3. STORAGE AND PRE-INSTALLATION
Important: Not performing the following procedures will invalidate the
product guarantee.
3.1 Checks to be carried out when the actuator is received
First of all check if the data on the nameplate (Model, Serial Number, Nominal Torque,
Nominal Voltage, Protection degree, Operating Speed, Protection Class, etc.) correspond to
the expected product data.
If the actuator is received already assembled onto the valve, the setting of the mechanical
stops and of the electric end-of-travel should have been already done during actuator
assembly onto the valve. An additional check is anyway recommended to verify that all the
requested settings have been completed as indicated in the present Instruction and
Operating Manual.
If the actuator is received separately from the valve, the setting of the mechanical stops and
of the electric end-of-travel must be checked and, if necessary, carried out while assembling
the actuator onto the valve. In any case, all the setting operations described in this
Instruction and Operating Manual must be carried out.
Check that the actuator was not damaged during transport: in particular, inspect the local
position indicator area glass. If necessary, repair all damages to the paint-coat, etc.
Check that the fitted accessories comply with those listed in the order acknowledgement
and the delivery note.
3.2 Storage procedure
3.2.1 GENERAL
The actuators leave the factory in perfect working conditions and with an excellent finish
(these conditions are guaranteed by an individual inspection certificate); in order to maintain
these characteristics until the actuator is installed on site, it is necessary to observe a few
rules and take appropriate measures during the storage period.
The base version of BIFFI actuators is weatherproof to IP 66/68. This condition can only be
maintained if the units are correctly installed and connected on site, and if they were
previously correctly stored. The standard plastic plugs used to close the cable entries are
not weatherproof, they just prevent the entry of undesired objects during transport.
3.2.2 STORAGE FOR A BRIEF PERIOD (LESS THAN ONE YEAR)
3.2.2.1 Indoor storage
- Make sure the actuators are kept in a dry place, laid on a wooden pallet (not directly on the
floor surface) and protected from dust;
- in very humid environments, a moisture absorbent desiccant packet should be introduced
in the motor enclosure. (Desiccant is not included in the actuator package).
3.2.2.2 Outdoor storage
- Make sure the actuators are protected from the direct action of weather agents (protection
by a canvas tarp or similar);
- place the actuators on a wooden pallet, or some raised platform, so that they are not in
direct contact with the ground, and protected from dust;
