INTRODUCTION H&S DISCLAIMER
This quick guide will show you how to connect,
start up and use the mortar mixer that comes
with your EuroMix silo.
Your silo will be set-up and checked by the
EuroMix technician before being handed over
to you for use. However, there are a few simple
things you can do to make sure the silo gives you
easy and trouble free mixing.
The most important thing you can do to help
keep the machine working is to always carry
out your daily and weekly clean. The cleaning
procedure is shown in this guide in detail, but if
you need any help or have any questions please
call your local plant.
During the winter months or if frost is at all likely,
please follow the cold weather working guide.
It is important that you protect the control panel
from frost damage as this will also prevent any
downtime from damaged equipment.
There is a fault diagnosis owchart at the back of
the guide which you should follow to resolve any
issues with the mixer.
Only trained operatives should operate this
equipment. The equipment requires to be
stripped and cleaned, and it is EXTREMELY
IMPORTANT that the machinery is
disconnected from the mains supply by fully
removing the supply plug before carrying out
any work on the machine.
It is the customers responsibility to ensure that
all sta operating a EuroMix Silo Station are
fully trained.
CPI EuroMix are happy to carry out training
free of charge, simply contact your local CPI
oce to book.

The isolator switch turns the electricity supply to the panel o.
Nothing will function whilst this switch is in the ‘O’ position. To
operate the mixer, this switch must be turned clockwise to the
‘On’ position.
To completely isolate the panel the power supply MUST be
disconnected by removing the mains supply.
To start the mixer operating, simply depress the green ‘On’
button. The mixer shaft will then start to turn, the water valve will
open and the water pump will operate.
You can tell if the machine is operating by checking the shaft is
rotating clockwise in the face of the outlet and the motor fan is
turning. Water should be coming out of the outlet of the mixer.
The mixer is operated on a timer and will stop automatically. You
can also stop it at any time by depressing the red ‘Stop’ button.
The buttons are clearly marked as shown below.

This switch must always be in the down position. If the
switch is in the up position, water will pass through the
panel and mixer and the ‘start’ and ‘stop’ buttons will not
function.
Note
Not all control panels will contain this switch.
There are multiple sockets on the panel – for the mixer
motor, vibrator and mains inlet. It is important that these
are all correctly connected. All cables should be visually
inspected before any connection is made.
Refer to the diagrams on pages 4 and 5 for a simple guide.

The silo requires a 3/4" water supply with a minimum ow
capacity of 900litres per hour at 2 BAR pressure. Some sites
may require a break tank to comply with local water Bylaws and
this can be supplied by CPI EuroMix on request.
The water supply can be provided by a water tank if there is
no mains supply to the site. The tank outlet must be placed a
minimum of 500mm above ground level, within 5mtrs of the silo
and equipped with a 3/4" outlet. An inline lter must be included
prior to the silo connection.
All CPI EuroMix silo equipment will be inspected and tested
prior to the commencement of the hire. A certicate showing
the results of the test will be issued for each piece of equipment.
It is the customer’s responsibility to ensure the equipment
is safe to use whilst on site and to ensure compliance
with the Use of Electricity at Work Regulations.
CPI will carry out subsequent tests on request. There is a
charge for this service.

Adjust the mortar to the required consistency by slowly turning
the black water tap. This can be found on the left hand side of
the combined panel, or inside the water panel on a split unit.
This adjustment will be carried out by the CPI EuroMix Service
Technician during the set-up process, but can be altered by the
user.
Be careful not to run the material too dry, as this could cause
the mixer to stall and the motor to trip the protection device.
The mixer operates on a timer. This timer will be adjusted during
the set-up of your CPI EuroMix silo to suit the size of your
mortar tubs.
The timer cannot be adjusted whilst the mixer is running and
should only be adjusted by a qualied person.
Always start the mixer with the product handle on the silo in the
shut position (horizontal).
When the mixer is running and water can be seen coming from
the mixer outlet, slowly open the product handle (move towards
the vertical).

CLEANING
Regular cleaning is essential to ensure continued
performance of the mixer. Wet mortar will set hard, so it is
important the mixer is emptied of material after each run of
tubs.
If the mixer is to be left for more than 30 minutes, slowly
close the product handle (down to horizontal) as the last
tub is completed. Let the mixer run for 20 seconds until
water comes from the outlet to ensure the mixer is clean.
Daily Cleaning
After running out the last tub of the day, close the product
handle on the silo (down to horizontal) and continue to run
the mixer. Water will come from the outlet. Once this water
is clear, run the mixer for a further 1 minute to ensure the
mixer is clean.
Weekly Cleaning
It is important that a thorough internal clean of the mixer
is completed at least once a week. A properly cleaned
machine will give long and reliable service. If the clean is
not carried out, the set mortar will cause accelerated wear
of the moving parts, and the machine will quickly cease to
operate.
The weekly clean will be demonstrated to you during
training. The steps are detailed below for reference.
1. Following your daily clean, disconnect the mains power and
fully isolate the machine
Note: Only trained and competent operatives should undertake this operation.
3. Withdraw the mixing screw and clean it thoroughly. If there
is excessive wear on the blades resulting in metal showing
through, call CPI EuroMix for a service
2. Remove the three nuts securing the mixing chamber to the
dry chamber with a 19mm spanner and remove the mixing
chamber
4. Clean any hard material that has gathered inside the mixing
chamber paying close attention to the discharge chute and
narrow rubber insert section

FROST PROTECTION
In cold weather the freezing water may seriously damage
the control panel and water ttings. It is therefore important
to ensure the panel is drained of all water and stored in a
frost free location overnight.
There are 8 simple steps to follow to protect the panel
from frost:

faults and help you keep your silo working. It is often the case that
the cause of a fault is a simple thing that can easily be rectied by
the operator.
Common faults include:
• Water hoses being connected incorrectly
• Power supply not being energised
• Water supply turned o at stop cock
• Silo product handle is in the closed position
• Electrical Safety Devices tripped
