The noise level will be measured in the third octave band limited values, using a Real Time Analyser calibrated sound intensity meter. It is a sound pressure noise level. The detailed method please refer to the following information:
Installation state: the unit should be placed on the flat floor or be mounted in horizontal direction. Testing method:

2.air outlet from top: the noise level is the average sound pressure level measured from front, back, left, right directions.
measured point:
H ( height to the ground) = (h (unit height) + 1m) /2 and, it is 1m to each side.

b.easy to piping with the indoor and the outdoor unit, and the distance from the box to the indoor unit should not exceed a certain value;
c.do not have a heat or steam source nearby;
d.should be sunless and be dry;
e.should be well ventilated and rainproof;
f.do not have a strict noise restriction, because when working the box may make some noise;

5.4 MP2A, MP3A Installation Requirement
1. Cautions
1.1The place should be strong enough to support this equipment, no vibrantion;
1.2The place where is convenient to install the indoor unit, outdoor unit and the refrigerant pipe, and the length of the pipe is in the permitted range;
1.3No heat source and gas source nearby;
1.4The place has enough space for installation and maintenance;
1.5 Don |
t installation in the place in the state of high temperature and high humidity for a long time; |
1.6 The place with good ventilation, no direct sunshine and rain; |
|
1.7 Don |
t install the unit near the bedroom because of the refrigerant flow noise; |
Please refer to the cautions and warnings in the operation manual about the other safety cautions. 2. Installation Method
2.1 MP2A, MP3A can be installed on the horizontal ceiling or the vertical wall by adjusting the fixing holder. The maintenance plate should be installed on the place easy to maintain and near the place, there should be checking hole with 600mm*600mm (adjust the fixing holder as below figure).
wallvertical
2.2The equipment has been dealt with the EPS heat insulation material, so the drainage pipe needs not any other treatments.
2.3The pipe connected to indoor is led from the branch pipe of the equipment. The gas pipe diameter can realize to match with different diameters by the changing pipe according to the indoor pipe diameter request.
2.4 |
In installation, the equipment gradient should be in the range of 5 , or it may cause electronic |
expansion valve body in the equipment leakage or the other bad control failure. |
|
2.5 |
Bolt, screw cap and gasket to fix the equipment will not be supplied by factory. |
3. Wiring Connection
3.1The wire and refrigerant pipe must be connected to the corresponding place (refer to marks on the equipment and the terminal block as 1,2,3).
3.2Wiring diagram is sticked on the back of cover plate, and the wiring must be performed according to the wiring diagram, or the control will be bad or indoor and the equipment will be damaged.
3.3After wiring, the wires must be fixed with the wire clip firmly, in case that the electric control parts are damaged or occurs person injury.

2. The ceiling concealed unit must connect with the outdoor unit through the MP2A or MP3A; the wall mounted unit must connect with the outdoor unit through the exterior EEV box; while for the cassette unit, because it has the built-in EEV, so it need not anything and it can connect to outdoor directly.

5.7 Attentive matters of safety
Before installing, do read this [Attentive matters of safety] carefully to guarantee the proper installation.
The below attentive matters are divided into [warning] and [note] two parts. When the wrong installation occur, it is very possible death and severe injury and other serious accidents will happen. For those items are listed in [warning] part. But even the items listed in [note] part can also cause serious accidents. Above all, both the two parts are very important contents related to safety, so they must be obeyed.
After installation, do test run to verify everything is normal, after that please explains the use method and maintenance method to the user according to the operation manual. Additionally, give the installation manual together with operation manual to the user and ask them to keep them properly.
Warning
The distributing shop, where you bought the air conditioner, or the specified shops shall do the installation work. If you do the installation work by yourself, the improper installation will cause water leakage, electric shock fire and other accidents.
The installation work shall be in line with what the installation manual specified. If installation is not proper, water leakage, electric shock, fire and other accidents will occur.
Install the air conditioner to a place where can definitely stand its weight. Places not firm enough will cause drop down of unit resulting in body hurt.
The installation work shall be preventive to typhoon and earthquake. If the installation

|
|
work is not met with the requirements, overturn of the unit will occur resulting in accidents.
The wiring work shall be done by a qualified person and referred to the “technical standard of electric equipment”, “indoor wiring regulation” and what the manual specified. Do use special circuit. If the capacity of the circuit is not enough or bad work, electric shock, fire and other accidents will happen.
Using the specified cable to do wiring work and connecting firmly and properly. Fix the connecting part of the terminals to prevent it from the external force. Improper connection and fixing will cause heating and fire etc. accidents.
Wiring shall be kept in correct shape avoiding extrusion. After installation, the electric box cover and the external panel shall not nip the wire. Improper installation will cause heating and fire etc. accidents.
When setting or moving the air conditioner do not let the air and things alike get into the refrigeration system except the specified refrigerant. If air and other things enter,abnormal
high pressure will occur, which easily cause break and body injuries etc.
When installing, do use the accessories or specified parts. If not using the parts specified by our company, water leakage, electric shock, fire and refrigerant leakage will occur.
Do not lead the drainpipe to drain where the sulfur gas may be involved. Otherwise, the poisonous gas will enter into the indoor.
During installation, if refrigerant leakage occurs, do the ventilation work immediately. As soon as the refrigerant gas meets fire, poisonous gas will be produce. If the refrigerant gas enters into room and meet the air blowing heater, heater or stove etc. fire source, the poisonous gas may be produced. After installation, confirm there is no leakage of refrigerant.
Do not install the unit in a place where the combustible gas may be leaked. In any case the combustible gas leaks and accumulated around the unit, fire accident will occur.
Do heat insulation work to the refrigerant gas pipes and liquid pipes to reach the purpose of heat preservation. If the heat insulation measure is not sufficient, water generated by condensing dew will drip leading to wet the floor and indoor articles.
Do not damage the power line or change it arbitrarily to avoid occurrence of fire or electric shock.
Do not extend the power line or using other electric appliance in the same power receptacle to avoid fire or electric shock.
Note
Do grounding work. Do not connect the grounding wire to gas pipe, tap, lighting rod or telephone line. Improper grounding will cause electric shock.
In some places the electric leakage breaker shall be installed. If do not install the breaker, electric shock may occur.
After installation, power on to do electric leakage detecting test.
