Reference of the Hydraulic Connections
* For the assembly of the hydraulic network it
is advisable to use a water filter, type "Y", at
the conditioner inlet or a temporary filter in
order to avoid the entrance of dirt that may
obstruct the coil.
* In order to prevent the destruction of the
coils, which are manufactured in copper, it is
necessary to adjust the thread with two pipe
wrenches. One of them performs the
adjustment and the other holds the copper
connection, leaning in the direction opposite
to the effort made to adjust the thread. See
drawing.
The hydraulic connections to the network
may be performed at any side. For that, mention
the desired side when ordering the equipment.
The connection gauges between the
conditioner and the network shall comply with
the pertinent regulations.
The piping shall be assembled in a way its
weight is supported by independent brackets.
Under no hypothesis the piping shall lean its
weight on the equipment.
The assembly of the hydraulic
interconnection shall be made in a way to allow
accessing the equipment.
It is recommended that the chilled water
hydraulic interconnection be made up of:
Supply:
