Notes:
-
The installation must be protected against frost.
-
The unit’s hydraulic module and the water type heat exchanger may be protected
(factory-fitted option) against freezing using electric heaters and heat trace
cables (13)
- The pressure sensors are assembled on connections without Schrader.
Depressurise and drain the system before any work.
