INSTALLATION

ELECTRICAL CONNECTIONS

Power supply

The boiler operates with a 230 V - 50 Hz single phase supply. A double pole isolator with a 6 amp fuse or a 6 amp MCB must be fitted outside the boiler to allow power to be shut off during servicing and before any repairs are carried out on the boiler.

Conformity

Boiler installation must comply with the prevailing local standards and legislation.

Safety

The stainless steel tank must be earthed separately.

The power to the boiler must be switched off before any work is carried out.
