INDEX

The equipment should be maintained in accordance with this manual, in order to ensure the best
performance is achieved throughout the life of the filter unit.
In all dusty environments ‘good housekeeping’ is essential to creating and maintaining a safe,
healthy environment. With potentially explosive dusts it is essential that all areas, and in particular
areas around any explosion vents, are dust-free to minimise the risk of secondary explosion in the
event of primary explosion within the equipment.
Regulation 9 of CoSHH – “Maintenance, examination and testing of control measures” requires that
the equipment is maintained in an efficient state. Hycontrol strongly recommend that all equipment
supplied should be subject to a thorough examination and test at intervals not exceeding 12 months.
The user has a legal obligation to operate the unit within the limits specified.
Hycontrol offers comprehensive Service and Maintenance Support contracts to ensure that the
statutory requirements of inspection and testing are met, with appropriate records kept and optimum
functionality ensured. Please contact Hycontrol on [phone] for further details.
Care should be taken during the emptying of waste collection bins and final waste disposal to avoid
possible secondary dust emission or contamination. It is recommended that respiratory protective
equipment be used - for further information consult B.S.4275:1974 RECOMMENDATIONS FOR
THE SELECTION AND USE OF RESPIRATORY PROTECTIVE EQUIPMENT.
1. INTRODUCTION
Any changes to the process and/or the dust being handled should be assessed to ensure that no
hazard is introduced and control over the contaminant is not compromised. Please contact Hycontrol
if in doubt.
The Hycontrol Hyvent dust collector and filter unit has been designed to form an integral part of
Hycontrol's advanced SHIELD and SHIELD Lite silo protection system (SPS). Please refer to other
manuals for further information on the other equipment supplied as part of the SPS. Please read this
manual carefully before using the Hyvent unit.
Any work carried out on the equipment - for example lifting, electrical or pneumatic connections -
should be carried out by competent persons.
Prior to putting the unit into service it is IMPERATIVE that a risk assessment is carried out to
ensure that all hazards are identified and suitable control measures put in place to reduce the
risk to a safe level.
It is recommended that this risk assessment uses the latest techniques and refers to the latest
relevant guidelines and legislation.
The unit should only be put into service if the risk assessment confirms it is safe to do so.
PLEASE NOTE:
Dust collectors must be used in accordance with the CoSHH regulations. For further information refer
to current Health & Safety executive guidance note EH40 "Occupational exposure limits" and
guidance note EH 44 "Dust in the work place: general principles of protection".
Where the unit is handling an explosive atmosphere or is located in a potentially explosive
atmosphere this will be advised in the quotation and a statement of such included in the declaration of
conformity. Please ensure that any work on the filter unit does not create additional ignition sources.
www.hycontrol.com 1

