5.2- Piping Connections
Coils should be piped in counter flow arrangement to achieve required capacity. This arrangement requires
that the entering heating or cooling fluid contacts the air leaving the coil. Water heating and cooling coils
should be arranged with inlet connection at the lowest level on one side of the coil near downstream and
water outlet connection on the same side but at high level near the upstream. This arrangement drives any
air in the system into the upper part of the coil, where a manual air release valve should be fitted.
All coils connecting piping should be independently supported not to impose strain on the coil connections
or circuitry. All coils connecting piping should be thermally insulated
WARNING: Use a pipe wrench to restrain the pipe connections of the coil when tightening the external pipe
connections.
