STARTING-UP
The procedures for starting-up the machine are described in the following
paragraph.
Positioning
Position the machine on a flat and stable base
and make sure that it cannot move by using the
brakes on the wheels.
Danger of being hurt!
The brakes on the wheels must be locked when using the
machine to give it sufficient stability.
Check that all switches, including the switch for adjusting the
direction of rotation of the machine and especially the main
switch of the machine, are deactivated before fixing the single
parts.
Electrical connection
Make sure that the fuses and switches cabinet in the building
yard is equipped with a grounded switch and a 25 A safety
device.
In addition, it is necessary to make sure that the power supply
is stable and that there are no possible rapid fluctuations of
tension. If this cannot be guaranteed, MALTECH forbids the
use of the machine and does not offer any guarantee for the
electrical parts of the machine.
The machine is equipped with a central supplier of
current (A). The entire machine is supplied electrically
thanks to the connection to this plug.

Water connection
Two water connections have been envisaged
on the machine.
The main connection (1) supplies the water
needed for mixing.
The secondary connection (2) is for cleaning
the machine.
The machine is equipped with a water pump for setting sufficient pressure,
independent of the pressure of the water supply connection.
A rubber hose (at least 10 bars) at least ¾“ in diameter must be
used as a connecting hose. It is necessary to check the
compatibility of the attachments to the hose and the machine
before connecting the hose. Unsuitable connections must be
replaced by suitable ones.
A filter to avoid contamination must be installed
at the entrance of the water. The filter must be
cleaned regularly and replaced if damaged.
In the case of particularly dirty water we also recommend
cleaning the filter several times during the day.
Damaging the machine!
Damage because of particles of dirt can occur if the filter is not
used. Inobservance forfeits any possible guarantee.
Connect the hose for the water supply (B) of
the machine to an external tap and expel
the air. To do this it is necessary to leave the
unloading valve open until there are no
bubbles left in the hose.
The pressure of the water entering must be at least 3 bars. If this
amount of pressure is not guaranteed (check the plant water
pressure (A)), it is necessary to use an overpressure pump with
the following characteristics between the water input and the
machine:
xMaximum flow pressure (water column 42 m)
xMaximum capacity 45 l/Min.
