INSTALLATION
(See Figure 1)
A. Install the check valve in the pump discharge port as
shown. Tighten with care and DO NOT overtighten. Slide
one square-cut O-Ring over the check valve discharge
port. Follow it with the discharge pipe.
B. Turn the water box cover upside down and install the
gasket around the edge of the flange, cleat side up. Insert
the capscrews up through the holes in the flange and
gasket. Insert the second square-cut O-Ring in the port
that is 2" from its nearest corner.
C. Set the pump in one corner of the water box as shown. Be
sure the float switch is unobstructed and free to move.
D. Turn the cover right side up and run the cords through the
non-threaded hole in the cover as shown.
E. Put the cover on the water box, making sure that the
discharge pipe from the pump seats in the port with the
square-cut O-Ring. The pump should not move in the
water box when you do this.
F. Secure the cover with the 8 capscrews and washers.
Compress the gasket material; do not overtighten. The
cleats on the corners of the gasket should hook over the
edge of the water box flange; if you catch the cleats
between the box and the cover, the box will leak.
G. Gently pull the slack out of the electrical cords. Slip the
grommet over the cords and slide it down the cords. Press
the grommet into the hole in the cover (lip up).
H. Install the inlet pipe in the opening as shown. Use RTV
sealant or Plasto-Joint Stik to seal threads. See Figures 2,
3 and 4 for typical installation arrangements.
I. Thread the end of the exterior discharge pipe down into
the 1-1/2" NPT hole in the cover that has the discharge
from the pump in it. You should install a union to allow
easy removal for service.
J. Thread a 1-1/2" NPT exterior vent pipe into the second
hole in the water box cover. Connect the vent pipe to the
sewer vent system. You should install a union to allow
easy removal for service.
K. Test the system by filling the water box with water and
running the pump through one complete cycle.
Risk of electrical shock. Do not handle
pump or pump motor with wet hands. If basement floor
is wet, do not walk on wet area until all power is turned
off. If shut-off box is in basement, call the electric com-
pany to shut off service to the house, or call your local
fire department for instructions. Remove pump and
repair or replace. Failure to follow this warning can
result in fatal electrical shock.
Always electrically ground pump motor to a suitable
electrical ground such as a grounded water pipe or a
properly grounded metallic raceway system, or to a
ground wire system.
Do not cut round grounding prong off of plug.
Unplug pump before attempting to service or remove
any component.
Install according to local and national electrical codes.
