Step 1
Choose an appropriate location for the concrete pad . Ensure that the stamp pad place the air - conditioning unit close enough to the associated pipe and electric service connections . confer with the technician establish the unit if you are in question about where to teem the concrete tablet .
Step 2
Measure the tune - conditioning unit or consult the whole manual to find out the proper sizing for the concrete pad . Dig a level , flat - bottomed gob 6 - inch thick and 3 - inches longer and full than the pad sizing . Fill the cakehole about midway with gravel or crush stone . Use a manus tamper to exhaustively compact the crushed rock base .
Step 3
Step 4
Use deck screws and 2 - inch - by-6 - inch timber to build up a form for the launch area . check that the interior dimensions of the form match the sizing you determine for the ruined launchpad . come out the 2 - inch - by-6 - column inch form on top of thecompacted gravel . The top of the class should be 2 to 3 inches above the point of the surrounding terrain , or to a altitude otherwise destine by the aura - conditioning building block manual or instal technician .
Step 5
Drive a wooden stake into the ground at each outside recess of the form . Level the form in all directions , then sequester it to the stakes with deck prison guard . thin the wager off even with the top of the conformation . reward the pad with rebar or brand meshing . utilize Rock to hold up the reinforcement 2 to 3 inches above the crushed rock floor of the bod

Step 7
set a garden cart in a compressed , substantial orbit . Empty a bagful of concrete mix into the wheelbarrow . Add urine per the instructions on the base and flux the concrete with a shovel , until you achieve a consistency standardised to that of chunky peanut butter .
Step 8
Pour the concrete into the prepared contour . Immediately mingle another garden cart full of concrete , repeating as many times as necessary to meet the shape . utilize a shovel hold or hold fast to verify the concrete settle around the steel reinforcement as well as into the corners of the phase .
Step 9
engage a scrap piece of timber as a screed . The lumber should reach across the breadth of the form and rest on the sides . Move the screed back and forth as you run it along the sides of the shape to scrape the supernumerary concrete off and level the top . Use a concrete swim bladder if desired for a smoother refinement .
Step 10
Step 11
Cover the concrete with plastic sheeting weighted down at the corners with rocks . Allow the concrete to heal for 24 hours before removing the shape , and seven days before set up the melodic phrase - conditioning unit .
