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.
ELECTRICAL SERVICE SPECIFICATIONS (PER POCKET)
IMPORTANT:
208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering,
specify exact voltage.
NOTES:
A.
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.
B.
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.
C.
Circuit breakers for 3-phase (3ø) dryers must be 3-pole type.

Check your national and local codes for breaker and wire sizes
Grounding
A ground (earth) connection must be provided and installed
in accordance with local, state, and national regulations or
codes of the country of destination. In the absence of these
codes, grounding must conform to applicable requirements
of National Electric Code ANSI/NFPA 70, or in Canada, the
installation must conform to applicable Canada Standards:
Canadian Electric Code CSA C22.1. 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.
Provisions are made for ground connection in each dryer at
the electrical service connection area.

American Dryer Corp.
Electrical Connections
A wiring diagram is located behind the control panel for
connection data.
If local codes permit, power to the dryer can be made by the
use of a flexible UL listed power cord/pigtail (wire size must
conform to rating of dryer), or the dryer can be hard wired
directly to the service breaker panel. In both cases, a strain
relief must be installed where the wiring enters the dryer.
For CE Models Only
The means for disconnection from the supply must be
incorporated into wiring having a minimum contact
separation of 3.0 mm in all poles.
Single-Phase (1ø)
Wiring Connections / Hookup
The electrical input connections are made into the rear
service box located at the upper right area of the dryer. The
ground connection is made to the copper lug, also provided
in this box. To gain access, the service box cover must be
removed.
IMPORTANT: A strain relief must be used where the input
wiring enters the oven assembly.
Electrically Heated Models Only
The electrical input connections are made at the rear service
box located at the right upper section of the dryer. The ground
connection is made to a ground wire also provided in this
area. To gain access, remove rear service cover.
The only electrical input connections to the dryer are the
3-phase (3ø) power leads (L1, L2, L3, and sometimes
neutral) and ground. Single-phase (1ø) power for the control
circuit and for any single-phase (1ø) motors (if present) is
done internally to the dryer by the factory at the oven contactor.
No single-phase (1ø) input connection is required on a
3-phase (3ø) dryer.
The neutral will only be used on 4-wire service. This is
typical for 380-416V, 50 Hz.
CAUTION: The dryer must be grounded. A ground lug
has been provided for this purpose.
Input connection wiring must be sized properly to handle
the dryer's current draw. This information is printed on the
dryer's data label.
Gas Information ______________________
It is your responsibility to have all plumbing connections,
materials, and workmanship conform to local and state
regulations or codes of the country of destination. In the
absence of such codes, all plumbing connections,
materials, and workmanship must conform to the applicable
local requirements. In the USA this is National Fuel Gas
Code ANSI Z223.1/NFPA 54, or in Canada, Natural Gas and
Propane Installation Code CSA B149.1.
In Australia, the fuel gas code is AS/NZS5601, local authority,
gas, electricity, and any other relevant statutory regulations.
It is important that gas pressure regulators meet applicable
pressure requirements, and that gas meters be rated for
the total amount of all the appliance Btu being supplied.
