2.7 Hydraulic connections
FWXT
Pipeline diameter
The engineer is responsible for choosing the right water
lines and their size, in accordance with good installation
practices and the applicable laws, keeping in mind that
under-sized pipelines lead to poor system operation.
To make the connections:
- position the water lines
- tighten the connections using the "wrench against
wrench" method
- check for any fluid loss
- apply a lining to the connections (use proper insulating
material)
The hydraulic lines and fittings must be thermally insulated.
Avoid partial insulation of the pipes.
Avoid over-tightening the pipes to avoid damage to the
insulation.

To ensure water tightness of the threaded connections,
use hemp and green paste; the use of teflon tape is
recommended if you have poured anti-freeze liquid in the
water circuit.
Carefully check that the insulation is tight, in order to
prevent the formation and dripping of condensate.
Note: Always provide an electrically controlled valve
on the machine or upstream that interrupts the water
flow when the setpoint is reached.
