IMER INTERNATIONAL S.p.A.
IMER MORTAR MIXERS
- Before using the mortar mixer, ensure that it is
fitted with all safety devices.
- Never insert parts of the body and/or tools in the
hopper .
All current standards governing accident prevention and safety
devices must be observed in the workplace.
Take care when handling bags of material, to avoid sprays which
may come into contact with the eyes or other parts of the body.
Wear safety goggles and gloves. Avoid the dispersion of dust
which may be inhaled. Always wear a mouth and nose protection
mask during use.
- Never use the machine in areas subject to the risk of
explosion/fires or in underground installations.
The mortar mixer is not equipped with a lighting system and
therefore the workplace must be fitted with adequate lighting.
The power lines must be laid to prevent any possible damage.
Never place the mortar mixer on electric power cables.
Ensure that the electrical connection is protected against the risk
of water penetration in connectors. Use exclusively connectors
and couplings equipped with water spray protection.
- Never use inadequate or provisional electric lines; if in doubt
consult specialist personnel for assistance.
- Repairs to the electrical circuit must be performed exclusively
by specialised personnel. Disconnect the machine from the power
supply before performing maintenance or repairs.
-Avoid contact of electric wires with movable and/or moving
parts of the machine to avoid injury from contact with live metal
parts
.
6. ELECTRICAL SAFETY
The SMALL 50 mortar mixer is constructed according to standard EN
60204-1, with protection against water sprays and protection against
overload and power failure.
The mortar mixer must be connected to the earthing circuit.
- Caution ! Keep hands away from the rollers when
turning to avoid the risk of fingers becoming trapped.
- IMER COMPRESSORS code no.1107546
The air delivered by the compressor to the spray jet via a rubber
hose is used to spray the pumped material. Compressors with
different air flow rates can be applied on the machine: from 180
l/min to 600 l/min of air output. The selection of the type of
compressor to be used is based on the type of material handled
and the type of application. In general, the greater the air flow
rate, the finer the material spray delivered.
The 180 l/min compressor is suitable for most products which,
after spraying on walls require manual distribution (thick
applications: plaster, grouting, finishing mortar etc...). A
compressor with greater output is required for all products, which,
once sprayed uniformly onto the walls, do not need special
spreading operations, or which are only smoothed (thin layer
applications: levelling products, colours, some finishing mortars,
waterproofing agents etc.).
IMER code no.1107546, is an autonomous compressor. It is
connected to the site panel and the pneumatic circuit of the
machine.
- Caution ! For installation, connections, operation
and maintenance, refer to the compressor instruction
manual.
- This compressor is connected directly to the site
mains electrical panel.
This enables machine start-up when the air line is open and
shutdown when it is closed. The compressor is equipped with
an auto-shutdown system, overload cut-out, and main switch,
which lights up when the unit is powered.
Maintenance: Check the air filters weekly, clean or replace when
necessary, above all if working in excessively dusty
environments (see compressor operation and maintenance
manual).
It is positioned in the vicinity of the mortar mixer and connected
directly to the spray jet hose.
In this case the machine is turned on and off from the jet position,
using the remote control supplied with the mortar mixer, or the
optional radio control.
- RADIO CONTROL code no.1107518
Enables remote control of machine start-up/shutdown with
electrical cable connections.
The receiver is installed in the electrical panel.
The receiver is extremely practical; it can be held in the hand,
pocket or fixed to the spray jet, outlet or other element by means
of magnets. To turn on the machine, press ON, and to shut down
press OFF.
- Caution ! Protect the unit from water jets; it must
never get wet.
- PRESSURE GAUGE code no. 1107512
This is a control instrument used to read pressure levels in the
material hose lines.
For example: in the case of using traditional mortar at the maximum
flow rate of 100 on the panel display, and if pressure exceeds
15 bar (maximum pump pressure). To prevent tripping of the
machine protection devices, simply reduce the material flow rate
by pressing the pushbutton (-) on the electrical panel, until the
value falls below 15 bar.
