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.
Connect the signal wires to a compatible voltage source.
WARNING!
Before 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 the Initial Charge, you do not set the Initial Charge to the full value you
need, but to that full value minus the Top-up dose time.
Example: If you need an Initial Charge of 70 seconds, and your Top-up dose is set to 15 seconds, then you actually set the Initial Charge
potentiometer to 55 seconds. (70 - 15 = 55)
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 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.
Model D2TT - Dish Machine with Two Solenoids
Connect the Top-up signal cable to the solenoid valve for top-up/rinse.
When the top-up signal activates the pump will run (at full speed) for the time programmed (0 to 30 seconds) on the upper right top-up dose
potentiometer. If the signal stops before the time setting is reached, the pump will stop.
Connect the Fill/Initial Charge signal cable to the fill solenoid.
When the fill signal activates, the pump runs (at full speed) for the time programmed (0 to 240 seconds) on the upper left initial charge
potentiometer. If the signal stops before the time setting is reached, the pump will stop.
Rinse Pumps - Signal Wiring and Programming
Model R1ST - Dish Machine with One Solenoid
Connect the signal cable to the solenoid valve for the rinse water.
CAUTION! Notice the setting potentiometers are reversed in position from the D1TT to the D2TT.
