Will you really turn it on? Learn to perform 18 necessary checks before and after the start of the air source heat pump to help your unit have a longer life

Air source heat pump heating is becoming more and more popular among users. However, in order to make the air source heat pump heating system run more stable in winter and have a longer system life, it is best to do a "full body inspection" of the entire system before use. Specifically check the following details.

1) Confirm the installation of the outdoor unit of the air source heat pump:

1. Whether the appearance of the unit and the pipeline are damaged

2. Whether the reserved maintenance space around the unit meets the distance requirements of the unit

3. Whether the air flow in the direction of the air inlet and outlet of the unit is smooth

4. Whether the installation foundation, shock absorption measures and installation of the unit are firm

2) Confirm the external water pipe connection of the air source heat pump:

1. Check whether the pipe diameter of the water system meets the requirements

2. Check the water system pressure, make up water and empty if necessary

3. Check whether the water inlet and outlet of the water system unit have shock absorption soft connections

4. Check whether the thermometer and pressure gauge are working properly

5. Start the water pump and observe the running status of the water pump

6. Check the state of the water flow switch and whether the contact is normal

7. The cleanliness of the water quality of the water system, if necessary, clean the water filter and replace with new water

8. Check the pipe insulation to ensure that it is intact and there is no leakage in the water system

3) Confirm the electrical installation of the air source heat pump unit:

1. Check whether the capacity of the air switch equipped with the unit meets the requirements

2. Check whether the power supply voltage of the unit is normal, and the unbalanced voltage of the three-phase power supply does not exceed 2%

3. Check whether the power line diameter and communication line specifications meet the requirements of the unit

4. Check whether the wiring is correct and whether the wiring terminal has been pressed tightly and there is no virtual connection

5. Whether the wiring of communication line and power line meets the requirements of anti-interference

6. Check whether the unit has been warmed up for 12 hours
