5. 3-Phase Wiring Connections
The only electrical input connections to the dryer are the 3-phase power leads (LI, L2, L3, N) and
ground. Single-phase power for the control circuit and for any single-phase motors (if present) is
done internally to the dryer. No single-phase input connection is required on a 3-phase dryer.
3-Phase Hookup
For dryers manufactured for operation at 3-phase, the electrical connections are made at the 3-pole
contactor (relay) located in the service box at the rear, upper left comer of the dryer. To gain access to
the service box and contactor, the service box cover must be removed. For models with a back guard,
the back guard must be removed to gain access to the service box.
Providing local codes permit, power to the dryer can be made by the use of a flexible U.L. listed cord/
pigtail (wire size must conform to the rating of the dryer), or the dryer can be hard wired directly to
the service breaker. The power supply wiring may enter the dryer through the top back area at the
outer top or relief should be used both where the wiring enters the dryer and the service box.
G. GAS INFORMATION
The dryer and its individual shut-off 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).
The dryer must be isolated from the gas supply piping system by closing its individual manual
shut-off valve during any pressure testing of the gas supply system at test pressures equal to or less
than 1/2 psig (3.5 kPa).
1. Gas Supply
The gas dryer installation must meet the American National Standard, National Fuel Gas Code ANSI
Z223.1-LATEST EDITION, as well as local codes and ordinances and must be done by a qualified
technician.

NOTE; Undersized gas piping will result in ignition problems, slow drying, increased use of
energy, and can create a safety hazard.
