NSTALLATION
2.1 Unpacking & Handling
When unpacking or moving the furnace always lift it by its base. The furnace contains a
transformer and is heavy: use two or more people to carry it. Some models may alternatively be
lifted by fitting lifting bolts to captive threads in the top of the case.
Remove any packing material.
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.
Ensure that there is free space around the furnace. Do not obstruct any of the vents in the case:
there are cooling fans in the case which must not be obstructed.
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
Fitting the Heating Elements
Wear eye protection when handling the heating elements. See the warning in section 5.6.
The Molybdenum Disilicide elements are EXCEPTIONALLY FRAGILE and are packed
