinse tank. Depress the Start button, the machine will now run through a
complete cycle. A complete cycle entails, wash (pump running), rinse (pump not running, rinse solenoid
valve open), and a one- (1) minute dwell & steam extraction (during dwell the machine can not be
restarted). Please note while the machine is in the rinse and dwell period you will not see any readings
on the jet pressure gauge. To ensure the rinse tank is lled, you need to physically hear water spraying
inside the wash cabinet after the wash pump has stopped running. You may need to run more than
one –(1) cycle to accomplish this. CAUTION: Before proceeding to the next step, make sure you can
hear water spraying in the cabinet after the wash pump stops running. If not heater damage may
occur, warranty will be void to related items.
6Now it’s time to set the thermostats. Were looking for a reading on the temperature gauges to be 150
degrees wash temperature and 190 degrees rinse temperature. Turning the thermostat knobs in a
clockwise motion, and using top dead center as our indicator, increase the thermostat marked WASH
to 150 degrees, now increase the thermostat marked RINSE to 190 degrees. Allow 30 to 60 minutes
for heat up time. Note: There can be as much as 12 to 15 degrees various between the thermostat and
the temperature gauge. Always set the thermostats to accommodate the desired temperature gauge
reading.
