Page 9: Hydraulic Connections
2.5 HYDRAULIC CONNECTIONS The CD model enables the dosage of liquid detergent by means of the peristaltic pump, or the dosage of solid detergent by piloting the solenoid valve, which, by regulating the water flow into the dispenser containing the detergent, whether it is granular or in tabs, enables it to dissolve and enter the tank. -

2.5.2 INSTALLATION FOR DOSING SOLID DETERGENT To dose solid detergent, it will be necessary to connect the solenoid valve to the pump output (see Fig. 6). The device will pilot the opening and closing of the solenoid valve to regulate water flow. Fig. -

3.0 PROGRAMMING 3.1 MAIN FEATURES . 9 - U NTERFACE The Increase/Decrease keys allow to change the numerical values and scroll through the lists of options for all the available menu entries. The Enter key allows to access and exit from the various entries of the submenus. Pressing the key for 3 seconds allows, from the Initial Menu, to access the Programming Menu and to go back to the Menu one level up from the main entries on a Menu;... - Page 12 Flow Rate Percentage = 100 * (Nominal Flow Rate/ Read conductivity :1% - 65% Set-point value Effective Flow Rate); Flow Rate Percentage = Read conductivity :65% - 90% Set-point value 80 * (Nominal Flow Rate/ Effective Flow Rate); ...
- Page 13 As in the previous example, the solenoid valve will remain open, thus enabling the passage of water flow until reaching a value of 10 units (~ 110%), and will start dosing again only when the value of measured conductivity goes below 8 units (hysteresis around the Set-point value). The measured conductivity value of a solution is influenced by the temperature as well, and to compensate for this influence you need to know its value.

The t.on and t.oF entries are visible on the Settings Menu only in the case in which the pump is programmed to pilot the solenoid valve, otherwise by C.d.t, by pressing the F key, it goes back to the first entry of the Settings Menu. To go back to the Programming Menu, to the InP entry, just press Enter for 3 seconds from any entry of the Menu. -

Page 24: Returning Material To The After-Sales Service
Problem: liquid leaking from the peristaltic tube Solution: 1. Make sure the delivery and intake tubes are inserted properly and the ring nuts are well tightened. 2. Check the status of the peristaltic tube. If evident malformations are detected, make sure that the material is compatible with the product being dosed by consulting the chemical compatibility table (see ANNEX D), and then go ahead with the replacement. -
