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).
[gl, CAUTION [NEVER run pump dry. Running
pump with-
out water
may cause pump to overheat,
damaging sea[
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
va]ves and any
hoses on discharge
side of pump are open.
Step _. Fill pump
and suction
pipe with water
(Figure 6).
IJikWARNING
INEVER
run pump against closed discharge.
To do so can boil water
inside pump, causing
hazardous
pressure in unit, risk of explosion
and possibly scalding
persons handling
pump (Figure
7). Replace priming plug
with
pressure gauge to monitor
pressure so that it is not
allowed
to exceed maximum
pumping
pressures accord-
ing to performance
chart.

Step 4. Replace priming
plug, using Teflon tape on
thread; tighten
plug.
NOTICE:
If priming
tee and plug have been pro-
vided for long horizontal
run, be sure to fill suc-
tion pipe through
this tee and
replace
plug. (Use
Teflon tape on plug.)
Step 5. Start pump;
water should
be produced
in 10 min-
utes or less, time depends
on depth to water (not
more than 20' (6 m)) and length of horizontal
run
(10' (3 m) of horizontal
suction
pipe = 1' (_0.5
cm) of vertical
lift due to friction
losses in pipe).
If no water
is produced
within
10 minutes,
stop
pump,
release all pressure,
remove printing
plug,
refill and try again.
NOTICE:
Open
water system faucets before printing
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 nozzle,
etc.) is open whenever
pump
is running.
Step B. If pump fails to produce
water when attempting
to prime,
release all pressure, drain pump
and
refill with cold water after every
attempt.
Step C. When priming,
monitor
pump body and piping
temperature.
Motor will
warm up; this is normal.
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
and piping
with cold water.
Step D. Make sure discharge
pipe and zone
size are not
too small
for this pumps
performance.
