2.0 I NSTALLATION
2.1 Unpacking & Handling
When unpacking or moving the furnace always lift it by its base, not by any protruding fittings.
Use two people to carry the furnace where possible. Remove all packing material.
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 room: positive ventilation is recommended. See the warnings
in sections 1.3 and 1.4.
Site the furnace away from other sources of heat, 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 Fitting the Heating Elements
The Silicon Carbide elements are VERY FRAGILE and are packed separately. Fit them according to
the instructions in section 5.6.
2.4 Telescope
The telescope and its trunion arm are packed separately, and should be attached to the front of the
furnace.
2.5 Electrical Connections
Connection by a qualified electrician is recommended.
The furnace requires a single-phase A.C. supply with earth (ground). The supply may be Live to
Neutral non-reversible, Live to Neutral with reversible plug, or Live to Live.
Check the furnace rating label before connection. The supply voltage should agree with the voltage
on the label, and the supply capacity should be sufficient for the amperage on the label.
The supply should be fused at the next size equal to or higher than the amperage on the label. See
section 8.1 for fuse rating data. Internal supply fuses are only fitted if a supply cable is fitted;
customer fusing is essential.
Furnace with supply cable: either wire directly to an isolator or fit with a line plug.
Furnace without supply cable: a permanent connection to a fused and isolated supply should be
made to the internal terminals after temporary removal of the furnace back panel.
Connection by line plug: the plug should be within reach of the operator, and should be quickly
removable. Connection to isolating switch: this should operate on both conductors (single phase)
or on all live conductors (three phase), and should be within reach of the operator.
Single phase: connect the supply as follows:
supply type
Cable colour Terminal
label Live-Neutral Reversible or Live-Live
Brown L to live to either power conductor
Blue N to neutral to the other power conductor
Green/Yellow PE to earth (ground) to earth (ground)
