4.7.1 CASING REMOVAL (fig. 14)
To gain internal access to the appliance you must first
remove the casing, proceed as outlined below:
•
Locate and remove the 2-screws on the front underside
of the casing (C.)
•
Remove the 2 screws (B) located at the Left & Right of
the underside of the casing.
•
Lift the casing upward to disengage it from the top
locating hooks and then remove.
•
Store the casing and screws safely until required. Re-fit
in the reverse order.
4.7.2 APPLIANCE TERMINAL BLOCK
The appliance terminal block is located on the rear of the
control fascia. Remove the casing as described in 4.7.1.
Gently pull the control panel forwards and down. Locate
the terminal block cover (see fig. 15).
NOTE
The appliance comes with a factory fitted link (‘TA’) to
allow basic operation of the boiler once the circulating
pump has been connected. If it is anticipated that external
controls will be required please refer to the wiring diagrams
in section 8 for more detailed information.
4.7.3 CONNECTING THE MAINS (230V) INPUT (fig. 16)
Locate and remove the screws securing the terminal block
cover (230V). Pass the supply cable through the cable
anchorage point.
Connect the supply cable wires (LIVE, NEUTRAL, &
EARTH) to their corresponding terminals (L, N, & E) on the
appliance terminal block. When connecting the EARTH
wire, ensure that it’s left slightly longer that the others, this
will prevent strain on the EARTH wire should the cable
become taut.
4.7.4 CONNECTING THE PUMP (230V) OUTPUT (fig. 16)
Pass the pump cable through the cable anchorage point.
Connect the pump cable wires (LIVE, NEUTRAL, & EARTH)
to their corresponding terminals (L, N, & E) on the appliance
terminal block. When connecting the EARTH wire, ensure
that it’s left slightly longer that the others, this will prevent
strain on the EARTH wire should the cable become taut.
Do not remove the link wire unless additional external
controls are to be fitted (see section 8). The securing screw
on the cable anchorage should now be tightened. This
must be done before the control fascia is re-fitted in the
upright position. The appliance casing, screws, and lower
cover can now be re-fitted.
