FIG. 23 ROUTING OF ELECTRICAL WIRING
Following the pump manufacturer’s instructions connect the
pump supply wires to terminals marked PUMP LN on the
boiler terminal block. Route the cable through the plastic bush in
the rear of the control box as illustrated in FiG. 23 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. 23 and
connect it to the boiler input terminals as follows:
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.
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.
FITTING SIDE INFILL PANELS
If required, the gap between the casing sides and rear wall can
be closed off using the infill panels supplied.
Minimum or maximum rear boiler clearance is catered for by
turning the infill panel. Attach each infill panel to the rear of the
boiler using two pieces of magnetic strip (accessory pack G)
positioned as illustrated.
