How To Connect A Vacuum Pump To A Split System

To use a vacuum pump on an air conditioner first turn the pump on and open the side gauge valve which will allow the vacuum to start pulling air out of your system.

How to connect a vacuum pump to a split system. Connect the vacuum pump via the manifold gauge to the port of the compressor and open the low pressure gauge valve. Alternatively a micron gauge can be used in place of hvac gauges and do the same thing. Connect your vacuum hoses or copper lines to valve core removers and vacuum pump. The deeper and more complete the vacuum the more contaminants trapped within the system its components and even the compressor oil are removed.

Turning the vacuum pump off before shutting the manifold valves will cause the the heat pump to suck the oil out of the vacuum pump contaminating the system. The yellow hose goes to the vacuum pump. Once the valve is open let your vacuum run at full speed for 15 to 30 minutes to pull out as much air as it can. Mini split adapter 5 16 to 1 4 coupler.

Connect your vacuum gauge as far from the vacuum pump as possible preferably on the system. A vacuum pump simply evacuates all the air from the system placing it in a vacuum.

A vacuum pull for 30 minutes is needed to evacuate all the water vapor in the copper lines.

This creates a vacuum state. Hvac gauges and a vacuum pump are needed to set a mini split into a vacuum. This creates a vacuum state. Run the vacuum pump until the electronic vacuum gauge is registering about 500 microns.

Deep vacuum method will require you to pull vacuum down to 500 microns or less ideally. Shut the valves on the manifold off and then turn off the vacuum pump.
