2 Safety instructions
These instructions are exclusively designed for qualified competent
persons.
▪ Work on gas units must only be carried out by a qualified gas
fitter.
▪ Work on electrical equipment must only be carried out by a
qualified electrician.
▪ The system must be commissioned by a qualified competent
person.
WARNING
A qualified person shall explain the operating principles
and the use of the unit to the user. The user is not allowed
to perform any modifications, maintenance or repairs on
the unit, unless otherwise stated, or have the such
performed by unauthorised third parties. Otherwise, the
unit warranty becomes void.
DANGER
Isolate the boiler from the power mains before working on
it.
WARNING
Unit installation, commissioning, repair, configuration and
service must be performed by qualified competent persons
in accordance with local standards and regulations.
Incorrect installation of this unit may harm the user and his/
her surroundings. The manufacturer is not responsible for
any malfunctions and/or damage that may occur this way.
DANGER
Flammable fluids and materials must be stored at least
1metre away from the boiler.
WARNING
To ensure faultless operation, long term availability of all
functions and long working life of the boiler only use
original spares.
3 About the unit
This Daikin unit is a wall-mounted gas-fired condensing boiler that
can supply heat to central heating systems, as well as supply
domestic hot water. Depending on settings, it is possible to use the
unit solely for hot water or solely for central heating. Hot water
supply type can be instantaneous or by means of a hot water
storage tank. The type of the boiler can be recognised from the
model name written on the identification label. See table below:

A control unit, which contains a user interface, controls the ignition,
safety systems, and other actuators. User interaction is provided via
that user interface, which is composed of an LCD screen, push
buttons, and two dials, and which is located on the front cover of the
unit.
3.1 Safety systems
The unit is equipped with several safety systems, to protect it against
dangerous conditions:
Flue safety system: This is controlled by the flue gas temperature
sensor located on the flue outlet part of the boiler. It is activated
when the flue gas temperature exceeds safety limits.
Overheating safety system: This is controlled by the safety limiting
thermostat. It is located on the main heat exchanger and stops the
unit when the flow temperature reaches 100°C, to avoid boiling of
the water, which may damage the unit.

- Residual pump lift graph 12
- The residual pump lift graph shows the amount of pump lift mbar that remains for the central heating circuit 12
- Underfloor heating requirements 12
- Underfloor heating systems apparently require higher flow rate and lower δt this boiler can be connected to an underfloor heating system without use of a second pump and low loss header because of its high pump capacity direct connection is possible when the system is well designed and pressure loss is low enough 12
- Warning 12
- When the boiler is connected to underfloor heating installation the maximum central heating set temperature must be limited to 50 c and the pump operation temperature difference must be adjusted to 10 kelvin in the service settings menu to change this setting refer to the servicing instructions 12
