Rheem RRCUTD36K Installation Instructions

Installation Instructions for Roof Mount Tie-Down Kit
New Platform Rheem & Ruud Outdoor Units
1) Center unit on roof mounted I-beams in the desired orientation. The I-beams must be at least
20" apart on center.
2) Refer to installation drawing on the reverse side of this sheet for steps 3 – 9.
3) Place the (2) of the 3" x 3" aluminum angles included in kit across the I-beams and against the
unit base on opposite sides of the unit as shown in details 1, 2, and 5. Push the 3" x 3" angles
against the side of the unit base pan and orient them perpendicular or square with the I-beams.
4) Note: Clamps are recommended for holding the angle frame in place while drilling through the
angles and I-beams.
5) Drill a 3/8" diameter hole through each of 3" x 3" aluminum angle where they rest on the I-
beams (total of 4 holes) and then through the top flange of the I-beam as shown in detail 3.
6) Insert the four (4) 3/8" bolts included with the kit through the holes in the angle and I-beam that
were drilled in step 5 above. Slide a 1" x 3" reinforcement plates included in the kit over each of
the 3/8" bolts on the underside of the I-beam flange and install the washers and nuts as shown
in detail 6. Tighten the nuts using a back-up wrench on the bolt head.
7) Attach each of the four (4) steel "L" brackets included in kit to the sides of the louver panels
with seven (7) #10 x ¾" self-drilling screws included with the kit per details 4 and 5. Be sure the
bottom of "L" brackets are resting on the angles before attaching the brackets to the louver
panels with screws. Please note the brackets are attached to the posts, not the louver panels, to
maintain the ability to easily remove the louver panels when servicing the unit.
8) Using the hole in the bottom of each "L" bracket as a guide, drill a 1/4" diameter hole through
the aluminum angle for the ¼" bolts that will secure the four (4) brackets to the 2" x 1" angles.
9) Insert the ¼" bolts included with the kit through the hole in each bracket and angle, placing the
washers under the head of the bolt and between the nut and angle as shown in detail 4.
Tighten the nuts using a back-up wrench on the bolt head.
