3. Well sealed and heat preservation should be done for both wind pipe and circle flange pipe.
4. New wind should be the air after filtrate treatment.
Attention:
● There should be thermal insulation layers around the air delivery and air return ducts as well as on
the new air ducts to protect against heat losses and condensation. Adhere the plastic nails onto the
ducts, and then attach a layer of insulation cloth with the tinfoil onto the ducts. Fix the plastic nail
and then seal tightly the joints by way of tinfoil tapes. Some other materials with good thermal
insulation properties can also be used.
● The air delivery and air return ducts should be fixed to the prefabricated ceiling boards with iron
stands. The joints of the air ducts should be sealed tightly to prevent from air leakage.
● The designing and operation of the air ducts should comply with the related state standards and
procedures for engineering.
● It is recommended to leave at least a space of 150mm between the edge of the air return duct and
the wall, and a filter screen should be placed at the air return opening.
● Muffling and vibration reduction should be taken into consideration during the designing and
operation of the air ducts. In addition, the noise source should be kept away from the crowds. It is
absolutely not allowed to design the placement of the air return opening right above the head of the
users (in the offices, lounges or other public sites).
● Installation of Condensed Water Pipes
☆ The condensed water pipes should be kept at 5—10 degrees of gradient to facilitate discharge of the
condensed water. Thermal insulation materials should be placed at the joints of the condensed water
pipes so as to prevent from dew condensation. (As shown in Fig.11)
There is an outlet for condensed water on the left and right side of the indoor unit. When the outlet of
the condensed water is determined, the outlet on the opposite side should be blocked with a stopper and

☆ The outlet for condensed water on the right side is blocked with a stopper when the product leaves
the factory.
Attention: It must be made sure that there is no leakage at the joints of the condensed
water pipes.
●
Designing of the Drainage Pipelines
☆ The drainage pipes should be kept at a certain gradient (1/50—1/100) so as to avoid bulges of pipes
where there might be water bends.
☆ When connecting the drainage pipes with the unit, care must be taken not to exert too much force
on the pipelines of either side of the unit, and the pipes should be fixed as close to the unit as
possible.
☆ The drainage pipes can be the locally purchased hard PVC pipes for common purposes. When
making the connections, the end of the PVC pipe should be inserted into the drainage hole. Use
drainage hose and wire bondage to fix it tightly. It is not allowed to use adhesive glue to join the
drainage hole and the drainage tube.
☆ When the drainage pipeline is laid for a couple of units, the position of the shared pipeline should
be approximately 100mm lower than the drainage outlet of each unit. In this case, some
special-purpose pipes with thicker walls sill be used.
● Installation of Drainage Pipeline
1. Diameter of drainage pipe should not be less than that of connecting pipe.(PE pipes: size: outer
diameter 255mm; wall thickness ≥1.5mm)
2.
Drain pipe should be as short as possible and its gradient at least should be 1/100 in order to
avoid forming air pocket.
12
Install of ducted type indoor unit
3.
If there is no enough gradient for discharge hose, riser pipe for drainage should be installed.
4. In order to prevent the discharge hose from bending, mutual distance of hanger brackets
should be at least 1.-1.5mm.

5.
Insert discharge hose to drain outlet and then screw the pipe clamp up.
6.
For heat insulation, wrap the clamp of discharge hose with sponge.
7. Execute heat insulation to the indoor discharge hose.
●
Cautions of Riser Pipe for drainage
The installation height of riser pipe for drainage should less than 850mm.It should be perpendicular
to the unit and the distance between them should be less than 800mm.

Test of Drainage System
1.
Please test the drainage system after installation of electric appliances.
2.
During the test, check if the water correctly flows through the pipeline and observe the joints
to make sure that there is no leak. If the unit installs in new house, it is advised to execute the test
before decoration of the ceiling.
● Testing on the Drainage System
☆ Upon completion of the installation of the electric appliances, the testing on the drainage system
should be performed.
☆ During the testing, it should be made sure that the water flows through the pipeline in the correct
direction. Careful observations should be made on the joints to ensure that there is no leakage of
water at the joints.
☆ In the case that the unit is to be installed in a new building, it is recommended that the testing be
made prior to the decoration of the ceiling.

Specific function of each function DIP switch is as follows:
DIP switch 1（S/R）——Memory mode setting; it includes energized standby mode and energized
recovery mode. Energized standby mode is that: after the unit resumes power supply,
the previous setting parameters will be maintained but cannot automatically run and
such setting is factory setting (dialing the DIP switch to “ON” position); For example,
setting parameters of a indoor unit are high fan speed before de-energization and 24
and after resuming power supply, the unit will be in standby status; Then manually turn
on the unit and its parameters are still high fan speed and 24
. Energized recovery
mode is that: after the unit resumes power supply, not only it will keep the previous
setting but also can automatically run; But if the unit is in turnoff status before
de-energization, it will still be that status after resuming power supply.
15
Install of ducted type indoor unit
DIP switch 2（L/I）——Control mode; it includes wired control mode and remote control mode. Wired
control mode is that: control the running of indoor unit by wired controller, which
is factory setting (dialing the DIP switch to “ON” position); When the setting is
wired control mode, “Memory mode setting” and “Master/slave indoor unit
setting” of S7 are invalid which can be directly set on the wired controller. Remote
control mode is that: control the running of indoor unit by remote controller; when
the setting is remote control mode, its functional code must be set in S7.
DIP switch 3（M/S）——Master/slave indoor unit setting; it is master/slave setting of indoor unit
running mode, which is mainly used for people’ priority requirements (such as
leaders, patients, etc.). The factory setting is master indoor unit( dialing the DIP
switch to “ON” position). When settings of all indoor units are slave indoor units,
outdoor unit will run in the mode of firstly started slave indoor unit. If the mode
of later started slave indoor unit and mode of firstly started slave indoor unit
conflict, the conflict modes error will be warned by the system and later started
indoor unit cannot run. In that case, the running of the unit is decided by firstly
started slave indoor unit.
When there is only one indoor unit that is set to be master indoor unit, in that case,
no matter if the master indoor unit is firstly started, the conflict mode error will be
warned by slave indoor unit once the mode of slave indoor unit and the mode of
master indoor unit conflict (except for turnoff mode of master/slave indoor unit).
And the unit will firstly run at the mode of master indoor unit
When there are multi indoor units that are set to be master indoor units, the unit
will run at the mode of master indoor unit with min. address code. When the
indoor unit with min. address code changes to the running status from turnoff
status, modes of other master indoor units or slave indoor unit should be in the
same mode with it, or the conflict mode error will be warned. Therefore, when
there are multi master indoor units, set the address code from high to low
according to priority.
16
Install of ducted type indoor unit
DIP switch 4（I/O）——Collection point setting of ambient temp.; the setting is mainly used when there
is high differential between temperatures of air conditioning area and return air of
the unit. The setting is valid only when there is receiver and includes collection
points setting of temperatures of return air inlet e and receiver head. The factory
setting is the collection points setting of temperature of return air inlet( dialing the
DIP switch to the “ON” position.
DIP switch 5（L/H）——High-low static pressure setting of fan; it includes high static pressure setting
of fan and low static pressure setting of fan, which should be adjusted according to
the project.
Cautions:
