6.2 Cleaning condensation drain
Inspect the ComfoFond-L condensation
drain at least once a year.
1. Disconnect the ComfoAir Luxe from its
power supply.
2. Disconnect the condensation drain.
3. Perform the following checks of the
condensation drain siphon:
Check whether the drain is still open by
adding extra water to the siphon;
Visually inspect the condensation drain
for contamination;
Check that there is enough water in the
siphon. Air may not pass through the
siphon;
4. Resolve any established problems;
5. Reconnect the condensation drain;
6. Return power to the ComfoAir Luxe.
6.3 Inspecting brine loop
Inspect the brine loop at least once a year.
Check the system pressure on the pressure
meter. Top up the system if required.
The brine loop pressure must be between 0.5
and 2.5 bar for the system to operate well.
The ideal pressure is 1.5 bar.
Filling instructions:
Top up the system as follows:
1. Disconnect the ComfoAir Luxe from its
power supply.
2. Remove the filter handle from the
ComfoFond-L.
3. Release the front panel by removing the
6 screws.
4. Remove the front panel from the
ComfoFond-L.
5. Connect a filling hose to filling valve V3.
6. Open filling valve V3.
7. Measure the glycol percentage using a
glycol meter.
- Fill the system with a ready-made brine
mixture first if required. The filling
instructions for this are given in the
‘Filling the brine loop’ section.
The glycol percentage deviation from the
selected percentage during installation
may not exceed -3%. The desired glycol
percentage must be restored first after
topping up the system twice with water.
8. Increase the pressure in the device to
1.5 bar. To that end, use the filling hose
connected to filling valve V3. Use an
additional pressure pump if necessary.
9. Closing filling valve V3 and disconnect the
filling hose.
10. If no further maintenance is required:
Install all parts in reverse order. (from point
4 back to point 1)
6.4 Cleaning internal siphon
Inspect the ComfoFond-L internal siphon at
least once a year.
1. Remove the front panel of the
ComfoFond-L as described in the brine
loop maintenance section.
2. Perform the following checks of the
ComfoFond-L internal siphon:
Check whether the drain is still open by
adding extra water to the siphon;
Visually inspect the siphon for
contamination;
Check that there is enough water in the
siphon. Air may not pass through the
siphon.
3. Resolve any established problems.
4. If no further maintenance is required:
Install all parts in reverse order (as
described in the maintenance section for
the brine loop) and switch the power supply
to the ComfoAir Luxe back on.
6.5 Maintenance of ComfoFond-L
casing
Inspect the ComfoFond-L casing at least
once a year.
1. Remove the front panel of the
ComfoFond-L as described in the brine
loop maintenance section.
2. Perform the following checks:
Check the seals for damage;
Check the inside and outside for dirt and
damage;
Check the duct connections for dirt and
damage.
Any signs of corrosion and other damage
must be treated directly and appropriately.
To clean the whole ventilation system, we
recommend hiring a specialized cleaning firm.
