Numbers and letters in parentheses refer to the figures and the parts list and drawing on page 9.
1. If pumps are not parked, press . Trigger gun
until pumps stop. After fluid pressure drops below
700 psi (4.9 MPa, 49 bar), motor will run until pumps
are at bottom of strokes, then shut off. Pump rod
pins will be showing.
2. Turn main power OFF . Disconnect power
supply.
WAR NING
Pump rod and connecting rod move during operation.
Moving parts can cause serious injury such as pinching or amputation. Keep hands and fingers away from
connecting rod during operation. Read warnings in
Reactor operation manual.
4. Turn both PRESSURE RELIEF/SPRAY valves (SA,
SB) to PRESSURE RELIEF. Route fluid to waste
containers or supply tanks. Ensure gauges drop to
0. Refer to Reactor operation manual.

1. Place pump in vise with soft jaws. Remove brass
packing nut assembly.

2. Install new wet-cup assembly (10). Screw it all the
way down, so external o-ring (R) seats on top of
pump housing. Wrap base of wet-cup with a rag and
tighten securely with channel locks.
10
4. Wet-cup (10) has four 1/8 npt ports. Two will be
obstructed by bearing housing (H) when pump is
installed. Note or mark these ports. Remove pump.
Apply thread sealant and install plugs (3) in the two
obstructed ports. Torque plugs to 10-15 ft-lb (14-20
N•m). Do not overtighten.

5. Ensure star-shaped locknut (G) is screwed on pump
with flat side up. Carefully twist and extend the rod
(R) 2 in. (51 mm) above the wet-cup assembly (10).
6. Start threading pump (A) into bearing housing (H).
Place finger guard (9) over rod when it is accessible
through window of bearing housing (H). When pin
holes align, insert pin. Pull retaining wire clip down.

8. Apply thread sealant and screw barbed fitting (2)
into motor side of wet-cup (10). Torque to 10-15 ft-lb
(14-20 N•m). Do not overtighten.
9. Apply thread sealant and screw elbow (8) into
remaining wet-cup port. Torque to 10-15 ft-lb (14-20
N•m). Do not overtighten.
10. Apply thread sealant and screw barbed fitting (2)
into elbow (8). Torque to 10-15 ft-lb (14-20 N•m). Do
not overtighten.
11. Connect component A outlet tube (D) loosely at
pump and at heater. Line up tube, then tighten fittings securely.
12. Tighten star-shaped locknut (G) by hitting firmly with
a non-sparking hammer.
13. Position holder (4) on Reactor frame upright and
secure with two spring clips (5).
14. Fill reservoir (1) 3/4 full with TSL (6). Place in holder
(4).
15. Apply thin film of TSL to barbed fittings (2). Using
two hands, support tubing (1a) while pushing it
straight onto barbed fittings (2). Do not let tubing
kink or buckle. Secure each tube with a wire tie (7)
between two barbs.
16. Connect swivel elbow (C) to pump fluid inlet.
17. Purge Air and Prime Flush Kit, page 7.

7. When system is fully loaded, check that reservoir is
3/4 full of TSL. Be sure all air is purged from pumps,
lines, and heaters through PRESSURE
RELIEF/SPRAY valves (SA, SB). Trapped air can
cause mix problems at gun.
8. Return Reactor to service.

Maintenance
Maintenance
Changing the TSL
Part No. 206995 Throat Seal Liquid (TSL) carries isocyanate from the pump rod into the reservoir. After some
time the TSL will thicken and darken, and must be
replaced. Thick, dirty TSL will not pump through the
lines and will harden in the pump wet-cup.
How long TSL lasts depends on which chemicals are
used, how much is used, what pressure, and condition
of the pump seal and rod. Check the condition of the
TSL every week, minimum, and change when needed.
To change TSL:
1. Turn main power OFF . Disconnect power
supply.
2. Relieve pressure, see Reactor operation manual.
3. Remove reservoir cap. Empty reservoir (1). Clean
any residue.
5. Fill reservoir 3/4 full with TSL (6).
6. Run pump. Each time pump A rod reaches bottom of
stroke, check that some TSL is pumped from reservoir (1), through wet-cup (10), and back to reservoir.
