component for temperature control is designed to
control the opening/close of chilled water valve,
and generally provided with one dial for setting
temperature.
The three-speed switch is marked with
Off/High/Medium/Low for controlling the speed of
motor and thus adjusting air volume.
5.3 Air discharge When water flows in the system for the first time,
partial gas may remain in the coil and mainly
appear at the top of the coil. A manual vent valve
is installed on the top of water outlet adapter of
the coil. Rotate the valve's rotary knob to exhaust
when residual air in the coil makes abnormal
noise. If the rotary knob is too tight, use pliers to
rotate for one to two rounds anticlockwise, so as
to exhaust the air, until water flows out from the
vent valve steadily. After that, tighten up the rotary
knob.
