H. PREPARATION FOR OPERATION
The following items should be checked before attempting to operate the dryer:
1. Read ALL “ CAUTION ,” “ WARNING ,” and “ DIRECTION ” labels attached to the dryer.
2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label. In case of
208 VAC or 230 VAC, the supply voltage must match the electric service exactly .
3. Check to ensure that the dryer is connected to the type of heat/gas indicated on the dryer data label.
4. The sail switch damper assembly was installed and adjusted at the factory prior to shipping. However,
each sail switch adjustment must be checked to ensure that this important safety control is functioning.
5. Be sure that ALL gas shutoff valves are in the open position.
6. Be sure ALL back panels (guards) and electric box covers have been replaced.
7. Check ALL service doors to ensure that they are closed and secured in place.
8. Be sure lint drawer is securely in place.
NOTE: LINT DRAWER MUST BE ALL THE WAY IN PLACE TO ACTIVATE SAFETY
SWITCH OTHERWISE THE DRYER WILL NOT START .
9. Rotate the tumbler by hand to be sure it moves freely.
10. Check bolts, nuts, screws, terminals, and fittings for security.
11. Check to ensure air supply (80 psi [5.51 bar]) is connected to the dryer.
12. Check tumbler bearing setscrews to ensure they are ALL tight.
I. PREOPERATIONAL TEST
ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test
should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or
due to marginal location (installation) conditions.
1. To start the dryer:
a. Microprocessor Controller (Computer) Dryers (refer to user’s manual included with dryer)
2. Check to ensure that the tumbler starts in the clockwise (CW) direction. Additionally, check the direction
of the blower motor (impellor/fan) to ensure that blower motor (impellor/fan) rotates in the clockwise
(CW) direction as viewed from the front. If it is, the phasing is correct. If the phasing is incorrect, reverse
two (2) of the leads at L1, L2, or L3 of the power supply connections made to the dryer.
IMPORTANT: Dryer blower motor (impellor/fan) as viewed from the front must turn in the clockwise
(CW) direction, otherwise dryer efficiency
will be drastically reduced and premature
component failure can result.
