First Start-Up - Madas M16/RM N.A. Manual De Instrucciones

5.0 - FIRST START-UP

• Before start-up, make sure that all the instructions on the rating plate, including the direction of flow, are observed;
• After having gradually pressurised the system, check tightness and operation of the solenoid valve, electrically
powering/disconnecting the connector ONLY IF connected to the coil.
IMPORTANT NOTE: Do not use the connector as a switch to close the solenoid valve.
• Make sure the solenoid valve is closed by electrically connecting it.
5.1 - RECOMMENDED PERIODIC CHECKS
• Use a suitable calibrated tool to ensure the bolts are tightened as indicated in 3.2;
• Check the tightness of the flanged/threaded connections on the system;
• Check the tightness and operation of the solenoid valve;
The final user or installer is responsible for defining the frequency of these checks based on the severity of the service conditions.
6.0 - MAINTENANCE
On completion of the operations described below, repeat the procedure indicated in paragraph 5.
If the coil and/or connector need to be replaced (see fig. 1):
• Before performing any operation, make sure that the device is not electrically powered;
NOTE: if the coil (13) needs to be changed following an electrical failure, we recommend changing the connector (10) as well.
The coil and/or connector replacement operations need to be carried out taking care to ensure the product's IP65 protection
rating.
6.1 - REPLACING THE CONNECTOR
• Fully unscrew and remove the central screw (11), then remove the connector (10) from the coil (13);
• When you have taken out the existing internal electrical wiring, wire the new connector and secure it to the coil, as shown in 3.2.
6.2 - REPLACING THE COIL
• Fully unscrew and remove the central screw (11), then remove the connector (10) from the coil (13);
• Loosen the screw (12) that locks the coil (13) and take it out from the armature assembly along with the gaskets/discs;
• Place the new coil + gaskets + discs inside the armature assembly and secure with the screw;
• Couple the connector to the coil and secure it as shown in 3.2;
• If it is necessary to set up the wiring, proceed as described in 3.2.
NOTE: No maintenance operations need to be carried out inside the device.
If an internal inspection is required, it is advisable to:
• Also check the integrity of the obturator (9) and, if necessary, replace the rubber seal (8);
• Replace the gaskets before reassembling.
• In any case, before carrying out any dismantling operation on the device, make sure that there is no pressurised
gas inside.
