COVER NOT SHOWN
Use 3/8"-16NC x 3/4"
Flanged HHCS and
Flanged Locknuts
9. Power Unit: Put the (4) 5/16”-18NC x 1-1/2” flanged
locking HHCS thru holes in power unit bracket using Push-
Nuts to hold in place, Fig. 8a. Mount unit with motor up to
column bracket and install (2) 5/16” Flanged locking Nuts.
Install and hand tighten Branch Tee to pump until O-ring
is seated. Continue to tighten the locknut to 10-15 ft-lbs.,
or until the nut and washer bottom out against the pump
manifold. NOTE: You may still be able to rotate the Branch
Tee. This is acceptable unless there is seepage at the
O-ring. If so, slightly tighten the locknut.
Over tightening locknut may tear O-ring or
distort threads in pump manifold outlet.
10. Hoses: Clean adapters and hose. Inspect all threads
for damage and hose ends to be sure they are crimped,
Fig. 8b. Install hose and hose clamps, Fig. 9a & Fig. 9d.
Flared Fittings Tightening Procedure
1. Screw the fittings together finger tight. Then, using the
proper size wrench, rotate the fitting 2-1/2 hex flats.
Flare seat MUST NOT rotate when
tightening. Only the nut should turn.
2. Back the fitting off one full turn.
3. Again tighten the fittings finger tight; then using a
wrench, rotate the fitting 2-1/2 hex flats. This will
complete the tightening procedure and develop a
pressure tight seal.
Overtightening will damage fitting resulting
in fluid leakage.
