Electrical Connections/Time Delay Relay
ELECTRICAL CONNECTIONS
Connect the incoming line power and disposer motor
to the labeled terminal block in the control center. Use
appropriate voltage and phase electrical connection
diagrams at the back of this manual. Wire the disposer
motor for the correct voltage using the connection
diagram inside the motor terminal box.
Make sure the solenoid valve is the same voltage as the
control panel and supply power.
Connect water solenoid valve as shown in the wiring
diagrams on pages 8, 9, 10 and 11.
Wire per local electrical code using 7/8" diameter holes
in bottom of control center cabinet and install NEMA 4
watertight electrical connectors (not supplied).
After completing the connections, close door and fasten
all locking clamps. Replace disposer motor cover.
TIME DELAY RELAY
The time delay relay may be used with the CC-202D
to delay solenoid valve shut-off, providing a post flush.
This helps prevent drain line stoppages and is
beneficial when ground food waste must travel through
many bends or a long horizontal run. It is adjustable
from 0 to 10 minutes and factory set to provide
approximately a 5 minute delay. To adjust,

ELECTRIC POWER
. Inside unit, locate the adjustment
potentiometer. Turn clockwise to increase delay. Turn
counterclockwise to decrease delay. See Figures 3 and
4 for wiring.
Ensure the voltage rating on the time delay relay and
solenoid valve are the same as the dispos
er motor and
line voltage.

ELECTRIC SHOCK
• Turn off the electrical supply to the disposer before
attempting any work on it. Use a voltmeter or
circuit tester to ensure that power is off.
• All Installation work must conform to local
plumbing and electrical codes.
• All control centers and disposers must be carefully
and permanently grounded.
• A properly fused disconnect must be installed at
the electrical supply source for the control center.
PROPERTY DAMAGE
• Ensure that control center voltage and phase
match the disposer motor and electrical supply.
Check name plates on disposer and control
centers for voltage and phase specifications.
• Refer to the control center wiring diagrams in this
manual for correct connection.
• Use NEMA 4 watertight electrical connectors (not
supplied) when making electrical connections to
the control center.
