2.O3 Mechanical Installation
(continued)
Installing the Rinse and Detergent Supply and Discharge Tubes
1) Install the included PVC pump supply tube (4mm ID, 6mm OD) into the chemical container using the foot filter with screen
and weight to position the tube at the bottom of the container.
2) Route the other end of the included PVC pump supply tubes from supply containers to the inlet sides (left) of each
respective pump. Slip the tube fully through the compression nut into fitting and tighten.
3) Route pump discharge tubes to the outlet sides (right) of each respective pump. Slip the tube fully through compression
nut into fitting and tighten.
4) Route the other end the pump discharge tube to the appropriate injection fitting (see the injection fitting installation
instructions on previous page for more detail). Slip the tube fully through the compression nut onto fitting nipple and
tighten.
NOTE:
Try to keep both the supply and discharge hoses as straight as possible, avoiding all unnecessary bends.
2.O4 Electrical Installation
Installing the Detergent and Rinse Supply Signal Wiring
NOTE:
All electrical connections must either be in the dish machine control circuit panel or an external junction box. The
dispenser is pre-wired with a multi-conductor electrical cable that may need to be run through a conduit to the location where
hard-wired connections are made on the dish machine. If this is the case use approved water tight conduit that meets local
and national codes
Depending on the model of the CP-500, there will be one or two pairs of signal/power wires that need to be connected to the
dish machine. Using the table below, connect the signal wires to a compatible voltage source.
WARNING!
Before performing any work on the CP-500, you must disconnect the power supply voltage of the dish
machine.
CAUTION!
Verify that electrical grounding is functional and complies with local regulations. Verify that the rated values
of the pump are compatible with those of the power supply. Never install the pump directly in parallel with inductive
loads (e.g. motors/solenoid valves). If necessary, use an isolating relay.

Detergent Pumps - Signal Wiring and Programming
Model D1TT - Dish Machine with One Solenoid
Connect the signal cable to the solenoid valve for top up/rinse.
When the signal is activated, the pump will run for the time programmed
(0 to 30 seconds) on the upper left top-up dose potentiometer. If the
signal stops before the time setting is reached, the pump will stop.
If the signal
is still active after 30 seconds, the pump will then run (or
continue to run) using the setting (0-240 sec) of the upper right initial
charge potentiometer.
Because the pump always runs the Top-up dose and runs it before ...
