• fit appropriately-sized expansion vessels to avoid water hammer from
damaging the system;
• install mechanical and/or magnetic filters to minimise the presence of
impurities in the circuit.
Caution: The water connections must always be completed by
qualified personnel who have the qualifications and authorisations
required by local regulations, using appropriate personal protective
equipment (PPE), who are aware of the necessary precautions and who are
able to correctly and safely complete all required operations.
Caution: The PS and TS values for the water circuit connected to the
HEOS BOX refer to the lowest PS or TS of all the components in the circuit.
The unit’s water connections have 1” GAS male threads on the CE versions;
the unit should be connected to the water loop without any reductions
in diameter, as such reductions may affect the unit’s performance or
(*): the water and refrigerant connections are located on the opposite
side to the electrical connections, as shown in the figure: the refrigerant
connections are made using pipe couplings whose diameter and thickness
varies according to the size of the unit, see “Refrigerant connections”.

4.2 Water connections
Refer to Figure 4.a.
Caution:
before continuing, make sure the unit is powered off,
placing disconnect switch QS1 and the switch or disconnect device on the
HEOS BOX power supply line in the OFF position (see the wiring diagram).
The mains power disconnect device must have a contact opening
distance that allows complete disconnection in overvoltage category III
conditions; it must also be incorporated into the HEOS BOX power supply
line in accordance with national regulations.
To simplify installation and maintenance:
• install a manual shut-off valve immediately before the water inlet to the
unit (the valve is not supplied by CAREL);
• install automatic air vent valves (not supplied by CAREL) in the piping, at
the highest positions in the circuit;
• avoid piping layouts in which water may stagnate when the system is
stopped;
