Compressed air connection
Connect the compressed air supply (quick coupler PK4) to the connection (1)
(see Figure 2).
The supplied compressed air must be free from condensate and oil.

Heatable hose
Required tools
• 1 open-end wrench size 14
• 1 open-end wrench size 19 (Pt 100) or
• 1 open-end wrench size 18 (Ni 100)
To connect the heatable hose, carry out the following steps:
1. At the tank system, activate the heater of the corresponding output.
2. Switch off the pump.
3. Allow the heatable hose to heat to operating temperature.
4. Screw on the heatable hose with connection (5)
(see “Figure 2: Connections HB 11”
on page 6) .
While doing so, secure the application head with the open-end wrench size 14.
The application head can now be put into operation.

Operation
4.1
Initial operation
The heating time of the application head is significantly less than those of the other com-
ponents (tank system/heatable hose).
After the tank system has heated, the application head can be put into operation immedi-
ately. Additional preparations are not necessary.
4.2
Adjusting the adhesive dosage
The adhesive discharge per timing cycle depends on the parameters
• Adhesive pressure
• Nominal diameter of the nozzle
• Opening time of the solenoid valve
After initial operation, use trials to determine the optimal combination of these parameters
for your application.
4.3
Interruptions in work/End of shift
In case of longer periods of interrupted work/end of shift, the application head can be put
out of operation by switching off the heater.
When switched back on, the heating time of the heater is less than 10 minutes.
4.4
Processing PU hot melt adhesives
For PU (polyurethane) adhesives, the humidity triggers a chemical reaction which leads to
the firm bonding of the objects to be glued.
