ERASE ALL:
This function clears all keys from the
memory. It will ask for confirmation by pressing “eco”
button. Should you not wish to clear the keys, simply
press the “On/Off” button as normal to exit the menu.
Each DB2000 boiler can sync with 24 different keys,
all with a unique combination. A key can be learnt by
more than one machine to allow its use in multiple
areas of the same building.
NOTE:
Additional “keys” are available from
Instanta spares dept. (Tel: 01704 501114),
Part No: DBKF021
Cleaning
The external surfaces of the machine can be kept
clean by wiping with a damp cloth. A good quality
stainless steel cleaner will keep the machine in its
original condition. The plastic top trim may also be
cleaned with a damp cloth. Do not use abrasive
material on the outer surface of the machine.
Maintenance & Service
Information
The boiler should be periodically checked for scale
build-up. The frequency depends upon hardness
of the water and whether or not an effective scale
reducer is fitted.
Apart from cleaning/de-scaling the level sensors and
tank, no regular maintenance should be required.
DE-SCALING:
In hard water areas, the boiler should be descaled
on a regular basis to maintain efficient operation,
minimise energy consumption and also retain the
water quality.
Full de-scale of Tank & Probes:
• Disconnect machine from power supply.
• Empty the machine and allow to cool.
• Remove outer-lid (spring-clips).
• Remove tank-lid (four/six fixing screws).
• Lift out the evaporation plates (inside of tank –
Remember order of removal).
• Remove as much scale as possible by hand.
Any scale which is difficult to remove can be
dissolved by using a de-scaling solution.
• Wipe clean the level sensing probes
(using non-metallic scourer).
• Flush with copious amounts of cold water to
ensure all traces of de-scaler are removed before
using the boiler again.
• Replace evaporation plates, tank-lid and
outer lid.
Clean & de-scale the Probes:
• Disconnect machine from power supply.
• Remove outer-lid (spring-clips).
• Remove tank-lid (four/six fixing screws).
• Lift out the evaporation plates (inside of tank –
Remember order of removal).
• Wipe clean the level sensing probes using a
non-metallic scourer. It is important to clean
the white insulators as well.
• Replace evaporation plates, tank-lid and
outer lid.
Service Warnings & Fault
Diagnostics
The DB2000 is fitted with an intelligent fault
diagnosing system. There are two levels of diagnosis.
1
Simple warnings
- accompanied by the
illumination of a red exclamation mark.
Your boiler will continue to operate as normal
whilst displaying these warnings.
2
Critical faults
- accompanied by the illumination
of a red spanner.
