6.5 Hydraulic connections
When preparing to connect the hydraulic circuit for the evaporator (refer to the diagrams included in the manual), it is good
practice to comply with the following instructions and in any case to follow national or local regulations.
Fit the pipes to the unit using flexible couplings in order to prevent transmission of vibrations and compensate thermal
expansion. (Proceed on the pumps unit in the same way).
Install the following components on the pipes:
- Temperature and pressure indicators for normal maintenance and control of the unit.
- Wells on the inlet and outlet pipes for temperature measurements, if temperature indicators are not present.
-
Shut-off valves (ball gate valves) to isolate the unit from the hydraulic circuit.
- metal mesh filter with a mesh size no larger than 1 mm, situated on the exchanger inlet pipe, to protect the exchanger
from slag or impurities in the pipes.
- Air valves, to be placed in the highest parts of the hydraulic circuit, to allow the non-condensable gases to be bled off.
- Expansion vessel and automatic charging valve for maintaining system pressure and to compensate thermal expansion.
- Drain valves, so that the system can be emptied for maintenance operations or seasonal stops.
It is mandatory to comply with the above requirements to facilitate the hydraulic connection operations and
the maintenance operations.
If supplied with the unit, it is mandatory to install the flow switch at the chilled water outlet connection. If the
flow switch is not installed, the warranty is voided immediately.
It is mandatory to fit the metal mesh filter on the water inlet pipe. If the metal filter is not fitted, the warranty is
voided immediately.
If integration with another heat source is planned, make sure water circulation through the unit does not
exceed 65°C.
If it does, the high pressure switch and the safety valve of the unit will operate.
Fig. B.11 exemplifies the hydraulic connection of the unit to a system.
It is essential for the water to come in at the connection indicated in the dimensional diagram and with the
relevant label on the unit.
If it does not, there would be a risk of the evaporator being frozen since the antifreeze probe control would be thwarted.
The hydraulic circuit must be made in such a way as to ensure a constant flow of water to the exchanger in all operating
conditions.
If this is not done, there will be a risk of refrigerant returning to the liquid state at the compressor inlet, with the danger of it
breaking.
Operation with a variable water flow rate at the user-side exchanger is allowed only if the inverter pump is integrated in the
unit (and therefore supplied by the manufacturer) and if the hydraulic circuit is made in accordance with the manufacturer's
specific instructions.
The controller of units installed in systems for the production of domestic hot water is designed to control a diverter valve.
