5.2 Startup and operation The operation of fan coil unit can be controlled by

three-speed switch of motor or temperature

controller.

The temperature controller consists of one

three-speed switch of motor, one ON/OFF switch

and one component for temperature control. The

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.

► Disconnect power supply and remove wire

connected with motor, and stop fan blade

from rotating;

► Loosen set screw between side plate and

water collector;

► Remove water collector from unit shell,

and loosen the set screw between fixed

plate and side plate, Also loose the set

screw between side plate and top cover;

► Take out the heat exchanger on fan coil,

use hard nylon bristle to brush and wash

coil fins, and clear with vacuum cleaner;

► Reinstall the heat exchanger on fan coil

and water collector, and fix them with

screw;

► Connect electricity and water pipe, and

conduct test run to verify effects.

To reduce the frequency for cleaning coil, it is

better to equip unit with filter screen and clean

the screen on a regular basis.

• Water collector

The water collector must be clean to facilitate

removal of condensate water. And it must be

cleaned when showing dirt.

• Line collector

- Communication line must be connected to

Terminal Block through fixing clip.

- Communication line adopts metallic hose

for insulation.
