SAFETY PRECAUTIONS
3 SAFETY PRECAUTIONS
Please read these "Safety Precautions" first then accurately execute the installation work.
Though the precautionary points indicated herein are divided under two headings,
WARNING and
CAUTION those points which are related to the strong possibility of an installation done in error
resulting in death or serious injury are listed in the WARNING section. However, there is also a
possibility of serious consequences in relationship to the points listed in the CAUTION section as well.
In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned.
After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please
explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner's
manual.
Moreover, ask the customer to keep this sheet together with the owner's manual.
WARNING
This system should be applied to places of office, restaurant, residence and the like. Appliaction to inferior
environment such as engineering shop could cause equipment malfunction.
Please entrust installation to either the company which sold you the equipment or to a professional contractor.
Defects from improper installations can be the cause of water leakage, electric shocks and fires.
Execute the installation accurately, based on following the installation manual. Again, improper installations can
result in water leakage, electric shocks and fires.
When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned
countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration.
In regards to preparing this countermeasure, consult with the company from which you purchased the equipment,
and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold
concentration does occur,there is the danger of a resultant oxygen deficiency accident.
For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient,
injury can result from a falling of the unit.
Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and
hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit.
For electrical work, please see that a licensed electrician executes the work while following the safety standards
related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive
use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of electric shocks and
fires.
Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to
the terminal connection part, through properly securing it. Improper connection or securing can result in heat
generation or fire.
Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can
also result in heat generation or fire.

SAFETY PRECAUTIONS
WARNING
When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated
refrigerant (please see nameplate) within the refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this
company can result in water leakage, electric shock, fire and refigerant leakage.
The position of indoor unit must be above the floor 2.5m.
CAUTION
Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightening rod or a telephone
ground wire.
Improper placement of ground wires can result in electric shock.
The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not
installing an earth leakage breaker may result in electric shock.
Do not install the unit where there is a concern about leakage of combustible gas.
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.
For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to
prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

(6) Plug in the power cord plug firmly. If the receptacle is loose, repair it before using the room air conditioner.
(7) Do not turn on the power until all installation work is done.
Be careful not to scratch the room air conditioner when handing it.
After installation, explain correct operation to the customer, according to the operating manual.
Let the customer keep this installation manual because it will be used when the room air conditioner is serviced
or moved.
SELECTING THE MOUNTING POSITION
WARNING
Install at a place that can withstand the weight of the
indoor and outdoor units and install positively so that
the units will not topple or fall.
CAUTION
(1)Do not install where there is the danger of combustible gas leakage.
(2) Do not install near heat sources.
(3) If children under 10 years old may approach the
unit, take preventive measures so that they cannot reach the unit.
Decide the mounting position with the customer
as follows:
1. INDOOR UNIT
(1) Install the indoor unit level on a strong wall, floor, ceiling
which is not subject to vibration.
(2) The inlet and outlet ports should not be obstructed: the
air should be able to blow all over the room.
(3) Install the unit near an electric outlet or special branch
circuit.
(4) Do not install the unit where it will be exposed to direct
sunlight.
(5) Install the unit where connection to the outdoor unit is
easy.
(6) Install the unit where the drain pipe can be easily installed.
(7) Take servicing, etc. into consideration and leave the
spaces shown in Fig.1. Also install the unit where the filter
can be removed.
NOTE: The appearance may be different from models.
2. OUTDOOR UNIT
WARNING
(1) Install the unit where it will not be tilted by more than 5•
(2) When installing the outdoor unit where it may be
exposed to the strong wind, fasten it securely.
(1) If possible, do not install the unit where it will be
exposed to direct sunlight.(If necessary, install a
blind that does not interfere with the air flow.)
(2) Install the outdoor unit in a place where it will be
free from being dirty or getting wet by rain as much
as possible.
(3) Install the unit where connection to the indoor unit
is easy.
(4) During heating operation, drain water flows from
the outdoor unit. Therefore, install the outdoor unit
in a place where the drain water flow will not be
obstructed.(Reverse cycle model only)
(5) Do not place animals and plants in the path of the
warm air.
(6) Take the weight of the air conditioner into account
and select a place where noise and vibration are
small.
(7) Select a place where the warm air and noise from
the air conditioner do not disturb neighbors.

(4) Cutoff protection against overload and overheat
During heating program, if the indoor blowing fan has been started and the compressor
has been running more than 2 minutes, and the temperature of indoor coil pipe (Ticp)
> 64 , the outdoor blowing fan will stops running; If Ticp ≤ 50
and the outdoor
blowing fan has kept stop state for 45 seconds, then it will restore rotation; If Ticp > 67
and such temperature has last for 10 seconds, the compressor will stop running and
indoor blowing fan run according to conditions as it reaches setting temperature. When
Ticp < 58 , and the compressor has kept stop state over 3 minutes, then the
compressor and outdoor blowing fan will restore normal running.
Cutoff protection for heating current
After 60 seconds from the compressor being started, if CT current exceeds I1 (9.2A) and
such case has kept 5 seconds, the outdoor blowing fan will stop. If 45 seconds has passed
after the outdoor blowing stops and the current of the compressor is less than I2 (7.5A), the
blowing fan will restore running. If CT current exceeds I3 (14.3A) and such case lasts for 3
seconds, the compressor and outdoor blowing fan will stop. The compressor will not restore
running until 3 minutes passes with CT current less than 12A.
(5) Cool wind prevention during heating program
At the first time entering heating program or after ending the latest frost removal, if the
temperature of indoor coil pipe (Ticp) < 28 , the indoor blowing fan will stop running; If
28
Ticp < 38 , the indoor blowing fan will run at low speed; If Ticp > 38
or the
compressor has been running for more than 4 minutes, the indoor blowing fan will run at

