Fan Coil Unit Wall Mounted Type
1. Product Introduction
1.1 Working Principle
The cold (hot) water entering the heat exchanger will do heat exchanging with air passing through the
surface of the heat exchanger to condition the air temperature and humidity. There is no (cold) hot source
for this product itself. The running mode depends on the environment temperature and the running mode of
the main unit.
Protection against hot air
Under the cooling mode, when the water temperature is too high, the fan will be stopped to avoid the
unit from blowing out hot air.
Protection against cold air
Under the heating mode, when the water temperature is too low, the fan will be stopped to avoid the unit
from blowing out cold air.
Memory function
Upon power failure, some statuses can be memorized, including: mode setting, fan speed setting, fan
swing setting, temperature setting etc.
1.2 Main Parts
Fig. 1

Fan Coil Unit Wall Mounted Type
1.3 Working Conditions
(1) The entering water temperature for cooling is suggested to be no less than 5℃,otherwise it woule lead
to condensate; the entering water temperature for heating is suggested to be not higher than 60 ℃,
otherwise it would lead to corrosion of copper tubes or abnormal noise.
(2) The suggested working environment temperature for cooling ranges 16 ～40℃and ranges 10 ～30℃
for heating. Beside, the relative humidity is or less than 80%.
(3) This product is a kind of comfort air conditioning, and is not allowed to be installed where there are
corrosive, explosive and inammable substances or smog; otherwise it would lead to operation failure,
shortened service life, ve hazard or even severe injuries. Special air conditions are required for where
mentioned above.
(4) The A-weighted sound pressure level is below 70dB.
(5) The temperature exchange efciency and enthalpy exchange efciency are tested under these testing
conditions as below:
yCooling capacity: air 27°C DB , 19°C WB, water temperature intake 7°C, outlet 12°C.
yHeating capacity: air 20°C DB , For the tow-row coils applicable to EU, the entering/leaving water
temperature is 45°C and 40°C; and for the four-row coils, the entering/leaving water temperature is
65°C/55°C.
yFreeze-up : air 27°C DB, 24°C WB , water temperature 6°C intake , 10°C outlet .
ySound power level according to ISO 5151. Sound pressure level are calculated at the below of air-
outlet 1m and 1m distance. The noise are tested before leaving factory.

2.2 Installation of the Rear Panel
(1) Always mount the rear panel horizontally. Due to the water tray of the unit has been adopted the both-
way drainage design, the outlet of water tray should be adjusted slightly down when installing, that is
to take the outlet of the water tray as the center of a circle, the included angle between the evaporator
and level should be 0 or more, that is good for condensing water drainage.

(2) Fix the rear panel on the wall with screws. (Where is pre-covered with plastic granula)
(3) Be sure that the rear panel has been xed rmly enough to withstand the weight of an adult of 60kg,
further more, the weight should be evenly shared by each screw.
2.3 Piping Holes for Installation
(1) Make the piping hole (Ф55) in the wall at a slight downward slant to the outdoor side.
(2) Insert the piping-hole sleeve into the hole to prevent the connection piping from being damaged when
passing through the hole.

2.4 Installation of the Drain Pipe
(1) For smooth draining, the drain hose should be placed at a downward slant.
(2) Do not wrench or bend the drain hose or ood its end by water.
(3) When the long drainage hose passing through indoor,should wrap the insulation materials.

2.4.1 The piping can be lead out from left, left rear.
(1) When routing the piping and wiring from the left side of the unit, cut off the tailings from the chassis in
necessary (as shown in Fig.6).
yCut off the tailings 1 when routing the wiring only;
yCut off the tailings 1 and tailings 2 when routing both the wiring and piping.
(2) Take out the piping from body case, wrap the piping electric wire, water pipe with tape and pull them
through the piping hole (as shown in Fig.7).
(3) Hange the mounting slots of the FCU on the upper tabs of the rear panel and check if it is rm enough
(as show in Fig.8).

2.5 Installation of the Connection Pipe
(1) Align the center of the piping pipe with the relevant valve.
(2) Place the nut, spring washer, washer, O-ring cross the pipe sequentially, and keep them tightly close to
each other with a distance of 6-7mm from the O-ring to the pipe end.
(3) Screw in the pipe nut by hand and then tighten the nut with spanner.
(4) If supplied by the manufacturer, the connection pipe shall be installed in place so as to guarantee the
reliable connection.

2.6 Installation of the Water Damper
All units must be equipped with a motorized valve because of the following main reasons.
(1) There would be a water ood risk for some units without motorized valves in the event that they stop
under the cooling conditions.
(2) Under the cooling and heating conditions, energy loss would happen to the chilled water and hot water.
Notes:
(a) The pipe must be wrapped by heat insulation material to prevent condensing water drips.
(b) It is prohibited to bind directly the water valve wire and sponge up with the copper tube, as there would
be probably a short circuit or even electric leakage. The right way is letting the water valve wire go
through the pipe sleeve and then binding the sponge and pipe sleeve.
(c) It is prohibited to put the valve core upside down.
2.7 Electric Wiring
2.7.1 Safety Precautions for Electric Appliances
(1) A dedicated power supply circuit should be used in accordance with local electrical safety regulations.
(2) Don't drag the power cord with excessive force.
(3) The unit should be reliably earthed and connected to an exclusive earth device by the professionals.
(4) The air switch must have the functions of magnetic tripping and heat tripping to prevent short circuit
and overload.
(5) The minimum distance between the unit and combustive surface is 1.5m.
(6) The appliance shall be installed in accordance with national wiring regulations.
(7) An all-pole disconnection switch with a contact separation of at least 3mm in all poles should be
connected in xed wiring.
NOTE
• Make sure the live wire, neutral wire and earth wire in the family power socket are properly connected.
There should be reliable circuit in the diagram.
• Inadequate or incorrect electrical connections may cause electric shock or re.
2.7.2 Earthing Requirements
(1) The FCU is type Ⅰelectric appliance. Please ensure that the unit is reliably earthed.
(2) The yellow-green wire in air conditioner is the earthing wire which can not be used for other purposes.
Improper earthing may cause electric shock.
(3) The earth resistance should accord to the national criterion.
34

Fan Coil Unit Wall Mounted Type
(4) The power must have reliable earthing terminal. Please do not connect the earthingwire with the
following:
①Water pipe ②Gas pipe ③Contamination pipe ④Other place that professional personnel
consider is unreliable
(5) The model and rated values of fuses should accord with the silk print on fuse cover or related PCB.
2.7.3 Connection of the electric wire
When connecting the electric wire if the wire length is not enough, please contact with the authorized
service shop to buy a exclusive electric wire that is long enough and the joint on the wire are not allowed.
(1) The electric wiring must be correctly connected, wrong connection may cause spare parts malfunction.
(2) Tighten the terminal screw in order to prevent loose.
(3) After tighten the screw, slight pull the wire and conrm whether is it rm or not.
(4) If the earth wire is wrong connection, that may cause electric shock.
(5) The cover plate must be xed, and tighten the connection wire, if it is poor installed, that the dust,
moisture may enter in or the connection terminal will be affected by outside force, and will cause re or
electric shock.

4.1 Error List
CAUTION
The FCU is not expected to be serviced by users. Incorrect repair may cause electric shock or re,
so please contact an authorized service center for professional service. The following checks prior to
contact may save your time and money.
Phenomenon Troubleshooting
The unit does not operate:
•Blow of fuse or breaker
•Power cut
•Don’t connect with power
• Low batteries of wireless remote controller
•Wireless remote controller exceed remote control area
Odours are emitted:
