SITE REQUIREMENTS

Site survey

Hugh King & Co 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 is safe and suitable. No silo will be placed without this happening. 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.

The Base

The customer should ensure a 3 x 3 metre level base is constructed from 35N 150mm thick concrete and designed to support a minimum of 35 tonnes. The area must be free from the affects of running water and erosion. This construction is the responsibility of the customer but full advice and detailed drawings are available if required, especially if more than 1 silo is being placed. In addition no movement of the silo must be carried after placement without the

permission of Hugh King & Co. access to the silo must be maintained at all times in areas controlled

by site the silo measures 7.2 metres 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

3 phase mains

The silo arrives ready to be connected to an industrial 3 phase 5 pole switched socket provided by the site. This socket must be 16A 5 pin weather proof (supplied from a 16A 3 phase motor rated MCB type C or D). The electrical supply to the silo must also be protected by a 30mA RCD exclusively for the silo. This should be placed within 5 metres of the silo legs. The link cable, plus and socket should be of a suitable rating and mechanically protected (SY type). The plug and socket should have an IP rating of no less than 67 to prevent water ingress. It is the responsibility of site to provide these items and ensure they are protected from damage and the elements when not in use.

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. 3 phase is always recommended so check for the availability of single phase if there is no other option.

Generator

Where no power is available a 3 phase generator with a minimum capacity of 12 kVA (fitted with a 16A 5 pin industrial socket from a 16A 3 phase motor rated MCB. type C or D) is also sufficient to run the silo. It is essential when this is used the control panel isolator is switched off before the generator is shut down. Failure to do this will result in costly repairs to the electric 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 current IEE Regulation Requirements for Electrical Installations (BS7671:2001) with attention being paid to the special location section relating to construction sites – section 604.

Your main contact for all electrical matters is David McClelland 07766737601

Water requirements

A standard ½” tap located within 5 metres 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 bowser. Our representative can advise of this and the relevant connections.

SITE SET-UP

Ordering

All orders can be placed with Hugh King & Co offices on 01294 557515 or with your agreed contact. Please allow up to 72 hours for delivery. Every effort will be made to make delivery within this time scale but cannot be guaranteed.

Delivery Your silo will usually arrive containing 14 tonnes of material and will be refilled by tanker when required with 20 tonne loads.

To prepare for delivery there should be:-

unobstructed access to the silo at all times a hard level surface capable of carrying a gross weight of 40 tonnes headroom of 4.2 metres minimum width of 3 metres minimal delay after conforming to site rules

All unreasonable delays will be chargeable under the terms and conditions of the contract.

Re-ordering

Please allow 72 hours for delivery of your re-order of mortar. Deliveries within this time are not guaranteed. When re-ordering provide the office or representative with your site location your silo no eg:- K2219 your name and contact no day required any changes to the site set-up

All deliveries are assumed to be 20 tonnes unless previously agreed. It is the responsibility of site to order within the quantities of an official order. Any material ordered beyond that will be expected to be paid for through an amendment 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 gently 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. 340 kg of mortar so 10 tubs is approx. 3.4 tonnes used. It is the responsibility of site to monitor these levels through their trained operator(s). Any material over-ordered cannot be credited and may incur disposal charges.

Training

All relevant personnel will be trained by our Engineers. A Training Certificate will be issued to all those trained. Only these authorised individuals should operate a silo to ensure safe and efficient working practices. The full induction procedure covers mixing operations cleaning, daily and weekly safety and maintenance optimising water levels to suit site conditions fault diagnosis

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

DAILY USE

The silo should not be used until it is fully commissioned and operators training certificates issued.

The following is a reminder/summary of the full operating instructions that form the induction procedure.

Start-up

When using for the first time and every subsequent use place the tub under the discharge tube connect 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.

Daily Cleaning At the end of the day and before collection you must close the butterfly valve on the silo run out all the remaining material in the mixer run mixer empty for approx 5 minutes until clean water is discharged disconnect the water and remove the control panel to overnight store

Weekly Cleaning This procedure is essential to avoid repair bills carry out the daily cleaning procedure isolate from the power source remove the front mixing tube and screw clean thoroughly reassemble to keep dry

THESE PROCEDURES MUST BE FOLLOWED THOROUGHLY TO AVOID SEVERE DAMAGE TO COMPONENTS

CONTROL PANELS Your silo will be fitted with one of the two options – here is an outline guide reminder – for 3 phase RED sockets & plugs for single phase BLUE sockets and plugs

THE CONTROL PANEL MUST BE KEPT IN WARM, DRY CONDITIONS OVERNIGHT OR WHEN NOT IN USE - ANY

REPAIRS TO CONTROL PANELS DAMAGED BY FROST WILL BE CHARGEABLE.

PREVENTION IS THE KEY AS THESE REPAIRS ARE VERY

EXPENSIVE.

Cold Conditions Freezing water can cause serious damage to the panel and fittings and serious downtime on site. In addition to storing the panel in a frost free environment when not in use, also turn off the water supply uncouple the water supply pipe uncouple the pipe from the mixing chamber open the drain taps turn the control switch to brush position drain the water completely

Warm Weather / Lime Mixes With warm weather and / or lime mixes material can start to set if left for 30 minutes or more. This will overload the motor and cause problems when used again. To prevent this close the butterfly valve and run all the material out of the mixer each time it runs. Notes report all damage or changes to the silos immediately follow the procedures to ensure smooth running work with your contact to avoid chargeable repair

Following these steps and with trained staff, you will enjoy perfect mortar every mix.
