Chithunzi 1: Zaphulika view of the Lunos e² decentralized ventilation units and accompanying accessories. This image shows two complete ventilation units, two round ducts, a universal control unit, a power supply, and a wall switch. Each ventilation unit consists of an outer grille, a fan, a ceramic heat exchanger, and an inner panel with a filter.
The Lunos e² system includes:
- Two Lunos e² decentralized ventilation units with heat recovery.
- Ceramic storage elements, EPP foam housing, thermal insulation, G3 filter, and reversible EC motor.
- Two round ducts (DN160 mm, 5000 mm length).
- Two 1-WE 180 white exterior grilles (screw-on type).
- Two 9/IBE interior panels with filter.
- One 5/UNI-FT universal control unit for Lunos e².
- One 5/NT18 power supply (18W) for the universal control unit.
- One 5/W2U switch for the universal control unit.
Kukhazikitsa ndi Kuyika
Installation should be performed by a qualified professional. Ensure all local building codes and regulations are followed.
Macheke oyikatu:
- Verify wall thickness: Minimum 300 mm.
- Ensure required hole diameter: 162 mm.
- Confirm power supply (12V DC) is available at the installation site.
Masitepe oyika:
- Drill a 162 mm diameter hole through the wall at the desired location, ensuring a slight downward slope to the outside for drainage.
- Insert the round duct (DN160 mm) into the drilled hole. Cut the duct to the appropriate length for the wall thickness.
- Install the Lunos e² ventilation unit into the duct. Ensure the ceramic heat exchanger and fan are correctly oriented.
- Mount the exterior grille (1-WE 180) on the outside of the wall, securing it with screws.
- Mount the interior panel with filter (9/IBE) on the inside of the wall.
- Connect the ventilation units to the 5/UNI-FT universal control unit.
- Connect the 5/NT18 power supply to the universal control unit and to the main power.
- Install the 5/W2U switch in a convenient location and connect it to the universal control unit.
Malangizo Ogwiritsira Ntchito
The Lunos e² system is designed for continuous operation to maintain optimal indoor air quality and heat recovery.
Ntchito Yoyambira:
- Use the 5/W2U switch to turn the system ON/OFF.
- The universal control unit (5/UNI-FT) allows selection of different operating modes and fan speeds. Refer to the control unit's specific manual for detailed programming.
- The system operates by alternating airflow direction every 70 seconds, allowing the ceramic heat exchanger to absorb heat from outgoing air and release it to incoming fresh air.
Njira Zogwirira Ntchito:
The Lunos e² system typically offers multiple fan speed settings to adjust ventilation rates:
- Kuthamanga Kwambiri: 18 m³/h (1.4 W power consumption) - Ideal for continuous background ventilation.
- Liwiro Lapakatikati: 31 m³/h (2.8 W power consumption) - For increased ventilation needs.
- Liwilo lalikulu: 38 m³/h (3.3 W power consumption) - For rapid air exchange, e.g., after cooking or showering.
The system also features humidity recovery, typically around 20-30%, to prevent excessive drying of indoor air during colder months.
Kusamalira
Regular maintenance ensures optimal performance and longevity of your Lunos e² ventilation system.
Kusintha/Kuyeretsa Sefa:
The G3 filter should be checked regularly and replaced or cleaned as needed, typically every 3-6 months depending on air quality.
- Turn off the ventilation system at the main switch.
- Carefully remove the interior panel.
- Remove the G3 filter.
- Clean the filter by vacuuming or gently washing with warm water (if washable type). Allow to dry completely before reinstallation. Replace if heavily soiled or damaged.
- Reinsert the clean/new filter and reattach the interior panel.
- Turn the system back on.
Ceramic Heat Exchanger Cleaning:
The ceramic heat exchanger should be cleaned annually or if performance degrades.
- Turn off the ventilation system.
- Remove the interior panel and filter.
- Carefully pull out the ceramic heat exchanger unit.
- Clean the ceramic core under running water. Do not use harsh detergents. Allow to dry completely.
- Reinsert the dry ceramic heat exchanger, ensuring correct orientation.
- Reinstall the filter and interior panel.
- Turn the system back on.
Exterior Grille Cleaning:
Periodically inspect and clean the exterior grille to ensure unobstructed airflow.

If you experience issues with your Lunos e² system, consult the following table before contacting support.
| Vuto | Chifukwa Chotheka | Yankho |
|---|---|---|
| System not operating | No power supply; switch is OFF. | Check power connection; ensure switch is ON. Verify power supply (5/NT18) is functioning. |
| Reduced airflow or efficiency | Clogged filter; dirty ceramic heat exchanger; obstructed exterior grille. | Clean or replace filter; clean ceramic heat exchanger; clear any obstructions from the exterior grille. |
| Phokoso losazolowereka | Fan obstruction; loose components. | Turn off system and inspect fan for obstructions. Ensure all components are securely installed. If noise persists, contact support. |
| Condensation around unit | Improper installation (e.g., no downward slope); extreme temperature difference. | Ensure proper installation with slight downward slope. If problem persists, consult a professional. |
