Mount Assembly Instructions

UTRF-168 Schedule 40 – 8” nominal
• Heavier steel pipe (sch 80 or sch 120) can be used as long as outer diameter is 6.625”
or 8.625” respectively.
• Using the chart provided below, find the MINIMUM acceptable pole height above your
finished grade. The suggested pole heights will provide approximately 3' of ground
clearance with the largest module arrays installed. It is strongly recommended that the
pole height meet our minimum specifications.
• The MINIMUM recommended hole depth is 1/3 the total length of the pole – 1/3 in the
ground, 2/3 above the ground.
For example: 10' above grade, 5' below grade – 15' total length.
• Center pipe in hole, use a level or plumb line to insure pipe is vertical.
• Fill the hole with concrete (3000 psi minimum strength), and recheck verticality.
• The pipe may be filled with concrete for added strength (only to approximate ground
level)
• Allow concrete and pipe to set for a MINIMUM of 36 hours before installing Track

Attaching Gimbal to Pole
• Place Gimbal on top of pole.
• Orient Gimbal so that 3/4” x 2” bolts are facing
true south (adjust for magnetic declination)
• Tighten bolts to 75-100 ft-lbs torque in turns
to insure both are tight.
