---- Hydraulic module (unit with hydraulic module option)
Notes:
- The installation must be protected against frost.
- The unit's hydraulic module and the water type heat exchanger may be
protected (factory-tted option) against frost 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.
