2.0 I NSTALLATION
2.1 Unpacking & Handling
Laboratory Models. When unpacking or moving the furnace always lift it by its base. Never lift it
by the door. Use two people to carry the furnace. Remove any packing material from the door gear
and furnace chamber before use.
Industrial Models. Use a fork lift or pallet truck to position the furnace on a level floor.
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.
2.2 Siting
Place the furnace in a well ventilated area, away from other sources of heat, and on a surface
which is resistant to accidental spillage of hot materials.
Do not mount the furnace on an
inflammable surface.
Ensure that there is free space around the furnace. Do not obstruct any of the vents in the control
section: they are needed to keep the controls cool.
Ensure that the furnace is placed in such a way that it can be quickly switched off or disconnected
from the electrical supply - see below.
2.3 Setting Up
The furnace is supplied with the hearth tiles supported in place by a timber batten or steel plate
held by a jacking bolt fixed through the roof chimney hole. The chimney is supplied separately.
For the industrial models the door counterbalance weights are also supplied separately.
Laboratory models. Remove the bands holding the frame to the top of the furnace case. Withdraw
the bracket with the jacking rod assembly. Remove the steel plate from the hearth tile.
Fit the supplied furnace chimney through the roof hole.
Industrial models. To remove, take off the roof panel and unscrew the bracket complete with the
jacking rod assembly.
Fit the furnace chimney before replacing the roof panel.
Fit the door counterbalance weights to the door shaft such that the locking screws lock into the
countersunk holes. Note that one of the weights has a flat surface on the boss opposite the locking
screw. This weight goes on the side by the limit switch assembly such that the plunger of the
switch is depressed when the door is opened.
2.4 Fume Removal
If the furnace is to be used to heat substances which emit fumes, then a fume extraction duct of
about 150mm inlet diameter may be placed directly above the chimney outlet.
Do not make a
sealed connection to the furnace chimney as this causes excessive airflow through the chamber and
gives poor temperature uniformity.
