[d] OPERATION BOX
Be sure to attach the operation box before installing the unit. It is prepared at the factory to
be attached to the exit side of the top panel.
1) Remove the bolts at the exit side of the top panel. Then, attach the operation box.
2) Insert the two operation box cables from the cable cover (L) on the rear side into the
notch in the rear panel, and route them into the machine compartment. Then, remove
the four bolts from the top panel, put the cables in the accessory cable cover (S), and
use the separator inside to keep the two cables away from each other. Secure the cable
cover (S) by using the four bolts removed.
The accessory cable cover (S) should be hooked into the square hole in the back of the
operation box as shown in the illustration.
3) Remove the front panel, and pull the cables from the back of the machine compartment.
Coil and tie any extra length of cable to prevent contact with the fan blades and other
sharp edges.
4) Remove the plastic bag from the operation box connection cables coming out of the
control box, and connect the 4P and 7P connectors. Cover the cable connections with

3. VENTILATION
WARNING
1. Installation must be in accordance with applicable national, state, and local
regulations.
2. If an exhaust hood is required to discharge steam from the dishwasher, it
should provide a minimum 200 CFM at the entrance and 400 CFM at the
exit and be a listed and labeled factory-built commercial exhaust hood tested
in accordance with UL Standard 710 by a nationally recognized testing
laboratory.
It must be installed according to the terms of its listing and the manufacturer’s
installation instructions.
6
3. To use a gas water heater, thoroughly read its instruction manual. Ensure
adequate air intake and exhaust systems and exhaust hoods in accordance
with applicable national, state, and local regulations for the type and capacity
of the heater to prevent dangerous conditions due to lack of oxygen and toxic
gas generation.

4. WATER SUPPLY AND DRAIN CONNECTIONS
WARNING
Plumbing connections must comply with applicable sanitary, safety and
plumbing codes.
CAUTION
To prevent water leaks resulting in damage to the surrounding property, make
proper water supply and drain connections according to this manual.
[a] WATER HEATER CONNECTION
Make the water heater connection according to its instruction manual.
[b] PRESSURE REDUCING VALVE
Keep the water supply pressure within 10 to 70 PSIG.
If the water pressure is too high, a pressure reducing valve (not supplied) must be installed
in the water line just ahead of the dishwasher.
CAUTION
The pressure reducing valve must have a relief by-pass. Failure to use the
proper type of pressure reducing valve may result in damage to the unit.
[c] WATER SOFTENER
If water hardness exceeds 4 grains per gallon, a water softener (not supplied) must be
installed in the primary circuit (water supply inlet) of the water heater.
IMPORTANT
The recommended water hardness of not more than 4 grains per gallon is for
7
the dishwasher. If the required water hardness for the water heater is lower,
meet that requirement.
