GENERAL

The Model SD1 Dishwasher is a low temperature (140°F recommended, 120°F minimum), chemical sanitizing,
rack-type dishwasher for use with accessory 20" x 20" racks. It is equipped with a 1 HP thermally protected
(internal) pump motor. The motor must cool to restart the pump.

The revolving stainless steel ball bearing wash / rinse arms above and below provide thorough distribution of
water jets to all dishware surfaces. Arms are easily removable for cleaning and are interchangeable. Stainless
steel tubing connects upper and lower systems.

All three doors open together when the spring counter-balanced handle is raised. Durable door glides provide
easy opening and closing.

The SD1 can wash up to 37 racks per hour. Water usage is 1.7 gallons per rack.

After initial manual fill, the machine automatically washes a rack of dishes, drains the wash water, and then
refills with fresh water for the rinse cycle. The rinse water remains in the machine for the next wash cycle.
At the proper time during each cycle, an appropriate amount of detergent, rinse aid, and sanitizer chemicals
are pumped into the wash tank.

Cycle timing is as follows:

Wash 40 seconds
Drain 10 seconds
Flush 3 seconds
Fill 9 seconds
Rinse 20 seconds

INSTALLATION

UNPACKING

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

Prior to installation, verify that the electrical service agrees with the specifications on the machine data plate
which is located to the right of the control box.

LOCATION

Before finalizing machine location, make sure that consideration has been given for water supply, drain con­nection, electrical conduit, tabling, chemical containers and supply lines, as well as adequate clearance for
opening the doors. A hood or vent may be required in order to meet local codes.

LEVELING

The dishwasher must be level before any connections are made. With the dishwasher in its operating location,
turn the threaded feet as required to level the machine front-to-back and side-to-side.

CONVERTING FROM STRAIGHT-THROUGH TO CORNER OPERATION

The SD1 is shipped from the factory for straight-through oper­ation. To convert to corner operation, move the rack track and
splash guard as follows:

1. Remove the two screws and nuts that secure the front rack
track and splash guard (Figure 1) and remove the front rack
track and splash guard. Reassemble the front rack track and
splash guard by replacing the two screws and nuts in the
same mounting holes from which they were removed.

2. Remove the two screws and nuts at the outer edges of the
splash guard (Figure 2).

3. With the two screws and nuts removed in step 2, reattach the front rack track and splash guard to the
left side of the rack track assembly, using the mounting holes (Figure 3) provided.
