Technical data

Refer to Figs. 8, 9, 10 and 11.

10.1 Mains Supply 230V ~ 50Hz 140 watts. External Fuse 3A.

Internal Fuses: 2A Slow (F1), 1A Fast (F2). Both 20mm long.

10.2 Mains cable. PVC insulated 0.75mm (24 x 0.20mm) to

BS 6500 Table 16. The mains cable must be connected into

terminal X1, marked L (brown or red lead), N (blue or black lead),

and the earth cable fixed to the earth bracket at the top of the

electrical box, using a screw and cup washer. Ensure the earth

cable is longer than the other two cables so that it will not be

taut, should the mains cable be pulled.

appliance with at least 3mm contact separation in both poles.

10.5 If a room thermostat and/or frost thermostat is to be fitted,

refer to Fig.10. These must be suitable for mains voltage

operation.

10.6 A facia mounted twin channel digital programmer is

available as an optional extra. Instructions are suppled with the
