PRIMING THE PUMP
NOTICE: 'Priming' refers to pump expelling all air in the
system and beginning to move water from its source
out into system. It does not refer only to pouring water
into pump (although pouring water in is usually the first
step).
NEVER run pump dry. Running pump
without water may cause pump to overheat, dam-
aging seal and possibly causing burns to persons
handling pump. Fill pump with water before starting.
Step 1. Remove priming plug.
Step 2. Make sure suction and discharge valves and
any hoses on discharge side of pump are open.
Step 3. Fill pump and suction pipe with water (Fig. 4).
Step 4. Replace priming plug, using Teflon tape on
thread; tighten plug.
NOTICE: If priming tee and plug have been
provided for long horizontal run, be sure to fill
suction pipe through this tee and replace plug.
(Use Teflon tape on plug.)
Step 5. Start pump; water should be produced in 10
minutes or less, time depends on depth to water
(not more than 20' (6 m)) and length of horizon-
tal run (10' (3 m) of horizontal suction pipe = 1'
(30.5 cm) of vertical lift due to friction losses in
pipe). If no water is produced within 10 minutes,
stop pump, release all pressure, remove prim-
ing plug, refill and try again.
NEVER run pump against closed dis-
charge. To do so can boil water inside pump, caus-
ing hazardous pressure in unit, risk of explosion
and possibly scalding persons handling pump (Fig.
5). Replace priming plug with pressure gauge to
monitor pressure so that it is not allowed to exceed
maximum pumping pressures according to perfor-
mance chart.
NOTICE: Open water system faucets before priming
pump for the first time.
Remove priming plug.
Step A. Fully open control valve (turn counterclockwise).
Step B. Fill pump and suction pipe with water.
Step C. Replace priming plug, using Teflon tape on plug
thread; tighten plug.
To prevent explosion, do the following:
Step A. Be sure discharge (valve, pistol grip hose noz-
zle, etc.) is open whenever pump is running.

If pump body or piping begin to feel warm to
touch, shut off pump and allow system to cool.
Release all pressure in system and refill pump
