FWD 08 A correct pipe work installation is essential for trouble-free coil operation. Figures 13 and 14 show an example for 2

piping water coils. (The diagrams do not limit the type of control system used.)

To prevent coil damage:
FWD 10 2
3
• All pipe work must be supported independently from the coils, locating a flexible joint directly on the coil
1
connection.
FWD 12 2
3
• All connections must be made in such a way that the expansion and contraction of pipes do not impose forces on
1
the coil headers.
FWD 14 2
• Over tightening of coil connections must be avoided to prevent any damage to headers and header connections.

1
Control the correct direction of liquid flow as indicated on the unit nameplate. To ease all maintenance operations,
FWD 20 2
it is recommended to fit all coil connections with a flange/pipe assembly and a shut-off valve. To ensure thermal
3
efficiency and air vent, the pipe must be connected to the coil, as indicated on respective labels.
CAUTION! To avoid damaging the coil connections, it is essential to grip the union in a pipe wrench whilst applying
counter pressure to tighten the joint (see Figure 11).
