PARTIAL RESET: the user settings are reset, except the language and calibration

MAINTENANCE

Check the level of the tank containing the oil to be dosed regularly, to prevent the pumps from running dry. Even if the device does
not suffer any damage, this control is recommended to prevent damage resulting from lack of additive in the plant. The devices of the
eTwin series are designed for the level check. By applying the level probe (not included in the supply), you can monitor the level of the
liquid to be dosed contained in the tank. When this level drops below the minimum level established, the pumps stop automatically, a
warning appears on the display and the alarm relay 5 switches.
At least every 6 months, check operation of the pumps, tightening of the screws and sealing of the gaskets. Perform these checks
more frequently for particularly aggressive liquids. Especially check concentration of the additive in the plant. This concentration could
be reduced due to wear of the pinch tube (which must therefore be replaced) or clogging of the filter, which must be cleaned as
explained below.
The Manufacturer recommends cleaning the hydraulic part regularly (valves, filter and tubes). The frequency of this cleaning
operation cannot be established beforehand as it depends on the type of application, and neither can the reagent to be used be
established as it depends on the additive used.
Given these conditions, we can suggest how to intervene if the pump works with sodium hypochlorite (the most frequent situation):
1) Make sure it is switched off electrically (both polarities), disconnecting the conductors from the contact points of the mains by
means of the omnipolar switch with at least 3 mm between the contacts;
2) Disconnect the supply tube from the plant;
3) Remove the suction tube (with filter) from the tank and dip it in clean water;
4) Power on the pump and have it washed with water for 5÷10 minutes, making sure that no product residues are left in the hydraulic
parts;
5) With the pump disconnected, dip the filter in a solution of 10% hydrochloric acid and wait for the acid to finish its cleaning action;
