Installation Instructions

DDU38 DIRECT-DRIVE UNLOADER

GENERAL

The DDU38 Unloader is connected to the unload end of a C-Line A, W, or AW dishwasher. It moves
the 20" x 20" rack in a 90 degree arc onto a dish table. The Unloader uses a direct linkage with the
dishwasher cradle to oscillate the rack-moving mechanism.

NOTE: The Unloader cannot be installed on dishwashers having either the Blower Dryer or the frame­mounted Electric Booster Heater options.

INSTALLATION

UNPACKING

Immediately after unpacking, check for possible shipping damage. If the Unloader is found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery.

LOCATION

CAUTION: Do not use a forklift to move or unskid machine.

Place Dishwasher and Unloader as close to their final positions as possible. Review all tags and labels
but do not remove any until installation is complete. Remove any packaging, tape, wire, and bracing.

ASSEMBLY

Leg Installation and Leveling

Insert the long legset into the two rear leg
sockets underneath the Unloader (Fig.1).
Insert the short legset into the two front leg
sockets. Fasten legs to leg sockets by
loosening and tightening the set screw in
each leg socket. Fill set screws with an NSF
approved silicone sealant.

Make sure adjoining parts of Dishwasher and
Unloader are exactly in line with each other.
Turn leveling feet (on bottom of legs) in or out
to adjust height and level machine. Also,
refer to Track Guide Leveling, page 6.
