The 4 Way Valve (6):
The 4 way valve changes the direction of flow for the defrost cycle.
Liquid Receiver (7):
To compensate the different refrigerant charge required in heating and pressure connections
SAE 5/16” – UNF ½” – 20 equipped with pin, gasket and blind nut, as required for the use of R410A refrigerant (they
allow the complete check of the refrigerant circuit: compressor inlet pressure, compressor outlet pressure and
expansion valve upstream pressure). All the pipes on the refrigerant circuit are insulated to avoid condensation
formation and minimise thermal losses.
The Axial Fans (8):
Are equipped with a high efficiency electronically commutated (EC) motor and guarantee high
efficiencies in all the operating conditions.
Hydraulic Circuit:
All the pipes are thermally insulated to avoid condensate formation and minimise thermal losses.
This circuit is equipped with a modulation circulation pump internal to the casing designed to flow water to the nearest
thermal / buffer store - a high head circulation pump is an additional option and will need to be ordered at the same
time as the S-ASX heat pump is order.
Electrical Wiring Panel:
It contains all the power, control and security components necessary to guarantee the unit to
work properly. The unit is managed by a separate controller to which all the electrical loads and the control devices
are connected. The user interface, to be placed indoor, allows to view and to modify, if necessary, all the parameters
of the unit.
