Pipe snugly engaged within the Header, the opening of the glass tube inside the Manifold receptacle and
the bottom of the tube, protected by the Rubber Cap, will reside in the low spot between each set of tines on
the Bottom Track, where it will be held in place by the Bottom Track Clip.
Each tube receptacle in the Manifold needs to line up with the corresponding “cradle” on the Bottom Track,
otherwise the tubes will not engage properly with the Header and/or Bottom Track Clips will not fit snugly.
Make sure to line the center point of the receptacle in the Manifold with the center point in the “cradle” on
the Bottom Track and that the Manifold and Bottom Track are square with the standard frame channels.
Try to locate standard frame channels under the 2nd or 3rd tube from each end. By locating the standard
frame channels directly under the evacuated tubes, the stainless steel frame will be hidden, improving the
aesthetics of the installation. For collectors with three standard frame channels (30 tubes), the middle
standard frame channels should be positioned roughly centrally, again ideally behind a tube (it is more
important for this piece to be over a roof framing member, than that it is out of sight).
The horizontal brace (Part #: FR-HBRACE) provided with the standard frame kit gives an indication of the
standard location of the standard frame channels. Holes are spaced at 8” centers to match 16” or 24”
centered rafters. Additional holes may be drilled in the horizontal brace to meet different standard frame
channel locations, however the component is NOT structural and is simply to help with alignment, so it can
be removed if not convenient. If NOT using the horizontal brace, a string can be used to check the
diagonals corners of the frame to determine if it is square; if the dimension from one set of opposite corners
(top-left to bottom-right or top-right to bottom left) is different than the other set, then the frame is out of
square and should be corrected before proceeding.
If installing a drain-back system, the frame must be rotated slightly to achieve a 1/4” per foot slope toward
whichever header port will be the collector outlet (hot), to promote complete drainage.
5.2.6. Manifold and Bottom Track Attachment
a) Once the standard frame channels are secured in place, the manifold and bottom track may be attached,
taking care to ensure they are correctly aligned (see 5.2.2). The manifold and bottom track will lock into the
frame, secured from above and below with the attachment plates that are already in place. See also 5.1.4.
5.3. Mounting on Insufficient Pitched Roof (Angled Frame)
If the roof pitch is insufficient, an adjustable angle roof frame kit can be used to increase the angle by 27° to 57°.
Adjustable frame kits combine with the standard frame components to form a complete frame assembly.
Refer to Appendix 2 for frame assembly diagram.
5.3.1. Frame Options
Three frame options are available:
a) U-Feet are the new standard Apricus mounting solution. DO NOT forget to order them. They are
compatible with most commercially available flashings, such as those outlined in sections 5.1.7, 5.1.8, 5.1.9.
b) Roof Tracks are the ideal choice if attaching to Unistrut. They consist of a C-channel similar to the
standard frame front track. Rubber pads should be used between the roof track and the Unistrut to prevent
galvanic reaction of the dissimilar metals.
c) Round Feet are suitable for attachment to concrete ballast on a flat roof. Round feet allow some front
and back movement of the rear legs, thus allowing a slight adjustment of the install angle.
In cases where any option is viable, U-Feet, together with a suitable flashing mount, provide the most cost
effective and flexible solution.
5.3.2. Rear X Brace Adjustment
The rear X brace components have a series of holes to allow adjustment of the location of the legs. If
further adjustment is needed, additional ∅0.35” (∅9 mm) holes may be drilled to suit. As the grade of
stainless steel used is quite hard, good quality drill bits are needed. Take care when using power tools.
Never do any drilling of the frame while on the roof.
