American Dryer Corp. AD-100 - Manual (Page 4)

In the absence o£ such codes, all electrical construction and workmanship must
conform to the applicable requirements of the National Electric Code (ANSI Cl-1978).
Line power source requirements are shovm on the motor controls diagram located on
the inner side of the Reset (L.H. side) panel. Care must be taken to assure that
the impeller rotates in the direction of the arrow shown on the label located on
the impeller motor. Each dryer must be externally fused, NOTE: There are no
internal fused circuits on gas or steam dryers.
Actual voltage and current should be measured to insure proper operation of the
dryer.
(Motors are protected from overload but continuous operation of the motors at
above normal temperatures due to low voltage supply will greatly reduce their
operating life.)
GROUNDING.
A ground (earth) connection must be provided and installed in
accordance with local and state codes. In the absence of these codes, grounding
must conform to applicable requirements of the National Electric Code (ANSI Cl-1978).
A grounding lug is provided within the console (upper) junction box for this nurpose.
ELECTRIC DRYERS.
All electric dryers are 30 and provided with a 3 pole terminal
block for connecting the 3 proper size power cables, and a grounding lug identified
for that purpose.
Supply cables must be of copper and all 3 cables should be passed through one
large conduit. All electrical work should be performed by qualified electricians
in accordance with electric codes of the locale. In the absence of local electrical
construction codes, all electrical power, connections, including conduits, fuse or
circuit breakers, housings, wiring, wire terminations, insulation, etc. must conform,
to applicable requirements of the National Electric Code (ANSI Cl-1978).
GAS CONNECTOI^.
All gas dryers are provided with a 3/4" inlet pipe extending
to the upper rear of the dryer. (See Figure 41, Page 9-14) Proper size of gas
supply piping should be determined by the local gas sunplier and all piping
connections should be performed by qualified technicians in accordance with codes
of the locale. In the absence of local codes, the gas supply installation must
conform to the applicable requirements of the National Fuel Gas Code (ANSI Z223.1-
1974).
Access to the gas valve is via the control door at the front of the dryer and is
provided with a tap for regulating the gas pressure (natural or mixed gas). The
pressure is regulated to 4" water column pressure at the factory. (No Pressure
regulation is provided for dryers equipped to operate with liquid petroleum gases.
Your gas supplier must regulate the pressure of the gas supply. The dryer should
be operated at 10 1/2" W.C. pressure.) Add an external shut off for servicing
ease.
