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 cylinder 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 air flow 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).
The air flow 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 air flow switch. To adjust the air
flow switch refer to appropriate paragraph in Section IV.
The tumbler must not be operated if the air
flow switch does not operate properly.
Faulty air flow switch operation may cause
an explosive gas mixture to collect in the
tumbler.
