The fire suppression system must be supplied with a minimum water pipe size of
If the rear area of the dryer or the water supply is located in an area where it will be exposed to cold/freezing temperatures, provisions must be made to protect these water lines from freezing.
Warning
!If the water in the supply line or water solenoid valve freezes, the fire suppression system will be
inoperative!!
Water Connections
The water connection is made to the

N.P.T. The sealing of an NH connection is made with a washer opposed to the mating threads of an N.P.T. assembly. The 2 thread designs are not compatible.
It is recommended that a filter or strainer be installed in the water supply line.
Important
!Flexible supply line/coupling must be used. Solenoid valve failure due to hard plumbing
connections will void warranty.
The dryer is to be connected to the water mains using a new hose set and the old hose set should not be reused.
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
Electrical Requirements
No independent external power source or supply connection is necessary. The
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!!
Preparation for Operation/Start-Up ___
The following items should be checked before attempting to operate the dryer:
•Read all “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer.
•Check incoming supply voltage to be sure that it is the same as indicated on the data label. In the case of
208 VAC or 240 VAC, the supply voltage must match the electric service exactly.
•GAS MODELS – Check to ensure that the dryer is connected to the type of heat/gas indicated on the dryer data label.
•GAS MODELS – Be sure that all gas shutoff valves are in the open position.
•Be sure all back panels (guards) and electric box covers are in place.
•Be sure the service doors are closed and securely in place.
•Be sure the lint door/drawer is securely in place.
•Rotate the tumbler (drum) by hand to be sure it moves freely.
•Check bolts, nuts, screws, terminals, and fittings for tightness and security.
•Check that the vent is connected to the dryer and is exhausted to the outdoors.
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.
Turn on electric power to the dryer.
Refer to the Operating Instructions for starting your particular model dryer.
Gas Dryers
Open all shutoff valves.
When a gas dryer is first started (during initial
Note
!During the purging period, check to be sure that all gas shutoff valves are open.
A gas pressure test should be taken at the gas valve pressure tap of each dryer to ensure that the water column pressure is correct and consistent.
