Remove and clean package pre–filter, replace if needed

Check the cooler(s) for build up of foreign matter. Clean if necessary by blowing out with air or by pressure washing.

1. Stop the machine, electrically isolate and vent all trapped pressure.

2. Remove the top cover to obtain access to the cooler.

Check hoses and fittings for leaks – tighten as required.

Change drive belt and gas spring.

Replace the Ultra Coolant at whichever interval occurs first.

It is better to drain the coolant immediately after the compressor has been operating as the liquid will drain more easily and any contaminant will still be in suspension.

1. Stop the machine, electrically isolate and vent all trapped pressure.

2. Place a suitable container close to the drain valve.

3. Slowly remove fill/vent cap.

4. Remove plug from drain valve.

5. Open the drain valve and drain coolant into container.

WARNING: The dryer’s refrigeration system operates in a pressurised shutdown mode. If the compressor stops, the system will contain high pressure refrigerant. The refrigeration system must only be opened by a qualified technician certified in handling refrigerants. Never adjust thermal expansion valve. It has been factory set.
