ceiling.
5.5 Unit installation
5.5.1 Precautions
To ensure good installation and operation, do check the following items before installation of the
unit:
a) Adequate space shall be provided for installation and maintenance of the unit. Please refer to
Unit Dimensions in section 4.1. Removable ceiling panels or accesses shall be provided for
daily maintenance;
b) Determine locations of pipelines and electric wires before installation; and adequate fitting
space should be reserved.
c) Make sure hanging structure adequate to support the unit weight;
d) All units shall be leveled to ensure smooth water drain and proper operation;
e) Thermal insulation of chilled water valves and pipelines shall be made by the installer.
5.5.2 Unit mounting
a) Install a suspending bolt (M10 bolt)
To support the unit weight, anchor bolt shall be used in the case of already exists ceiling. For new
ceiling, use built-in type bolt or parts prepared in the field.
Before going on installing adjust space between ceilings.
*All above parts should be prepared in field.
b) Unit mounting
The unit is installed under the building ceiling with threaded rods to be provided by the customer.
- Determine the position of the drilled mounting holes according to the hanging hook dimension

FanCoilUnitOne-WayCassetteType
17

in section 4.1
- Provide the fixing for the threaded rods with suitable tools.
- Fasten the threaded rods to the building ceiling. The length dimensions depend on the
distance to the intermediate ceiling.
- Push the unit, with the terminal box facing front, into the intermediate ceiling at an angle, until
the unit is fully placed into the intermediate ceiling.
- Place the unit straight over the opening. Provisional fast installation is possible using the
hooks on the suspension lugs. After final positioning fix the straps to the unit wall using
tapping screws.
- Screw the unit firmly onto the threaded rods. Make sure that the unit is exactly horizontal.
5.5.3 Panel installation
NOTE!
- Check whether indoor unit is horizontal with leveler or polythene pipe filled with water,
and check that the dimension of the ceiling opening is correct. Take off the lever gauge
before install the panel.
The design panel with an air filter is not delivered pre-assembled. The required mounting material
(setscrews) is packed separately in a plastic bag.
- Loosen the air intake grille by turning each of the 2 locks.
- Remove the air intake grille. (Refer to below indication fig)
Install the panel board in the right direction, you can follow below steps.

FanCoilUnitOne-WayCassetteType
18

a) Make sure the right direction of panel in order that the installation holes on the panel is
corresponding to the unit, put two bolt in diagonal position ST4×10 and screw it but not tightly.
b) Connect wiring cable of stepping motor, display board to the elec. box and tidy up the wiring
cables.
c) Put the other two bolt in diagonal position ST4×10 and screw it to the main unit but not tightly.
d) Adjust the location and direction of panel to make air outlet frame and the drain pan wind way
acdordant.
e) Screw up the bolts tigthly and make sure the well match between unit and panel.
f) Install the air inlet grille opposite to the sequence when disamount the grille.
NOTE!
- The incorrect direction will result in water leakage, meanwhile swing and signal
receiving are displayed that cannot be connected.
- Please refer to section 5.7 before connect the cables.
- If screws are not tightening, problems in below Fig. might occur. Tighten screws
properly.
- If there is still space after tightening of screws, please readjust the height of indoor
unit.
5.6 Pipe connection
DANGER OF SCALDING BY ESCAPING
HEATING MEDIUM!
Before the on-site piping and the fan coil hydraulic connection is set up, the heating/cooling water
should be isolated and secured against being opened unintentionally.
NOTE!
- At the beginning of the fitting procedure, remove the caps on the water inlet and outlet
pipes.
- All on-site pipes by others for the cooling water must be insulated against condensate
formation.
- When all connections have been completed, all screw connections should be tightened
and checked that they are free of mechanical stress.
5.6.2 Valve connection
The units are supplied without valves, In case of installation with valves by others, the installation

FanCoilUnitOne-WayCassetteType
19

of the water inlet and outlet depends on the location of the water connection and/or the used
valves.
Below showed Fig. indicate the connection of a 2-way valve and 3-way valve to the units.
2-Wayvalve 3-Wayvalve
NOTE!
- In case of installation with motorized valve, it is necessary to short-connect the
connection port S6 on unit PCB; (If no motorized valve, then S6 should be open/cut off)
5.6.3 Water inlet/outlet pipe connection
- Connect the chilled water pipe to coil pipe by using 3/4" external thread connecter.
- Distinguish the inlet/outlet water according to the sign on the unit.
- Heat preservation must be used for the chilled water pipe, and pay attention to the end side
management of insulate material.
*Indicativefigof2pipesystem
5.6.4 Condensate water pipe connection
- Condensate pipe diameter shall be equal or larger than that of the fitxting of the unit. (Size:
20mm)
- Drain pipe should be short, with a downward slope at least 1/100 to prevent air bag from
happening.
- If downward slope can't be made, take other measures to lift it up.
- Keep a distance of 1-1.5m between suspending brackets, to make water hose straight.
