Installation, Operation and Maintenance Manual
Dalamatic Insertable Dust Collectors – Series DLM V
GENERAL SAFETY REQUIREMENTS
The collector should be stored as supplied. Only remove packaging to
install.
For the purposes of storage:
•Collector with specification for inside use = IP50.
•Collector with specification for outside use = IP54.
The dust collector should be used only when it is in a technically
acceptable condition. Regular maintenance, as set out in this
manual, is required to minimise technical failure. Third party supplied
components (for example motors) should be maintained according to
the manufacturer's instructions.
You should ensure any persons carrying out work on the supplied
equipment follow any relevant recognised standards/codes, have
received adequate training and are competent to do so. Areas requiring
a competent person include:
•Maintenance on any component identified as a potential ignition
source.
•Lifting and erection.
•Electrical installation, inspection and maintenance work.
•Pneumatic installation, inspection and maintenance work.
•Any access to internal classified potentially explosive atmospheres
where there may be a risk due to explosion.
During assembly/installation or dismantling of equipment, potential
ignition sources may occur that were not considered in the risk
assessment of the unit in operation (for example, grinding, welding
sparks, etc.)
You should use the dust collector in full accordance with the conditions
set out in the Order Acknowledgment and relevant Scope of Delivery.
Failure to do so may compromise product reliability, warranty and safety.
The Scope of Delivery is an integral part of the manual.
Other items of equipment, not supplied under the Scope of Delivery from
Donaldson, should be installed, operated and maintained according to
the documentation supplied with the respective equipment.
Any modification carried out on the 'as supplied' equipment may reduce
reliability and safety, and will nullify warranty; such actions fall outside
the responsibility of the original supplier.
Where necessary for safety, the dust collector is fitted with fixed guards.
Removal of these guards and any subsequent work should only be
carried out after adequate precaution is taken to ensure it is safe to do
so. All guards should be refitted before re-energising.
The access door requires tools to open. To avoid danger from rotating
fan impellor, ensure fan is isolated and allow sufficient time for fan to
become stationary.

Installation, Operation and Maintenance Manual
GENERAL SAFETY REQUIREMENTS
Compressed air is recommended for collectors that operate using
reverse jet cleaning. Alternative gases should be assessed before use
to ensure that explosive atmospheres are not introduced during media
cleaning.
Where the equipment supplied is suitable for working within a potentially
explosive atmosphere (as defined by Directive 94/9/EC) it will be
according to the categories and conditions marked on the collector
serial nameplate. You should ensure the equipment supplied by others
is also suitable. If no marking is given on the serial nameplate then
the supplied equipment is not suitable for use in potentially explosive
atmospheres.
Care should be taken to ensure that any potentially explosive atmosphere
is not present when performing operations that increase the risk of
ignition (opening of controller for adjustment or electrical repair for
example). Ensure the installation is always returned to its original state.
To reduce the risk of ignition when handling explosive or flammable
materials, it is important that the accumulation of flammable deposits
are prevented/removed, e.g. from within ducting etc.
If the collector is handling a potentially explosive dust or is placed in a
potentially explosive atmosphere, then all motors should be connected
to thermal protection devices to prevent them exceeding their maximum
surface temperature. All electrical equipment should comply with a
category according to all related National and Local Codes.
Where the dust being processed can ignite due to exothermic reaction,
including self ignition, the installation MUST be fitted with a suitable
explosion protection method (venting for example). The risk of ignition
can be minimised by avoiding the accumulation of dust layers with
regular cleaning.
Precautions, as set out in the Scope of Delivery, are used to minimise
the risk of ignition of any dust clouds contained within the dust collector.
The possibility of other ignition sources being introduced into the
collector during periods where any dust cloud may be present should
be minimised. Particular care should be taken to avoid introducing
glowing particles via the inlet ducting.
You should ensure that explosions are not allowed to propagate into the
dust collector (using suitable isolation devices) since pressures may be
generated leading to unsafe equipment rupture.
Where applicable, equipment connected to the dust collector (for
example, a cyclone) should be protected, using suitable isolation
devices, against the transfer of flame and pressure if, in the event of an
explosion initiating inside the dust collector, the connected equipment
is not capable of safely withstanding these effects.

GENERAL SAFETY REQUIREMENTS
It may be necessary to provide a facility to shut down the equipment in
the event of an explosion.
Part of the risk assessment on possible ignition sources for dust and
gas mixtures with very low MIE, has considered the electrostatic risk
from cone discharges. Here the basis of safety is based on using a
conductive bin, dusts with a median particle size of less than 400µm
and advising frequent emptying.
You may wish to consider the use of a sprinkler system when handling
explosive or flammable materials.
None of the fan assemblies can be considered to be a fully sealed
design, indeed most are arranged with either an open inlet or an open
outlet. For this reason, the internal and external atmospheres can be
considered the same in terms of any potentially hazardous classification.
Standard fan assemblies should not exceed 3000 rpm (50 Hz supply)
on systems fitted with an inverter drive.
The filtration media is suitable for filtering particulate only (and not gas).
Some applications are prone to risk of fire. This risk can be reduced by
regular pulse cleaning.
•Any extinguishing technique and material used must be suitable for
the flammable nature of the dust.
•A water sprinkler system can be fitted as a special option.
Materials handled by the dust collector may be hazardous (e.g. toxic).
Conduct a Risk Assessment to ensure correct technique is employed.
The dust collector should be cleaned and put into a safe condition prior
to decommissioning. All equipment decommissioning/removal is to be
executed in a manner consistent with applicable codes, regulations and
sound engineering practice.

Dalamatic Insertable Dust Collectors – Series DLM V
INSTALLATION
Where equipment is installed in a Potentially Explosive Atmosphere,
care should be taken not to locate or use the collector where external
ignition sources can be introduced, for example stray electric currents,
lightening, electromagnetic waves, ionising radiation, ultrasonic
waves.
When handling explosive or flammable materials and the risk of a fire is
high, then precautions such as fitting a sprinkler system and not locating
the collector in a zone 21/1 area should be considered.
When handling explosive or flammable materials the collector should be
located so as to avoid external heat sources, e.g. from nearby processes
or extreme direct sunlight.
The collector is not designed to support site-installed ducts,
interconnecting piping or electrical services. All ducts, piping or
electrical services must be adequately supported.
All external equipment connected to the outlet (e.g. ducting) should be
correctly sealed. This can be achieved by applying a continuous 5 mm
bead of sealing compound to the mounting surface, along each side
of the hole pattern. For non-Donaldson equipment please also check
supplier's IOM manual for any specific requirements.
Details of standard fan motor supply voltage are given in Table 8 (refer
to 'Specification' section).

(Note protective packing)
Horizontally inserted collectors are normally fitted
‘manifold up’ for ease of access and maintenance,
but where headroom is restricted they may be placed
‘manifold down’. The collector itself will operate with
equal efficiency in either position.
Under no circumstances
should the collector be
lifted as illustrated above
