Close the input valve to each fan coil except the last coil (4). Turn the pump on and run it,
when the bubbles stop coming out of the discharge hose turn on the ball valve on coil (1), wait
for the bubbles to stop, then do the same for coil number (2), then (3). All CX Chillers are
required to have a flow switch installed in the loop. Air in the system may cause a flow switch
alarm; the controller will display a P5 or a P6 error code.
Proper and even flow through each fan coil is critical for both heating and cooling. This can be
done with flow meters or ball valves installed at each fan coil supply pipe. Set each fan coil to
the same temperature and fan speed. Using an accurate digital thermometer to adjust each
ball valve until the coil return temperatures are even. This can be done in cooling or heating
mode.
