IMER INTERNATIONAL S.p.A.
IMER MORTAR MIXERS
7. MECHANICAL SAFETY
The hazardous points on the IMER mortar mixer are protected
by means of suitable safety devices, which must remain fitted
at all times and kept in perfect condition, such as the electric
motor cooling fan guard, the grid on the hopper, the vibro-
screen and the hopper cover to prevent contact with the mixer.
All elements are connected to a safety sensor: when disen-
gaged, all moving parts of the machine are shut down.
8. TRANSPORT (see fig.3/4)
- Caution! Before moving the mortar mixer, always
detach the power plug.
Before moving the mortar mixer the air hose and material delivery
line must be removed.
Only a minimal amount of the material should be in the hopper
when handling.
Move the machine by means of the specific handles.
- Caution! Before lifting the mortar mixer, always
disassemble the compressor for separate transport.
- Caution! Before lifting the machine, always check
that all machine components are correctly secured and
fitted in place.
To lift the machine, use the three specific attachment points.
- Caution! Lift with care to avoid hazardous
oscillations
- Caution! Never use points other than as specified
in figure 3 to lift the machine.
Use lifting equipment suited to the overall weight of the machine
indicated in table 1.
9. INSTALLATION
Position the mortar mixer in a suitably ventilated environment
where it does not constitute an obstruction either during use or
cleaning at the end of the work shift and where a minimum
quantity of pipelines is required.
Place the machine according to the application in a clear area if
ready-to-use bags are fed into the machine: below the mixer
outlet in the case of mixes being mixed on site. The machine
must always be placed on a flat surface or slightly inclined
towards the material outlet.
Route machine pipelines as required by the product application,
avoid excessive bends or kinks on the hoses. If pipelines are
routed upwards, secure the lines to scaffolding or other support
points.
Apply or connect the accessories required fro the specific
application, with reference to paragraph 4.2
Always connect the remote control supplied in the case of use
without compressed air or when using compressors with
capacity of over 400 l/min
10. CONNECTIONS
10.1 ELECTRICAL CONNECTION (see fig.5)
- Ensure that the power supply voltage, mains
frequency and electrical connection (socket, fuses, cable)
correspond to specifications in table 1.
The electrical power line must be fitted with protection against
current overload (e.g. by means of fuses or a thermal magnetic
cut-out) and against indirect contact (e.g. with a differential
circuit breaker). The electric cable wire size must take into
account the operating currents and length of the line to avoid
excessive voltage drops.
Avoid use of extension leads wound on drums. The power
cable must be suitable for frequent movements and with an
abrasion resistant sheath (e.g. type H07RN-F).
Before connecting the mortar mixer to the electrical mains,
ensure that all safety devices are fitted and are in perfect
condition, and check in particular that the hopper grid is secured
in place, that the extension in good condition and that the plugs
and sockets are not wet.
Connect the mortar mixer socket on the electrical panel to the
mains.

10.2 AIR CONNECTION
FOR SPRAYING ONLY
In the case of compressors with outputs up to 400 l/min connect
the air delivery directly to the jet as in the case of control of the
machine by means of the incorporated pneumatic control (see
par.4.2).
The machine can be controlled by means of the electric pendant
control supplied. This solution is also possible for compressors
with output below 400 l/min.
