4. Opsætning og installation
The TOSOT Cosmo Series Mini Split system requires professional installation. While designed for easier installation compared to central AC systems, specific HVAC and electrical knowledge is necessary. The system includes a 16.4-foot copper line set for each indoor unit, but the power cord is not included and must be sourced separately.
4.1 Key Installation Steps
- Mounting Indoor Units: Securely mount each of the four indoor units in their designated zones, ensuring proper clearance for airflow and maintenance.
- Placering af udendørsenhed: Position the single outdoor unit on a stable, level surface, allowing adequate space for air circulation and service access.
- Refrigerant Line Set Connection: Connect the provided copper line sets between each indoor unit and the outdoor unit. This step requires precise flaring, torqueing, and the use of Nylog sealant to prevent leaks.
- Elektriske ledninger: Connect the electrical wiring according to the wiring diagram provided in the detailed user manual. Ensure the correct voltage (230V) and breaker size (e.g., 40A) are used.
- Støvsugning af systemet: Evacuate the refrigerant lines to remove air and moisture. This is a critical step for system efficiency and longevity. A vacuum pump must be used to pull a deep vacuum for at least 30 minutes per line set, and the vacuum must hold for at least an hour to confirm no leaks.
- Refrigerant Release: Once the vacuum test is successful, carefully release the R32 refrigerant from the outdoor unit into the system.
- Afløbsforbindelse: Ensure all indoor units have proper condensate drainage connected to prevent water leaks.


4.2 Kølemiddelinformation
This system utilizes R32 refrigerant, which has a 67% lower Global Warming Potential (GWP) and requires a 30% lower refrigerant charge compared to R410A systems, contributing to environmental benefits.
