TWINDOSE 35 – System for dishwashers 1 FIRST OF ALL 1.1 WELCOME TWINDOSE 35 is a microprocessor dosing system that has a LED display and that uses potentiometer and DIPswitch settings. This unit embodies SEKO’s advanced technology and combines easy installation with a wide range of functions. TWINDOSE 35 has been designed to be used with all types of dishwashing machines (single tank and conveyor). The range available includes a series of models that are able to suit all the client’s needs. The concentration of the detergent solution is detected and kept unchanged by means of a conductometric sensor (to be installed inside the dishwasher) or by a timer control. Any shortage of the detergent dosed is picked up by the system’s OFA alarm function, which measures the detergent dosing time and, once the set time has expired, it warns the end user of the required concentration not having been reached by means of an buzzer. The rinse aid is dosed by means of a peristaltic pump, with either the pump rotation speed or the dosing time being set. The sanitizer (DLL or LLL versions only) is dosed by a peristaltic pump on which the speed is set. All settings are done using the keys on the front panel and potentiometers and DIP-switches that are clearly visible on the circuit. This manual contains instructions for configuring the TWINDOSE 35 to allow you to make use of all the advantages offered by the simplest and most versatile dosing system on the market. Please read this manual carefully, paying particular attention to the warnings and cautions related to the installation procedures. Always apply the necessary safety procedures, including the use of adequate personal protective equipment for your face, eyes, hands, and clothing. 1.2 PACK CONTENTS Before starting work, make sure that the pack contains the following: • Box complete with peristaltic pumps. • Foot filter (2) (3 for DLL and LLL versions) • Detergent injector (1) • Injection coupling with non-return valve (Rinse aid dosing) (1) • Sanitizer injector (1)* • T connector for rinse aid injector (1) • Fixing bracket with screws and wall plugs (1) • Conductometric sensor (1) • Conductometric sensor installation kit (1) • Jumpers (2) * Only on 3-pump versions TWINDOSE 35 code 0000136655 rev. 1.0 4

Check that the suction hoses are inserted in the jelly cans for the correct products. Use a multimeter to check all the electrical connections on the TWINDOSE 35. Applying the incorrect voltage could permanently damage the equipment and such damage is not covered by the guarantee. Do not connect to power supplies subject to widely fluctuating voltages and/or peak currents. When forming any electrical connections, refer to the wiring diagram in this manual. Check the voltage on the main power supply and make sure that it is between 80 and 265 Vac. WARNING: TWINDOSE 35 provides high voltage at the transformer connection. Always switch off the power supply before doing any maintenance work on the equipment. WARNING: During installation and when forming electrical connections, disconnect all power supplies to the dishwasher. Failure to respect the standards laid down in this manual could harm people or property, and either compromise the way the equipment operates or damage it. 1.5 MATERIALS REQUIRED FOR INSTALLATION • Two-pole cable: 2x1 - H-05 RNF for the external power supply • Two-pole cable: 2x1- H-05 RNF for the signal and conductometric sensor connection. • Suction and discharge hoses in Crystal PVC for the detergent pump. • Suction hose in Crystal PVC for the rinse aid suction pump. • Discharge hose in polythene for the rinse aid delivery pump. • Suction hose in Crystal PVC for the sanitizer suction pump (only on 3-pump systems). • Discharge hose in polythene for the sanitizer delivery pump (only on 3-pump systems).
