STA-RITE 400S Series User manual

Carefully read and follow all safety instructions in
this manual or on pump.
This is the safety alert symbol.
When you see this symbol on your pump or in this manual,
look for one of the following signal words and be alert to
the potential for personal injury.
warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
warns about hazards that can cause serious
personal injury, death or major property damage if ignored.
warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are
important but not related to hazards.
1. Read these rules and instructions carefully. Failure to
follow them could lead to serious bodily injury and/or
property damage.
2. Check your local codes before installing. You must
comply with their rules.
3. Vent sewage or septic tank according to local codes.
4. Do not install pump in any location classified as
hazardous by local codes.
Risk of electrical shock. Can burn
or kill. Do not lift pump by power cord. See “Cord Lift
Warning” on Page 3.
Hazardous voltage. Can shock,
burn, or cause death. During operation the pump is
in water. To avoid fatal shocks, proceed as follows if
pump needs servicing:
5A. Disconnect power to outlet box before pulling pump
cord plug.
5B. Take extreme care when changing fuses. Do not stand
in water or put your finger in fuse socket.
5C. Do not modify cord and plug. When using cord and
plug, plug into a grounded outlet only. When wiring to
a system control, connect pump ground lead to system
ground.
6. Do not run pump dry. Dry running can overheat pump,
(causing burns to anyone handling it) and will void war-
ranty.
7. Pump normally runs hot. To avoid burns when servic-
ing pump, allow it to cool for 20 minutes after shut-
down before handling it.
8. In normal service, motor should not need oiling. Motor
has been filled at the factory with a special oil; when
overhauling, replace with new oil. Use only oil speci-
fied in parts list of this manual. Use of any other oil
could damage motor and will void warranty.

SAFETY INSTRUCTIONS

INSTALLATION
NOTICE: Install pump on a hard, level surface (cement,
asphalt, etc.). Never place pump directly on earth, clay or
gravel surfaces.
Piping
When installed in a sewage system, pipe must be capable of
handling semi-solids of at least 51mm (2") diameter.
The rate of flow in the discharge pipe must keep any solids
present in suspension in the fluid. To meet minimum flow
requirements [61 cm (2 feet) per second in discharge line],
size pipe as follows:
A Pipe Size Of: Will Handle a Flow Rate Of:
38 mm (1-1/2") 45 LPM (12 GPM)
51 mm (2") 79 LPM (21 GPM)
63.5 mm (2-1/2") 113 LPM (30 GPM)
76 mm (3") 181 LPM (48 GPM)
In a sewage system use a 51mm (2") 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 han-
dling 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 5mm (3/16") hole in discharge pipe about 25-51mm
(1-2") 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 submerged.
3. DO NOT use extension cords. They are a fire hazard and
can reduce voltage sufficiently to prevent pumping
and/or damage motor.
4. DO NOT handle or service pump while it is connected 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 ground-
ed plug. Plug pump into a 3-wire, grounded, grounding-
type receptacle. Connect pump according to local codes.
A non-automatic pump will run continuously when connect-
ed to a power supply. An automatic pump will start and stop
dependent upon water level.
Connect or wire pump to its own circuit with no other out-
lets or equipment in the circuit. Size fuses or circuit break-
ers according to chart above, right.
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.

Operation and Installation
NOTICE: Do not allow 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
motor from burning out due to overheating/overloading.
When motor cools down, overload protector will automati-
cally reset and start motor.
If overload trips frequently, check for cause. It could be a
stuck impeller, wrong/low voltage, or electrical failure in
motor. If an electrical failure in the motor is suspected,
replace pump.
Pump is permanently lubricated. No oiling or greasing is
required.
SERVICE
General
Hazardous voltage. Can shock, burn,
or cause death. Before removing pump from basin for
service, always disconnect electrical power to pump and
control switch.
Risk of electrical shock. Can burn or
kill. Do not lift pump by power cord. See “Cord Lift
Warning” on Page 3.
Submerge complete pump in a disinfectant solution (chlorox
or chlorine) for at least one hour before disassembling
pump.
Impeller Replacement
1. Unplug cord from power source.
2. Remove screws from lower volute housing (Key #1) and
separate volute halves.
3. Hold shaft with screwdriver in slot in end of shaft;
unscrew impeller (Key #2) counter clockwise from shaft.
4. Thread new impeller onto shaft. Hold shaft with screw-
driver and tighten impeller firmly hand tight.
5. Remount lower volute housing (Key #1).
6. Plug in unit.
7. Pump is ready for operation. To avoid flooding, test
pump before operating by filling sump and running pump
through one complete cycle to be sure that switch works.

Sudden Starts. If power is on to pump
when thermal overload resets, pump may start
without warning. If you are working on pump, you
may get an electrical shock or impeller may catch
fingers or tools. Disconnect power before servicing
pump.

A. Pump fails to operate: 1. Check to be sure that power cord is securely plugged into outlet or securely wired
into controller or switch box. Disconnect power to outlet before handling pump
or motor.
2. Check to be sure you have electrical power.
3. Check that liquid fluid level is high enough to activate switch or controller.
4. Check to be sure that there is a 5mm vent hole in discharge pipe and it is not
plugged.
5. Check for blockage in pump inlet, impeller, check valve or discharge pipe.
6. Thermal overload may have tripped. Test start pump; if it starts and then stops
immediately, disconnect from power source for 30 minutes to allow motor to cool,
then reconnect to power source. Check for cause of overheating/overloading.
B. Pump fails to empty sump: 1. Be sure all valves in discharge valve are fully open.
2. Clean out discharge pipe and check valve.
3. Check for blockage in pump inlet or impeller.
4. Pump not sized properly. A higher capacity pump may be required.
C. Pump will not shut off: 1. Check switch or controller automatic floats for proper operation and location.
See installation instructions for switch/controller.
2. If pump is completely inoperative or continues to malfunction, consult your
local serviceman.
