Raising Heating Punch
If the heating punch is inside of the drum, the drum must be aerated to
support raising. Aerating means that compressed air is forced under the
heating punch.
1. Aeration must be done manually for models without automatic aeration
valve:
a. Screw out rod (1).
b. In place of the rod, screw in the aeration pipe (2, stored in the holder
on the electrical cabinet).
c. Attach aeration connection (3, stored on the cross beam) to aeration
pipe.
2. Set pneumatic switch to Raise.
Automatic drum aeration begins when the pneumatic switch is moved to
Raise and ceases when the punch leaves the drum. In case the heating
punch lifts the drum:
S Quick fix: Set pneumatic switch to 0 and press two‐hand control to
increase air pressure in drum.
S Long term solution: Reduce heating punch lifting speed (Refer to
Installation).
The air pressure in the drum is limited to 1 bar (0.1 MPA / 14.5 psi) by a
pressure restrictor valve.
Lowering Heating Punch
The drum must always be deaerated when the heating punch is moved into
the drum. When the drum is deaerated, the air that is under the heating
punch escapes.
1. Set pneumatic switch to Lower.
2. Place the drip pan (3) in front of the deaearation valve (2).
3. Open deaeration valve on lever (1).
4. Press both buttons on the two‐hand control at the same time
(within 0.5 seconds) until the heating punch is inside of the drum.
The downward movement continues on its own.
5. Close deaeration valve when material flows out free of bubbles.
6. Properly dispose of material according to local regulations.
