6.1 For replacing filters
The replacement period of the filter depends on
local circumstances. We recommend replacing the
filter when replacing the ComfoAir Luxe filter.
Replace the filter (at least) once every six
months.
1. Disconnect the ComfoAir Luxe from its power
supply.
2. Remove the filter handle (A) from the
Comfofond-L.

4. Slide the new filter back into the Comfofond-L.
5. Click the filter handle (A) in the Comfofond-L.
6. Return power to the ComfoAir Luxe.
Filters must be replaced with the original
manufacturer’s filters only.
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:
Only a recognized cooling-technology fitter
may top up the Comfofond-L.
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 fluid 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. Pre-pressurise the system to 1.5 bar using the
water pressure from the mains. Use the filling
hose on filling valve V3 for this.
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 condensation drain 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:
