INSTALLATION
IMPORTANT
To ensure that the unit works to its full potential, you will require water pressure of at least 30psi (2
Bar). If this is not possible, a pump should be fitted.
Having ensured that the incoming water pressure is adequate, follow these simple instructions:
1. Provide a suitable stop-cock to isolate the machine for maintenance when needed
2. Connect the water between the stop-cock and the boiler using the food quality hose
provided. (do not use red or blue washing machine hoses as these will contaminate the
water)
ELECTRICAL SUPPLY
3. The 3kW model is fitted with a 13amp plug and should be plugged into a suitable socket. The
6kW model should be wired into a 30amp switched supply with an ELCB. (Only a suitable
electrician should undertake this work)
COMMISSIONING
4. Open the steam tap on the left hand side of the unit
5. Switch on using the switch on the front panel. The power light will illuminate and water will
start to enter the boiler. Once the bottom level sensor is reached. the unit will then start to
heat. When the water boils, steam will start to come from the steam nozzle. The steam tap
can then be closed.
6. The pressure in the boiler will start to rise and the needle in the gauge will respond. When
the needle reaches the pre-set pressure, the ready light will illuminate and the boiler will
start to fill and heat until it reached the high level sensor. The boiler is then ready to use.

7. If the red service light flashes four times, then pauses and repeats, the incoming water
pressure to the unit is too high. This can be adjusted using the internal pressure reduction
valve. Ring Instanta’s technical help line for advice – 01704 502911
8. If the red service light flashes five times, pauses and repeats, the incoming water pressure is
too low. This can be adjusted using the internal pressure reduction valve or an external
pump may have to be fitted. Ring Instanta’s technical help line for advice – 01704 502911
DAILY USE
Follow instruction 4 to 6 above. Venting the boiler using the steam tap should be done every time
the unit is switched on from cold.
CLEANING
Clean the external surfaces of the boiler regularly to maintain good hygiene
Empty the front drip-tray regularly
Wipe external surfaces of the boiler with a damp cloth. Do not use abrasive materials on the outer
surfaces.
Wipe the draw-off tap each day to keep clean and also prevent lime-scale deposits from building up
around the tap-outlet.
SERVICE WARNINGS AND FAULT DIAGNOSIS
Your boiler is fitted with an intelligent fault diagnosing system and is able to detect various fault
conditions. Some of these are less serious and the machine will continue to operate as normal, while
others are more serious and will disable the unit.
Before calling for service, switch the machine off at the mains supply. Open the steam tap to let the
pressure out of the boiler and switch back on after 10 minutes. If the fault does not clear, call technical
support for advice.
