Renewing the Internal Protection Fuse

CAUTION: First, read the section; 'Important safety information' at the start of this manual.

Isolate the electrical mains system supply before commencing installation.

Ensure all on/off power switches are set to their 'OFF' positions and the mains lead has been removed from the unit's power socket.

1Using a small thin-bladed screwdriver, remove the fuse retainer cap. The cap has a spring-loaded locking feature which needs to be disengaged by pushing the cap inwards whilst turning it anticlockwise. The fuse carrier and fuse can then be withdrawn from its socket.

2Renew the protection fuse with a fuse of the same type and rating.

3Refit the protection fuse in reverse order.
