Electrical Information _________________
Electrical Requirements
All electrical connections must be made by a properly
licensed and competent electrician. This is to ensure that
the electrical installation is adequate and conforms to local,
state, and national regulations or codes of the country of
destination. In the absence of such codes, all electrical
connections, materials, and workmanship must conform to
the applicable requirements of the National Electrical Code
ANSI/NFPA NO. 70-LATEST EDITION or in Canada, the
Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or
LATEST EDITION.
For personal safety, the dryer must be electrically grounded
in accordance with local codes and/or the National Electrical
Code ANSI/NFPA NO. 70-LATEST EDITION or in Canada,
the Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990
or LATEST EDITION.
IMPORTANT:
Failure to comply with these codes or
ordinances, and/or the requirements stipulated in this
manual can result in component failure.
NOTE:
Component failure due to improper installation will
void the warranty.
Each dryer should be connected to an independently
protected branch circuit. The dryer must be connected with
copper wire only. Do not use aluminum wire. The copper
conductor wire/cable must be of proper ampacity and
insulation in accordance with electric codes for making all
service connections.
NOTE:
The use of aluminum wire will void the warranty.
Component failure due to improper voltage application
will void the warranty.
The manufacturer reserves the right to make changes in
specifications at any time without notice or obligation.
IMPORTANT:
A separate protected circuit must be
provided to each dryer.
It is necessary to have a power disconnect for each dryer.
These disconnects must be located within 30 feet (9
meters) of the dryer.
The dryer must be connected to the electric supply shown
on the data label.
Electrical Service Specifications
If it is not feasible to provide separate exhaust ducts for
each dryer, ducts from individual dryers may be channeled
into a “common main duct.” The individual ducts should
enter the bottom or side of the main duct at an angle not
more than 45º in the direction of airflow. The main duct
should be tapered, with the diameter increasing before each
individual duct is added.
IMPORTANT:
To maintain proper performance, no more
than 4 dryers should be connected to 1 main common
duct.
The illustration below shows the minimum cross-sectional
area for multiple dryer round or square venting. These
figures must be increased if the main duct run from the last
dryer to where it exhausts to the outdoors is longer than “B”
feet (“B” meters) or has more than 1 elbow in it.
NOTE 1
Opening from combustible materials must be 2-inches (5.08 cm)
larger than the duct (all the way around). The duct must be centered
within this opening.
NOTE 2
Distance should be 2 times the diameter of the duct to the nearest
obstruction.

NOTES:
A.
B.
When fuses are used they must be dual element, time delay, current
limiting, class RK1 or RK5 ONLY. Calculate/determine correct fuse
value, by applying either local and/or National Electrical Codes to
listed appliance amp draw data.
Circuit breakers are thermal-magnetic (industrial) motor curve type
ONLY. For others, calculate/verify correct breaker size according to
appliance amp draw rating and type of breaker used.
