NSTALLATION
2.1
Unpacking & Handling
Lift the unit 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 oven where possible. Remove
any packing material from the inner chamber before use, and locate the shelves as required.
Larger models: the unit may be lifted by a fork lift truck from the front or back.
2.2
Siting & Setting Up
Place the oven on a level surface. If overtemperature protection is not fitted, ensure that the unit
can be directly observed.
Ensure that there is free space around the oven. Ensure that any vents in the oven are not
obscured.
Ensure that the oven is placed in such a way that it can be quickly switched off or disconnected
from the electrical supply - see below.
2.3
Electrical Connections
Connection by a qualified electrician is recommended.
All ovens 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. The 450 litre models
and above may be ordered for three phase supply with neutral (e.g. 380/220V) or for three phase
without neutral (delta).
Check the oven 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. A
table of the most common fuse ratings is also given in section 8.1 of this manual. Where a supply
cable is present there are internal supply fuses; customer fusing is preferred but not essential.
Oven with supply cable: either wire directly to an isolator or fitted with a line plug.
Oven without supply cable: a permanent connection to a fused and isolated supply should be made
to the internal terminals after temporary removal of the 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.
The supply MUST incorporate an earth (ground).
