2.0 Installation
2.1 Unpacking and Handling
Remove the shelves and runners from the packaging before attempting to move the
equipment.
When unpacking and handling the product, always lift it by its base. Do not use the door
or any other projecting cover or component to support the equipment when moving it.
Use two or more people to carry the product where possible.
Carefully remove any packing material from inside and around the product before use.
Avoid damaging the surrounding insulation when removing packing materials.
Locate the shelves and runners as required.
2.2 Siting and Setting Up
Place the product on a level surface in a well ventilated area.
Site away from other sources of heat and on a non-flammable surface that is resistant
to accidental spillage or hot materials.
The surface on which the equipment is mounted should be stable and not subject to
movement or vibrations.
The height of the mounting surface is important to avoid operator strain when loading
and unloading samples.
Unless otherwise stated elsewhere in this manual, ensure that there is at least 150
mm of free space around the back and sides of the product. Clear space is required
above the product to dissipate heat.
6

Ensure that the product is placed in such a way that it can be quickly switched off or
disconnected from the electrical supply.
Some models have protruding fan motor housings: these housings must be in an area
of good ventilation.
Under no circumstances should any objects be placed on top of the product.
Always ensure that any vents on the top of the product are clear of any
obstruction. Always ensure all cooling vents and cooling fans (if fitted) are
clear of any obstruction.
The ends of the runners should be inserted into the vertical
columns of holes simultaneously at the front and the back. The
bar should then be rotated through 90° in a downwards direction
to secure it in place. The shelves slide onto the runners such that
the spurs on the lower side of the shelf are under the bar at the
back; this prevents the shelf from tilting forwards when partially
withdrawn.
Do NOT use the oven floor as a shelf.

2.3 Electrical Connections
Connection by a qualified electrician is recommended.
All models covered by this manual may be ordered for single phase A.C. supply, which
may be Live to Neutral non-reversible, Live to Neutral reversible or Live to Live.
Check the product rating label before connection. The supply voltage should agree with
the voltage on the label and the supply capacity should be sufficient for the current on
the label.
The supply should be fused at the next size equal to, or higher than the current on the
label. A table of the most common fuse ratings is also given towards the back of this
manual. When the mains cable is factory fitted, internal fuses are also fitted. It is
essential that the operator ensures that the product is correctly fused.
Products with a factory fitted supply cable are designed to be wired directly to an
isolator or fitted with a line plug.
Products without a factory fitted supply cable require a permanent connection to a fused
and isolated supply. The product's electrical access panel should be temporarily
removed, and connections made to the internal terminals.
If the product is to be connected by line plug. The plug should be within reach of the
operator and should be easy to remove.
When connecting the product to an isolating switch ensure that both conductors (single
phase) or on all live conductors (three phase), and should be within reach of the
operator.
The supply MUST incorporate an earth (ground).
