8.2 Refrigeration circuit
General notes
8.2.1
Refrigeration equipment is subject to the EG Pressure Equipment Directive (2014-68-EG) and
-
requires special handling and special care.
Start up the refrigeration circuit only if it was properly installed, evacuated and filled - Never
-
start a compressor under vacuum.
It is essential that the glide of refrigerant blends as R407C is carefully considered when adjust-
-
ing superheat controls.
Air inlet and thus the entry of humidity into the refrigeration circuit must be avoided rigorously,
-
since the refrigerant oil is highly hygroscopic. The water, which is absorbed by the oil cannot be
removed sufficiently.
8.2.2 Manually starting the compressor via TRANE control system
The compressor can be started via the display of the TRANE control system as:
1. Start page All Settings Password handling Enter the password
Note: Manually starting the compressor can only be performed at service level (Password level
4; key symbol: 2 keys). The 4-digit password for the service level is 6975.
2. Start page All Settings Inputs/Outputs Digital outputs Compressor 1 ( / Compressor
