Failure to connect the overflow-outlet to a permanent waste or drain, could lead to property damage 
from flooding.  

 

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. 

 

 

The boiler is now ready for use.      

 
 

REGULAR DAILY USE 

 

Switch boiler on and wait for the screen to turn white and show “READY” message. The water will then 

be at the correct temperature. 

 

Dispense water via the lever tap. (CAUTION: Boiler dispenses near-boiling water).  

 
 

SETTING & ADJUSTING FILTER MONITOR (Optional): 

 

The unit as a built-in optional filter monitor. This monitor can be used with any external water filter or 
softener. To turn this option on as below: 
 

-

 

Turn machine off.  

-

 

Press & hold “on/off” button (for approximately 12 seconds) until red screen shows “PR” in top

-

right corner, then release button. Temperature setting is displayed.    

-

 

Press  &  hold  button  (long  push)  for  approximately  5  seconds  until  screen  changes  to  show 

Empty Filter Symbol

” (default filter setting

 - OFF). 

-

 

Press button (short push) to scroll between the different filter settings; 

SOFT 
MEDIUM 
HARD 
EMPTY FILTER SYMBOL (No Filter monitor) 

Hard  and  Soft  Water:  The effectiveness  of the  filter will  be 

reduced in hard water areas

  (and  should  be 

replaced more frequently), or 

extended in soft water areas

 where scale is less of a problem.    

-

 

With the required filter setting selected, Press & hold button (long push) for 4 seconds to save. 

-

 

Press & hold button (long push) for approximately 6 seconds until display goes blank. 

-

 

Turn machine back on again.
