1 Safety Precautions
Means items that must be forbidden! Otherwise, it may lead to personal injury
or death or serious damage.
Means items that must be followed! Otherwise, it may lead to personal injury
or property loss.
Follow this instruction to
complete the installation
work. Please carefully
read this manual before
unit startup and service.
Installation should be
conducted by dealer or
qualified personnel. Please
do not attempt to install the
unit by yourself. Improper
handling may result in water
leakage, electric shock or
fire disaster etc.
Before installation, please
check if the power supply
is in accordance with the
requirements specified on
the nameplate. And also
take care of the power
safety.
Make sure the unit can be
earthed properly and
soundly after plugging into
the socket so as to avoid
electric shock. Please do
not connect the ground wire
to gas pipe, water pipe,
lightning rod or telephone
line.
Be sure to use the
exclusive accessory and
part to prevent the water
leakage, electric shock
and fire accidents.
If refrigerant leakage
happens during installation,
please ventilate
immediately. Poisonous gas
will emerge if the refrigerant
gas meets fire.
Wire size of power cord
should be large enough.
The damaged power cord
and connection wire
should be replaced by
exclusive cable.
After connecting the power
cord, please fix the electric
box cover properly in order
to avoid accident.
Never fail to comply with
the nitrogen charge
requirements. Charge
nitrogen when welding
pipes.
Never short-circuit or cancel
the pressure switch to
prevent unit damage.
Please firstly connect the
wired controller before
energization, otherwise
wired controller cannot be
used.
Before using the unit, please
check if the piping and
wiring are correct to avoid
water leakage, refrigerant
leakage, electric shock, or
fire etc.

Do not insert fingers or
objects into air outlet/inlet
grille.
Open the door and window
and keep good ventilation in
the room to avoid oxygen
deficit when the gas/oil
supplied heating equipment
is used.
Never start up or shut off
the air conditioner by
means of directly plug or
unplug the power cord.
Turn off the unit after it runs
at least five minutes;
otherwise it will influence oil
return of the compressor.
Do not allow children
operate this unit.
Do not operate this unit with
wet hands.
Turn off the unit or cut off
the power supply before
cleaning the unit,
otherwise electric shock
or injury may happen.
Never spray or flush water
towards unit, otherwise
malfunction or electric
shock may happen.
Do not expose the unit to
the moist or corrosive
circumstances.
Electrify the unit 8 hours
before operation. Please
switch on for 8 hours before
operation. Do not cut off the
power when 24 hours short-
time halting (to protect the
compressor).
Volatile liquid, such as
diluent or gas will damage
the unit appearance. Only
use soft cloth with a little
neutral detergent to clean
the outer casing of unit.
Under cooling mode, please
don't set the room
temperature too low and
keep the temperature
difference between indoor
and outdoor unit within 5.
If anything abnormal
happens (such as burning
smell), please power off
the unit and cut off the
main power supply, and
then immediately contact
ASAMI appointed service
center. If abnormality
keeps going, the unit
might be damaged and
lead to electric shock or
fire.
User is not allowed to repair
the unit. Fault service may
cause electric shock or fire
accidents. Please contact
ASAMI appointed service
center for help.

(4) Wrap the connection pipe and joint with sponge and then tie them firmly with tape.
4.3 Drainage Pipe Installation and Drainage System Testing
4.3.1 Notice for Installation of Drain Pipe
(1) The drainage pipe should be short and the gradient downwards should be at least
1%~2% in order to drain condensation water smoothly.
(2) The diameter of drainage hose should be bigger or equal to the diameter of drainage
pipe joint.
(3) Install drainage pipe according to the following fig and arrange insulation to the
drainage pipe. Improper installation may lead to water leakage and damp the furniture
and other things in the room.
(4) You can buy normal hard PVC pipe used as the drainage pipe. During connection,
insert the end of PVC pipe into the drainage hole and then tighten it with drainage hole
and wire binder. Can’t connect the drainage hole and drainage hole with glue.
(5) When the drainage pipelines are used for several units, the position of pipeline should

4.3.3 Test of Drainage System
(1) Please test drainage system after electric work is finished.
1) Inject approximately 1L purified water to drain pan from air vent, ensure that not to
splash the water over the electrical components (e.g. water pump. etc).
2) In case of commissioning finished, please energize the IDUs and switch to cooling or
dry mode, meanwhile, the water pump operates, you can check the draining through
the drain socket.
3) If communication wire is not connected, communication malfunction “C0” will occur
after 60s of energizing. In this case, the water pump operates automatically. Check if
the water pump drains normally through drainage port. The water pump will stop
automatically after running for 10mins.
(2) During the test, please carefully check the drainage joint, make sure no any leakage
occur.
(3) It is strongly recommend to do the drain test before ceiling decoration.
Fig 4.3.11
4.4 Installation of Air Duct
Note:
①There should be insulating layer on air-out duct, air-return duct and fresh air duct to
avoid heat loss and moisture. Adhere a nail on the air duct and then add thermal
sponge with a layer of tin. Fasten it with a nail cover and then seal the junction with tin
tapes. You can also use other materials that have good insulation quality.
②Each air-out duct and air-return duct should be fixed on a pre-made board with iron
frame. The junction of air duct should be well-sealed in order to prevent air leakage.
③The design and construction of air duct should comply with national requirements.
④The edge of air-return duct is suggested to be more than 150mm(5-7/8 in.) away from
the wall. Add a filter to the air-return opening.
⑤Please consider noise-damping and vibration damping for the design and construction
of air duct. Besides, noise source must be away from people. For instance, do not have
the air-return opening installed on top of the user (Offices, rest area, etc.).
