NOTE: Steps 19-32 apply to pump A only. See FIG. 4.
19. Screw the pump into the bearing housing (M) until
the top threads are level with the bearing face (N).
Rotate the pump to align the pump outlet fitting to
outlet tube.
20. The wet-cup has four 1/8 npt ports. Two will be
inaccessible when the pump is installed. Note or
mark these ports. Remove the pump. Apply thread
sealant and install the plugs in the two ports.
Torque the plugs to 10-15 ft-lb (14-20 N•m). Do
not overtighten.
21. Ensure that the star-shaped locknut (G) is screwed
on the pump with the flat side up. Carefully twist
and extend the rod (1) 2 in. (51 mm) above the
wet-cup assembly.
22. Start threading the pump into the bearing housing
(M). Place a finger guard (P) over the rod when it is
accessible through the window of the bearing
housing. When the pin holes align, insert the pin.
Pull the retaining spring down.
NOTE: A finger guard is not used on Model E-30.
23. Seat a finger guard (P) on the wet-cup (19).
Continue threading the pump into the bearing
housing (M) until the top threads are +/- 1/16 in. (2
mm) of the bearing face (N).
24. Apply thread sealant and screw the barbed fitting
into the motor side of the wet-cup. Torque to 10-15
ft-lb (14-20 N•m). Do not overtighten.
25. Apply thread sealant and screw the elbow (U) into
the remaining wet-cup port. Torque to 10-15 ft-lb
(14-20 N•m). Do not overtighten.
26. Apply thread sealant and screw the barbed fitting
into the elbow (U). Torque to 10-15 ft-lb (14-20
N•m). Do not overtighten.
27. Connect component A outlet tube loosely at the
pump and at the heater. Line up the tube, then
tighten the fittings securely.
28. Tighten the star-shaped locknut (G) by hitting firmly
with a non-sparking hammer.
29. Apply thread sealant and screw the barbed fitting
into the elbow (U). Torque to 10-15 ft-lb (14-20
N•m). Do not overtighten.
30. Apply a thin film of TSL to the barbed fittings. Using
two hands, support the tubes (T) while pushing
straight onto the barbed fittings. Do not let tubes
kink or buckle. Secure each tube with a wire tie
between two barbs.
31. Reconnect the fluid inlet (C) and outlet (D).
32. Purge air and prime the system. See your Reactor
operation manual.
