lMake sure that the unit has been switched OFF before
installing or servicing the unit.
lThe unit is widely used together with central HVAC system in
hotel, hospital, medicine factory, theater, commercial building,
office building, enterprises, chemical industry, exhibition room,
research institutes and so on.
lThe installation, commissioning and maintenance of these
machines should be performed by qualified personnel having a good
knowledge of standards and local regulations, as well as experience
of this type of equipment.
lMake sure that the rated voltage of the unit corresponds to
that of the name plate before commencing wiring work
according to the wiring diagram.
lThe unit must be GROUNDED to prevent possible hazard
due to insulation failure.
lKeep the unit away from any combustible or corrosive
environment.

l Disconnect the power plug when the fan coil is not going to
be used for a long time. Otherwise dirt may gather and cause
low efficiency.
l Make sure the air inlets and outlets of the unit are not
blocked.

Heat Exchanger
Fan Coil
The fan coil unit has no energy by itself but provides heating or
with hot or chilled water from central water supply system(heat
pump or chiller etc) .The fan of the unit blows through the heat
exchanger to cool or heat the air in the room.
If inlet water is cool, set the unit to cooling mode, the air outlet is
cool air.
If inlet water is hot, set the unit to heating mode, the air outlet is
hot air.
The unit is characterized with energy-saving, high efficiency,
low noise, reliable and convenient to select and install.

Select installation location with following considerations;
1. The return and supply air should be free from any
obstruction.
2. The wall which the unit is to be mounted on should be
stiff enough not to resonate and produce much noise.
3. Ensure the clearance on every side of the unit conforms to
figures as shown below.

If the central water supply system is indoor, and the drain

not need to drill a hole for piping to outside directly and
connect the water inlet and outlet piping to indoor water
supply system.
It’s recommended if the ambient temp. is lower than 0

③.Ionizer should be turned off when the unit is shutdown.
● The unit without motorized valve but with Ionizer
When the set termperature is reached, the fan stops. the fan
motor will restart 30 seconds for every 10 minutes(at super low
speed) and check the room temp. ( Tr).
When The set temp. Ts≤Tr+ 1 (cooling mode) or Ts ≥
Tr+1( heating mode) , the fan motor keeps running.
When Ts≥Tr+1（cooling mode）or Ts≤Tr+1（heating mode), the
fan motor stops.
The unit with motorized valve:
1. When the unit is turned on by remote controller, the water valve
switches on. When the unit is turned off, this valve switches off.
2. In heating mode, when Ts ≥Tr+1 , water valve switches on,
when Ts≤Tr+1 , water valve switches off. This program is
opposite in cooling mode.
●
● Fan motor's operation without motorized valve
A). Sensor failure and protection
①.If Room Temp. Sensor fails, the room temperature setting
will be invalid.
②.If Indoor Coil Temp. sensor fails, the protection on
improper operation for cooling or heating operation will be
invalid. While anti- cold air program operates as in Timer
Mode for 30 seconds.
B). Failure of PG motor (for 9000/12000btu/h unit)
When there is no feedback from the fan motor in 15 seconds
after it is turned on, the controller will regard it as in
malfunction, and will sen out a power (8 0% or 1 00% of the
rated power) to drive this fan motor. Error code E7 will be
displayed in the LED screen, and indoor fan speed can not be
adjusted with remote controller.
When there is a power failure during operation, and then the
power resumes, the unit will restart automatically operating as
per the operation modes, setting temperature, setting fan speed
and airflow direction, timer operation before the power failure.
