For Polyjet parts select the ‘HEAT OFF’ option.
Connect the power cord to the side of the unit then to a suitable grounded wall socket.
The unit is compatible with both North America 110V~50/60Hz and International
220V~50/60HZ power. The unit ships with both power cords. Only use a power cord
provided by the manufacturer.
It is strongly recommended that the unit be placed on a circuit with its own breaker with a
GFCI. The power circuit must be grounded.
Press the ON/OFF rocker switch. The display control panel should be on.
Press one of the four temperature preset buttons or the Heat Off button to select the cleaning
temperature. The temperature can be changed at any time during the cycle by selecting a
different temperature button. If heating the water from room temperature to 70°C, it takes
about 2 hours to reach temperature.
Press the SET button and then press the up and down arrows to set the minutes. Press the
SET button again and use the up and down arrows to set the hours. Press the SET button
again to accept the time. Press the
button to start the heater and pump.
8.4: Loading Parts and Testing Level Sensors
Wait until the SCA has reached the desired temperature before loading parts into the tank.
This minimizes the time the parts are immersed in the cleaning solution.
Open the lid on the large parts basket and place the parts inside.
For smaller parts, open the spring-latched door of the smaller, square basket, place the
part(s) inside and place small basket inside larger basket.
Before placing the basket into the cleaning solution, press the
button to pause the
heater and pump. With the basket cutout facing the nozzle, slowly lower the large parts
basket into the solution-filled tank. The spray nozzle should be centered on the basket
cutout.
If the high level alert lights and the alarm sounds, press the
button to silence the
alarm, and remove liquid by draining or scooping liquid from the tank until the alert
indicator is no longer lit.
Note: It is recommended that the level sensors be tested periodically. Adding water to
just above the MAX fill line should cause the high level alert to illuminate and the buzzer
to sound. Draining water until the liquid level is below the MIN fill line should cause the
