Coil Venting
When water is first introduced into a
coil, air is sometime trapped in the
coil tube. This trapped air has a
tendency to collect at the highest
point in the coil. When there appears
to be air trapped in the coil, resulting
in “bubbling” or “clanking” noises
within the unit. Therefore, a manual air
vent is installed at the highest point of
the header as shown in Figure 6.
To release air from the manual air vent
by rotating the knob. A pair of pliers
can be used if the knob is too tight to
turn by hand. Turn knob counter
clockwise 1-2 turns and allow air to
flow out of the air vent until a steady
stream of water appears. Then
retighten knob.
