Receiving inspection
Upon receiving the pump, it should
be
inspected
for
shortages. If damage has occurred,
file a claim immediately with the
company that delivered the pump. If
the manual is removed from the
packaging, do not lose or misplace.
Storage
Any product that is stored for a
period longer than six (6) months
from the date of purchase should be
bench tested prior to installation. A
bench test consists of, checking the
impeller to assure it is free turning
and a run test to assure the motor
(and switch if provided) operate
properly.
Before Installation
Insulation resistance measurement
With the motor and cable (excluding
the power supply cable) immersed in
barmesapumps.com
water, use a megger to measure the
insulation
resistance
ground and each phase of the motor,
and again between each phase of the
motor. The megger should indicate
an insulation resistance of not less
than 20 mega ohms. While making
the measurement, keep the power
supply cable off the ground. We
recommend
that
pump be kept on hand in case of
emergency.
Installation
WARNING
Under no circumstances
should cable be pulled while the
p u m p i s b e i n g t r a n s p o r t e d o r
installed. Attach a chain or rope to the
grip and install the pump.
1. This pump must not be installed
on its side or operated in a dry
condition. Ensure that it is
installed upright on a secure base.
2. Install the pump at a location in
the tank where there is the least
turbulence.
3. If there is a flow of liquid inside
the tank, support the piping
damage
or
where appropriate. Install piping
so that air will not be entrapped. If
piping must be installed in such a
way
unavoidable, install an air release
valve wherever such air pockets
are most likely to develop.
4. Do not permit end of discharge
piping to be submerged, as
backflow will result when the
pump is shut down.
WARNING
(models 2AHS), have an automatic
operating system bump operating
w a t e r l e ve l n e a r t h e m i n i m u m
operating level as the automatic cut-
off switch incorporated inside the
motor will be activated. To avoid dry
operation, install an automatic
operating system, as shown in Figure 1
between
and maintain a safe operating water
level (C.W.L.: continuous water level =
90 mm).
5. For automatic pumps (models
2AHS-A), install the floats as
shown in figure 2. The pump may
not start if a floats switch touches
an
auxiliary
the wall of the water tank or the
piping. Install the floats so that
this will not happen.

connections are secure.
Cable:
WARNING
c) Never let the end of
the cable contact water.
d) If the cable is extended, do not
immerse the splice in water.
e) Fasten the cable to the discharge
piping with tape or vinyl strips.
f ) Install the cable so that it will not
overheat. Overheating caused by
coiling the cable and exposing it to
direct sunlight.
Grounding:
Connect the green wire to ground.
Under no circumstances should the
green wire be connected to the
power supply.
