Follow the following steps: 1. Simply unscrew it counterclockwise. 2. Tap the bottom of the antifreeze reservoir to remove some of the air from the antifreeze reservoir. 3. Use a punch to pry up the antifreeze cap to remove some of the air and make it easier to unscrew the cap. 4. Pour the lid of the antifreeze bucket with hot water, only the lid. Leave a space between the cup lid and the cup body. 5. Poke a small hole in the cup (or lid) to "leak" it and achieve a balance between internal and external air pressure.
What should you pay attention to when using a geothermal heat pump in winter?
1. First drain the water from the engine cooling system and flush the engine cooling system with water;
2. Add the required amount of antifreeze according to the dilution rate and allow it to reachnormal temperature after running for a few minutes
3. for dilution first, or clean tap water, well water.

What problems will occur if the geothermal heat pump condenser freezes?
1. Add antifreeze in time
Avoid all possibilities when using geothermal heat pump. . Only in the event of a breakdown can the stable and normal operation of the geothermal heat pump be ensured throughout the winter. So it is very important to do a good job of antifreezing the unit. Most geothermal heat pumps automatically activate the antifreeze function when the temperature is low in winter. In this case, the geothermal heat pump must be turned on automatically when the geothermal heat pump is turned on, so the prerequisite is. to ensure that the geothermal heat pump is turned on.
If the water from the geothermal heat pump is not drained properly during usen winter, antifreeze must be added, otherwise it will damage the geothermal heat pump unit.
2. Pay special attention to damage to the air conditioning system caused by power outages, water shortages or improper use of geothermal heat pumps in winter to avoid affecting normal use.
Causing damage to the air conditioning system of the geothermal heat pump and affecting the normal use of the unit. When using geothermal heat pump air conditioners in winter, you should pay attention to the following issues:
1. The refrigeration cycle pipe should be checked before use, then the heating cycle pipe valve should be opened.
2. Check unit wiring. To avoid problems such as phase loss and phase reversal, you should also check whether the external ground wire is reliably connected. If any abnormalities are found, they should be replaced in time.
3. Check the condenser. The water in the condenser should flow normally, and the outlet pressure difference of the condenser and evaporator should be observed at the same time. When cleaning is necessary, it should be cleaned in time.
4. Cleanly drain the water from the appliance. If it is not drained cleanly, antifreeze should be added, otherwise long-term operation will cause certain damage to the geothermal heat pump air conditioning unit.
5. Check the inlet and outlet of the indoor unit regularly to prevent the air outlet from being blocked. After a while, you can ask professional maintenance personnel to clean the indoor unit filter.
