such that they do not touch printed circuits on PCBs.
Observe when Using Residual Current Circuit Breakers
Local regulations in some industrial branches require residual current circuit
breakers.
S
Use permanent, fixed line voltage connections.
S
Install the residual current circuit breaker between the power supply and
the bulk melter.
S
Use residual current circuit breakers sensitive to pulsating current or
universal current (> 30 mA).
Laying Cable
WARNING! Use only temperature resistant cable in the heating part of the
bulk melter. Make sure cables do not touch rotating and/or hot parts. Do not
pinch cables and check regularly for damage. Replace damaged cables
immediately!
Power Supply
WARNING! Operate only at the operating voltage shown on the ID plate.
Permitted deviation from the rated line voltage is ¦10%.
CAUTION:
S
The power cable cross-section must comply with the rated current (Refer
to ID plate)

Connecting
If cold material can be found in the hose connection (1), the components
(2, 3) must be heated until the material softens (approx. 70 _C / 158 _F,
depending on material).
1. First connect the hose (3) electrically to the unit.
2. Heat the bulk melter and hose to approx. 70 _C / 158 _F.
3. Secure the hose to the unit.
NOTE: Close unused hose ports with Nordson port plugs.
Disconnecting
WARNING: To prevent serious burns, You MUST relieve the melter
pressure before disconnecting pressurized components, such as hoses, and
applicators/handguns.
Relieving pressure
1. Switch the pump Off.
2. Set selector Raise/lower platen to 0/stop.
3. Place a container under the nozzle(s) of the applicator or handgun
assembly.
4. Applicators/handguns: Activate the solenoid valve(s) electrically or
manually; or, pull the trigger on the handgun. Repeat this procedure until
no more material flows out.
5. Properly dispose of material according to local regulations.
Connecting Assembly Handguns
Connect the assembly handgun switches to receptacles Hose/Applicator 1
and Hose/Applicator 2.
When the assembly handgun is triggered (switch closed), the pump is
switched on.
