PRELIMINARY OPERATING CHECKS

1.Remove or open all panels and check accessible bolts, nuts, screws, terminals and fittings for tightness.

2.Check V-belt tension and adjust if necessary. Refer to appropriate paragraphs in Section IV.

3.Steam tumblers: Open the steam service shut-off valves.

4.After performing the previous checks, start the tumbler by pressing START (hold for approximately three seconds). Release the start button and open the cylinder door. The cylinder should stop rotating within seven seconds after the door is opened a maximum of two inches (5.01 cm) plus or minus ¹⁄₄ inch (.63 cm). If it does not, adjust the loading door interlock. Refer to the appropriate paragraph in Section IV.

5.Gas tumblers: Start the tumbler and check the burner flame. Adjust the gas inlet shutter as required. Refer to the appropriate paragraph in Section IV.

IMPORTANT: The one wire igniter Instant Electronic Ignition system will attempt to light the gas by sparking for approximately 15 seconds (5 seconds for 2 wire igniters). If gas ignition does not take place within 15 seconds (5 seconds for 2 wire igniters) the Instant Electronic Ignition control will go into safety lockout and the valve will no longer open until Instant Electronic Ignition control is reset. To reset Instant Electronic Ignition control, remove power from control by opening and closing the tumbler door. If condition persists, check, that the gas shut-off valve is in “on” position and that the gas service is properly connected. If condition still persists, remove tumbler from service.

6.Load the cylinder with a full load of clothes or clean rags and run to remove oil or dirt from cylinder.

7.Gas and electric tumblers: Check the airflow switch operation by opening the lint panel. The heating systems should shut off when the lint panel is opened a maximum of 1-1/2 inches (3.81 cm).

WARNING

The tumbler must not be operated if the airflow switch does not operate properly. Faulty airflow switch operation may cause an explosive gas mixture to collect in the tumbler.

W072

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 appropriate paragraph in Section IV.
