Key
Components of the hydraulic module and the unit
1 Screen lter (particle size of 1.2 mm)
2 Expansion tank (option)
3 Relief valve
4 Circulating pump (single or dual)
5 Air vent
6 Water drain tap
7 Pressure sensor
Note: Provides pressure information for the pump inlet (see Control manual)
8 Temperature sensor
Note: Provides temperature information for the water exchanger outlet
(see Control manual)
9 Temperature sensor
Note: Provides temperature information for the water type heat exchanger inlet
(see Control manual)
10 Pressure sensor
Note: Provides pressure information for the water exchanger outlet (see Control
manual)
11 Check valve (If dual-pump)
12 Plate heat exchanger
13 Heater or heat trace cable for frost protection (Option)
14 Water type heat exchanger ow rate sensor
15 Water bu󰀨er tank module (Option)
Installation components
16 Pocket
17 Air vent
18 Flexible connection
19 Shut-o󰀨 valve
20 800 µm screen lter (mandatory for a unit without a hydraulic module)
21 Pressure gauge
22 Water ow control valve
Note: not required if hydraulic module with variable-speed pump
23 Charging valve
24 Bypass valve for frost protection (if shut-o󰀨 valves are closed (item 19) during
winter)
25 Bu󰀨er tank (if required)
---- Hydraulic module (unit with hydraulic module option)
Notes:
- The installation must be protected against freezing.
- The unit's hydraulic module and the water type heat exchanger may be protected
(factory-tted 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.
