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 con -
sidered. 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
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 con -
nection 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.
Individual circuit breakers for each unit are recommended. Do not use ground-fault circuit breakers or
ground-fault circuit interrupter outlets. The wiring diagram is located on the belt guard on the 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.
