INSTRUCTIONS FOR DISMANTLING THE MIXER
Before proceeding to partially or totally dismantle the machine, the regulations regarding safe preparation of
the machine and the work area must be strictly adhered to.
In order to safely work on the mixer, an on-load switch capable of disconnecting power to
the mixer itself must be positioned in the vicinity of the mixer (within reach of the
maintenance technician). Alternatively, the automatic switch should be located on the
electrical panel in the equipment room (which safeguards the line connected to the mixer)
and it should be possible to lock this in an open position using a lock, so that the
maintenance technician can keep it nearby during maintenance operations.
Before carrying out any maintenance on the mixer and its component parts, disconnect the
dedicated switches (to the mixer and any other parts) and ensure that these cannot be accidentally
reconnected.
Put up a warning sign!
Follow the instructions relating to the safety regulations in Chapter 2, as well those relating to installing the
mixer in Chapter 8, extremely carefully.
When performing repair or maintenance operations, reduce the level of contents in the tank as
necessary (particularly when carrying out maintenance on wall-mounted mixers).
Warning! In areas with potentially explosive atmospheres, it is absolutely prohibited to:
-
Perform any repair or maintenance operations,
-
Introduce any flammable source (e.g. naked flames, heat sources, equipment without arc flash protection,
non-explosion-proof electrical devices).
-
Carry out welding operations, or machining operations that may generate flames or sparks.
ONLY use spark-proof tools
Authorisation must be requested from the Health and Safety (RSPP) Manager before performing
any operation, and the required documentation must be filled out correctly to obtain authorisation to
work in potentially explosive areas; this authorisation must be duly signed by the authorised
personnel.
When the safety conditions have been established, you may proceed to dismantle the parts.
COMPLETE REMOVAL:
-
prepare the machine for lifting using a crane, by hooking chains or straps onto the dedicated points of the
frame of the machine.
-
unhook the electrical cables and the hydraulic pipes on the mixer side.
-
completely remove the nuts or fixing screws of the frame from the wall or the counter-frame.
-
remove the machine from its fixed position.
-
remove the internal part of the machine, taking care not to bring it into contact with the walls of the tank or
other internal parts of the tank.
-
place the mixer in an area outside of the atex zones in order to proceed with maintenance operations.
