2. Electrical Service Specifications

IMPORTANT:

The dryer

must be

connected to the electric supply shown on the data label that is

affixed to the right side of the main electrical enclosure. In the case of 208 VAC or

240 VAC, the supply voltage

must match

the electric service specifications of the

data label

exactly

WARNING: 208 VAC and 240 VAC ARE NOT THE SAME.

Any damage done to the dryer

components due to improper voltage will automatically VOID THE WARRANTY.

IMPORTANT:

For proper sprinkler and dryer operation, sprinkler

must be

or dedicated single-phase (1ø) multi-wire branch circuit at dryers nameplate voltage.

NOTE:

For 4-wire service, cap the neutral.