Pressure system regulations
The compressed air manifold falls within the Pressure Equipment Regulations 1999 and the EC
Pressure Equipment Directive (97/23/EC). Manifolds supplied are in accordance with the above
legislation and relevant information for safe operation is included on the nameplate attached to the
manifold. Please ensure that these limits are not exceeded.
Explosion prevention
Atmospheres that are considered explosive are covered by the Dangerous Substances and
Explosive Atmospheres Regulations 2002 (DSEAR) which implement two European Directives: the
safety aspects of the Chemical Agents Directive(a) 98/24/EC9 (CAD) and the Explosive
Atmospheres Directive 99/92/EC10 (ATEX 137).
Where the unit is handling an explosive atmosphere or is located in a potentially explosive
atmosphere this will be advised in the quotation and a statement of such included in the declaration of
conformity. The user has a legal obligation to operate the unit within the limits specified.
A pressure relief valve (PRV) is required if the maximum operating pressure can be exceeded with
the supply, and forms an integral part of Hycontrol’s silo protection systems. Please refer to separate
documentation for further information.
Please maintain the pressure equipment, including any supply lines, in accordance with the above
legislation.
Any additional items of equipment supplied by the user (out of scope of Hycontrol supply) should be
risk assessed and confirmed suitable prior to putting into service. This is particularly important when
considering if the items have or can generate ignition sources. Consideration should be given to all
components of a system.
If the unit is supplied with an explosion panel or flameless venting device, the unit should be
positioned such that the products of the explosion, flame and pressure (in the case of a vent panel)
and pressure (in the case of the flameless venting device) are directed to a safe area. Where the unit
is mounted onto a vessel that contains explosion protection, the user must ensure that the strength of
the unit supplied is not exceeded during the venting process.
Usage
The Hyvent is specifically designed for the handling of dry dusts in air and must not be used for any
other purpose. Users should always consult with Hycontrol concerning the application of the
equipment and the product being handled. The responsibility for the accuracy of information
concerning product or application always lies with the user.
Health & Safety
Before putting into service it is important that the complete assembly is risk assessed and only put
into service if this assessment concludes it is safe to do so. Consideration should be given to all
components of a system.
2. SUPPLY SERVICES REQUIRED
The unit requires an adequate supply (see below) of clean, dry and oil-free compressed air.
Contaminated air will cause malfunction and reduce the life-span of the filter media. We recommend
the fitting of a suitable moisture separator and regulator immediately prior to the manifold, ideally this
should have a facility to relieve the stored pressure from the manifold to assist maintenance.
Compressed air supply
www.hycontrol.com 2

Apply a suitable sealant for the application and working conditions (silicon is recommended) using
two beads, either side of the bolt holes, ensuring this will form a continuous seal with no gaps. Secure
the unit in place using suitable fixings (not supplied).
The supply pipe should be 1/2" nominal bore as a minimum. 3/4" nominal bore is recommended for
long pipe runs, due to the movement of the manifold as the lid is opened and closed. The connection
should allow for this.
The maximum manifold operating pressure will be indicated on the nameplate attached to the
manifold. Please ensure that this is not exceeded.
DC units input supply: 24 V DC
Maximum pressure: 6.5 barg
Electrical supply
The figures given are free air delivered (F.A.D) based on a pulse interval of 15 seconds, with a pulse
duration of 100 msecs. To ensure optimum cleaning the following pressures are recommended:
Any work carried out on the equipment should be carried out by competent persons and in
accordance with current legislation.
Note: The connection into the manifold is a 1” parallel threaded female fitting.
Consumption (approx.): 11.7 m³/hr
Operating pressure: 5.0 - 6.0 barg
AC units input supply: 230 V or 115 V AC
Note: See appendix for wiring diagram details. Please be advised that failure to use the correct
supply required can result in damage to the PCB and will invalidate the warranty.
3. INSTALLATION
Handling
All handling and lifting activities should be carried out by a competent person.
See handling document under appendix section for details of lifting points and lifting methods.
DO NOT lift the unit by means other than those recommended as this may result in a safety risk or
damage to the equipment. Lift using the lifting eyes on the unit ensuring that the two M12 bolts are in
position on the side of the cowl prior to the lift.
Installation and assembly
Please note: This unit must be installed in the vertical position. Do not install at an angle.
The unit is normally supplied fully assembled. Refer to Appendix for exploded diagram.
For units supplied with mounting spigots or flanges.
Remove the mounting spigot / flange from the assembled unit.
Weld the spigot / flange to the silo. After welding, degrease and paint the spigot with an appropriate
protective coating.
www.hycontrol.com 3

