Maintenance

The WHI freshaqua modules are low in maintenance. However, as part of the

annual inspection of the domestic water system, the following items should be

checked/observed:

•

Check all connections for leaks

•

Check the safety equipment

•

Perform a functional check and check the setting parameters

•

Plausibility check of the control parameters and nominal values

•

Check the heat exchanger for dirt and functioning

We recommend concluding a maintenance agreement.
