At the time of commissioning, complete all relevant
sections of the Benchmark Checklist located on the
inside back pages of this document.
• Checkthatthedifferentialbreakerisinstalled.

14.1 filling the glycol circuit
b
Warning! Do not dispose of glycol into drains and the
environment.
b
We recommend that you use propylene glycol
enriched with corrosive inhibitors.

The level of glycol may decrease during the first month
following the commissioning of the installation. It may
also vary in accordance with the outdoor temperature.
