DOUGLAS MACHINES CORP. LD-20-PT Panduan Pengoperasian
To ensure the rinse tank is filled, you need to hear water spraying inside
the wash cabinet after the wash pump has stopped running. You may
need to run more than one 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 and the
rinse light cycle is illuminated. If not, heater damage may occur and
the warranty will become void for related items.
8. Now it is time to set the thermostats. We are 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 difference between the
thermostat and the temperature gauge. Always set the thermostats to
accommodate the desired temperature gauge reading.
9. At this point your heat source should be engaged. If electrically heated, the
wash and rinse heater contactors will be engaged. If gas heated, the
burner or burners will fire. If steam heated, the steam solenoids will open.
If you are not sure, or if the specific heat source is not on and the unit is
not heating up, contact Douglas Machines for assistance.
10. Now that everything is working fine. It is time to put the electrical enclosure
panel and front panel back on the machine and start washing.
