IMPORTANT: Whichever overflow connection
is chosen, the diameter of the pipe used must
be no less than 15mm.
Failure to connect the overflow-outlet to
a permanent waste or drain, could lead to
property damage from flooding.
If in all circumstances, it is absolutely not
possible to direct the boiler overflow-outlet to a
permanent waste or drain, then the mains water
supply to the boiler should be isolated and the
unit switched off whenever it is left unattended
for long periods (e.g. overnight).
Whilst every reasonable precaution is taken
to prevent an overflow, Instanta cannot be
held responsible for any damage caused as a
result of incorrect installation or blockage of
the overflow or failure to direct the overflow
to a safe outlet.
Operation
First use (once water and electrical connections
have been made);
• Switch boiler on. The screen will light up red
and will run through an initial self-diagnostic
check before starting to fill with water
(screen reads; “NOT READY FILLING”).
• Once primed with water, the boiler will
begin to heat (screen reads; “NOT READY
HEATING”).
• When the correct temperature has been
reached, the display will change from Red to
White and will simply read “READY”.
• The boiler will then continue in a heat/fill
cycle until the tank is at full capacity.
(During the heat/fill cycle, small amounts of
water are added to ensure the water at the
tap is always at the correct temperature).
IMPORTANT NOTE:
In normal daily use, the
boiler may be used as soon as the “READY”
message is displayed, but on first install, wait at
least 15 minutes before starting to use.
• Drain off approximately 10 litres of water
(to flush the new filter cartridge through).
• The boiler is now ready for use.

so screen displays hour.

button (short pushes) until correct hour is
displayed.
