2. Detailed explanation of refrigerant addition steps
1. Preparation
Tool list:
| Tool name | use |
|---|---|
| pressure gauge set | Check system pressure |
| refrigerant tank | Store refrigerant |
| electronic scale | Precisely measure the amount of addition |
| protective gloves | avoid skin contact |
2. Operational procedures
(1)power off: Make sure the device is powered off.
(2)Connect pressure gauge: Connect the high and low pressure pipes to the system valve.
(3)vacuum: Use a vacuum pump to remove air and moisture (recommended for more than 15 minutes).
(4)Add refrigerant: Inject slowly according to the refrigerant type and weight marked on the equipment.
(5)Test run: Start the equipment and observe whether the pressure gauge reading is within the normal range (usually low pressure 0.4-0.6MPa, high pressure 1.5-2.0MPa).
3. Frequently Asked Questions and Precautions
| question | solution |
|---|---|
| Overcharge of refrigerant | Stop immediately and drain excess refrigerant |
| No change in pressure gauge | Check if the valve is fully open or if the system is leaking |
| Wrong refrigerant type | Thoroughly clean the system and refill with the correct model |
4. Safety tips
(1) Refrigerant is a chemical product and needs to be operated in a ventilated environment.
(2) Do not allow open flames to approach. Refrigerants such as R22 may generate toxic gases when exposed to fire.
(3) It is recommended that non-professionals contact after-sales service or certified technicians for operation.
Summarize: Refrigerant addition must be performed strictly in accordance with the specifications. Improper operation may cause equipment damage or personal injury. Although there are many DIY tutorials that have been hotly discussed recently, safety is still the first principle!
