of adjustment will damage the pneumatic assembly.

To connect an air supply

1. Use a 5 mm hex wrench to turn the pressure adjustment screw
counterclockwise until it stops (off).
See Figure 3‐7.
2. Insert the male fitting located on the outlet side of the air filter
(P/N 1023267) into the air inlet port on the back of the melter.
CAUTION! Rigidly support the plant air supply before connecting it to the air
filter.
3. Connect a regulated plant air supply to the inlet of the air filter. If required,

NOTE: The air filter inlet is threaded to receive a male G1/4 BSPP fitting.
4. Open the plant air supply to the melter.
5. Turn the pressure regulator adjustment clockwise to set the melter's
operating air pressure (pressure supplied to the pump) to
1.4 Bar (20 psi). The operating air pressure should be adjusted later to
meet the requirements of the manufacturing process.
NOTE: The minimum operating air pressure is 0.7 bar (10 psi). Operating
the melter with the air pressure set to less than 0.7 bar (10 psi) may cause
the pump to function erratically.
