ELECTRICAL SERVICE SPECIFICATIONS (PER DRYER)
IMPORTANT:
NOTES: A.
B.
C.
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.

Electric Models Only
All electrically heated dryers must be connected to the
electric service shown on the dryer’s data label. The
connecting wires must be properly sized to handle the rated
current.
* 3-Wire is available. 8/8/08
Important
The dryer must be connected to the electric
supply shown on the data label. In the case of
208 VAC or 230/240 VAC, the supply voltage must match
the electric service specifications of the data label exactly.
Warning
208 VAC and 230/240 VAC are not the same.
Any damage done to dryer components due to
improper voltage connections will automatically void the
warranty.
Note
The manufacturer reserves the right to make
changes in specifications at any time without
notice or obligation.
Electrical Connections
Note
A wire diagram is included with each dryer and is
affixed to the back side of the top control
(access) door.
The only electrical input connections to the dryer are the
3-phase (3ø) power leads (L1, L2, and L3), ground, and in
the case of 4 wire service, the neutral. These electrical
connections are made at the terminal block located in the
service/relay box at the rear, upper left hand corner of the
dryer. To gain access into this service box, the service cover
must be removed.
The “line power” and the
“ground” connections to the
dryer must be made
through the knockout hole
at the top of the electric
service/relay box. A strain
relief must be used where
the line power ground wires
go into the electric service/
relay box.
Providing local codes permit, power connections to the dryer
can be made by use of a flexible UL listed power cord/pigtail
(wire must conform to ratings of the dryer), or the dryer can
be hard wired directly to the service breaker. In all cases, a
strain relief must be used where the wire(s) enter the dryer
electrical service (relay) box.
Note
A circuit servicing each dryer must be provided.
Grounding
A ground (earth) connection must be provided and installed
in accordance with state and local codes. In the absence of
these codes, grounding must conform to applicable
requirements of the National Electrical Code ANSI/NFPA NO.
70-LATEST EDITION, or in Canada, the installation must
conform to applicable Canada Standards: Canadian
Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST
EDITION. The ground connection may be to a proven earth
ground at the location service panel.
Note
A grounding connection (terminal lug) is provided
in the dryer’s electrical service/relay box at the
rear, upper left hand corner of the dryer.
For added personal safety, when possible, it is suggested
that a separate ground wire (sized per local codes) be
connected from the ground connection of the dryer to a
grounded cold water pipe. Do not ground to a gas pipe or
hot water pipe. The grounded cold water pipe must have
metal-to-metal connection all the way to the electrical ground.
If there are any nonmetallic interruptions, such as a meter,
pump, plastic, rubber, or other insulating connectors, they
must be jumped out with no. 4 copper wire and securely
clamped to bare metal at both ends.
Important
For personal safety and proper operation, the
dryer must be grounded. For proper operation of
the microprocessor controller (computer), an earth (zero)
ground is required.
Note
Grounding via metallic electrical conduit (pipe) is
not recommended.
Gas Information ______________________
It is your responsibility to have all plumbing connections
made by a qualified professional to assure that the gas
plumbing installation is adequate and conforms to local and
state regulations or codes. In the absence of such codes,
all plumbing connections, materials, and workmanship must
conform to the applicable requirements of the National Fuel
Gas Code ANSI Z223.1-LATEST EDITION, or in Canada,
the Canadian Installation Codes CAN/CGA-B149.1-M91
(Natural Gas) or CAN/CGA-B149.2-M91 (L.P. Gas) 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 and improper
operation of the dryer.
