HYDRAULIC CONNECTIONS
The hydraulic connections have to be installed in accordance with national and local regulations; pipes can be made up of steel,
galvanized steel or PVC. Pipes have to be designed depending on the nominal water flow and on the hydraulic pressure drops of
the system. All the hydraulic connections must to be insulated with closed-cell material of adequate thickness. Chillers have to be
connected to piping by means of flexible joints. The hydraulic circuit should include the following components:
•
Hole thermometers for monitoring the hydraulic circuit’s temperature.
•
Manual gate valves to separate the chiller from the hydraulic circuit.
•
Y-shaped metallic filter (to be mounted on the return pipe from the plant) with a metallic mesh not larger than 1mm.
•
Loading group and discharge valve, where it’s necessary.
WARNING: Make sure that, when designing the pipe length and diameter do not exceed the maximum head loss on
the plant side, please see the technical data (available head pressure).
WARNING: An air vent valve should be always installed at the high point of the plant system.
WARNING: In the models of i-HP series, the expansion vessel is not integrated on the plant side. The actual capacity of
plant circuit should be checked by the installer in order to provide an expansion tank with adequate volume.
WARNING: Connect the pipes to the attacks by using always key against key system.
WARNING: Unit water inlet pipe have to be in correspondence with the connection labelled: ”WATER INLET”, otherwise
the evaporator may freeze.
WARNING: It is compulsory to install on the WATER INLET connection a metallic filter with a mesh not larger than 1mm.
Should the water flow switch be altered or should the filter not be installed, the warranty will no longer be valid. The
filter have to be kept clean, so make sure it is clean after the unit has been installed, and then check it periodically.
All units are standard supplied with the water flow switch (factory installed). Should the water flow switch be altered,
removed, or should the water filter not be installed on the unit, the warranty will be invalidated. Please refer to the
wiring diagram for the water flow switch electric connections.
The water on the charging/topping up pipe must be opportunely pre-filtered from any suspended particles and
