Remove the caps from the 2-way and 3-way valves and from the service port and connect a vacuum pump hose to the service port. Turn the vacuum on until it reaches an absolute vacuum of 10mm Hg. Close the low pressure knob and then turn off the vacuum. Test all of the valves and joints for leaks, then disconnect the vacuum. Replace the service port and caps. To ensure the pipes and cables don't move around or become disconnected, attach them to the exterior wall of your home using the clamps that came with the kit. Follow the directions in the manual to ensure the clamps are spaced adequately. Spray expanding polyurethane foam into the hole you drilled to feed the cable and piping through the wall. Make sure the hole is completely sealed to prevent hot air or insects from getting through. Let the foam dry as per the instructions on the label before turning on your air conditioning. All that's left to do is to start the A/C, which you can do from the indoor unit. It should only take a minute or 2 for cool air to start blowing into your home. Refer to the instruction manual if you have any trouble operating your new air conditioner.
