2 Notices for use
2.1 Working principle for cooling
Principle:
The unit absorbs the air from the indoors and sends it away through circulation of cooling water,
so as to reduce indoor ambient temperature. Accordingly, the lower of temperature of the water is,
the larger of cooling capacity of the unit.
2.2 Working principle for heating
Principle:
Air circulation forced by the fan transfers the energy from hot water to the air indoors so as to

Cassette Type Fan Coil Unit Owner's Manual
4
increase indoor ambient temperature. Accordingly, the higher of temperature of the water is, the
larger of heating capacity of the unit.
2.3 Anti-cool-wind function
In order to ensure comfort of the users, under circumstances such as the heat mode just starts
or the unit runs heat mode under low water temperature, the fan will stop running to prevent the
chilled wind blowing out.
2.4 Anti-heat-wind function
In order to ensure comfort of the users, under circumstances such as the cool mode just starts
or the unit runs cool mode under hot water temperature, the fan will stop running to prevent the hot
wind blowing out.

4 Installation of the Cassette Type FCU
4.1 Schematic diagram of installation spaces
Ceiling
Fig.2
4.2 Selection of the installation location of the FCU
(1) Obstruction shall be put away from the intake or outlet vent of the FCU so that the airow can
be blown through all the room.
(2) Make sure that the installation comply with the requirement of the schematic diagram of
installation spaces.
(3) Select the place where it can stand 4 times of the weight of the FCU and would not increase the
operating noise and oscillate.
(4) The horizontally of the installation place should be guaranteed.
(5) Select the place where condensate water can drain out easily.
(6) Make sure that there are enough space for care and maintenance. Make sure that the height
between the FCU and ground is above 2500mm.
(7) When installing the steeve bolt, check if the installation place can stand the 4 times of the weigh
of the unit. If not, reinforce it before installation. (Refer to the install cardboard and nd where
should be reinforced)
Note!
①
There will be lots of lampblack and dust stuck on the acentric, heat exchanger and water
pump in dining room and kitchen, which would reduce the capacity of heat exchanger, lead to water
leakage and abnormal operation of the water pump. The following treatment should be taken under
this circumstance:
②
Ensure that the smoke trap above cooker has enough capacity to obviate lampblack to
prevent the indraft of the lampblack by the air conditioner.
③
Keep the air conditioner far from the kitchen so that the lampblack would not be taken in by

4.6 Installing drainage hose
NOTE:
♦Install the drainage hose.
♦Install the drainage hose with downward gradient (1/50 t0 1/100) and there should be no
rises or traps in the pipe.
♦Use general hard polyvinyl chloride pipe (VP25) [outside diameter l -1/4" (32mm)] and
connect it with adhesive (polyvinyf chloride) so that there is no leakage.
♦When the pipe is long, install supporters.
♦Always heat insulate the indoor side of the drainage hose.
♦When desiring a high drain pipe height, raise it up to 15" (400 mm) or less from the ceiling
within a range of 6" (150mm) from the body. T he raised height over this range will cause leakage.
Fig.9
4.7 Installation connecting the pipes
(1) Be sure to use both a spanner and wrench together as shown in the gure when connecting
or disconnecting pipes to/from the unit.
(2) The pipe af water-in/out is pipe thread G3/4".The surface of thread should be enlaced by the
two or three-circles trap
(3) After the water-in pipe and water-out pipe is connected tightly, start the water pump, and
then check its airproof performance.
(4) Insulate it as shown in the gure below.
(5) Use sealing pad (12) to wrap the water-in/out pipe and the insulation (10).
