First start - Start-up procedure

The following procedures should be completed in the sequence in which they are
described:
7.5.1

Checking the electrical connection

Check that all electrical work has been carried out in accordance with the stand-
ards (e.g. protective earth, insulation, shielding, covers).
7.5.2

Leak test

See nameplate for permissible operating pressure.
The necessary safety precautions must be taken before performing the leak test.
Prior to the pressure test, the valve positions must be checked.
For testing, perform a pressure loss test for approx. 3 hours with dry nitrogen.
For compressor packages, perform the pressure loss test with a test pressure of
7 bar, for chillers and heat pumps separate by low pressure side or high pressure
side 1 bar below maximum operating pressure.
A pressure drop of 2% is permissible during the 3 hours, while fluctuations of the
ambient temperature must be taken into account.
