DIAGRAM OF RECOMMENDED USE SIDE CONNECTION
Depending on the type of machine and the selected setup, some components may be integrated into the unit.
The accumulation tank is necessary in the event of the following:
•
the water in the system is very low
•
the unit will not be used in a private house (in an industrial process or other)

FREE COOLING - optional
To prevent the RISK OF FREEZING load the free-cooling coils and the corresponding hydraulic system with a glycolic water
solution.
The glycol percentage must be defined according to the min. temperature reachable in the installation place.
RECOVERY EXCHANGER - OPTIONAL
OPTIONAL - The unit can be equipped with exchangers
to allow the recovery:
TOTAL,
with 100% recovery of the condensation heat
the thermoregulation is performed by CLIVET control
system.
PARTIAL,
with 20% recovery, the management is
supplied by the customer ( pump, valves, thermostats,
etc: see the following diagrams)
The recovery input water must not be below 25°C, in
the event that, wrongful operations and breakages of the
unit can occur.
Water connections must be performed carefully as for the
evaporator (filter, circuit washing, etc) .
Perform all necessary interventions to avoid the RISK OF
FREEZING (tubes insulation, emptying of circuit, addition
of glycol, anti-freeze resistances) .
Water temperature can reach high temperatures (up to
100°C), therefore:
•
avoid the RISK OF BURNS by adopting the necessary
precautions (insulation of tubes, temperature detecting
station on water if the sanitary use is foreseen, etc)
Install safety valves and specifically dimensioned
expansion tanks in the hydraulic circuit.
