10.1 Separating/Attaching Trap and Connector Bodies
1. Loosen and remove the connector bolts, remove the entire trap unit from the connector body
and take it to a repair area where it can be supported in a vise during disassembly.
2. A When reinstalling the original trap:
a. Using a small screwdriver, remove the old gaskets from their housings in the trap body,
then clean the housings.
b. New connector gaskets must be installed.
c. To facilitate assembly and prevent loosening of the gaskets, apply a small amount of
suitable adhesive at 120˚ intervals around the outer edge of the gaskets.
d. Holding the trap body so that the gasket housings are horizontal, place the gaskets into
the housings.
2. B When installing a replacement trap:
a. Be sure to remove all protective seals, making sure the connector gaskets are still in place
after having removed their seal.
b. Before installation, scrape the mounting surface of the connector body clean using a soft
tool.
3. Align the bottom edge of the trap body with that of the connector body (see Fig. A), making
sure the gasket housings on the trap body align with the corresponding recesses in the
connector body. Maintaining the proper alignment, close the tops together until the two
faces are flush, making sure that connector gaskets remain in position.
4. Insert the connector bolts and finger-tighten, keeping
trap and connector bodies flush. Tighten the connector
bolts to the proper torque.
