Flomix Setup

When using Flowmix for the first time and every subsequent use :

• Place the tub under the discharge tube
• Connect the power cable and switch the control panel on
• Connect the water
• Run the mixer to check the direction is OK
• Run the mixer
• Open the butterfly valve on the silo
• Adjust the water as required

The mixer works mostly off a timed run started by pressing the green button. It will stop automatically after the set time. Please ensure there is sufficient space in the tub to ensure the mixer outlet does not choke.

All deliveries are assumed to be 20 tonnes unless previously agreed. It is the responsibility of the site to order within the quantities of an official order. Any material ordered beyond that will be expected to be paid through amendments or re-issue of the original order.

Your silo will require to be checked regularly for the level of mortar within it. This will be done either

• Manually by generally tapping the side
• By means of a low-level indicator
• A digital read-out monitor silo

How to carry this out will be part of the operator training.

You can also monitor this by easily calculating your tub use. Each 0.25m3 tub contains approx. 450kg of mortar per 1/3 tub.

It is the responsibility of the site to monitor these levels through their trained operator(s). Any material over-ordered cannot be credited and may incur disposal charges.

Continual monitoring of site practices will be done during routine maintenance and extra training can be provided by an arrangement which may be chargeable.

Setting The Site Up For Flomix

Site Requirements:

• Site Survey
• The Support Base
• Electrical Requirements
• Water Requirements

Site Survey

Stoneyford Concrete will carry out a site survey at an early stage of the contract to discuss and advise the most suitable location for placing the silo and to ensure that access for all placement and delivery vehicles are safe and suitable.

Comprehensive method statements and risk assessments are available for the placing procedure.

This service is included in the agreed material price. Servicing is carried out in line with manufacturer’s recommendations.

Silos cannot be provided to sites that do not comply with these requirements.

Support Base

A 3.0m x3.0m meter base is required in 35 Newton concrete 125mm thick (This will support a minimum 35 tonnes). The base must be constructed on a well-compacted aggregate sub base.

Silos will not be supplied unless above instructions are carried out.

Flomix mortar will advise a location of silo so that access for the delivery vehicle is safe and suitable.

In Addition:

• No movement of the silo must be carried out after placement without the permission of Stoneyford Conctere.
• Access to the silo must be maintained at all times and controlled by the site.
• The silo measurers 7.2 meters from the top of the foundation to the top of the silo,
• The site is responsible to provide safe access for deliveries and collections and all signage relating to that.

Electrical Requirements

Single Phase Mains 

The connection from the mains requires a 32A single phase 3 pin industrial socket which must be provided from a 32A motor rated MCB type C or D. The electrical supply must be protected by a 30mA RCD exclusively for the silo.

Generator 

Where no power is available a generator with a minimum capacity of 13 kVA (Fitted with a 16A 5 pin industrial socket from a 16A motor rated MCB. type C or D) is also sufficient to run the silo. Failure to do this will result in costly repairs to the electrical components of the control panel. Likewise, the generator must be started before the control panel isolator is switched on.

NOTE: All installations must be installed to be current IEE Regulation requirements for electrical installations (BS7671:2001) with attention being paid to the special location section relating to construction sites – section 604.

Water Requirements

A standard 1/2″ tap located within 5 meters of the silo is required and the integral water pump on the control panel will provide the necessary pressure for the mixing unit. If the direct pressure from the mains supply is sufficient it can be fed via a 25mm hose.

Where poor pressure is experienced a 60-litre storage barrel controlled by a ball cock can be fitted to provide a steady flow of clean water.

Silos can be run off a browser. Our representative can advise of this and the relevant connections.
