6.5 WATER CONNECTIONS

1
For the hydraulic connections of the fan coil, use only suitable material and follow
2
the prescriptions of the system (project and rules of the Country of installation).
3
Female thread water connections of 1/2" are used on all YORK fan coil units. Unless other-
wise specified by the customer, these connections are located on the right side of the unit
(as viewed from the front when the fan coil has been installed). The connections can be
4
easily reversed on site (see section 7.4.1 of this manual).
The flow direction for each model is indicated on Encl. 2.
To facilitate installation and maintenance, we recommend that shut-off valves be installed
5
on the intake and outlet pipes. Also, install a Y-filter between the heat exchanger and the
gate valve on the intake (see Fig. 2, Enclosure 4 of this manual).
6
If the unit has been provided with valves, the flow direction printed on the body
valves must be respected.
7
On the inner side of the unit, an antitorsion structure near
the coil connections avoids the headers deformation while
connecting the unit to the system. It is recommended to pay
8
attention not to exert excessive force when tightening the
connections and eventually to use double spanners, to
avoid an overtightening and irreparable damage to
9
the coil. The coils are provided with an air vent, accessible
by using a screwdriver trough the holes on the side of the
inner frame.
10
All fan coil units are supplied with an auxiliary drain pan (supplied loose), which must be
installed close to the water connections (Fig. 6 and 6a).
