ASSEMBLY INSTRUCTIONS FOR PIPE CLAMP HARDWARE
INSTALLATION INSTRUCTION FOR FLANGE MOUNTING HOLE TYPE AIR INLET STRAINER
1.
Obtain appropriate expansion anchors and screws for the type of wall construction strainer will be attached to.
Note that the mounting holes in the strainer are 5/16 [8] diameter.
2.
Locate the strainer on the wall, over the pipe as follows:
2a. Determine the O.D. of the strainer, which will be either:
8 [203] for 3 [76] and 4 [102] pipe
12 [305] for 5 [127] and 6 [152] pipe
15 [381] for 8 [203] and 10 [254] pipe
2b. Determine the I.D. of the pipe, which will be either:
3 [76], 4 [102], 5 [127], 6 [152], 8 [203], or 10 [254]
2c. Subtract the pipe I.D. from the strainer O.D.
Example: 12 [305] strainer O.D. - 5 [127] = 7 [178]
2d. Then divide the difference by 2 [51]
Example: 7 [178] ÷ 2 [51] = 3 1/2 [89]
2d. Measure from the inside wall of the pipe and place a mark on the wall at 3 1/2 [89]. Do this in 4 places
approximately 90° apart from one another.
3.
Measure from one of the marks across to the other and you should have the strainer O.D. dimension.
4.
Position the strainer within the 4 marks which should line up with the edge of the strainer O.D.
5.
Hold the strainer in position and mark the flange mounting hole locations (2 places).
6.
Remove the strainer, drill holes and install expansion anchors (by others), following the anchor manufacturers
instruction for hole diameter, depth and installation.
7.
Reposition strainer, align mounting holes with expansion anchors and attach to wall with screws (by others).
