New DC inverter twin rotary compressor
■ Small torque change, good dynamic balance, the system runs stably,
little vibration, low noise, high efciency
■ More higher efciency in part load running
DC FAN MOTOR
Strong magnetic rotor, small vortex of refrigerant
Low noise level
Night quiet operation function
Noise can be reduced to 45dB (A)
Low noise operation
■ DC INVERTER compressor, smooth operation, no need frequent start the compressor, effectively reduce the
noise outdoor
■ Vector inverter control, more precise control
■ DC fan motor, motor bracket used the non-resonance structure, ensure smooth running of the motor, reduce
operating noise
■ Big diameter fan, design according to aviation quieter principle
DC motor
High reliability
Refrigerant automatically reclaim technology
Set refrigerant automatically reclaim through dip switch, the refrigerant in indoor and pipe can be automatically return to outdoor, convenient in maintenance and reducing waste of refrigerant, reduce customer
maintenance cost, improve the efciency of after-sales
maintenance

Notes
Please power off rstly for about 10 minutes
before checking control box, and make sure the voltage between P and N below 20V.
• Please check the power rstly before test, and make sure the crankcase heater powering on for 12 hours at least to protecting compressor.The switch BM1-1 is used for locking the indoor units number, the initial situation is "OFF". After power on, the display board will display【U**】,"**"indicates the number of indoor units that the outdoor unit can communicate with. If it can match the actual number of indoor units, please change "OFF" to "ON", or else x the communication problem rstly. Forbid connecting the power wire to the "P" and "Q", otherwise the control board will be damaged.Please make sure the earth wire connecting the grounding hole on the electric box rmly.

■ This manual should always be accessible and close to this air condition equipment.
■ There are two types of indications, "WARNING" and "CAUTION". The indication preventing from death
or heavy injury is listed as "WARNING". Even the indication listed as "CAUTION " may also cause serious
accident. Both of them are related to safety, and should be strictly followed.
■ After installation and start-up commissioning, please handover the manual to the user. The manual should be
well kept in safe place and close to the unit.
■ The installation or the maintenance should be performed by an authorized agency. The wrong operation of this air
condition equipment may cause water leakage, electric shock or re.
■ Please install the unit on the top of a solid foundation or structure which is strong enough to support the unit.
■ The installation of this air condition equipment should follow local construction codes.
■ Use the right cable size, secure the terminal rmly, organize the cables well and make sure no tension is added
on cables. Cable insulation should not be damaged. The incorrect installation may lead to overheat or re.
■ When installing or moving the unit, the refrigerant system should be vacuumed and recharged with R410A
refrigerant. If any other gas enters the system, it may lead to abnormal high pressure which may cause damage
or injury.
■
Please use the proper manifolds or branches during the system installation. The wrong parts may cause
refrigerant leakage.
■ Keep the drain pipe away from toxic gas vents to prevent possible pollution of indoor environment.
■ During or after the installation, please check whether there is refrigerant leakage. If any leakage, please take
any measures for ventilation. The refrigerant may be toxic at some concentration levels.
■ The unit is not explosion-proof. Please keep it away from ammable gases.
■ The drain pipe should be installed per this manual to ensure proper drainage. The pipe should be well insulated
to avoid condensation. Wrong installation may lead to water leakage.
Both liquid pipe and the gas pipe should be also well insulated. Not enough insulation may lead to system
performance deterioration or humidity formation.
■ This air condition equipment is not intended to be operated by persons with lack of experience and training,
unless they have supervision or instruction concerning use of this air condition equipment.
■ Please keep children away from this air condition equipment.
WARNING

Outdoor Installation
■ Grounding wire should be connected with the grounding bar. The grounding wire can not be connected to the gas
pipe, water pipe, lightening rod or the telephone grounding wire. Improper grounding may cause
electric shock.
■ Units installed on roof should have appropriate access and handrail.
■ Use the wrench to fasten the nut and are at proper torque. Excessive torque may cause ared section to broke
leading to refrigerant leakage.
■ After refrigerant pipe installation, please take nitrogen leakage test to avoid refrigerant leakage.
■ R410A is the only permitted refrigerant.
■ To avoid mischarging wrong refrigerant, the check valve diameter is changed for R410A. To strengthen the pipe,
the ared pipe dimension is also changed. Please use R410A specied tools as shown below.
R410A specied tools Remarks
1
Gauge manifold Range: HP >4.5MPa, LP >2MPa
2
Charge hose Pressure: HP:5.3MPa, LP:3.5MPa
3
Electronic weight for charging R410A No other means permitted
4
Torque wrench
5
Flare tool
6
Copper pipe gauge for adjusting projecting margin
7
Vacuum pump tting Vacuum pump must be equipped with check valve
8
Leakage detector Only Helium detector permitted
When charging refrigerant, the refrigerant must be in liquid state from the tank.
■ To prevent EMC interference on other appliances, please keep indoor unit, outdoor unit, power cable and
connecting wire at least 1m away from those appliances .
■ Fluorescent lamp (reverse phase or rapid start type) may interfere the remote controller's signal. Please install
indoor unit away from uorescent lamp. The farther the better.
For installation, please review the items below:
■ Is the connected units quantity and the total capacity in the allowable range?
■ Is the refrigerant pipe length in the limited range?
■ Is the pipe size proper? And if the pipe installed horizontally?
■ Is the branch pipe installed horizontally or vertically?
■ Is the additional refrigerant counted correctly and weighed by the standard balance?
■ Is there refrigerant leakage?
■ Is all the indoor power supplies can be on/off simultaneously?
■ Is the power voltage in compliance with the data marked on the rating label?
■ Is the address of indoors has been set?
CAUTION

Air-conditioner can't be installed in the place with inammable gas. Or it will cause re
hazard.
The unit should be installed at the place where the cold/hot air or noise will not interfere the neighbours.
The unit should be installed at the place with good ventilation. No obstacle at the air inlet/outlet. And no strong wind blows the unit. The installation space refers to the latter info.
The unit should be installed at the strong enough place. Or it will cause vibration and noise.
The place where the water can ow uently.
The place where no other heat source will affect the unit. Pay attention to the snow against clogging the outdoor. In installation, install the anti-vibration rubber between the unit and the bracket.
The unit is better not be installed at the below places, or it will cause damage. The place where there is corrosive gas (spa area etc). The place blowing salty air (seaside etc). Exists the strong coal smoke. The place with high humidity. The place where there is device emitting Hertzian waves. The place where voltage changes greatly.

(3) Transportation and hoisting
Hoisting
■ Please remove the outdoor unit to the installation location as far as possible near place befor open the packaging.
■ Forbid on the equipments to place anything, need to use 2 ropes while promoting outdoor.
■ Please according to following way hoisting outdoor:
■ Ensure that the outdoor unit when hosting the level to rise slowly.
■ Do not remove the packaging.
■ When hoisting do not have to tie up the elevator to the unit hits on the packaging and the outside wrapping.
■ When hoisting exterior must use the suitable protection.
Handling
Before the installation, outdoor do not deposit any material, otherwise likely has the re or the accident. When handling unit, please operate as shown in the following gure and note the following points
