3. Electrical Requirements
No independent external power source or supply connection is necessary. The 24 volt power to operate the
fire suppression system is accomplished internally in the dryer (from the dryer controls).
WARNING: Electrical power must be provided to the dryer at ALL times. If the main electrical
power supply to the dryer is disconnected, the fire suppression system is
INOPERATIVE!!
I. PREPARATION FOR OPERATION/START-UP
The following items should be checked before attempting to operate the dryer:
1. Read and follow 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 the case
of 208 VAC or 240 VAC, the supply voltage must match the electric service exactly.
3. GAS MODELS - check to ensure that the dryer is connected to the type of heat/gas indicated on the dryer
data label.
4. GAS MODELS - 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. (Refer to page 29 for sail switch adjustment.)
5. GAS MODELS - be sure that ALL gas shutoff valves are in the open position.
6. Be sure ALL back panels (guards) and electric box cover have been replaced.
7. Check ALL service doors to ensure that they are closed and secured in place.
8. Be sure the lint drawer is closed and 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 basket (tumbler/drum) by hand to be sure it moves freely.
10. Check bolts, nuts, screws, terminals, and fittings for security.
11. STEAM MODELS - check to insure air supply (80 psi [5.51 bar]) is supplied to dryer.
12. STEAM MODELS - check to insure ALL steam shutoff valves are open.
13. STEAM MODELS - check steam damper operation.
14. Check basket (tumbler) bearing setscrews to insure they are ALL tight.
