1) Install first Post to the proper height, with theopening facing north, and plumb to within +/- 1degree. Make sure next Posts are installed atspecified distances from marked locations(East-West +/- 1", North-South +/-1")The racking system allows for +/-2" but this will makemore adjustment of purlins necessary and slow downinstallation.

• Make sure tops of Posts are leveled to be at aconsistent height or slope depending on thetopography of the land (with a tolerance of optimally+/- 1 inch).

• Note that embedment depth will vary to handle rollingground variations. Gamechange provides piles withadditional length enabling an adjustment rangetypically of 4" to 6". Be careful to always meetminimum embedment depth and ground clearancerequirement.

Proper height

2) Place NS Beams on top of Posts with longerpart to the south. Align 3/4" mounting hole with3/4" slot on top of Post.

3) Attach NS Beam using 2 sets of 3/4" bolts,washer (under bolt head and serrated flangenut) and serrated flange nuts. Do this on bothsides of Post. Do not fully tighten.

North

• Make sure Post are plumb, optimally +/- 1 deg so long as:Not more than +/- 1 1/2 inches on east to west direction at top of post (from the proper postlocation marked on ground).The racking system allows for +/- 2 1/2 inches but this willmake more adjustment of purlins necessary and slow down installation.Not more than +/- 1 inch north to south direction at top of post (from the proper postlocation marked on ground)

• Make sure defined distance between foundations is measured from center of post tocenter of next post along the ground (not from plan view). Otherwise foundation locationswill creep if there is rolling terrain. since plan view does not factor in dimensionsdifferences caused by terrain. This could make purlin attachment more difficult.

GC Max-Span System

• Use only GameChange parts. Use of other parts to complete the installation assubstitutes may void the warranty.

• Make sure the site ground can support the loading resulting from the GC Max-SpanPost System and provided PV modules.

• Follow all safety instructions that are required by relevant local, regional and nationalorganizations and procedures as outlined in this Install manual, both for mechanicaland electrical aspects of the solar PV array installation.

• When encountering undocumented or unexpected obstacles requiring a work around.Work arounds should be noted on working drawings and notified to supervisor forevaluation. Work should then be completed in a manner that ensures that theremainder of the array is not affected.

• GC Max-Span Post System is to be installed in a clear area free of shading with asuggested 10 ft border surrounding array.

• For continuous racking without breaks, ground must be at an east-west slope nogreater than 5% to minimized east-west shading.

• Reference Install Manual for installation. Not following install manual may result invoiding warranty.

• Make sure to place the array in areas where there is no shading.• Install the array facing as close as possible south.

Tool Required

• Deep Sockets and driver for 1/4", 3/8", and 3/4" hex bolts and nuts.• Wrench for 1/4", 3/8", and 3/4" hex bolts and nuts• Suggested driver torque (with lubrication):

1/4" hardware = 6 ft-lbs 3/8" hardware = 20 ft-lbs3/4" hardware = 140 ft-lbs

• String Line• 30 ft Tape Measure• Anti-Seize lubricant such as LocTite for bolts used to mount panels, unless pre-dipped• Threadlocking fluid such as Threadlocker for bolts or nuts used to mount panels,

unless pre-applied

Preventative Maintenance

• After Installation, installer must annually monitor for any surface rust that may occurover time. Identify any rust areas, wire brush area to remove rust, and coat with 70%zinc rich paint, or equivalent field life paint . This step is not required if rust is limited toedges which were cut during fabrication.

• If panel mounting clips are used to install modules, clips must be checked annuallyand after storms with severe winds to make sure their installation and torque settingsremain correct.

• Annual inspection must be done for mechanical movement due to any reasonincluding thermal expansion and contraction. Any mechanical movement must berectified.

• Torque settings must be checked for all hardware.• All Clips must be checked to make sure there is no gap between side of Clip and

module.• Proper preventative maintenance must be conducted or warranty may be voided.

9) Attach Bend Straps, Roll Ties, Roll Straps, and Purlin Angles as required. Use 3/8"bolts and serrated flange nuts to attach. Make sure all hardware is tightened to propertorque settings.This is a general guideline only, please refer to install manual whichmust be followed for proper installation or warranty may be voided.The Purlin-to-Beam Supports and Purlin to Purlin must be taut, this is very important

8) For continuous configurations, Purlinends shall be connected together using3/8"bolts (serrated head or not), washersand serrated flange nuts. Torque tospecifications. When floating Purlinconnect to table Purlins, there will be anominal drop of 1/8 to 1/4 inch from onePurlin to the next, which will result in asmall corresponding drop from one panelto the next. This is normal, and is not ashading or functional issue.

7) Attach EW Purlins to NS Beamsusing 3/8-inch bolts and serratedflange nuts. EW Purlins should beattached with 2 bolts. Place aBeam Washer Double on the underside of the Beam. Place a PurlinWasher under the hex bolt closerto the Purlin wall while the hex boltfurther from the Purlin wall onlyreceives a flange nut. Tightenhardware to specification.Alternatively bolts may come upand flange nuts be above Purlins.

If Purlin Channel Washers areprovided as an alternate to PurlinWashers, be sure that the bentflange is bearing against the Purlinwall prior to torquing the hardware.It is essential to always use PurlinChannel Washers with 16 GaugePurlins

12) The modules, EW Purlins and NS Beams are all bonded together, left to right, sothat each row form one single structure. GameChange recommends up to 16 stringsmay be grounded on one grounding lug which should be attached at the holeprovided next to the marking “GROUND”. Install Cooper, Burndy, or Eaton. ULapproved grounding lug with 1/4-inch bolts as in accordance with NEC Article 690 tothe end of the last EW Purlin which has panels attached to it which are to be bonded,using 8 gauge copper wire. Repeat for each 16 strings.

The entire system needs to be grounded from a single point to an appropriategrounding source.**Please confirm with an electrician, as this is their responsibility**

10) Attach first panel to EW Purlin through mounting holes nearest to NS Beam. Place astar washer at one mounting location per panel. Insert hex bolt through the Purlin, themounting hole on the back of the panel, and then through the star washer. Attach witha serrated flange nuts on the bolt end inside the panel. Check again to make sure starwasher is still in place. Torque to specifications. Repeat for all panels.

11) For bottom mount attachment of panels GameChange typically provides slotted panelmounting holes to enable panel adjustment in case purlins are not perfectly aligneddue to rolling or otherwise uneven ground situations. It is the customer's responsibilityto make sure to follow panel spacing guidelines if any are given by panel vendor intheir specification sheet or elsewhere, otherwise panel warranty could be voided. In allcases make sure panel spacing is the greater of 1/8 inch or the minimum called out bythe panel vendor. This will allow for thermal expansion of panels. GameChangesystems typically enable 1/2 inch panel spacing if aligned properly. Spacing betweenpanels can be set by placing a temporary spacer such as bolt shaft or plywood ofsame thickness as required for panel spacing between panels while they are beinginstalled. This spacer should be removed after panel installation is complete.
