7.) Install the ABS nipple inside the compression seal. Do not apply sealant or
lubricant to the compression gasket. Position the nipple so the front horn extends
5/16"(8) beyond the finished wall. If necessary the nipple can be shortened by cutting
from the backside (plain end). A styrofoam sleeve is provided to maintain an open
area around the nipple for compression bolt access.
Note: For wide chase installations the carrier nipple may be extended up to
4"(102) (option M1). If a longer nipple is not available, Sch. 40 PVC or ABS
pipe may be substituted. Beyond 4"(102) an auxiliary support (option CA-
100-EXT) is required to support the nipple and rods at the finished wall.
Extended 5/8"(16) all thread rods are furnished by the installing contractor.
8.) Tighten the four compression seal bolts to a torque of 30-50 in. lbs. to secure the
nipple. If a torque wrench is not available, the bolts can be tightened with a standard
socket or open end wrench.
Note: The compression seal will engage and positively seal the nipple with a
minimum amount of force. Do not overtighten the compression bolts.
9.) Adjust the carrier mounting studs to extend approx. 2 1/4"(57) beyond the
finished wall. Adjust the back-up nuts flush with the finished wall, with the back-up
washers outside the wall. When properly positioned, the back-up washers create a
1/16"(2) gap between the back of the bowl and the face of the finished wall.

10.) Following the system pressure test and prior to setting the bowl, knock out the
nipple test cap with a hammer. Make sure any sharp edges or burrs inside the nipple
resulting from the knockout are removed so the waterway is unobstructed.
11.) Remove the adhesive backing from both sides of the bowl gasket. Adhere the
gasket to the back of the bowl, centered around the bowl outlet. Install the bowl onto
the carrier, making sure the bowl gasket is properly seated against the nipple.
Note: Prior to setting the bowl, double check the depth of the nipple to
confirm it extends 5/16"(8) outside the finished wall. The nipple must be
properly positioned for the bowl gasket to create a positive seal.
12.) Install the four chrome cap nuts and plastic washers to secure the bowl.
Note: It is common industry practice for three cap nuts to be fully tightened,
and the fourth left hand tight. This reduces potential stress that can cause the
bowl to crack under heavy loading.
