Due to the cartridge remaining in its seat for a long time and/
or to the presence of sediment, the force needed to extract the
cartridge might be such as to damage the accessory tool. In this
case it is intentional, because it is preferable to damage the tool
rather than the cartridge. If the key is lost or damaged, the same

operation can be performed with pliers.
Should one or more O-rings be lost or damaged during mainte-
nance operations on the non-return valve, they must be replaced.
Otherwise the system might not work correctly.
10.4 - Motor shaft
The electronic control of the system ensures smooth starts so as to avoid
excessive stress on the mechanical parts and thus prolong the life of the
product. In exceptional cases this characteristic could cause problems
in starting the pump: after a period of inactivity, perhaps with the system
drained, the salts dissolved in the water could have settled and formed
calcication between the moving part (motor shaft) and the xed part of
the pump, thus increasing the resistance on starting. In this case it may be
sufcient to help the motor shaft by hand to detach itself from the calcica-
tions. In this system the operation is possible because access to the motor
shaft from outside is guaranteed and a groove is provided at the end of the
shaft. Proceed as follows:
1. remove the motor shaft access cap as in Fig.27;
2. insert a straight tip screwdriver in the groove on the motor shaft
and manoeuvre, turning in 2 directions;
3. if it turns freely, the system can be started;
4. if rotation is blocked it cannot be removed by hand, call the as-
sistance service.
10.5 - Expansion Vessel
See paragraph 1.2 for the operations to check and adjust the air pressure
in the expansion vessel and to replace it if it is broken.
11 - UPDATING THE E.SYBOX FIRMWARE
11.1 - General
This chapter describes how to update one or more e.sybox units when you
have an e.sybox or an e.sylink with more recent rmware.
As already illustrated in the manual par. 9.4.2, to use the e.sybox in a
pumping set with a wireless connection, the e.sybox rmware versions
must all be the same.
