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.
