3. MAKE-UP AIR: Adequate make-up air must be supplied to replace air exhausted by dryers on all types of
installations. Refer to specifications for the minimum amount of make-up air opening to outside for each dryer.
This is a net requirement of effective area. Screens, grills or louvers, which will restrict the flow of air, must be
considered. Consult the supplier to determine the free area equivalent for the grill being used. The source of
make-up air should be located sufficiently away from the dryers to allow an even airflow to the air intakes
of all dryers. Multiple openings should be provided.
The sources of all make-up air and room ventilation air movement to all dryers must be located away
from any dry cleaners. This is necessary so that solvent vapors will not be drawn into the dryer inlet
ducts. Dry cleaner solvent vapors will decompose in contact with 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.
The operation of this appliance may affect the operation of other types of gas appliances, which take
their air for safe combustion from the same room. Adequate ventilation must be provided to avoid back
flow of gasses from other appliances in the same room. All other gas appliances should be tested with
the Dexter dryer in operation and all the windows and doors closed. If in doubt consult the appliance
manufacturer(s).
4. ELECTRICAL REQUIREMENTS. The electrical power requirements necessary to operate the unit satisfactorily
are listed on the serial plate located on the back panel of each dryer and in the specifications section of
this manual. The electrical connection should be made to the terminal board, on the rear of the unit. It is
absolutely necessary that the dryer be grounded to a known ground. Individual circuit breakers for each
dryer are required.
The installer must provide a disconnect switch which will interrupt both lines. It may be a local or national
requirement to provide an electrical interruption switch visible and accessible from the room in which the
dryer is installed. The wiring diagram is located on the belt guard on back of the dryer.
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 and in the specifications section of this
manual. The inlet gas connection to the unit is 1/2-inch [12.7] pipe thread for T-30 and T-50 and 3/4-inch
[19.1] for T-80 and T-120. However, the size of the piping to supply the dryer should be determined by
reference to the National Fuel Gas Code ANSI Z223.1A and consultation with the local gas supplier.
