Electrical Requirements - Dexter Laundry C-Series Parts & Service Manual

MAKE-UP AIR
Adequate make-up air must be supplied to replace air exhausted by dryers on all types of installa-
tions. Provide a minimum make-up air opening to the outside for each dryer as follows:
Dryer Model Make-up Air Volume/Time
DC0030NC-10EC1X 830 CFM (23.5 m3/minute)
DC0030NC-39AC1X 690 CFM (19.5 m3/minute)
DC0050NC-10EC1X 910 CFM (25.8 m3/minute)
DC0050NC-39AC1X 760 CFM (21.5m3/minute)
DC0080NC-10EC1X 1200 CFM (34.0 m3/minute)
DC0080NC-39AC1X 1000 CFM (28.3 m3/minute)
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 airintakes of all dryers. Multiple openings should be provided.
NOTE: The following considerations must be observed for gas dryer installations where dry cleaners are
installed. 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 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.

ELECTRICAL REQUIREMENTS

The electrical power requirements necessary to operate the unit satisfactorily are listed on the se-
rial plate located on the back panel of each dryer. The electrical connection should be made to the termi-
nal block in the rear control box assembly on the rear of the unit, using a wire size adequate to handle the
amperage and voltage listed on the serial plate, but never smaller than No.12 AWG wire. It is absolutely
necessary that the dryer be grounded to a known ground.
Individual circuit breakers for each unit are recommended. The wiring diagram is located on the
belt guard onthe back of the machine.
TRANSIENT VOLTAGE SURGE SUPPRESSORS
Like most electrical equipment your new machine can be damaged or have its life shortened by voltage
surges due to lightning strikes which are not covered by factory warranty. Local power distribution
problems also can be detrimental to the life of electrical components. We recommend the installation of
transient voltage surge suppressors for your new equipment. These devices may be placed at the power
supply panel for the complete installation and don't require and individual device for each machine.
These surge protectors help to protect equipment from large spikes and also from small ongoing spikes
in the power that occur on a day to day basis. These smaller surges can shorten overall life of electrical
components of all types and cause their failure at a later date. Although they can't protect against all
events, these protective devices have a good reputation for significantly lengthening the useful life of
electronic components.
Electronic Components are helped to have a longer useful life when they are supplied with the clean
stable electrical power they like.
We are including the following names and links to a few suppliers of these devices for those who don't
currenty have a source.
