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, state, and national regulations or codes of the country of origin. 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.
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 pocket 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 pocket, 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 pocket.
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.
Warning (Gas Models Only – Export)
!Dryers built for use with a voltage between 200 and 240 must verify the input voltage during
installation. If the nominal voltage is outside of the medium tolerances shown on the diagram below, adjust the autotransformers, located near the burner assemblies. To adjust the autotransformer wiring, place the red wire on the appropriate tap (HIGH, MED, LOW) of the autotransformer. For additional wiring details, refer to the electrical diagram located on the inside of the control panel.
