Installation
In any installations where
property damage and/or personal
injury might result from an
inoperative or leaking pump due
to power outages, discharge
line blockage, or any other
reason, a backup system(s)
should be used. In order to
safely use this product, familiar-
ize yourself with this pump and
also with the liquid (chemical,
etc.) that is going to be pumped
through the unit. This pump is
not suitable for many liquids.
1. Pump should be placed as close
to source of liquid and power as
possible, not more than 7 feet
above liquid source and not more
than 25 feet from power source.
2. Use reinforced plastic or fabric
tubing or metal pipe for the
suction side of the pump. This
will prevent collapse of the
suction piping. Discharge piping
should never be larger than
suction piping!
3. Attach suction line piping to the
suction inlet and discharge line
piping to the discharge outlet.
4. Avoid using looped sections of
pipe which might permit air to
become entrapped.
5. Piping should be checked for any
leaks at the connections. Small
leaks in suction line greatly
reduce efficiency of pump and
may prevent priming. Pump
should be permanently mounted;
never operate a pump unless it
is secured to a solid foundation.
6. Do not operate pump dry.
Impeller and mechanical seal
damage will result.
WARNING
7. Protect pump from extreme
heat, cold. and humidity. This
unit is not waterproof and is
not intended to be used in
showers, saunas, or other
potentially wet locations.
8. The motor is designed to be
used in a clean, dry location
with access to an adequate
supply of cooling air. Ambient
temperature around the motor
should not exceed 104°F (40°C).
For outdoor installations motor
must be protected by a cover
that does not block airflow to
and around the motor. This unit
is not weatherproof, nor is it
able to be submersed in water
or any other liquid. Do not use
in or near swimming pool or spa.
9. Install a foot valve and prime
pump when suction lift is over
six feet or when suction line is
longer than six feet.
10. It is strongly recommended that
this unit is plugged into a GFCI
(Ground Fault Circuit Interrupter).
Consult your local electrician
for installation and availability.
Operation
1. Pumps are self-priming and
should prime themselves within
30 seconds after pump is started.
Wetting impeller with pumped
fluid and keeping the impeller
coated with petroleum jelly will
lengthen its life and improve
priming action. Running the
impeller dry for as short as 30
seconds can ruin the impeller. Keep
suction line as short as possible.
NOTE: An easy way to prime the
pump (wet impeller), if using a
garden hose, is to fill the discharge
hose; elevate the discharge hose
slightly to retain water and start
WARNING
the pump. Another method would
be to disconnect the discharge hose
from the pump, making a U-bend
of the discharge hose. Fill the hose
then reconnect (without losing the
water) to the pump. In both cases
the water behind the impeller will
seal the pump and it should prime
almost immediately.
2. Unit can be turned on and off
by plugging & unplugging cord
into 115V outlet.
3. Do not run at heads greater
than 35 feet (15psig).
Because unit is thermally pro-
tected, it is designed to shut off
temporarily in an over-heat
condition; therefore, pumping
extremely hot liquids is not
recommended. Also, to protect
the impeller from breakage, do
not pump liquids with a tem-
perature less than 40°F.
Do not submerge pump or
motor in water.
Maintenance
Make certain the unit is discon-
nected from the power source
before attempting to service or
remove any component!
1. Always drain pump when not
in use.
2. If pump is not going to be used
for a month or longer, flush with
fresh water and remove body
cover, take impeller out, clean
inside body and apply generous
coating of Vaseline
® , to both
inside body and impeller before
replacing impeller in body.
