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 rating plate. 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
rating plate.
• 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. Installer must instruct the
user on how to correctly operate the dryer before leaving.
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 start-up), it has
a tendency not to ignite on the first ignition attempt. This is
because the gas supply piping is filled with air, so it may take
a few minutes for the air to be purged from the lines.
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.
NOTE: Water column pressure requirements (measured at
the pressure tap of the gas valve body) must be verified.
IMPORTANT: In most cases there is no regulator provided
in an L.P. dryer. The water column pressure must be
regulated at the source (L.P. tank), or an external regulator
must be added to each dryer.
!
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 a 3/4” B.S.P. adaptor. A
flexible supply line/coupling must be used in an effort to avoid
damaging the electric water solenoid valve.
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 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!!
