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.
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. If the voltage is different but in the same range, see section 2.7.
Amps: the actual supply must be capable of supplying the required amps. It should be fused at the
next available fuse size equal to or greater than the amps on the rating label.
A supply cable is fitted to 200-240V models, but may not be to 110-120V models. In there is no
cable, remove the back panel and connect a suitably rated cable to the internal terminals.
Either wire the supply cable directly to an isolator or fit it with a line plug. The plug or isolator
should be within easy reach of the operator to permit quick disconnection of the power.
For operator safety the supply MUST incorporate an earth (ground).

Voltage Level
Check the furnace rating label voltage. If the actual supply is not the same as the voltage on the
label, then the controller power limit should be adjusted.
If the actual voltage is higher than the label voltage, then read section 4.15 before switching on.
Either switch on and immediately reduce the setpoint to zero to prevent heating, or follow the
instructions in section 4.15 as quickly as possible. Heating with too high a power limit can burn
out the heating elements or blow a fuse.
If the actual voltage is lower than the label voltage, then the furnace is safe but underpowered. To
regain full power, adjust the power limit as explained in section 4.15.
