When installing the Carrier 30XBZE 30 Air Cooled Chiller, it is important to consider safety measures and comply with regulations. Here are some guidelines to help you with the installation:
1. Risk Analysis: Before installation, conduct a risk analysis to assess potential risks and determine necessary safety measures. The responsibility for safety measures lies with the customer.
2. Flammability Risk: The chiller uses refrigerants belonging to the A2L category, which are mildly flammable. Take precautions to prevent fluid from entering buildings, such as maintaining distance from openings and using hydraulic circuits and external relief valves.
3. Potentially Flammable Zone: The manufacturer has defined a potentially flammable zone where ignition sources should not be present. Ensure that no ignition sources are introduced in this zone. Additional equipment, if required, should be installed outside the potentially flammable zone and qualified as non-ignition sources.
4. Installation Cases: Consider the specific installation case to determine the appropriate safety measures. The installation cases mentioned in the manual include free field installation, outdoor confined space installation, installation over a pit, acoustic package installation, under shelter or covered area installation, and indoor installation.
5. Leak Detection: Install leak detectors at the lowest point of identified accumulation areas to detect any refrigerant leaks. The unit has an option for an input contact for refrigerant leak detection, which can be used through a building management system or other safety measures.
Please note that this answer provides general guidance and should not replace the risk analysis and compliance with regulations. Always refer to the manufacturer's manual and instructions for detailed installation guidelines specific to your unit.
