6 Maintenance
Failure to carry out (periodic) maintenance
on the ComfoFond-L ultimately compromises
the performance of the system.
The ComfoFond-L should be inspected and
cleaned annually by a specialist. To ensure a
hassle-free lifespan for your ComfoFond-L, we
recommend you take out a service agreement
with an expert company.
The following maintenance may be carried out
by the user:
Replacing the filter;
Checking the system pressure..
A concise explanation of these maintenance
activities is given in the paragraphs below.
Ensure the ComfoFond-L has been disconnect
from mains power before carrying out any
maintenance work. To do this disconnect the
power to the ComfoAir Luxe to which it is
connected.
Bear in mind that the fluid circuit is
pressurised.
The power to the ComfoAir Luxe should not be
disconnected unless the ComfoFond-L or
ComfoAir Luxe are to be taken out of service
due to a serious malfunction, or for filter
replacement or any other compelling reasons.
If the power to the ComfoAir Luxe is discon-
nected, mechanical ventilation of the dwell-
ing will cease. This can lead to a build-up
of moisture and results in problems with
mould. Long-term deactivation of the
ComfoAir Luxe must therefore be prevented.
For maintenance of the ComfoAir Luxe, please
read the instructions in the ComfoAir Luxe man-
ual. A copy of this manual can be obtained from
Zehnder.
