CONDENSATE PUMP

• Luna devices with cooling function are equipped with a condensate drain pump as standard. The condensate is drained through a hose, which is routed to the upper part of the device, near the hydraulic connections. The hose should be connected to the collective condensate drain system.
• The maximum lifting height of the pump is 20 m.

FILTER INSTALLATION

• The LUNA device is equipped with a COARSE 70% (G4) air filter as standard, which is installed on the upper surface of the device. The filter should be replaced periodically, depending on the level of contamination or the number of hours of device operation. The T-box ZONE controller will indicate the need for air filter replacement after a certain number of operating hours. It is always recommended to use original filters.
• Please make sure that the filter is installed in the correct airflow direction (indicated on the filter frame).

• The first step is to remove the bottom cover of the device. To do this, you need to turn the Allen screw three times using a 2.5 mm hex key [A], and then rotate the screws at points [B] three times by hand. Next, rotate the entire cover in a counterclockwise direction.

• After removing the cover, it is necessary to disconnect the power supply and detach the carabiner supporting the bottom cover [C].

• Before proceeding with further tasks, it is important to empty the condensate tray by removing the drain plug and draining the condensate [15.3]. The drain plug is marked with an exclamation mark in figure [15.4].

• To remove the condensate tray, you need to completely unscrew the allen screw [A], remove the screws at points [B], and unscrew the 6 butterfly screws [E]. Then, carefully lower the tray.

• Empty the disassembled condensate tray of any condensate and clean it thoroughly. Rinse the filter marked at point [F] with water and clean it.

• Disconnect the condensate pump from the power supply and detach the condensate discharge tube from the pump [G]. Slide the pump to the left as shown in the diagram [G] and rinse it under running water [H].
