Before Placing Tumbler into Service

1. Remove or open all panels and check accessible

bolts, nuts, screws, terminals and fittings for
tightness.

2. Check belt tension and adjust if necessary. Refer

to Adjustments section.

3. Replace all panels and guards.

4. Turn on electrical supply to tumbler.

5. Open the supply valve for gas or steam heated

tumblers.

6. After performing the previous checks, start the

tumbler by pressing START. (Refer to the
Operating Manual for detailed instructions.)
Release the start button and open the loading
door. The cylinder should stop rotating within
seven seconds after the door is opened a
maximum of 2 inches (51 mm). If it does not,
adjust the loading door switch. Refer to
Adjustments section.

7. Gas Tumblers: Start the tumbler and check the

burner flame. Adjust the air inlet shutter as
required. Refer to Adjustments section.

IMPORTANT: The electronic ignition system will
attempt to light the gas by sparking for the “trial
for ignition” period. If gas does not ignite within
this period, the ignition control will go into a safety
lockout and the valve will no longer open until the
control is reset. It may be necessary to retry several
times to bleed air from the gas lines. To reset, open
and close the loading door and restart tumbler.

If lockout condition persists, check that the manual
gas shut-off valve is in the ON position and that the
gas service is properly connected. If condition still
persists, remove tumbler from service.

8. Load the cylinder with a full load of clean rags

and run to remove oil or dirt from cylinder.

9. Check the airflow switch operation refer to

Adjustments section. The heating systems should
shut off when the lint panel is opened a
maximum of 1.5 inches (38 mm).

The airflow switch operation may be affected by
shipping tape still in place, lack of make-up air,
or an obstruction in the exhaust duct. These
should be checked and the required corrective
action taken before attempting to adjust the
airflow switch. To adjust the airflow switch, refer
to Adjustments section.

10. Wipe out the cylinder using an all-purpose

cleaner or detergent and water solution. Refer to
Figure 10.
