Introduction of 5.5 litre ELBI solenoid
Background: On the 23/11/2004, the 5.5 litre ELBI solenoid was introduced into production for all 3
series Contours and Profilers. it was originally brought into production to try and prevent units from
failing to fill during a water limp error. it was found that the cause was not the limited flow (4 litre
ELBI) of the original solenoid but a water sensing issue. However the supplier of these solenoids
had already delivered 10,000 5.5 - litre solenoids, thus they were used in production.
Action: The introduction of the 5.5 litre solenoid is not expected to make any dramatic change to
the coolers operation. However there is a slight increase of water hammer occurring on the
premises. Tests conducted by our R&D department have proved that the hammer spike generated
by the 5.5 litre ELBI is no greater than our previous 12 litre soft close solenoid. Technicians can
identify the new 5.5 litre solenoid by a blue label that has been placed on the side of the solenoid
valve body.
