Adjust the Carrier Height (cont.)
To adjust the carrier to the desired height, loosen the nuts
securing the legs to the carrier.
NOTE: As the carrier is lowered, make sure the elbow and gasket
(if present) align with the floor drain pipe.
Adjust the carrier until the desired height is reached. Securely
tighten the nuts using a wrench to secure the legs in place.
NOTE: If a cast iron elbow is required, make the connections
following all applicable codes.
