- If the vacuum doesn’t maintain, there could also be a leak within the system.
Attaining a Vacuum Maintain
To realize a vacuum maintain, comply with these steps:
- As soon as the vacuum has been drawn, shut the valve on the vacuum pump.
- Flip off the vacuum pump.
- Observe the vacuum gauge for not less than quarter-hour.
- If the vacuum holds, the system is able to be charged with refrigerant.
Troubleshooting Vacuum Maintain Points
If the vacuum doesn’t maintain, there could also be a leak within the system.
To troubleshoot vacuum maintain points, comply with these steps:
- Test all the connections to make sure that they’re tight.
- Examine the hoses for any leaks.
- Use a leak detector to verify for any leaks within the system.
- If a leak is discovered, restore the leak and re-evacuate the system.
Word: In case you are unable to seek out and restore the leak, you must contact a professional HVAC technician.
Charging the System
To cost the system with refrigerant, comply with these steps:
- Join the refrigerant charging hose to the high-pressure service port on the outside unit.
- Open the valve on the refrigerant tank.
- Slowly open the valve on the refrigerant charging hose.
- Monitor the strain gauge to make sure that the system is being charged correctly.
- As soon as the system has been charged to the specified strain, shut the valve on the refrigerant charging hose.
- Shut the valve on the refrigerant tank.
Testing the System
To check the system, comply with these steps:
- Activate the mini-split system.
- Set the thermostat to the specified temperature.
- Monitor the system to make sure that it’s working correctly.
If the system is working correctly, the set up is full.
Commissioning the Mini Break up System
