SPECIFICATIONS
Power Supply Required ..............................115V, 60 HZ
Motor Duty ...................................................Intermittent
Maximum Liquid Temperature..................120° F (49° C)
Individual Branch Circuit Requirement .............15 Amps
Discharge Pipe Size ...............................2" NPT (51mm)
INSTALLATION
NOTICE: Install pump on a hard, level surface (cement,
asphalt, etc.). Never place pump directly on earth, clay
or gravel surfaces. Basin must be at least 18" (457mm)
in diameter. Be sure that switch can swing through its
entire arc without any obstruction.
Piping
Effluent Applications (for 3/4" (19.1mm) or less solids)
Piping must be 1-1/2" (38.1mm) minimum to carry vol-
ume of pump discharge. Check local codes to determine
if a check valve is required in your system. In cold cli-
mates, check valves are not used to prevent effluent
from freezing in piping.
If using as sump pump, a check valve is recommended.
Sewage Applications (for 2" (51mm) or less solids)
In any case, piping must not be smaller than pump dis-
charge.
When installed in a sewage system, pipe must be capable
of handling semi-solids of at least 2" (51mm) diameter.

The rate of flow in the discharge pipe must keep any
solids present in suspension in the fluid. To meet mini-
mum flow requirements (2 feet (.6 m) per second in dis-
charge line) size pipe as follows:
A Pipe Size Of:
1-1/2" (38.1mm)
2" (50.8mm)
2-1/2" (63.5mm)
3" (76.2mm)
Use a 2" (51mm) swing check valve in pump discharge
to prevent backflow of liquid into sump basin. 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.
Drill a 3/16" (4.8mm) hole in discharge pipe about 1–2"
(25.4 - 51mm) above pump discharge connection (but
below check valve) to prevent airlocking the pump.
Electrical
Hazardous voltage. Can shock, burn, or
cause death. When installing, operating, or servicing
this pump, follow safety instructions listed below.
1. DO NOT splice the electrical power cord.
2. DO NOT allow electrical cord plug to be sub-
merged.
3. DO NOT use extension cords. They are a fire hazard
and can reduce voltage sufficiently to prevent pump-
ing and/or damage motor.
4. DO NOT handle or service pump while it is con-
nected to power supply.
5. DO NOT remove grounding prong from plug or
modify plug. To protect against electrical shock, the
power cord is a three-wire conductor and includes a
3-prong grounded plug. Plug pump into a 3-wire,
grounded, grounding-type receptacle. Connect pump
according to electrical codes that apply.
