Installation
NOTE: Apply pipe sealant (19) to all non-swiveling

NOTE: On pumps with a 3/4 npt fluid inlet, use bushing
(12) to allow connection of the swivel adapter (13).
1. See F
IG. 1. Assemble the bushing (12, if needed)
and swivel adapter (13) to the pump inlet. Attach the
suction hose kit (16) to the adapter.
2. Screw one branch of the 3-way valve (14) into the
1/4 npt port of the adapter (13). Attach the drain
hose (15) to the opposite branch of the valve.
3. Assemble the knob (20), reducer nipple (9), bushing
(6), and the male end of the swivel (8) to the back
pressure valve (5). Screw the swivel (8) onto the
middle threads of the 3-way valve.
4. Attach the fluid filter kit (22) as follows:
a. On pumps with a 3/8 npt fluid outlet, screw the
female end of the swivel (17) onto the pump out-
let fitting. Screw the fluid filter kit (22) inlet onto
the male end of the swivel. The bushing (18) is
not needed.
b. On pumps with a 3/4 npt fluid outlet, screw the
female end of the bushing (18) onto the pump
outlet fitting. Screw the fluid filter kit (22) inlet
onto the male end of the bushing. The swivel
(17) is not needed.
c. On pumps with a 1/2 npt fluid outlet, screw the
fluid filter kit (22) inlet directly onto the pump
outlet fitting. The swivel (17) and bushing (18)
are not needed.
5. Ground the pump as explained in your separate
pump manual.
6. Connect the fluid supply line to the fitting at the fluid
filter outlet.
7. Connect the fluid return line (R) to the reducer nip-
ple (9) at the inlet of the back pressure valve (5).
Use the back pressure valve to adjust fluid pressure
in the circulation system.
8. Use the 3-way valve (14) to direct circulating fluid
back to the pump through the adapter (13), or to a
container through the drain hose (15).

tion, maintenance, repair, and parts information.
