The Stand-Off brackets are mounted on the corners of the unit and support a perimeter cable approximately 2 feet above and 2 feet out from the outside edge of the unit. Two additional cables are installed diagonally from the end of each standoff support arm (corner to corner) to support the standoff arms and to provide support to the net in the middle of the unit, this insures that the net will not sag down onto the equipment.
On smaller units a cable tension system holds the standoff brackets securely in place allowing installation without penetration of the HVAC unit with screws. Adding two sheet metal screws per corner adds strength. Larger units with spans greater than 10 feet should have sheetmetal screws used to fasten the standoff to the unit. |

The protective net is net ringed to the supporting perimeter cable and down the corner seams. The weighted line is also net ringed securely to the bottom of the net to insure a clean and tight installation.
A zipper can be installed in the net to allow access to the interior of the protection system. In the second example described here a 6' zipper is installed that allows easy access for maintenance.
Where there is a through-the-net-penetration required; cut an access hole in the net and then cut the installation and relief access straight down to the weighted line. Install the appropriate length zipper to close the installation cut. Add that zipper in the options section of the materials calculator. |

Installation Time
The smaller unit (top

took 2 installers 3 hours to complete. The larger unit (bottom picture: 8'
wide x 25' long x 8' high ) took 2 installers 4 hours to complete. |
