 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.
