		ONLY. Calculate/determine correct fuse value, by applying either local and/or National Electrical
	B.	Codes to listed appliance amp draw data.
		Circuit breakers are thermal-magnetic (industrial) type ONLY. For others, calculate/verify correct
	C.	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 local, state, and national regulations or codes of the country of origin. 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.

Provisions are made for ground connection in each dryer at the electrical service connection area.

Warning

!Electrical Grounding Instructions – This dryer is equipped with a 3-prong (grounding) plug for your

protection against shock hazard and should be plugged directly into a properly grounded 3-prong receptacle. Do not cut or remove the grounding prong from this plug.

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 3.0mm 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.
