Dexter Laundry B Series Operators Manual Installation & Operation Instructions page 13

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.
4. ELECTRICAL REQUIREMENTS: The electrical installation must be performed by a qualified electrical
technician.
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 at the terminal blocks
in the control box on the rear of the unit using conductors rated at 75 C (167 F) and a wire size adequate
to handle the amperage and voltage listed on the serial plate (see table below for recommended
minimum sizes). It is absolutely necessary that the dryer be grounded to a known (earth) ground (No. 8
AWG copper conductor recommended). Knock-outs are provided for the connection of 1 inch conduit for
the power supply conductors and 3/8 inch conduit for the external grounding conductor.
