6.2.9 ELECTRICAL WIRING
A standard 3 pin plug and cord are
provided.Itis essentialthatthe correct
polarity is maintained as should they
be reversed the boiler will continually
lockout.Shouldtheleadbe damaged,it
mustbe replacedbya speciallead from
HUNTHEATING.Thepowersupplymust
be single-phase 230V - 50 Hz through
a main switch protected by a 3 A fuse
withadistanceofatleast3mmbetween
contacts.
NOTE:
The boiler must be connected with an
efficient grounding system. HUNT shall
not be held liable for injury or damage
resulting from failure to ground the
boiler.
ATTENTION:
The boiler controls only put the unit in
standby. Before working on the applian-
ce isolate it from the power supply.
