Hydraulic connections
Preliminary instructions
The choice and installation of system components is left to the skilled
installer, who shall operate pursuant to the best practices and the
legislation from time to time in force.
Check that the pipes do not contain stones, sand, rust, debris or other
extraneous bodies that might damage the system.
It is appropriate to create a by-pass of the unit to make it possible to
wash the pipes without having to disconnect the unit.
The connection tubes must have the appropriate diameter and must
be supported, so as not to rest their weight on the unit.
Mandatory items:
Install a filter whose dimensions are appropriate for the impurities
present in the water entering the unit.
Install a flow meter for liquids, to be dimensioned and calibrated
according to the system’s hydraulic characteristics.
Install air venting valves in the highest points of the pipes.
Install flexible elastic joints to connect the pipes.
The flow meter must be positioned halfway through a stretch of
horizontal pipe with a length of at least 1 metre.
The system’s water content must prevent instabilities in the operation
of the refrigerating circuits.
Systems charges with anti-freezing agents or subject to special
regulations require the use of water disconnectors.
Failure to install filters, flow meter and anti-vibrating mounts can cause
obstruction, breakage and noise issues, for which the manufacturer
waives any liability.
Check charge losses from the unit, the system and any other in-line
mounted accessories.
The water flow must be maintained stable during operation.
The sealing of threads must be obtained using hemp and green paste.
Do not use Teflon when the unit contains anti-freeze liquid.

Do not use the heat pump to treat the water used by industrial
processes, in swimming pools or in the house. In all these cases, an
intermediate heat exchanger is required.
Condensate discharge connection
With conveying
Connect a drainage tube to the connector on the collector tray and run it
towards and appropriate discharge area.
Without conveying
- The drainage capacity increases if the pre-cut holes in the base are
open.
In case of installation in very cold areas or areas subject to heavy
snowfall, where freezing out is a possibility, foresee appropriate
antifreeze systems.
