SAFETY FEATURES
In this section the word “user” is to be interpreted as any person with access to or responsibility
for the ABF 8/28 and its ancillary equipment.
1.0 SYMBOLS & WARNINGS
1.1 Switches and Lights
1.2 Warning Symbols
1.3 Access to the Plenum Chamber
Soot can accumulate in the airway following the after-burner, giving rise to fire risk.
There is a plenum chamber with removable panels to give access to cleaning; see section 4.2.
The user is responsible for maintaining a clean plenum chamber, and also for regular cleaning of
the chimney and the external flue or ducting system.
1.4 Maintenance or Dismantling
The user should read the warning on refractory fibrous insulation, given in section 4.0, before
undertaking any work involving exposure to the internal insulation material.
The user should disconnect the equipment from the electrical supply before removing panels to
access the electrical connections and control equipment.

2.0 ABF INSTALLATION
Photo 2.1 - fastening the
chimney
Photo 2.2 - replacing the
panel
Photo 2.3 - screws
2.1 Tools Required
10mm spanner, 12mm spanner, cross point screwdriver, flat blade screwdriver.
2.2 Unpacking, Handling & Siting
When unpacking and moving the ABF always lift it by its base; never lift it by the door or any
other protruding part.
Remove any packing material from the chamber before use.
NOTE: This product contains Refractory Ceramic Fibre (better described as Alumino Silicate
Wool) for precautions and advice in handling this material see the ‘Repairs and Replacements’
section.
Install the ABF 8/28 in a well ventilated room, ideally away from sources of dust. The surface on
which the equipment is mounted should be resistant to accidental spillage of hot materials and
must not be inflammable. The surface should be stable and not subject to movement or vibration.
If the optional metal stand is supplied, this is best placed on a solid (concrete) floor.
The height of the mounting surface is important to avoid operator strain when loading and
unloading samples. A surface height of about 600mm is recommended to give a sample loading
height of about 960mm.
Ensure that there is free space around the ABF. Do not obstruct any of the vents in the case: they
are needed to keep the controls and the case exterior cool.
Ensure that the ABF is placed in such a way that it can be quickly switched off or disconnected
from the electrical supply - see below.
2.3 Fitting the Chimney
- Remove the split chimney panel (photo 2.2).
- Fasten the chimney to the top of the ABF using the screws provided (photo 2.1 & 2.3).
- Replace the split chimney panel (photo 2.2).

2.4 Ducting
The chimney must either be placed under a powered exhaust hood, or connected directly to a
76mm duct (not supplied) to the outside of the building; any such duct must NOT have powered
extraction.
The fumes should be ducted by either of the above methods to at least 1m above the level of the
building.
Rules for ducting:
Ducting diameter must be 76mm or more. Ducting must be 76mm where it connects to
the chimney.
Ducting length must not exceed 3m for 76mm diameter; for longer lengths consult a
ducting engineer.
Flexible ducting, if used, must be suitable for exhaust gas extraction.
If an extraction fan is fitted an extraction hood is required with free flow of air around the
chimney.
Do not connect more than one unit to a single duct. Exception: fanned duct with hoods.
