NOTICE: Debris from the system can damage the boiler
and reduce efficiency. Failure to comply with the
guidelines for the use of water treatment with the
appliance will invalidate the appliance warranty.
NOTICE: SOFTENED WATER
▶ ARTIFICIALLY SOFTENED WATER MUST NOT BE
USED TO FILL THE CENTRAL HEATING SYSTEM.
ENSURE THAT THE SYSTEM HAS BEEN CLEANED AS ON PAGE 11 OF
THESE INSTRUCTIONS.
INHIBITOR (Central Heating):
▶ Check drain cocks are closed and all radiator valves are open before
adding a suitable inhibitor compatible with aluminium (or combined
inhibitor/anti-freeze if the system is exposed to freezing conditions)
to the heating system water in accordance with the manufacturers
instructions.
The pH value of the system water must be less than 8 or
the appliance warranty will be invalidated.
▶ Fill the system to between 1 and 1.5 bar via the supplied internal
WRAS approved filling loop figure 32 on page 26.
▶ Vent the boiler and all radiators; retighten vents when complete.
▶ Record the date when the inhibitor was added to the system on the
guarantee card.
NOTICE:
▶ The concentration of inhibitor in the system should
be checked every 12 months or sooner if system
content is lost.
▶ The addition of sealing agents to the system water is
not recommended as this can cause problems with
deposits left in the heat exchanger.
▶ In cases where all attempts to find a micro leak have
failed, Worcester, Bosch Group supports the use of
Fernox F4 leak sealer.
