2.0 I NSTALLATION
2.1 Unpacking & Handling
When unpacking or handling the furnace always lift it by its base. Never lift it by the door. Use
two people to unpack and carry the furnace.
Carefully remove any packing material from the furnace chamber. Avoid damaging the
surrounding insulation when removing packing materials.
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 non-
inflammable surface that is resistant to accidental spillage of hot materials.
Ensure that there is free space of at least 50mm around the furnace. Do not obstruct any of the case
vents: they are needed to keep the controls and the case exterior cool.
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 Chimney
The chimney is a short length of ceramic tubing. If it is supplied unfitted, then fit it through the
hole in the top of the furnace case.
If the furnace is to be used to heat substances that emit fumes, then a fume extraction duct of about
150mm inlet diameter may be placed directly above the chimney outlet. Do not attempt make a
sealed connection to the furnace chimney as this causes excessive airflow through the chamber and
results in poor temperature uniformity.
2.4 Hearth
The chamber floor (hearth) is supplied with a ceramic tile. This may already be in position in the
chamber. If it is packed separately, unwrap it and place it carefully on the chamber floor.
2.5 Door Vents
There is a plate fixed to the inner door panel (door plug carrier), accessible by removing the door
insulation piece. This can be positioned to open up holes in the inner door, to allow an increased
air flow in the chamber. Decide on the required position and fix the plate accordingly (see section
5.7).
2.6 Electrical Connections
Connection by a qualified electrician is recommended.
The furnace requires a single-phase A.C. supply with earth (ground), which may be Live to Neutral
non-reversible (polarised), Live to Neutral reversible (non-polarised), or Live to Live.
CONNECTION DETAILS supply type
Supply Terminal label Cable colour Live-Neutral Reversible or Live-Live
1-phase L Brown To live to either power conductor
N Blue To neutral to the other power conductor
PE Green/Yellow To earth (ground) to earth (ground)
Check the following before connection, by reference to the furnace rating label.
Voltage range: the voltage on the label and the actual supply voltage should be in the same range –
either the range 200-240V or the range 100-120V. The furnace must not be connected to the wrong
range.
