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 flowchart 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 staff operating a EuroMix Silo Station are fully trained. CPI EuroMix are happy to carry out training free of charge, simply contact your local CPI office to book.

The isolator switch turns the electricity supply to the panel off. Nothing will function whilst this switch is in the ‘Off’ 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.
NoteNot 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 flow 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 filter 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 certificate 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 qualified 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).

CLEANINGRegular 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

CPI EuroMix has produced a flow chart to help you diagnose 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 rectified by the operator.
Common faults include:
• Water hoses being connected incorrectly
• Power supply not being energised
• Water supply turned off at stop cock
• Silo product handle is in the closed position
• Electrical Safety Devices tripped
