USE AND MAINTENANCE MANUAL
DANGER
This appliance can be used by children aged 8 years or over and by persons with limited physical, sensory or
intellectual capabilities, or with limited experience and knowledge, provided that they are supervised or have
been instructed in the safe use of the appliance and are aware of the dangers involved. Children must not be
allowed to play with the appliance. Cleaning and user maintenance must not be carried out by children unless
they are supervised
Use a suction pump (2) with a diameter equivalent to that of the suction mouth of the electropump (1).
If the height (HA) is over 4 meters use a tube with a larger diameter. The suction line should be perfectly airtight.
No elbows and/or slopes should be present to prevent the formation of air locks that could affect the electropump
efficiency. A foot valve (3) with filter (4) should be fitted at about half a metre below the fluid that has to be pumped
(HI) on one end of the line. Load losses can be reduced using delivery piping with a diameter equivalent or greater
than the electropump mouth.
A cut-off valve (5) should also be installed downstream from the check valve, to facilitate servicing operations.
Piping should be fitted so that vibrations, when existing, tension and weight do not affect the pump. Piping should
be routed along the shortest and straighter track, avoiding an excessive number of bends. Verify that the motor is
properly ventilated.
For fixed installations, the autoclave base should be secured to the support surface by fastening screws into the
slots located on the tank feet, connecting the system with a hose portion and inserting a rubber layer between the
support surface and the autoclave (or other vibration-damping material) to reduce the vibra.
The place of installation must be steady and dry to ensure proper and uninterrupted operation of the booster set
ATTENTION!
Connection, suction and delivery pipes should be connected with the utmost care. Make sure that all connections
fixed by means of screws are sealed. Avoid applying excessive stress to tighten the screws of connections or of
other components. Use a Teflon tape to completely seal all joints.
CHAPTER 4
ELECTRICAL CONNECTIONS
DANGER
In the event of system leaks, the pump may remain on even without water request, causing an overheating of
the pumped fluid, with consequent risk of burns. In this case, be very careful, disconnect the power supply
and wait for the system to cool down before carrying out any operation.
WARNING
Verify that the voltage and frequency of the electropump shown on the nameplate correspond to those
available on the mains.
DANGER - ELECTRIC SHOCK RISK
The installer must make sure that the electric system is grounded in accordance with the law in force.
DANGER - ELECTRIC SHOCK RISK
The pump is to be supplied through a residual current device (RCD) having a rated residual operating
current not exceeding 30 mA
