  • Page 3 IMPORTANT NOTICE AND SAFETY SUMMARY 1. Introduction This Engineering Manual concentrates on the Low Ambient VRF Heat Pump Outdoor Unit. Read this manual carefully before performing installations or operations. This manual should be considered as a permanent part of the air conditioning equipment and should remain with the air conditioning equipment.
  • Page 4 Take the following precautions to reduce the risk of property damage. Be careful that moisture, dust, or variant refrigerant compounds not enter the refrigerant cycle during installation work. Foreign matter could damage internal components or cause blockages. Do not install this unit in any place where silicon gases can coalesce. If the silicon gas molecules could run inside of the electrical box, possibly causing electrical failures.
  • Page 5 Installation Precautions To reduce the risk of serious injury or death, the following installation precautions must be followed. When installing the unit into… construct a strong wood or metal frame to provide added support. A room: Properly insulate any refrigerant tubing run inside a room to prevent “sweating” that can Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the unit to prevent water damage and abnormal vibration.
  • Page 6 Refrigerant Precautions To reduce the risk of serious injury or death, the following refrigerant precautions must be followed. have been approved for use in the countries or markets they serve. The refrigerant used in this unit the warranty and will increase the potential risk of injury or death. If installed in a small room, take measures to prevent the refrigerant from exceeding the maximum allowable concentration in the event that refrigerant gases should escape.
  • Page 7 Electrical Precautions explosion resulting in serious injury or death. Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause serious injury or death. Perform all electrical work in strict accordance with this installation and maintenance manual and all the relevant regulatory standards.
