INSTALLATION

Hazardous voltage. Can shock, burn or kill.

Do not lift pump by the power cord. See “Cord Lift Warning”

on Page 3.

NOTICE: Install the pump on a hard, level surface (cement,

asphalt, etc.). Never place the pump directly on earth, clay or

gravel surfaces.

Piping

Piping must not be smaller than pump discharge.

When installed in an

effluent system, the pipe must be

capable of handling semi-solids of at least

3/4" (19mm) in

diameter.

The rate of flow in the discharge pipe must keep any solids

present in suspension in the fluid. To meet minimum flow

requirements (2 feet per second in the discharge line), size

the pipe as follows:

A Pipe Size Of:

Will Handle a Flow Rate Of:

1-1/2" (38mm)

12 GPM

2" (51mm)

21 GPM

2-1/2"(64mm)

30 GPM

3"(76mm)

48 GPM

In an

effluent system use a 1-1/2" (38mm) 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.

NOTICE: For best performance of check valve when

handling solids, do not install it with the discharge more than

45° above the horizontal. Do not install the check valve in a

vertical position as solids may settle in the valve and prevent

it from opening on startup.

Drill a 3/16" (5mm) hole in the discharge pipe about 1–2"

(25-51mm) above the pump discharge connection (but below

check valve) to prevent airlocking the pump.

Electrical

Hazardous voltage. Can shock, burn, or

kill. When installing, operating, or servicing this pump, follow

the safety instructions listed below.

DO NOT splice the electrical power cord.

DO NOT allow the electrical cord plug to be submerged.

DO NOT use extension cords. They are a fire hazard and

can reduce voltage sufficiently to prevent pumping and/or

damage motor.

DO NOT handle or service the pump while it is

connected to the power supply.

DO NOT remove the grounding prong from the plug

or modify the plug. To protect against electrical shock,

the power cord is a three-wire conductor and includes

a 3-prong grounded plug. Plug the pump into a 3-wire,

grounded, grounding-type receptacle. Connect the pump

according to the NEC or CEC and local codes.

For automatic operation, plug or wire the pump into an

automatic float switch or duplex controller. The pump will run

continuously when plugged directly into an electrical outlet.

S50HTPC1 requires switch panel PW217-280.

Connect or wire pump to its own individual branch circuit

with no other outlets or equipment in the circuit. Size fuses

or circuit breakers according to the “Motor, Switch and Cord

Specifications” chart.

Risk of electrical shock and fire. Can

burn, kill or cause property damage. 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.

Performance Graph – Tether Length vs. Pumping Range

OPERATION

The automatic float switch on Model S50HTPC1 is factory

set with a 4" tether length. This tether length can be

adjusted to accommodate a variety of pumping ranges.

(See performance graph.) 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.

Risk of fire or explosion. Can cause severe

personal injury, property damage or death. Do not use in

explosive atmospheres. Pump water only with this pump.

NOTICE: Do not allow the pump to run in a dry sump. It will

void the warranty and may damage the pump.

An automatic overload protector in the motor will protect

the motor from burning out due to overheating/overloading.

When the motor cools down, the overload protector will

automatically reset and start the motor.

If the overload trips frequently, check for the cause. It could

be a stuck impeller, wrong/low voltage, or an electrical failure

in the motor. If an electrical failure in the motor is suspected,

have it serviced by a competent repairman.

The pump is permanently lubricated. No oiling or greasing is

required.
