- A minimum running time of 3 min. steady-state condition (continuous operation) must be achieved. Avoid continuous operation in limit range. LP = Low pressure Max. permissible operating : 100/150 bar HP = High pressure pressure (LP/HP) 8 | AQ450745530628en-000301 © Danfoss | Climate Solutions | 2023.09... -
Page 9: Compressor Assembly
Do not use in a corrosive, dusty, damp atmosphere or a com- bustible environment. Setup on an even surface or frame with sufficient load-bearing capacity. Single compressor preferably on vibration damper. Compound connection basically rigid. AQ450745530628en-000301 | 9 © Danfoss | Climate Solutions | 2023.09... -
