Introduction

These mounting instructions show the removal of the existing pressure switches and the installation of a new adjustable pressure switch using the example of an LHL5E condensing unit with a 4 cylinder ECOLINE compressor.

These instructions are also applicable for the conversion of LHL3 condensing units. Since this series contains 2 cylinder compressors, the different positions of the suction and discharge gas valves, and the connections for the high and low pressure switches at the compressor must be considered!

Connections 2 cylinder compressors (LHL3E)

Connections 4 cylinder compressors (LHL5E)
