Electrical Connections
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 right 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.

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) motor curve 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.

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.
For added personal safety, when possible, it is suggested
that a separate ground wire (size 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 a wire (size per local codes) and
securely clamped to bare metal at both ends.
Important
For personal safety and proper operation, the
dryer must be grounded.
Note
A grounding connection (terminal lug) is provided
in the dryer’s electrical service/relay box at the
rear, upper right hand corner of the dryer.
Grounding via metallic electrical conduit (pipe) is not
recommended
Provisions are made for ground connection in each dryer at
the electrical service connection area.
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’s
electrical service (relay) box.
Important
A separate protected circuit must be provided to
each dryer.
Gas Information _______________________
It is your responsibility to have all plumbing connections made
by a qualified professional to ensure 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.
The dryer and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess
of 1/2 psig (3.5 kPa).
