5.0 - FIRST START-UP
• Before start-up make sure that all of the instructions on the rating plate, including the direction of flow, are observed;
• After having gradually pressurized the system, check the seal 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
• Check tightness of the flanged/threaded connections on the system;
• Check tightness and operation of the solenoid valve;
It is the responsibility of the final user or installer to define the frequency of these checks based on the severity of the service
conditions.
6.0 - MAINTENANCE
No maintenance operations need to be carried out inside the device.
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 (5) needs to be changed following an electrical failure, we recommend changing the connector (2) as well.
The coil and/or connector replacement operations need to be carried out taking care to ensure the product's IP65 rating.
6.1 - REPLACING THE CONNECTOR
• Unscrew and remove the central screw (6), then remove the connector (2) from the coil (5);
• 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 (6), then remove the connector (2) from the coil (5);
• Loosen the ring nut (7) that locks the coil (5) and take it out from the armature assembly along with the gaskets;
• Insert the new coil + seals into the armature assembly and secure everything with the screw;
• Couple the connector to the coil and secure it as indicated in 3.2;
• If it is necessary to set up the wiring, proceed as described in 3.2.
7.0 - TRANSPORT, STORAGE AND DISPOSAL
• During transport the material needs to be handled with care, avoiding any impact or vibrations to the device;
• If the product has any surface treatments (ex. painting, cataphoresis, etc) it must not be damaged during transport;
• The transport and storage temperatures must observe the values provided on the rating plate;
• If the device is not installed immediately after delivery it must be correctly placed in storage in a dry and clean place;
• In humid facilities, it is necessary to use driers or heating to avoid condensation.
• At the end of its service life, the product is to be disposed of separately from other waste (WEEE directive 2012/19/
EU) and in compliance with the legislation in force in the country where this operation is performed.
