4 Maintenance
4.1 Tasks at the start and end of the heating season
At the start of the cooling season
● Install new batteries in the remote control.
● Check that the cooling unit is installed correctly.
● Check that the cooling unit’s air flow is free of obstructions.
● Check that there are no bends, dents, or blockages in the condensate drain pipe.
● Do not start the cooling unit without air filters. Unfiltered air may cause issues in the
unit’s operation.
At the end of the cooling season
● Turn off power from the main switch.
● Clean the cooling unit and the air filters.
● To remove moisture from inside the unit, run the fan with the FAN function for 2–3
hours.
● Remove the batteries from the remote control.
Outside the cooling season, it is recommended to run the equipment for a short time
every 2 months. This will lengthen the life of the circulation pump.
4.2 Cleaning the air filter
Do not wash the filters with hot water (temperature higher than 40
degrees). Dry the filter thoroughly before reinstallation. Do not dry in
direct sunlight or near another heat source.
Clean the air filter regularly. If the air filter is dirty, air flow will be weaker, which will
increase power consumption. In extremely dusty environments, clean the air filter once
every two weeks or as often as necessary. The blue air filter prevents bacteria and
mold from growing in the dirt captured by the air filter.
1. Open the front grille and remove the air filter.
2. Vacuum the air filter.
3. If necessary, wash the filter with mild detergent. Dry carefully before reinstalling.
4. Reinstall the filter. Check that the air filter is properly in its place.
5. Close the front panel with care.
14 (20) M8014 2337EN

If the air filter is not installed properly, the cooling unit may not start.
4.3 Cleaning the cooling unit
Preparations
1. Shut down the cooling unit with the remote control.
2. Disconnect power from the unit’s main switch or detach the unit’s power cable.
3. Make sure that the fan has stopped completely.
4. Direct the horizontal air deflectors downwards.
Removing the horizontal deflectors
1. Release the latches (pos. 1 and 2) for the upper deflector by sliding them from left
to right.
2. Slide the deflector first towards the left and then remove it by pulling it towards you
(pos. 3).
Remove the lower deflector in the same way (pos. 4, 5, and 6).
Opening the vertical deflectors
The vertical deflectors cannot be removed, as they are attached with hinges to the
ends of the cooling unit.
Open the vertical deflectors like a double door, one at a time.
1. Hold the deflector on the left in place. Pull the deflector on the right out through the
middle, turning it towards the right.
2. Pull the left deflector out through the middle, turning it towards the left.
M8014 2337EN 15 (20)

Cleaning
Carefully clean the air outlet and fan. If the air outlet or fan are dirty, clean with a moist
towel. If necessary, use mild detergent. Dry with a dry cloth.
Do not use solvents or polishing compounds for cleaning.
Reattaching the deflectors
1. Close the vertical deflectors one by one, starting from the left.
● To avoid damage to the deflectors, make sure that they are in correct position.
2. Reinstall the horizontal deflectors, starting from the lower deflector.
● The upper and the lower deflector have different latches.
3. Switch on power from the main switch (or plug in the cable).
● When starting the cooling unit after cleaning, some debris released during
cleaning can come out of the air outlet.
If the cooling unit screen does not power on during restart, the air deflectors are not
properly in place. Turn off power from the main switch (or disconnect the power cable)
and repeat the steps above.
4.4 Troubleshooting
Problem Cause/corrective action
The cooling unit does not start. Check the wires for damage.
Check if a fuse has blown or circuit breaker tripped.
The unit works but doesn’t provide
enough cooling.
Check the room temperature setting.
Check if the air filter is dirty or clogged.
Check if apartment doors or windows are closed.
Check if air flow from the cooling unit is blocked.
Check if the unit’s brine circulation is blocked.
Check the brine circulation for air bubbles.
Check that the brine circuit pump is operating correctly.
There is steam coming out of the
unit when the unit is in operation.
Water vapor may form when hot indoor air and cold cooling air
become mixed.
The remote control does not work. Check the remote control’s batteries.
