Connections
Connect the overflow of freshwater rinse (PVC Spout D30/22) with your rinse water treatment. Make a
connection to the fresh water inlet (Thread 3/4”). If you use a closed-loop rinsing tank, connect this tank as
well. If there: Connect the exhaust tube (D62/50) to your room ventilation.
Control
Before connecting the machine to the power supply, please check:
The conveyor belt must run parallel to the side walls of the machine. All upper rollers must lay close on the
lower ones.
If the cover has been taken off the machine, the intermediate walls and the cover must be remounted.
Take care to mount the cover in a way that it sits well all on the machine body and that the security switch
is closed.
Check if all fittings are well attached and if all appropriate valves are closed. If necessary, tighten the fit -
tings manually.
With respect to the built-in stoppers, move the control unit to the desired position.
Electrical connection
Switch off all the switches on the front panel. Turn the adjustment knobs of the conveyor belt and the
thermostat to zero position. Connect the power plug to a splash water-protected wall socket. The ma-
chine's power consumption (with the heater running) is about 1.9 kW on 220 V, 50 Hz. We assume that
an appropriate fuse has been installed to the in-house power circuit.
Now turn on the main switch. It will be lit.
First Filling
As a check for tightness and function you should operate the machine first only with water. After success-
ful test run the water is replaced by etching agents. If the medium container was demounted for transport,
put it back into its position, bolt the connections of the two gutter-pipes and the tubing and connect the
plug contacts for thermostat, heating staff and engine (plug are permutation implemented). You can give
the water through the opening in the cover (filling height is approx. 1 cm under cover of the medium con-
tainer).
Test Run
Referring to the description in chapter Operating, check the function of
conveyor
heater pump
rinse.
Pay special attention to the following topics:
Conveyor
The belt and the rollers must move in a steady and uniform way. At position 1 on the scale, the conveyor
must just transport a board through the machine.
Pump
When running the pump, have a close look on the fittings and the cover. No leaking should be obvious.
There are two ball valves in the mounting tubes fed by the pump. These valves can be used to reduce
spray pressure, if necessary. A very low pressure also permits to see if all nozzles are operating and spray
in the right direction. See chapter
Cleaning and Maintenance
for details on how to adjust the manifolds.
Heater
In the first test run, it is not necessary to wait for the water to heat up
completely. The thermostat is adjusted during the final inspection at the
factory. It is therefore sufficient to check the control behavior at any tem-
perature setting by adjusting the set value just above or below the dis-
played actual value and control if the LED turns on (machine is heating)
or turns off (heater is switched off). You can change the set temperature
by pressing SET tow times at the thermostat display and then adjust Set-
temperature with the arrow buttons. Press again SET -. the display shows the word "set" and will return
after a few seconds to the actual temperature).
If you open the cover of the hand hole of the medium container the Quartz heater visible. In the heating
phase, the switch will light up at the control panel and the heating element takes a orange-red color.
