7.1 - Water Coil Connections
Each water coil is equipped with headers having male
threaded type connection on water supply and water return
(see section "Dimensional data and weight of standard
units" for header connection sizes).
Air vent must be installed at highest point of the water
piping.
To ensure an optimum heat transfer efficiency, connections
of water supply and return should be arranged in such a
way that a counter flow configuration between air and water
is obtained.
Flexible hoses are recommended for coil connections in
order to ensure a free volume expansion of water pipings
To avoid any damage on coil, use two spanners to tighten
the water pipe fittings on each header.
This non-observation leads to the cancellation of the
warranty in case of damages caused to the coil.

and to avoid mechanical stresses on the units. Tighten
normally the water connections. Note that an excessive
tightening can cause too strong material stresses at the
time of significant temperature changes.
All water lines should be insulated to prevent sweating
and heat loss.
