necessary so that solvent vapors will not be drawn into the dryer inlet ducts. Dry
cleaner solvent vapors will decompose in contact with an open flame such as the gas
flame present in clothes dryers. The decomposition products are highly corrosive and
will cause damage to the dryer(s), ducts and clothes loads.
4. ELECTRICAL REQUIREMENTS. (Refer to schematic and wiring diagram). This dryer
is equipped with a control transformer for use on 208-240V-1PH-60Hz. The control voltage is
24V-60 Hz. The electrical power requirements necessary to operate the unit satisfactorily are
listed on the serial plate located on the back panel of each dryer. The electrical connection
should be made to the terminal in the control box on the rear of the unit, using #12 AWG for
208-240V (no neutral required).
It is absolutely necessary that the dryer be grounded to a known ground.
Individual circuit breakers for each stacked dryer are required. Use 15A or 20A circuit
breakers for 208-240V.
5. GAS REQUIREMENTS. The complete gas requirements necessary to operate the dryer
satisfactorily are listed on the serial plate located on the back panel of the dryer.
The inlet gas connection to the unit is 1/2-inch pipe thread. However, the size of the piping
to supply the dryer should be determined by reference to the National Fuel Gas Code ANSI
Z223.1A-1988 and consultation with the local gas supplier.
A joint compound resistant to the action of liquefied petroleum gases should be employed in
making pipe connections.
A 1/8 inch NPT plugged tapping, accessible for test gage connection, must be installed
immediately upstream of the gas supply connection to the dryer.
A drip tee is provided in the unit gas piping to catch dirt and other foreign articles.
All pipe connections should be checked for leakage with soap solution. Never check with an
open flame.
For altitudes above 2,000 feet [610m], it is necessary to derate the BTU input. Contact your
local distributor for instructions.
L.P. gas conversion kits are available for this dryer. Contact your local distributor.
6. PRESSURE TESTING. The dryer and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of that system at test pressure in
excess of 1/2 PSIG [35mbar]. The dryer must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 PSIG [35mbar].
7. EXHAUST INSTALLATION. (Refer to Figure 3 at the end of section 7.) Exhausting of
