Does the MonoControl CS gas pressure regulation system have to be maintained?

No, Truma MonoControl CS requires no maintenance.

However, in Germany, the gas system must be inspected every two years by an LPG expert (DVFG, TÜV, DEKRA). The inspection must be confirmed on the corresponding inspection certificate. For your own safety, we recommend that you have the gas system inspected every two years also in countries where this is not mandatory.
