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!

With 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).

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).

With 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).

Turn the On/Off/Fill Switch to the Fill position and release it. At this point the machine will

start to fill. If it doesn't fill to the overflow, reprogramming of the auto fill may be necessary

(refer to Programming the 1827 Board). You must also make sure the incoming water

pressure is in-between 20psi to 30psi flow pressure as stated in the Recommend Installation

Guide. Note: incoming water pressure over 30 psi will void warranty to related items.

Select 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).

Now its time to fill 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 filled,

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.

Now it's time to set the thermostats. We're 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
