<strong>35</strong> REPLACING PRE-FITTED MAINS CABLE<br />
If it is necessary to use an alternative mains cable to the one<br />
pre-fitted then use the following guide.<br />
Replacement wiring should <strong>co</strong>mply with notes in Frame 33.<br />
1. Isolate the mains supply to the boiler.<br />
2. Remove the front panel. Refer to Frame 45.<br />
3. Swing the <strong>co</strong>ntrol box down into the service position.<br />
Refer to Frame 46.<br />
4. Remove the terminal block <strong>co</strong>ver to access the terminals<br />
for electrical <strong>co</strong>nnections.<br />
5. Remove the mains <strong>co</strong>ver to access the earth post.<br />
6. Remove the live and neutral wires from the terminal block.<br />
7. Remove the top nut from the earth post and remove the<br />
earth <strong>co</strong>nnection ring terminal from the post.<br />
8. Slacken the cable gland and withdraw the mains cable.<br />
9. Route replacement cable back through the cable gland<br />
and re-tighten to provide <strong>co</strong>rd anchorage.<br />
10. Connect the earth wire to the earth post by trapping the<br />
stripped end between the cupped and flat washer. Secure<br />
with nut provided.<br />
11. Connect the live and neutral wires to the terminal strip.<br />
When making the mains electrical <strong>co</strong>nnections to the<br />
boiler it is important that the wires are prepared in such a<br />
way that the earth <strong>co</strong>nductor is longer than the current<br />
carrying <strong>co</strong>nductors, such that if the <strong>co</strong>rd anchorage<br />
should slip, the current carrying <strong>co</strong>nductors be<strong>co</strong>me taut<br />
before the earthing <strong>co</strong>nductor.<br />
12. Re-fit the mains and terminal block <strong>co</strong>vers ensuring<br />
cables are located in the cable entry position.<br />
13. Swing the <strong>co</strong>ntrol box back up into the operating position<br />
and re-fit the front panel ensuring a good seal is made.<br />
