COMMISSIONING
1.
Ensure that the fan coil unit is clean, and the
filter especially is clean and free from dust.
Check the fastness of all access panels and
ductwork connections.
2.
Check that all electrical connections are correct
and comply with BS7671 and local bye-laws.
Refer to the wiring diagram supplied with the
fan coil unit
3.
Check the coil connections and drip tray
connections for leaks. Refer to Table 3 for coil
test and working pressures.
4.
Purge air from both heating and cooling
sections of the coil using the manual air vents
fitted.
5.
Balance the water flow rate through both hot
and chilled water systems following accepted
practice to achieve the specified flow rates.
6.
On AC motor units, there are two fan speed
switches - one to give three main speeds, and
the other to provide a 'fine-adjust' to each
speed. Set the switches to the specified design
settings, as highlighted on the label fixed to the
plenum access panel.
(Refer to diagram 8 for fan switch settings)
For further information on any fan coil unit - contact Dunham-Bush, quoting the serial number on the label on
the access panel.

On EC motor units, adjust potentiometer to
ensure air volume to design specification. If
using a BMS controller with a 0-10V output,

If fitted, set any remote switches and/or controls
to the specified settings.
9.
Check the operation of controls in accordance
with control manufacturer's instructions.
