26 American Dryer Corp. 113409-2
OPTIONAL MANUAL BYPASS
Provisions are made in the dryer’s fire suppression system for the installation of an optional manual bypass. The
connections for the manual bypass are made at the “tee” or “three way” fitting, located in the outlet supply side of the
water solenoid valve. The manual ball cock shutoff valve must be located outside of the dryer at a distance from the
dryer where it is easily accessible. The use and connection of this manual bypass is at the option or discretion of the
owner.
The water connection for the manual bypass is made to the “tee” or “three way” fitting, which has a 3/8” F.N.P.T. and
a coupling must be used to provide the minimum 1/2-inch (12.7 mm) supply (feed) line.

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 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 AND ELECTRIC MODELS – the sail switch damper assembly was installed and pre-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. Check to be sure that the drive belts between the idler pulley and the motor pulley have been reconnected.
NOTE: The drive belts were disconnected at the factory prior to dryer shipment.
6. GAS MODELS – be sure that ALL gas shutoff valves are in the open position.
7. Be sure ALL back panels (guards) and electric box covers have been replaced.
8. Check ALL service doors to ensure that they are closed and secured in place.
9. Be sure the lint drawer is securely in place.
NOTE: LINT DRAWER MUST BE ALL THE WAY IN PLACE TO ACTIVATE THE SAFETY
SWITCH OTHERWISE THE DRYER WILL NOT START.
10. Rotate the tumbler (drum) by hand to be sure it moves freely.
