NEVER place any towel or obstruction over the fan intake on cover. The air
temperature during Hot Air Drying can be increased or decreased by adjusting two
thermo-switches located in cover at hot air exit. The thermo-switches are adjusted
as shown below.
1. Disconnect unit from 120VAC and 230VAC supplies.
2. Remove top plate of dryer cover.
3. Thermostat is located in front of heater.
4. See drawing 1. Turn control knob slightly counter-clockwise to
decrease temperature.
5. Replace top plate and check air temperature. Repeat steps 1-4 if
not satisfactory.
Maintenance
1. Filters-Periodically the filter cartridges need to be changed as describe in a
previous section.
2. Drain Screens-Y strainers are located in the drain and overflow lines.
Periodically the drain screen in these strainers located under the tank inside the
unit will have to be removed and cleaned. Accumulated lint and debris could
slow down the draining, resulting in the incomplete removal of cleaning
solution before the rinse cycle starts.
The tank and modules are manufactured of 316 and 304 stainless steel. Clean with
a commercially available cleaner for stainless kitchen appliances.
Power Modules
The power modules contain the circuit boards, programmable controller, fans,
relays, RFI filters etc. There are 6 lights, one per circuit board to indicate if circuit
boards are operating. To check if all circuit boards are operating, open door
slightly when unit is ultrasonically cleaning; all indicator lights must be ON. If a
light is out, the corresponding circuit board will have to be repaired.
