Safety Awareness

1.

Procedures: operation shall be made as per controlled procedures to minimize the probability of risks.

2.

Area: area shall be divided and isolated appropriately, and operation in an enclosed space shall be avoided.

Before  the  refrigeration  system  is  started  or  before  hot  working,  ventilation  or  opening  of  the  area  shall  be 

guaranteed.  

3.

Site inspection: the refrigerant shall be checked.

4.

Fire control: the fire extinguisher shall be placed nearby, and fire source or high temperature is not allowed;

the sign of “No smoking” shall be arranged. 

Unpacking Inspection

1.

Indoor unit: nitrogen is sealed during the delivery of indoor units (inside the evaporator), and the red sign at

the  top  of  the  green  plastic  seal  cap  on  the  evaporator  air  pipes  of  the  indoor  unit  shall  be  checked  first  after 

unpacking. In case the sign is raised, the nitrogen sealed still exists. Afterwards, the black plastic seal cap at the 

joint of evaporator liquid pipes of the indoor unit shall be pressed, to check whether nitrogen still exists. In case 

no nitrogen is sprayed out, the indoor unit is subject to leakage, and installation is not allowed.  

2.

Outdoor unit: the leak detection equipment shall be extended into the packing box of the outdoor unit, to

check whether the refrigerant is leaking. If the refrigerant leakage is identified, installation is not allowed, and the 

outdoor unit shall be delivered to the maintenance department.  

Inspection on Installation Environment

1.

The room area checked cannot be less than the area specified on the warning sign of the indoor unit.

2.

Inspection  on  the  surrounding  environment  of  place  of  installation:  the  outdoor  unit  of  flammable

refrigerants air conditioner cannot be installed inside an enclosed room reserved. 

3.

Power  supply,  switches  or  other  high-temperature  articles  such  as  the  fire  source  and  oil  heater  shall  be

avoided below the indoor unit. 

4.

The power supply shall be provided with earthing wire and be reliably earthed.

5.

While  punching  the  wall  with  an  electric  drill,  whether  embedded  water/electricity/gas  pipelines  are

designed at the hole preset by the user shall be verified in advance. It is recommended that the through-wall holes 

reserved shall be used as much as possible.  

Safety Principles of Installation

1.

Favorable ventilation shall be maintained at the place of installation (doors and windows are opened).

2.

Open fire or high-temperature heat source (including welding, smoking and oven) higher than 548  is not

allowed within the scope of flammable refrigerant. 

3.

Anti-static measures shall be taken, such as the wearing of cotton clothes and cotton gloves.

4.

The place of installation shall be convenient for installation or maintenance, and cannot be adjacent to heat

source and flammable and combustible environment. 

5.

In case of refrigerant leakage of the indoor unit during installation, the valve of the outdoor unit shall be

closed immediately, and windows shall be opened, and all the personnel shall be evacuated. After the leakage of 

refrigerant is handled, the indoor environment shall be subject to concentration detection. Further handling is not 

allowed until the safety level is reached.  

6.

In  case  the  product  is  damaged,  it  must  be  delivered  to  the  maintenance  point.  Welding  of  refrigerant

pipelines at the user’s site is not allowed. 

7.

The installation position of air conditioner shall be convenient for installation or maintenance. Barriers shall

be  avoided  around  the  air  inlet/outlet  of  the  indoor/outdoor  unit,  and  the  electrical  appliance,  power  switches, 

sockets, valuables and high-temperature products within the scope of  both sidelines of the indoor unit shall be 

avoided.
