Also pay attention to where the access hole to get to the unit is at and that you have enough clearance per code to get to the unit. • Build your platform large enough so that the threaded rods can miss your service and still have room to support the platform. We recommend building wood platforms 9” larger than your threaded rod spacing. This allows room for a 2x4 block on each side of the platform to be install and stop the uni-strut from ever sliding out from under platform. DO NOT BUILD YOUR PLATFORM WITHOUT FIRST DETERMININNG WHERE YOUR THREADED RODS WILL BE! • Confirm that the structure you are hanging from can support the weight of not only the unit but the platform, all hardware, etc. It is good practice to overbuild for people leaning or stepping on the platform or design changes but do not go too far overboard on springs because if springs are too oversized they will not dampen vibration as much. • USE PILOT BIT WHEN SETTING LAGS!!! Lag sizes listed at bottom of this page. • Build drain pan larger than unit, 3” recommended (1” minimum if clearance is tight). • Install “break joint” at any equipment that may vibrate to stop transfer of vibration into house. • Use assembly line process and cut all threaded rod, uni-strut etc at one time when possible but be careful to triple check everything before you cut all your material.
