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

Min 3 bar 0.3 MPa 43.5 psi
Max 8 bar 0.8 MPa 116 psi
NOTE: A pressure restrictor valve behind the compressed air connection
limits the air pressure to 8 bar / 0.8 MPa / 116 psi
Pneumatic Plate
Also refer to pneumatics diagram.
Pressure Control Valves
CAUTION: Do not change the setting:
S
Raise pneumatic cylinder (2).
NOTE: Default pressure is 1.6 Bar / 0.16 Mpa / 23.2 PSI
S
Aerate container (3):
NOTES:
S
Default pressure is 1 Bar / 0.1 Mpa / 14.5 PSI
S
A lower pressure makes it difficult to raise the platen.
