INSTALLATION PROCEDURES
b. Electric Dryers 3 – Phase (3Ø) Hookup
The electrical input connection is made into the electric oven contactor located at the upper
rear of the dryer. Input connection wiring must be sized properly to handle the dryer's current
draw. This information is printed on the dryer's data label.
CAUTION: The dryer must be grounded. A ground lug has, been provided in the service box for
this purpose.
NOTE: A separate circuit serving each dryer must be provided.
The only electrical connections to the dryer are the 3 – phase (3Ø) leads (L1, L2, L3, and
sometimes neutral) and ground. Single – phase (1Ø) power for the control circuit is done by the
factory at the contactor (relay), and no other wiring connections are necessary.

stipulated in this manual, can result in personal injury and improper operation of
the dryer.
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 piping system at test pressures
equal to or less than 1/2 psig (3.5 kPa).
