Electrical Supply
The customer has the responsibility of ensuring that
the dishwasher electrical installation is in compli-
ance with all national and local electrical codes and
ordinances. The dishwasher is designed for an
electrical supply of 120V, 60 Hz, AC, connected to a
dishwasher-dedicated, properly grounded electrical
circuit with a fuse or breaker rated for 15 amps. If
the dishwasher is connected with a food disposer, a
20 amp (and no higher) fuse or circuit breaker may
be used. Electrical supply conductors shall be a
minimum #14 AWG copper wire.
Regardless of where the electrical supply cable
enters the enclosure (following the guidelines on
page 8), position the cable 21” (533mm) from the
enclosure’s left side, as shown in Figure 5, letter A.
Extend the cable 30” (762mm) from the enclosure’s
back, as shown in Figure 5, letter B.

CAUTION: Temperatures required for soldering
and sweating will damage the dishwasher’s
base and water inlet valve. If plumbing lines are
to be soldered or sweated, keep the heat
source at least 6 inches (152.4 mm) away from
the dishwasher’s base and water inlet valve.
Figure 7
Hot Water Supply
The hot water heater should be set to deliver
approximately 120° F (49° C) water to the dish-
washer. Water that is too hot can cause some
detergents to lose effectiveness. Lower water
temperatures will increase run times.
The hot water supply pressure must be between
15 - 145 psi (1 - 10 bars).
Hot Water Supply Plumbing
Install an easily accessible shut-off valve (not
supplied) in the hot water supply line, as shown in
Figure 7, letter B.
All solder connections must be made before the
water line is connected to the dishwasher’s water
inlet valve. Water may also be supplied to the
dishwasher by using a braided hose line. Check
with your local plumbing supply sources for the
proper hose and 90° elbow fitting.
NOTE: Regardless of where the hot water supply
line enters the enclosure (following the guidelines
on page 8), position the line 14” (355mm) from the
enclosure’s left side, as shown in Figure 7, letter A.
NOTE: Decide whether braided hose or copper
tubing will be used for the hot water supply
plumbing, and purchase the correct type of hot
water supply shut-off valve, 90° elbow, and
necessary fittings for the hot water supply plumb-
ing.
