The instructions for operating the temperature controller are given in a separate manual.

If the furnace is fitted with a time switch, see also the supplementary manual MS03.

3.1 Operating Cycle

If the furnace has an auxiliary heater, see also section 3.2.

The furnace is fitted with an Instrument switch. The switch cuts off power to the control circuit.

There is also a Heater switch which can be used to disconnect power to the elements.

Connect the furnace to the electrical supply.

Operate the instrument switch to activate the temperature controller. The controller becomes

illuminated and goes through a short test cycle. Adjust the temperature controller (see controller

manual).

Overtemperature option only. If the overtemperature controller has not yet been set as required, set

it and activate it according to the instructions in the appropriate manual.

Switch on the Heater switch, located on the instrument panel.

Unless a time switch is fitted and is off, the furnace starts to heat up. The Heat light(s) glow

steadily at first and then flash as the furnace approaches the desired temperature or a program

setpoint.

the same instrument switch as the main controller. Note that a time switch (if fitted) may not

switch off the auxiliary heater, depending on other options ordered.

Set the auxiliary heater's temperature controller after setting the main controller, as given in
