1. Introduction
Fan coil unit is a kind of compound device which assemble fan and surface-type coil heating-exchanger
together. Fan coil with fresh air supply system is a main type of center air-conditioner system, so it is an
important component of AC devices. Fan coil has horizontal type, vertical type, etc. A cooling (heating)
supply system usually consists of fan coil terminals and chilled water system (heated water system).
CHIGO commercial AC fan coil is designed and manufactured on the base of advanced technology, and
utilize qualified galvanized iron as material. Due to its supper-thin design, it has such advantages: beautiful
outlook, space saving, easy installation, etc. And the most obvious advantage is that it can decrease the
outlet air Temp-difference as low as possible to make room more comfortable, as well as don’t decrease
cooling capacity output. For the large air flow volume design, it can increase room ventilation frequency,
supply more flesh air, and balance room temperature distribution. Benefiting from adoption of advanced
material and technology, it can effectively decrease the running noise and keep running smoothly. With the
advantages above, it can be widely applied in market, hospital, office building, hotel airport, etc..

Part 9 Unit installation
9.1 Installation place
There is enough room for installation and maintenance.
The ceiling is horizontal, and its structure can endure the weight of the indoor unit.
The air outlet and the air inlet are not impeded, and the influence of external air is the least.
The air flow can reach throughout the room.
The connecting pipe and drainpipe could be extracted out easily.
There is no direct radiation from heaters
Caution
Location in the following places may cause malfunction of the machine. (If unavoidable, please consult
your local dealer.)
1. There exists petrolatum.
2. There is salty air surrounding (near the coast).
3. There is caustic gas (the sulfide, for example) existing in the air (near a hot spring).
4. The Volt vibrates violently (in the factories).
9.2 Install the Main Body
Please refer to the following figure for the hanging screw bolts.
Please install with Ø10 hanging screw bolts.
The handling to the ceiling varies from the constructions,
Consult the construction person for the specific condition.
1. The size of the ceiling to be handled------ Do keep the ceiling flat. Consolidate the roof beam for possible
vibration.
2. Cut off the roof beam.
3. Strengthen the place that has been cut off, and consolidate the roof beam.
Carry out the pipe and line operation in the ceiling after finishing the installation of the main body. While
choosing where to start the operation, determine the direction of the pipes to be drawn out. Especially in
case there is a ceiling, position the water refrigerant pipes, drain pipes, indoor lines to the connection
places before hanging up the machine.
The installation of hanging screw bolts.

CHIGO CAC-FAN COIL
Suspending the indoor unit
1.Use tools such as pulleys to hoist the indoor unit to the pendant bolt.
2.Use tools such as gradient to settle the indoor unit horizontally. Lack of horizontality may cause water
leak.
Pipe Connecting
1.The water vent is with the air outlet valve; the other side is air inlet.
2.When connecting the water collecting box, the torque is 6180~7540N.cm (630~770kgf.cm).
3.Put the connecting tubing at the proper position, wrench the nuts with hands, then fasten it with a wrench.
(Refer to Figure 6)
Figure 6
9.3 Connect the Drainage Pipe
1. Install indoor unit drain pipe
The outlet has PTI screw bread, please use sealing materials and pipe sheath (fitting) when connecting
PVC pipes.
CAUTIONS:
The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as the connections of
the indoor unit.

CHIGO CAC-FAN COIL
Hard PVC binder must be used for pipe connection, and make sure there is no leakage. With the
connection part to the indoor unit, please be noted not to impose pressure on the side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100, there should not be any winding.
The total length of the drain pipe when pulled out traverse shall not exceed 20m, when the pipe is over long,
a prop stand must be installed to prevent winding.
Refer to the figures on the right for the installation of the pipes.
2. Drainage test
Check whether the drainpipe is unhindered
New built house should have this test done before paving the ceiling.
9.4 Wiring Installation
The connecting diagram refers to the wiring diagrams.
