2.28 HANDING OVER

After completing the installation and commissioning of the system the installer should hand over to the householder by
the following actions:
1. Hand the User Instructions to the householder and
explain his/her responsibilities under the relevant national
regulations.
2. Explain and demonstrate the lighting and shutting down
procedures.
3. The operation of the boiler and the use and adjustment of all
system controls should be fully explained to the householder,
to ensure the greatest possible fuel economy consistent with
the household requirements of both heating and hot water
consumption.
Advise the User of the precautions necessary to prevent
damage to the system and to the building, in the event of the
system remaining inoperative during frosty conditions.
4. Explain the function and the use of the boiler heating and
domestic hot water controls.
Explain that due to system variations and seasonal
temperature fluctuations DHW flow rates/temperature
rise will vary, requiring adjustment at the draw off tap. It
is therefore necessary to draw the user's attention to the
section in the Users Instructions titled "Control of Water
Temperature" and the following statement:
"Additionally, the temperature can be controlled by the
user via the draw-off tap: the lower the rate the higher
the temperature, and vice versa".
5. Explain the function of the boiler fault mode.
Emphasise that if a fault is indicated refer to "Fault Codes" in
the User Guide.

Explain that the dial on the control panel front indicates
the central heating system pressure and that if the normal
COLD pressure of the system is seen to decrease over a
period of time then a water leak is indicated. Explain the re-
pressurising procedure and if unable to re-pressurise or if the
pressure continues to drop a registered local heating installer
should be consulted. Refer to Section 2.17.
