DESCRIPTION OF PRODUCTS & FEATURES

1.4 Products characteristic

The outdoor unit can match with different indoor unit

The indoor unit can be cassette type\convertible type and duct type. Due to its compact size it
neither breaks the harmonization of indoor decoration nor occupies the indoor spaces. The stylish
appearance of air conditioner allows it to blend right into ceiling.

Superbly efficient healthy filter

Superbly efficient antibiotic materials are utilized and can prevent germs from breeding efficiently.

Flexible and easy installation

Slim design with machine body, completely ceiling concealed and portable shape, all make it
greatly easier to install. Moreover, it occupies least constructional spaces, which help to reduce
constructional cost prices. It also features a specific drainage system with up to 600mm lift, which
allows reducing installation spaces and ensures to drain smoothly. Thanks to its "smudge-free"
mobile outlet grill, the ceiling can be protected from pollution effectively and allow the airflow to fit
people's comfortable need much more.
ESP can be from 0Pa to 50Pa; in the meantime, the duct unit is equipped with a filter and air return
box.

Auto-Restart function

When meeting a power failure during running, no matter how long it will be, once the power is
restored, air conditioner will automatic restart with the previous status.

Safety and reliable control due to various signal controls

1.Inputting with press buttons on the panel

2.Inputting with temperature sensors (indoor ambient temperature sensors, indoor coil pipe
temperature sensors)

3.Piping pressure signals

4.Compressor current signals

5.Testing signals

6.System time-shorten signal

7.Water overflowing signal

8.Communication signals between indoor unit and front plate or between indoor unit and outdoor
unit.

Universal convenient remote-controller

When using remote-controlling mode, it is comfortable and convenient to operate. The remote
controller is used as new style; it looks like a phone, very compact. It is a universal controller and
can be used for any unit such as single unit, multi free unit, MRV, etc. compatible with the old ones.

New wired controller

One wired controller can control 16 indoor units without any other device such as detector.

Silent design

The use of radial outward flow turbine fan produces large airflow volume and acts to significantly
decrease operating noise.

Low ambient temperature cooling function (optional)
Equipped with high/low pressure protection switch

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

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

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.

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

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

.

, the compressor and outdoor blowing

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.

9 INSTALLATION INSTRUCTIONS AND MAINTENANCE

9.1.cassette type

9.1.1 Installation tools

Preparation before installing convertible type unit

Before installation of convertible type unit, please confirm which type will be selected: in

the ceiling or on the floor.

There is a dial switch K1 on the PCB, if you select D, that means the installation is in the

ceiling. If you select L, that means installation position is on the floor.

In the ceiling mode, there will a 4 degrees temperature compensation in heating mode.

Because in heating mode, the warm air will rise and stay in higher position. If there is not

temperature compensation, when the set temperature has arrived, it may happen that the

air in higher position has become the set temperature, but the air in lower position has not

arrived the set temperature.

There is no different for the operation of swing and the heating capacity.

(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.
