MY861-R (06-25-20)
This submersible utility pump is designed for draining water
from basement floors, stock tanks, window wells, boats, flat
roofs and cisterns. Unit is equipped with a 3-prong grounding-
type power cord. Shaded-pole motor is oil filled and sealed for
cooler operation. Sleeve bearings on the motor shaft never need
lubrication. Also includes automatic reset thermal protection.
INSTALLATION
1. Set the pump on a hard surface in at least 2” of water.
2. Connect the discharge line with the fittings provided.
3. The pump should not be installed on clay, dirt, mud or
sand surfaces as they can clog the pump and reduce it’s
performance.
Although the pump will usually pass small particles
suspended in water, clean the area to be pumped of small
stones and gravel which could clog the pump. Keep the
pump inlet screen clean.
4. To reduce motor noise and vibrations when using rigid
pipe, a short length of rubber hose (e.g. radiator hose) can
be connected into the discharge line near the pump using
suitable clamps.
5.
and requires a minimum 15 amp. individual branch circuit.
Pump is supplied with a 3-wire cord with grounding-type
plug.
Risk of electric shock. Can shock, burn or
kill. Pump should always be electrically grounded to a
suitable electrical ground such as a grounded water pipe
or a properly grounded metallic raceway, or ground wire
6. If the pump discharge line is exposed to an outside
sub-freezing atmosphere, the line exposed must be
installed so any water remaining in pipe will drain to the
outfall by gravity. Failure to do this can cause water trapped
in the discharge line to freeze which could result in damage
to pump.
7. Check the operation of pump by observing through one
complete cycle.
OPERATION
The shaft seal depends on water for lubrication. Do not
operate pump unless it is submerged in water as seal may be
damaged if allowed to run dry.
During manual operation the pump will pump down to within
1/8” of the pumping surface. If the optional switch is used, the
final water level is determined by placement of the switch.
For long cycle times, the pump must be submerged to prevent
the motor from overheating. A fully submerged pump is
preferred for proper cooling when a pump runs for a long time.
AIRLOCKS
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. This pump
the hole. Leakage from the anti-airlock hole is normal.
If you suspect an airlock, unplug the pump, clean out the anti-
airlock hole with a paper clip or a piece of wire, and restart the
pump.
