Maintenance & Troubleshooting Manual
1)
Fill the reservoir with tap water
–
don’t
reach the inlet port level (you could spill it into LIVE
ELECTRICAL DEVICES LATER ON)
2)
Turn on machine
–
pump will work in the opposite way it was working (possibly removing any
obstruction into pipes) If there is no water flow, chances are that extruder holder block is jammed.
Take the following extra steps:
a.
drain all the liquid from the cooling circuit
b.
remove all extruders from the machine
c.
unplug machine from AC power
d.
pull and detach piping entering the extruder block
e.
use compressed air to blow inside both entry points into extruder holder block
f.
when air is freely flowing in BOTH ports, re-connect piping to the extruder block and restart
from #6 (fill reservoir)
g.
Keep adding water to the tank to the tank to get complete pipe cleaning
3)
If water is still not flowing, turn power off
–
turn power on and:
a.
Check all piping that no sharp bends are obstructing flow
b.
Check that no pipe is being pinched by metal panels
–
remove all relevant panels to check
piping
c.
Check that pipes into extruder holder assembly are not bent into connector area
d.
When water flow is steady (and works even when pump is powered off) let the circuit to
completely drain
e.
Using DEMINERALIZED PURE WATER (same grade used for batteries) ll again the circuit and
add until circuit is completely clean from any tap water residual
f.
Let the circuit to completely drain
g.
Turn power off and detach power cord
h.
Restore original piping condition (inlet and outlet connections)
i.
Fill system with de-mineralized water. Turn machine on
4)
Tapping on inlet port, remove any air bubble trapped into heat exchanger
–
you must feel subtle
pressure on inlet port flow entering the reservoir
5)
Be sure that water level is OK
NOTE
- Using pure de-mineralized water is approved alternative to factory supplied blue tinted
liquid.
