A leak test must be done after the installation is completed.
It is a must to do the safety inspection before maintaining or repairing an air conditioner
using combustible refrigerant in order to ensure that the fire risk is reduced to minimum.
It is necessary to operate the machine under a controlled procedure in order to ensure
that any risk arising from the combustible gas or vapor during the operation is reduced to
minimum.
Requirements for the total weight of filled refrigerant and the area of a room to be equipped
with an air conditioner
1. Site Safety
2. Operation Safety
Open Flames Prohibited Ventilation Necessary
Open Flames Prohibited
Mind Static Electricity Must Wear Protective Clothing and anti-static gloves Don't use mobile phone
3. Installation Safety
Refrigerant Leak Detector
Appropriate Installation Location
The left picture is the schematic diagram of a refrigerant leak detector.
Please note that:
1. The installation site should be in a well-ventilated condition.
2. The sites for installing and maintaining an air conditioner using Refrigerant R32 should be free from open fire
or welding, smoking, drying oven or any other heat source higher than 548 which easily produces open fire.
3. When installing an air conditioner, it is necessary to take appropriate anti-static measures such as wear anti-
static clothing and/or gloves.
4. It is necessary to choose the site convenient for installation or maintenance wherein the air inlets and outlets of
the indoor and outdoor units should be not surrounded by obstacles or close to any heat source or combustible
and/or explosive environment.
5. If the indoor unit suffers refrigerant leak during the installation, all the personnel should go out till the refrigerant
leaks completely for 15 minutes. If the product is damaged, it is a must to carry such damaged product back to
the maintenance station and it is prohibited to weld the refrigerant pipe or conduct other operations on the user's
site.
