INSTALLATION
Always use the handle to lift the pump. Never use the power cord to lift the pump. To avoid skin burns,
unplug the pump and allow time for it to cool after periods of extended use.
1.
Install the pump on a solid, level foundation, or in a sump pit constructed of tile, concrete, steel, or plastic. The
recommended minimum diameter of the sump pit is 18" (46cm) diameter and the minimum recommended depth is
30" (76cm). Check local codes for approved materials.
NOTICE:
Pump should not be installed on clay, earth, or sand surfaces.
2.
Secure the pump on a level, solid base. Do not suspend the pump by the discharge pipe, hose, or power cord.
3.
Install 2” discharge pipe into the 2” NPT discharge port. Use rigid plastic pipe and wrap threads with Teflon tape,
NOT pipe joint compound
. Screw pipe into pump hand tight plus 1-1/2 turns.
4.
To reduce motor noise and vibrations, a short length of rubber hose can be connected into discharge line near
pump using suitable clamps.
5.
Install a check valve in the horizontal pipe to prevent flow backwards through the pump when it shuts off. Make
certain the flow indicating arrow points away from the pump. This check valve will keep the water from either
running back into the basin or into the area being pumped out when the pump is not running. Check valve should
be a free flow valve that will easily pass solids.
NOTICE:
For best performance of check valve when handling solids, do not install it with discharge angled more
than 45° above the horizontal. Do not install check valve in a vertical position as solids may settle in valve and
prevent opening on startup.
6.
Drill a 1/8” hole in discharge pipe about 1"-2” (2.5 - 5.1cm) above pump discharge connection (but below check
valve) to prevent air-locking the pump.
7.
A tethered piggyback switch is mounted on the pump. The length of the tether (distance of cord from float to
clamp) should not be set around 3.5 inches and should not be used in a basin smaller than 14 inches in diameter. If
using a differential other than the factory setting, be sure when the pump shuts off at least 4” of fluid is left in the
basin so the impeller remains submerged. Insert the float switch piggy-back plug into a properly grounded outlet
and the pump plug into the piggyback plug.
8.
After the installation of the necessary plumbing, check valve, and rubber hose, follow the glue manufacturer’s
instructions for safety precautions and curing time. The pump is ready for operation.
Pump is designed for 115 V., 60Hz, operation and requires a minimum 15 amp individual branch circuit.
9.
Check the pump by filling the sump pit with water and observe the pump’s operation through one complete cycle.
Make sure the pump cannot move in the sump and float switch moves freely up and down.
