Replacing The Tank Thermostat - Nordson ProBlue 1028303 Instruction Sheet

Replacing the Tank Thermostat

1.
To replace the tank thermostat you must first remove the pump.
If the temperature of the tank is below 120 °C (250 °F) it may not be
possible to remove the pump until the melter is reheated.
To reheat the melter:
a. While pressing both the Setup and the Tank
key, cycle the control switch off and then on
again. The left display will flash to indicate that
the melter is heating in the override mode. The
melter will continue to reheat for 20 minutes and
then automatically switch off.
b. To continue reheating the melter, repeat step a.
until the melter reaches 120 °C (250 °F).
4.
Remove the pump as follows:
a. Rotate the isolation valve handle upward
until it is vertical.
2.
Switch the melter off.
b. Remove the three pump-mounting bolts.
3.
Relieve system hydraulic pressure. Refer to the
melter manual for information on relieving hydraulic
pressure.
c. While pulling the pump away from the
manifold, tilt the top of the pump toward the
front of the melter and then remove the air line
from the back of the pump.
Note:
The face of the pump body contains two
M6 threaded holes. Bolts can be threaded into
these holes to gain leverage when removing the
pump.
d. Lift the pump clear of the melter.
