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 and state
regulations or codes. 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.
Important
Failure to comply with these codes or ordinances,
and/or the requirements stipulated in this manual
can result in personal injury or 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, which could cause a
fire hazard. 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.
An individual ground circuit must be provided to each
dryer, do not daisy chain.
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.
The dryer must be connected to the electric supply shown
on the data label. In the case of 208 VAC or 240 VAC, the
supply voltage must match the electric service
specifications of the data label exactly.
The wire size must be properly sized to handle the related
current.
Warning
208 VAC and 240 VAC are not the same. Any
damage done to dryer components due to
improper voltage connections will automatically void the
warranty.

208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering,
specify exact voltage.
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) type ONLY. For others,
calculate/verify correct breaker size according to appliance amp draw
rating and type of breaker used.
Circuit breakers for 3-phase (3ø) dryers must be 3-pole type.