blowing fan does not enter overheat mode in 10 minutes after it is restarted, the
compressor has run over 45 minutes totally while 20 minutes continuously, and the
temperature of indoor coil pipe is lower than 43 ;
B
After the compressor continuously running for 20 minutes, the temperature of indoor
coil pipe falls 1 every 6 minutes and such case continuously appears three times,
and the temperature of indoor coil pipe is less than 40 , and 5 minutes have passed
after the compressor is restarted;
C
The compressor has run totally over 3 hours while 20 minutes continuously, and the
temperature of indoor coil pipe is less than 40 ;
D
The difference between room temperature and the one of indoor coil pipe is less than
16
and the compressor has totally run over 45 minutes while 20 minutes
continuously;
Frost removal will start if any one of the above conditions is satisfied.
Ending conditions for frost removal:
1 Time of frost removal has exceeded 9 minutes;
2 CT current exceeds I4(8.2A)
Actions of each load after the frost removal starts:
The compressor and outdoor blowing fan stop, and indoor blowing fan also stops.
55 seconds later the reversal valve is closed and next 5 seconds later the compressor is
started.
Actions of each load after the frost removal ends:
The compressor stops running while outdoor blowing fan immediately runs at high
speed, 55 seconds later the reversal valve is opened and next 5 seconds later the
compressor restores running and indoor blowing fan runs as conditions for cool wind
prevention.
(8) Freeze protection
After the compressor has run for 9 minutes, the system will check temperature of
indoor coil pipe (Ticp). If Ticp is less than -1 , the compressor and outdoor blowing
fan will stop. They will run again after the compressor stops if both the following
conditions are satisfied:
1) 3 minutes have passed since compressor stops.
2) Ticp exceeds 7 .
(9) 3 minutes protection for compressor
After compressor stops, it cannot be started until 3 minutes later. During the machine’s
running, if time after loosing power not exceeds 3 minutes, the compressor cannot be
ELECTRICAL CONTROL FUNCTIONS
restarted until 3 minutes later after it is reenergized.
10 Power breakdown memory
If the machine suddenly loses power while running, or stops for maintenance or trouble
shooting, it will restart running as the status when it stops after the power is restored.
Note: 1. Function setting: Continuously press sleep button on the remote controller 10
times in 5 seconds and buzzer on control panel shall beep 4 times.
2. Memory content: Running mode, wind speed setting, temperature setting,
swing status.
3. Cancel: Press sleep button on the remote controller 10 times and buzzer on
control panel beeps 2 times.
(11) Control of water pump
a. In cooling (including automatic cooling mode) and dehumidifying modes, the water
pump works if the compressor runs while stops 5 minutes later after the compressor
stops.
b. When water tank is fully filled, the float switch will be off. The water pump will start
to work after a controller has detected this signal and it will continue working for 5
minutes after the float restores to normal state.
c. If the full water signal is detected continuously over 5 minutes, the water pump
indicator lamp will flash to alarm and compressor stops running. The water pump
will run 5 minutes, then pause for 5 seconds before next 5 minutes’ running, ... until
the float restores to normal state, after which the pump will run for 5 minutes then
stop.
(12) Monitoring of remote network
Through preset interface, the air conditioner is connected to remote control detector
(made by Haier) with 2-core cables for wire communication, to execute instructions sent
from computer or centralized controller via remote control detector and meanwhile send
present running status and trouble information of the machine to remote control detector.
Connection between air conditioner and remote control detector:

(13) Trial run
Under shut-down state, hold pressing mandatory button. The buzzer will beep once,
then twice after 5 seconds. Release the button to enter mandatory cooling mode, under
which the indoor blowing fan runs at high speed with both the compressor and outdoor
blowing fan working. Press the mandatory button again can end the mandatory mode.
ELECTRICAL CONTROL FUNCTIONS
9.2 Introduction to the fan speed controller
210V
60V

42
The low ambient temperature cooling system realizes starting normally at the
by the method of: The sensor collects the coil temperature to change
temperature -15
the voltage of the outdoor fan motor, thus to change the fan speed. As a result, the system
pressure is restricted.
1.When the coil temperature exceeds 42 ,the voltage would be the highest value
210V and the fan motor runs in the normal way. As the outdoor temperature descends, the
condensator temperature descends too, and the pressure of the compressor discharge
lowers. The voltage of the fan motor falls along with the coil temperature. According to the
above chart (the coil temperature descends, the fan speed descends too), when the
temperature falls to 39 , the fan motor runs in the lowest voltage 60V, and if the
temperature falls continuously to 27 , the outdoor fan motor stops.
2.When the fan motor stops, the pressure of the compressor discharge rises
gradually, and also the condensator temperature. If the temperature rises to 35 , the
outdoor fan motor starts and runs in the lowest voltage 60V. If the condensator
temperature can not stop rising, when it is 39 , the fan speed will rise according to the
line in the above chart until the temperature be 42 , and then the fan motor will run in the
normal way.