Prior to opening cowl, ensure that appropriate protective equipment is used. Minimum requirement is
a dust mask and gloves when the reusable metal core is present (3.5 m² cartridges).
Warning: Isolate the electrical and compressed air supplies and drain any stored compressed air
from the system prior to opening the cowl.
Supply connection
The compressed air supply should be suitable for the requirements – see compressed air supply
notes in Section 2 above and provide a means of isolating and discharging the stored pressure from
the manifold to assist maintenance.
All supply connections are to be made in accordance with the appropriate statutory requirements.
Refer to electrical supply notes in Section 2 above and the appendix for wiring diagrams. Failure to
make the connections correctly may result in damage to the controller and invalidate the warranty.
IMPORTANT: The controller complies with the Electro-Magnetic Compatibility (EMC) directive
as supplied. In order to retain compliance an electrical supply where the neutral is NOT earth
bonded is required. Failure to do this may result in the loss of compliance.
Cartridge installation
Any work carried out on the equipment should be carried out by competent persons and in
accordance with current legislation.
When removing and replacing elements, the following procedure must be adhered to:
Please ensure these bolts are refitted after the cowl has been lowered back into position.
Once the unit is secured in position, remove the temporary manifold protection bars.
Important Note: Before lifting the cowl assembly to gain access to the filter elements, first remove
the two M12 bolts positioned either side of the cowl near the front of the unit.
www.hycontrol.com 4
Ensure the sprung plunger is engaged fully through location hole in side
of cowl when in the open position.
Removal: Remove cowl securing bolts and tilt cowl backwards whilst
retaining hold of the cowl handle. Take care if the cowl is exposed to
high winds.
Tip - the plunger locates automatically if released and allowed to run on
the inside of the cowl during opening.
Loosen cartridge clamps and rotate to
allow cartridge removal. Pull out element
with metal core.
Note: 3.5 m² cartridges comprise 2 parts
- a metal core with top flange and a
pleated media cone with end caps.
Remove the metal core from the old
media cone and fit to a new media cone.
4.0 m² cartridges are one piece items for
complete replacement.

Check all control functions.
Check that all connections have been correctly made and that the appropriate power sources are
available.
It is IMPERATIVE that the unit is installed and adjusted to ensure that the stated airflow is not
exceeded - excessive air volumes can seriously affect filtration efficiency and element life.
Note: Unless otherwise specified, the cleaning control and manifold have been tested and confirmed
to be fully functional prior to despatch from Hycontrol. With the exception of power supply to the
controller and fan (if fitted) along with a compressed air supply to the manifold no other connections
are required.
4. OPERATION
General operating parameters
To complete installation, insert the complete element into the filter plate. Reposition the clamps and
tighten until the clamp bottoms on the spacer - DO NOT OVERTIGHTEN. Once the clamp is tight
against the spacer the cartridges are sealed and further tightening will only cause damage. Maximum
tightening torque is 22 Nm.
Whilst retaining hold of the cowl handle, release and secure plunger in withdrawn position and lower
the cowl. Please take care if the cowl is exposed to high winds. Fit the two M12 retaining bolts.
Commissioning
Any work carried out on the equipment should be carried out by competent persons.
Check that all packaging and protection materials are removed prior to start up. This can include
remote controls taped inside unit, protection around explosion relief panel, etc.
Ensure all cartridges are correctly fitted. Ensure access door is sealed.
We recommend commissioning of the unit is carried out by experienced and competent personnel.
Commissioning requires adjusting the system airflow to the design duty and taking static pressure
readings as a basis point for reference and future thorough examinations and tests.
DO NOT plug or make connections to the solenoid valve vent ports as this may inhibit the operation of
the valves.
It is important that the silo on which a filter unit is mounted is not overfilled, as this can cause blinding
and over-pressurisation. Transfer from lorry tanker to a silo must be correctly controlled to ensure that
excessive volumes of air are not introduced into the silo, this can cause premature deterioration of the
media.
The compressed air manifold has been designed and manufactured to the operating limits of
temperature and pressure as stated on the manifold data plate. The limits of temperature, in
particular the upper limit, are specific to the manifold fabrication and do not imply that all other
components associated with the manifold or dust collector are capable of operating at such
temperatures. If a unit is to be utilised in an operating temperature range other than that for which it
was originally intended. Please contact Hycontrol to ascertain suitability.
The cleaning controls are NOT preset at works to suit any specific application, although under
inspection these will normally be left set at approximately 100 millisecond duration and 15 second
interval. As no two applications are the same, filtering process must be monitored and the controls
adjusted to suit the particular application, as outlined in section 5.
www.hycontrol.com 5

