Priming The Pump; Operation - Eco-Flo EFLS10 Manual Del Usuario

Hazardous Pressure,
Install pressure relief valve in discharge pipe.
Release all pressure on system before working on
any component.

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).
!
Risk of burns. NEVER run pump dry.
Running pump without water may cause pump to over-
heat, damaging seal and possibly causing burns to per-
sons 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).

Fill pump before starting
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
horizontal run (10' (3 m)) of horizontal
suction pipe = 1' ((30.5 m) 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.

OPERATION

!
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 (Fig. 5). Replace priming plug with pres-
sure gauge to monitor pressure so that is it not allowed to
exceed maximum pumping pressures according to perfor-
mance chart.
Figure 5
Do not run pump with outlet shut off
To prevent explosion be sure discharge (valve, pistol grip
hose nozzle, etc.) is open whenever pump is running.
Monitor pump body and piping temperature. Motor will
warm up; this is normal. If pump body or piping begins
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.
