Nordson Bulk Melter 7407666

Warning: Drain lubricant when warm. Use only the stated lubricant or one that has proven to be equivalent. Using any other lubricant can result in premature wear and/or damage to the gear box. Properly dispose of the old lubricant according to local regulations.

Gear box removed from the motor?

Casing washed with suitable cleaning agent and lubricant residue removed?

Lubricant Changing Interval: When lubricant temperature is below 100° C / 212° F: Every 15000 hours of operation or at least every 2 to 3 years.

Enter the lubricant temperature

The lubricant quantity is indicated on the ID plate.

NOTE: Never mix different types of lubricants.

WARNING: Hot! Risk of burns. Wear heat-protective gloves.

WARNING: Risk of electrical shock. Failure to observe may result in personal injury, death, or equipment damage.

1. Disconnect the bulk melter from the line voltage.

1. Apply heat transfer compound (Refer to page 8-2, Processing Materials) to the new thermostat and replace.

1. Carefully pull the temperature sensor out of the melting plate by the connecting cable. If it cannot be pulled out easily, the melting plate must be removed. Refer to page 10-5, Replacing Melting Plate.

WARNING: System and material pressurized. Relieve bulk melter pressure before disconnecting pressurized components (e.g. hoses, pressure sensors). Failure to observe can result in serious burns. Refer to page 10-1, Relieving Pressure.

WARNING: Hot! Risk of burns. Wear heat-protective gloves.

NOTE: Detach the gear pump only when the material is soft (approx. 70 ° C/158 ° F, depending on material).

1. Remove the cover and detach the Cardan joint (1) from the pump shaft.

3. Allow the bulk melter to cool to room temperature.

1. Clean the sealing surfaces on the plate and pump. If necessary, heat material residue with a hot air fan, then remove.

Place a container of cleaning agent in the bulk melter to purge. Then feed the cleaning agent until it comes out free of material residue.

CAUTION: Use only a cleaning agent recommended by the hot melt material manufacturer. Observe the Material Safety Data Sheet for the cleaning agent.

Before starting production again, flush out residue of the cleaning agent using the new material.

NOTE: Properly dispose of cleaning agent according to local regulations.;

WARNING! For safety reasons, the safety valve may not be disassembled. The complete valve must be replaced every time.

WARNING: System and material pressurized. Relieve bulk melter pressure before disconnecting pressurized components (e.g. hoses, pressure sensors). Failure to observe can result in serious burns. Refer to page 10-1, Relieving Pressure.

WARNING: Hot! Risk of burns. Wear heat-protective gloves.

Observe when replacing: Replace the valve only when the bulk melter is heated. Otherwise the sealing rings could be damaged by charred material

Apply high temperature grease to all threads and O-rings (Refer to page 8-2, Processing Materials)
