TECHNICAL INFORMATION
ESL
• Stainless steel electrode of small dimensions, with nylon holder for protection
against unintentional contact. A cable-bushing and a seal ring prevent the
connection terminal coming in contact with the water and, consequently,
oxidizing.
This electrode is used in metallic or non-metallic wells and storage tanks.
ES
• Electrode like type ESL, but provided with ballast.
EST
• Stainless steel electrode complete with extension rod and designed for use in
boilers, surge tanks and, generally speaking, in all cases where conditions of high
pressure and high temperature exist.
INSTRUCTIONS FOR INSTALLATION
• Do non install the electrode if a part of this is damaged.
• Before carryng out any installation operation, follow the instructions in this
leaflet carelully.
• Always disconnect the supply before carring out any connection, assembling or
commissioning operations on the electrode and make sure that the conductors
to connect or already connected to the terminals are not live.
• The installation should take place in accordance with the accident prevention
provisius in force.
• The cable section is given in the “Technical Specifications”
table, together
with the tightening torque value.
• We recommended using 1,5 mm² silicon conductors for the connection of these
electrodes to the associated level control relay.
• The cable that interconnect the relay to the electrodes should if possible be kept
separate from the supply cables, especially where long distances are involved. If
this is not possible, we recommend using of screened cables.
