1. 3 3 Filling the silo It is recommendable to remove the Spider Kit before filling and keep it outside the silo during the filling process to prevent it from being dented or damaged by the flow of pellets When the silo is full stand the kit on the pellets again in the centre of the silo if possible to ensure uniform suction over the entire surface IMPORTANT Correct functioning of the Spider Kit is only guaranteed if the wood pellets used as fuel comply with the DINplus quality standard Spider 3 4 Characteristics of the suction hose The Spider Kit for pellet removal and the pneumatic Kit Aspiration conveyor system working in combination are specially designed to function with an installation consisting of a plastic hose with an interior diameter of 50 mm This hose must also have a static electricity discharge system preferably a copper wire wound around its entire length This copper wire must be earthed at all the hose joints and ends Whatever the type of hose used it must be made of a suitable material for wood pellet transport and it must always have an interior diameter of 50 mm The following recommendations must also be complied with for correctly installing the Spider Kit in combination with the Kit Aspiration The maximum permitted hose length is 30 metres for flow from the main silo to the suction pot and 30 metres for return Bend angles of over 452 must be avoided wherever possible If these cannot be a
2. under any circumstances for damage caused by unsuitable erroneous or irrational use The Spider Kit is specifically designed for extracting 6 mm diameter pellets from a main silo and in combination with a pneumatic Kit Aspiration system conveying them to a Bioclass boiler reserve tank During installation or before any servicing the following indications must be observed to prevent personal injury or material damage e Remove all the packaging and check all the contents are included In the event of any doubt do not use the kit Contact your supplier Keep the packaging elements out of reach of children as they can be dangerous e Unplug the Spider Kit from the mains power supply before any servicing and during installation e For safety reasons another person should always be present when you access the pellet store If access to the store is difficult we recommend a second person waits outside to guarantee the safety of the person entering the store and who can let them out in case of hazard without endangering their own life e Before entering the pellet store ensure it is correctly ventilated there may be a lack of oxygen or concentration of unknown gases e Always wear a protective mask standard mask inside the pellet store for protection from airborne dust e Keep children away while you are working in the pellet store Ifthe pellet store is flooded there is no risk of contamination of the groundwater the soi
3. in length diameter and accumulation of volatile material and dust The pellet removal process described here may vary depending on the quality of the pellets used and on the particular silo design To ensure optimum uniform and durable functioning of the Spider removal system it is vital to use high quality wood pellets of 6 mm diameter compliant with the DINplus quality standard The Spider Kit used in combination with the Kit Aspiration can cover a silo surface area of up to 2 x 2 metres and can empty up to 80 of the silo s total volume capacity with suitable maintenance of the suction system filter It is also recommended to periodically inspect the silo emptying level ensuring the pellet distribution in the silo is as even as possible at all times as the amount of pellets removed in each cycle may vary greatly as indicated above meaning more removal cycles are sometimes needed to fill the tank When the silo is completely full the Spider Kit begins to form a cavity or a funnel effect sucking in the pellets from the top of the silo until it reaches the bottom On reaching the base of the silo the kit then moves towards the sides rotating in both directions The diagram below shows how the Spider Kit removes the pellets IMPORTANT Correct functioning of the Spider Kit can only be guaranteed if the wood pellets used comply with the DINplus quality standard IMPORTANT It is important t
4. pellets that remain in the hose installation emptying the hose and preventing obstruction when the next cycle begins In general we recommend adjusting the cycle time to its maximum setting by turning the adjustment screw clockwise as far as it will go If the installation settings are causing the Kit Aspiration to fill up some time before the end of each cycle we recommend reducing the cycle time for closer regulation so that it coincides with each filling of the suction pot It should also be observed that the amount of pellets taken in on each cycle may vary considerably depending on vacuum cleaner s filter maintenance pellet quality and the main silo emptying level at any given time and it is therefore preferable to set long cycle times The diagram below shows the functioning cycles governed by the Kit Aspiration electronic control Vacuum cleaner OFF Clockwise sense Spider OFF Counter clockwise sense IMPORTANT Thorough periodic maintenance of the Kit Aspiration s filter is vital to ensure sufficient uniform pellet suction flow NOTE If you choose to install the Spider Kit with a control and suction system other than the Kit Aspiration supplied by DOMUSA we recommend adjusting its functioning to the cycle types and times described above DOMUSA does not guarantee correct functioning of the kit if other cycle types and times are used Spider 4 2 Pellet removal 10 Pellets are a bulk product and they vary naturally
