TWINDOSE 35 – System for dishwashers 8 MAINTENANCE & ACCESSORIES 8.1 MAINTENANCE Routine maintenance of the TWINDOSE 35 involves taking out any encrustations that may have formed on the probe’s electrodes. It will also be necessary to change the peristaltic tubes for the detergent, rinse aid and sanitizer dosing pumps whenever they are found to have deteriorated. Thanks to SEKO technology, maintenance time is reduced to a minimum. Maintenance can be carried out on site, without having to remove the product. 8.1.1 Routine Inspection • Titrate the solution in the washing tank to check that the equipment is maintaining the correct concentration. • Clean the conductometric or inductive sensor. • Clean the TWINDOSE 35 casing using only a damp cloth. • Check the plumbing efficiency of the suction and discharge hoses. IT IS ADVISABLE TO DESCALE THE DISHWASHING MACHINE REGULARLY IN ORDER TO AVOID COMPROMISING CORRECT FUNCTIONING OF THE CONDUCTIVITY SENSORS. 8.1.2 Replacing the peristaltic hoses on the dosing pump Replace the pump hoses at regular intervals. Hoses should be replaced long before they become weak and burst. Should a hose burst, remove all the chemical product left in the pump, using a damp cloth. • Switch off the power supply before doing any maintenance work on the equipment. • Take the transparent lid off of the pump, removing the front cover screws if necessary • Before removing the old hose, position the roller arm in such a way that the rollers are in a vertical position. • Remove the old tube, starting from the left • Lift the tube and simultaneously rotate the roller arm clockwise. • Before inserting the new hose, put the roller arm in a horizontal position. • Insert the new tube with the connections placed in such a way that the flat sides are towards the front. • Insert the new tube starting from the left and simultaneously rotate the roller arm clockwise. • Make sure that the peristaltic tube is correctly positioned inside the pump. • Insert the front transparent cover all the way, putting the screws back in if necessary. 8.2 ACCESSORIES • Two-pole cable: 2x0.75 - H-05 RNF • T connector in PP for injection in the sanitizer pump • Intake nozzles with or without level probe. • Low-bulk tank side-connector, made of in PP, for injecting detergent.
