Installation (Continued)
8. Motor has automatic internal
thermal overload protection. If
motor has stopped for unknown
reasons, thermal overload may
restart it unexpectedly, which could
cause injury or property damage.
Disconnect power before servicing
motor.
9. If this procedure or the wiring
diagrams are confusing, consult a
licensed electrician.
Operation
PRIMING THE PUMP
NOTE:
'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, damaging seal and possibly
causing burns to persons handling pump.
Fill pump with water before starting.
1. Remove priming plug.
2. Make sure suction and discharge
valves and any hoses on discharge
side of pump are open.
3. Fill pump and suction pipe with
water (See Figure 7).
4. Replace priming plug, using Teflon
tape on thread; tighten plug.
NOTE:
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).
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 horizontal run.
NOTE:
(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 priming plug, refill
and try again.
NEVER 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 (See Figure 8).
Replacing the priming plug with a
pressure gauge (purchased separately)
will help monitor pressure so that it is not
allowed to exceed maximum pumping
pressures according to performance chart.
To prevent explosion, do the following:
1. Be sure discharge (valve, pistol grip
hose nozzle, etc.) is open whenever
pump is running.
2. If pump fails to produce water when
attempting to prime, release all
pressure, drain pump, and refill with
cold water after every attempt.
3. 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.
4.
Make sure discharge pipe and
zone size are large enough for
this pump’s performance.
Maintenance
Pump and piping need not be
disconnected to repair or replace motor
or seal (See Figure 10). If motor is
replaced, replace the shaft seal (Ref No.
6, Pages 9 and 10). Keep one on hand
for future use.
Be sure to prime pump before starting.
NOTE:
Check motor label for
lubrication instructions. The mechanical
shaft seal in the pump is water
lubricated and self-adjusting.
NOTE:
Drain pump when disconnecting
from service or when it might freeze.
