Periodic checks
î
Check regularly that the wa-
ter pressure of the system is
at least 1.2 bar when cold. If
not, top up the system with
water as instructed by the
installer at appliance instal-
lation or call your installer.
î
If a topping up of the system is required
to maintain the minimum recommend-
ed water pressure, always turn the ap-
pliance off and only add small quanti-
ties of water at a time. If a large amount
of cold water is added in a hot appli-
ance, the appliance can be damaged
permanently.
î
If the system needs to be topped up
regularly, there may be a leak in the
system. In that case, call your installer.
î
Check regularly that there is no water
below the appliance. If there is, call
your installer
î
Check regularly that there is no error
code displayed on the control panel
screen. Call your installer as required.
When cleaning the appliance
cabinet panels, do not use sol-
vents or aggressive/abrasive
cleaning agents. Wipe the sur-
faces using a soft clean cloth,
water and soap.
i
î
If works need to be per-
formed close to the appli-
ance (e.g. in the boiler room
or close to the air inlets),
make sure that the appli-
ance is shut down to pre-
vent the ingress and accu-
mulation of dust.
î
In case of abnormal noises in the sys-
tem or the appliance, please notify a
qualifi ed professional.
î
Any setting of the appliance by the
end-user using the installer-specifi c
functions, that would cause the ap-
pliance to malfunction, could result in
damages to the equipment. Only the
end-user settings described in this
manual are available to the end-user.
î
If a condensate neutralisation sys-
tem is installed, have it checked and
cleaned at least once a year.