The filter cleaning system should be adjusted to give an approximate average pressure differential
across the media of 100 mm w.g.
Use the following as a general indication:
Heavy dust load: short interval
Pressure differential
Interval is normally related to dust load.
Light dust load: long interval
Use the following as a general indication:
Heavy, free flowing dust: short duration
Ensure air and power supplies are connected as specified. Start the cleaning system prior to product
transfer / airflow into the silo. Allow the cleaning system to continue running for several minutes after
product transfer / airflow is complete (this will be operated automatically by the Hycontrol silo
protection system).
Duration is adjusted to suit the type and binding characteristics of the dust being handled,
generalised as Specific Gravity (SG) and stickiness.
Note: cleaning cycle adjustment requires access to an enclosure containing live terminals. Isolate
before opening and only return the power when needing to make the adjustments, taking
extreme care.
The cleaning cycle has two modes of adjustment: Duration and Interval.
Duration
Interval
Start up
Light, sticky dust: long duration
5. ADJUSTMENT OF THE CLEANING CYCLE
IT IS ESSENTIAL THAT THE CLEANING CYCLE IS MONITORED, PARTICULARLY DURING
THE FIRST WEEKS OF OPERATION, AND THAT ADJUSTMENT IS MADE TO ENSURE THAT
THE CLEANING CYCLE CONTINUES TO SUIT THE OPERATING CONDITIONS.
www.hycontrol.com 6
Note: The pressure test point is located
on the filter plate. In order to take test
readings open the cowl as described in
Section 3 above and insert a 1m length
of 6 mm O.D. tube into the test point.
Connect to a gauge after closing, secure
the cowl and resume operation.
Allow tube to drop over the front edge of
the filter plate.

6. MAINTENANCE AND SERVICE
- Measure and record pressure differential (if possible)
ALWAYS replace the locking device when the cowl is in the lowered position and fasten the lid with
two M12 bolts.
ALWAYS ensure that ALL sources of energy are isolated and locked off and that any retained
compressed air in the cleaning system is drained PRIOR to accessing the interior of the unit.
ALWAYS engage the locking plunger whenever cowl is in the raised position.
Routine inspection
- Check filter clamps and seals
Hycontrol offers comprehensive Service and Maintenance Support contracts which cover the
aforementioned requirements. Please contact Hycontrol for further information. Specific industries
and applications may require more frequent inspection. More information regarding such
applications can be obtained from the HSE or local authorities.
- Inspection of clean air compartment
- Test cleaning cycle of reverse air systems and mechanisms
Safety
The manifold should be inspected in line with the Pressure Equipment Regulations 1999 and the EC
Pressure Equipment Directive (97/23/EC) by a competent person.
- Measure and record static pressure (if possible)
- Record controller settings
Inspection and maintenance should be carried out by competent personnel. Appropriate dust mask,
respirator, and other personal protective equipment MUST be worn when accessing the dirty
(contaminated) section of a dust collector.
Maintenance access
If deliveries are infrequent i.e. less than 1 per week it is recommended that a cleaning cycle is run at
least once to operate the filter, thereby optimising the life of the filter cartridges and keeping fully
functional for when required. To ensure trouble-free operation and minimise the risk of unscheduled
stoppages it is advised that the following inspection be performed at least once every 6 months:
Should a manifold require pressure testing, this must be carried out hydrostatically in accordance
with the original specification. Manifolds MUST NEVER be tested with cleaning valves and other
equipment fitted. The manifold must be stripped and blanking plates fitted prior to testing.
- Check filter cartridges
- Measure and record system airflow volume (if possible)
Do not under any circumstances attempt to work in conditions where appropriate working
platforms and access have not been erected or where personal safety equipment appropriate
to the task in hand is not available.
Inspection of compressed gas equipment
Manifolds supplied are in accordance with the above legislation and relevant information for safe
operation and inspection is included on the nameplate attached to the manifold.
Venting filters may be fitted in positions without access walkways or ladders. It is imperative that no
effort is made to gain access to any part of a unit, or to carry out any maintenance operation, unless
correct and safe working conditions are established.
