One (1) system per TPT.
The 6-inch aluminum Y assembly used in the contaminated fuel module is crated in a partially assembled condition to
facilitate packaging and shipping. Some assembly is required to place the units in operating condition prior to
installation.
3-23.1
Assembly. Refer to figure 2-39.
a.
Remove coupling clamps (2) connecting flanged adapters (3) to Y fitting (l).
b.
Slide one 6-inch coupling gasket over each Y fitting (1) flange.
c.
Align mating surfaces of adapter (3) and Y fitting (1). Pull coupling gasket over sealing surfaces of both pieces.
Ensure gasket is correctly positioned over full circumference of sealing surfaces. Position coupling clamp (2) over
gasket.
d.
While maintaining alignment of mating parts, lock coupling clamp securely.
e.
Repeat steps j. thru I. for other branch of Y fitting (1).
3-23.2
Installation . Refer to figure 2-65.
CAUTION
INTERNAL CLEANLINESS
Make sure all hoselines, fittings and valves are clean internally. Foreign materials may disrupt
operations and damage equipment.
NOTE
Elbows (13 and 14), 4-inch suction hoses (11), and 4-inch gate valves (12) are overpacked with
the 50,000 gallon tanks.
a.
Connect elbows (13) to outlet ports of 50,000 gallon tanks. Connect 6-inch reducers (4) to elbows.
b.
Connect coupling adapters (3) to 6-inch reducers (4).
c.
Install 6-inch discharge hoses (2) between coupling adapters (3) and gate valves of Y assembly (1).
d.
Connect 6-inch discharge hose (2) between Y assembly (1) and switching manifold gate valve.
e.
Connect elbows (14) to inlet ports of 50,000 gallon tanks.
f.
