FIG. 24 ROUTING OF ELECTRICAL WIRING
Following the pump manufacturer's instructions connect the
pump supply wires to terminals marked PUMP L,N, ' '-on the
boiler terminal block. Route the cable through the plastic bush in
the rear of the control box as illustrated in FIG. 24 and secure,
using the cable clamp.
Route a four core cable through the plastic bush in the rear of
the control box and the cable clamp as illustrated in FIG. 24 and
connect it to the boiler input terminals as follows:—
Fully Pumped Systems.
Permanent live to terminal marked MAINS 'L'.
Neutral to terminal marked MAINS 'N'.
Earth to terminal marked ' ' adjacent to cable clamp.
See NOTE.
Switched live from external controls to terminal marked
MAINS 'SwL'.
If there are no external controls fitted connect the SwL
terminal to permanent live in the junction box.

FITTING SIDE INFILL PANELS

If required, the gap between the casing sides and rear wall
can be closed off using the infill panels supplied.
Ensure the casing surface is FULLY CLEAN AND DRY.
Remove the protective backing paper from the adhesive strip
on the infill panel, carefully align and press into place,
applying FIRM EVEN pressure down the FULL LENGTH of
contact area between panel and case. If conditions are near
freezing, the boiler case should be warmed prior to
application of the infill panel.

Gravity Domestic Hot Water/Pumped Central
Heating Systems.
Switched live from external gravity domestic hot water control
circuit to terminal marked MAINS 'SwL'. Switched live from
external pumped central heating control circuit to terminal
marked MAINS 'L'. Neutral to terminal marked MAINS 'N'.
Earth to terminal marked ' ' adjacent to cable clamp. See
NOTE.
If there are no external controls fitted connect the SwL terminal
to permanent live in the junction box.
NOTE:
Ensure that the earth conductor is longer than the L, N & SwL
from the point of anchorage, so that the current carrying
conductors become taut before the earth conductor if cable is
pulled out of the cable clamp. When the wiring has been
completed close the control box and replace the securing screw.
