2.1 Unpacking & Handling
When unpacking or moving the furnace always lift it by its base. Never lift it by the door or the
side panel. The furnace contains a transformer and is heavy: use two or more people to carry it.
Remove any packing material from the door gear and from inside the furnace chamber. Close the
door with care to prevent any damage to insulation surfaces.
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 & Setting Up
Place the furnace in a well ventilated room, 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. Do not mount the furnace where radiated heat from an open door could cause
damage.
Ensure that there is at least 75mm of free space around the furnace, and preferably 1.5m above. Do
not obstruct any of the vents in the case, or leave objects of any kind on the top surface. In
particular, the cooling fans in the case must not be obstructed.
If the furnace is to be used in a process which could liberate hazardous gases, then it should be
installed together with a suitable fume extraction system. A direct connection to the furnace
chimney should not be made.
Ensure that the furnace is placed in such a way that it can be quickly switched off or disconnected
from the electrical supply.
2.3 Fitting the Heating Elements
Wear eye protection when handling the heating elements. See the warning in section 5.8.
