Specific installer safety instructions 3 Specific installer safety instructions Always observe the following safety instructions and regulations. Unit installation (see "6 Unit installation" [ 24]) WARNING Installation shall be done by an installer, the choice of materials and installation shall comply with the applicable legislation. In Europe, EN378 is the applicable standard. "6.1 Preparing the installation site" [ 24]) - Page 15 Specific installer safety instructions WARNING Connect the refrigerant piping securely before running the compressor. If the refrigerant piping is NOT connected and the stop valve is open when the compressor is run, air will be sucked in. This will cause abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
