WARNING
Always follow the
Pressure Relief Procedure
Warning
on page 8 before doing any repair.
Priming Valve & Tube
(See Fig 9)
NOTE:
Each new priming valve kit includes a priming
tube and fittings.
1. Unscrew the nut on the handle (E) of the priming
valve. Unscrew the stem of the handle.
2. Screw the priming valve (10a) out of the pump hous-
ing (9).
3. Wrap the threads of the priming valve with
r
tape as shown in Fig 9.
Screw the valve
snugly into the pump housing. The valve handle
must be parallel with the angled edge of the housing
to avoid interference with the inlet or outlet valves.
4. Slide the nut (10d) and ferrule (10c) onto the tube
(10e). Install the tube support (10b) in the end of the
tube. Screw the nut onto the priming valve, which will
seat the ferrule.
5. Completely screw the stem of the handle (E) onto the
priming valve, and then back it out two turns. Screw
the nut hand tight onto the priming valve, then tighten
the stem into the valve.
Suction Tube
(See Fig 9)
1. Unscrew the nut (45) from the fluid inlet valve hous-
ing (1). Remove the hose clamp (47). Slit the suction
hose to free the nipple (46).
2. Insert the nipple (46) through the nut (45). Dampen
the new hose (44) with warm water. Press the hose
over the nipple. Screw the nut onto the inlet valve
housing. Press the hose onto the nipple, leaving
about a 1/8 in. (3 mm) gap between the nut and hose
end.
3. Install the hose clamp (47) and tighten snugly.
4. Remove the filter housing (48) and strainer (49) from
the old suction hose and install them on the new
hose. Soften the hose with warm water to
ease
assembly.
