Wayne SPT33, CDT33, SPT50, CDT50, SSPT50 User Manual

Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the product described.
Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or
property damage! Retain instructions for future reference.

Description

The submersible pump is designed for
home sump applications. The unit is
equipped with an 8-ft long, 3-prong
grounding type power cord. Motor is
oil filled and sealed for cooler running
and designed to operate under water.
A float switch is provided for automatic
pump operation. This pump is not
suitable for aquatic life.

Unpacking

Inspect this unit before it is used.
Occasionally, products are damaged
during shipment. If the pump or
components are damaged, return the
unit to the place of purchase for
replacement. Failure to do so could
result in serious injury or death.

General Safety
Information

Do not use to pump
flammable or explosive
fluids such as gasoline, fuel
oil, kerosene, etc. Do not
use in a flammable and/or explosive
atmosphere. Pump should only be used
to pump clear water. Personal injury
and/or property damage could result.

This pump is not

designed to handle
salt water, brine, laundry discharge or
any other application which may
contain caustic chemicals and/or foreign
materials. Pump damage could occur if
used in these application and will void
warranty.

All wiring must be

performed by a
qualified electrician.

If the basement has water
or moisture on the floor,
do not walk on wet area
until all power is turned

off. If the shutoff box is in the
basement, call an electrician. Remove
pump and either repair or replace.
Failure to follow this warning could
result in fatal electrical shock.

A backup

system should be
used. Call 1-800-237-0987 for backup
model number.

Installation

1. Install pump in a sump pit with

minimum size as shown below.
Construct sump pit of tile, concrete,
steel or plastic.

2. The unit should be located and rest

on a solid, level foundation. Do not
place pump directly on clay, earth,
gravel or sandy surface. These
surfaces contain small stones,
gravel, sand, etc. that may clog or
damage the pump and cause pump
failure.

Flood risk. If

flexible discharge
hose is used, make sure pump is
secured in sump pit to prevent
movement. Failure to secure pump
could allow pump movement and
switch interference and prevent pump

from starting or stopping.

3. Thread (optional) check valve
(Wayne No. 66005-WYN)into pump
body carefully to avoid stripping or
cross threading. Do not use pipe
joint sealant.

4. Connect 1-1/4” rigid pipe to rubber
boot on check valve. Reverse boot
for 1-1/2” diameter pipe. Tighten
hose clamps.

Support pump and

piping when
assembling and after installation.
Failure to do so could cause piping to
break, pump to fail, etc. which could
result in property damage and/or
personal injury.

5. Protect electrical cord from sharp

object, hot surfaces, oil and
chemicals. Avoid kinking the cord
and replace damaged cords
immediately.

IMPORTANT: Make sure there is
adequate room for tether switch to
swing freely during operation.

6. A sump pit cover must be installed

to prevent debris from clogging or
damaging the pump.

Operation

Always disconnect the
power source before
attempting to install,
service, relocate or
maintain the pump. Never touch sump
pump, pump motor, water or discharge
piping when pump is connected to
electrical power. Never handle a pump
or pump motor with wet hands or when
standing on wet or damp surface or in
water. Fatal electrical shock could
occur.

1. A ground fault circuit interrupter

(GFCI) is required.

4. Fill sump with water. The pump will
start automatically when the water
has filled the sump to a depth of
approximately 13“. The pump will
stop when the water depth is
approximately 7”. The pump will
recycle thereafter as required.

5. Do not operate the pump unless it is
submerged in water. Dry running
causes pump failure.

6. The motor is equipped with an
automatic reset thermal protector.

7. While the pump is draining the pit,
verify that the discharge piping is
carrying the water to a point several
feet away from the foundation.

8. If pump discharge line is exposed to
freezing temperature, the exposed
line must be pitched to drain.
Trapped water will freeze and
damage the pump.

Maintenance

Always disconnect the
electrical supply before
attempting to install,
service, relocate or
perform any maintenance. If the power
source is out of sight, lock and tag in

supplied with a grounding conductor
and grounding type attachment plug.
Use a grounded receptacle to reduce
the risk of fatal electrical shock.

Never cut off the round grounding
prong. Cutting the cord or plug will
void the warranty and make the pump
inoperable.

2. This pump is only for use on 120
Volt (single-phase), 60 hz, 15 amp
service and is equipped with a 3­conductor cord and 3-prong,
grounding type plug. Insert the
float switch cord plug directly into
a 120 volt outlet.

3. Insert the pump power cord plug
directly into the back of the float
switch cord plug (See Fig. 2).

2. Plugged impeller

1. If blown, replace with proper sized fuse or reset breaker.

2. If voltage is under 108 volts, check wiring size.

3. Replace pump

4. Replace float switch

5. If impeller will not turn, remove housing and remove blockage

6. Make sure float move freely up and down

1. Install or replace check valve (Wayne No. 66005-WYN)

2. Replace float switch

1. Replace float switch

2. Remove pump and clean pump and piping

3. Make sure float moves freely up and down

1. If voltage is under 108 volts, check wiring size.

2. Clean out impeller

the open (off) position to prevent
unexpected power application. Failure
to do so could result in fatal electrical
shock. Only qualified electricians
should repair this unit. Improper repair
could result in fatal electrical shock.

1. Let the pump cool for a minimum
of two hours before servicing
because the pump contains hot oil
under pressure and the motor is
hot.

2. Disassembly of the motor prior to
expiration of warranty will void the
warranty. If repairs are required,
see troubleshooting chart.

4. Inlet should be kept clean and free
of all foreign objects and inspect
annually. A clogged inlet will
damage pump.

5. Pump should be checked monthly
for proper operation.

This pump contains

dielectric oil for
cooling. This oil can be harmful to the
environment. Check the state
environmental laws before disposing
this oil.
