Product Manual

INSTALLATION
Risk of electrical shock. Can burn or kill. Do
not lift pump by power cord. See “Cord Lift Warning” on
Page 3.
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" (457 mm) in
diameter and 30" (762 mm) deep.
Piping:
Piping must not be smaller than pump discharge.
When installed in a sewage system, pipe must be capable of
handling semi-solids of at least 2" (51mm) diameter.
When installed in an effluent system, pipe must be capable
of handling semi-solids of at least 3/4" (19 mm) diameter.
The rate of flow in the discharge pipe must keep any solids
present in suspension in the fluid. To meet minimum flow
requirements of 2 ft. per second (61 cm/sec) in discharge
line, size pipe as follows:
A Pipe Size Of: Will Handle a Flow Rate Of:
2" (51 mm) 21 GPM (79.5 L/M)
2-1/2" (64 mm) 30 GPM (113.5 L/M)
3" (76 mm) 48 GPM (182 L/M)
In a sewage system use a 2" (51 mm) min. check valve
in pump discharge to prevent backflow of liquid into sump
basin. The check valve should be a free flow valve that will
easily pass solids. Be sure check valve installation complies
with local codes.
In an effluent system use a 1-1/2" (38 mm) min. check valve
in pump discharge to prevent backflow of liquid into pump
basin. The check valve should be a free flow valve that will
easily pass solids. Be sure check valve installation complies
with local codes.
NOTICE: For best performance of check valve when handling
solids, do not install it with discharge 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" (5 mm) hole in discharge pipe about 1 to 2"
(25-50 mm) 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 below.
1. DO NOT splice the power cord, submerge electrical cord
plug, or use extension cords.
2. DO NOT handle or service pump while it is connected to
power supply.
3. DO NOT operate pump unless it is properly grounded.
Wire pump directly into grounded terminal block in
automatic float or pump controller box. Power cord
on 1-phase units is a 3-wire conductor with 3-prong
grounding-type plug. Do not modify cord or plug. When
using with plug-in receptacle, plug pump into a 3-wire,
grounded, grounding-type receptacle only. Connect pump
according to all applicable codes.
For automatic operation, plug or wire pump into an automatic
float switch or pump controller. For continuous operation,
plug directly into an electrical outlet or wire directly into
switch box. Connect pump to its own individual branch circuit
with nothing else on the circuit. See Specifications Chart
(Page 2) for fuse or circuit breaker sizes.
Risk of electrical shock and fire. Be sure
that power supply information (Voltage/Hertz/Phase) on
pump motor nameplate matches incoming power supply
exactly. Install pump according to all electrical codes
that apply.
The automatic float switch on Model S50HTPC1 is factory set
with a 4" tether length. This tether length can be adjusted to
accom modate a variety of pumping ranges. (See performance
graph, Page 3). The installer must ensure that the switch
does not become obstructed and that the range is set so the
liquid level remains a minimum of 2" above pump suction at
the lowest level, and below the basin inlet pipe at the highest
level.
