INSTALLATION AND SERVICE MANUAL

WARNING! IMPORTANT SAFETY INSTRUCTIONS!

READ CAREFULLY BEFORE INSTALLATION

CALIFORNIA PROPOSITION 65 WARNING:

This product and related

accessories contain chemicals known to the

State of California to cause cancer, birth defects

or other reproductive harm.

FAILURE TO FOLLOW THESE

INSTRUCTIONS AND COMPLY

WITH ALL CODES MAY CAUSE

SERIOUS BODILY INJURY

AND/OR PROPERTY DAMAGE.

1) Before installing or servicing

your pump, BE CERTAIN THE PUMP

POWER SOURCE IS TURNED OFF

AND DISCONNECTED.

2) All installation and electrical wiring must

adhere to national, state and local codes. Check with

appropriate community agencies, or contact your local

electrical and pump professionals for help.

3) CALL AN ELECTRICIAN WHEN IN DOUBT.

Pump must be connected to a dedicated electrical

circuit directly from the entrance box. There must

be an appropriately sized fuse or circuit breaker in

this line. Tying into existing circuits may cause circuit

overloading, blown fuses, tripped circuit breakers or

a burned-up motor.

4) Do not connect pump to a power supply until the

pump is grounded. For maximum safety, a ground fault

interrupter should be used. CAUTION: FAILURE TO

GROUND THIS UNIT PROPERLY MAY RESULT

IN SEVERE ELECTRICAL SHOCK.

5) WARNING: Reduced risk of electric shock

during operation of this pump requires the provision

of acceptable grounding if the means of connection

to the supply-connection box is other than grounded

metal conduit. Ground the motor back to the service by

connecting a copper conductor, at least the size of the

circuit conductors supplying the motor, to the ground

screw provided within the wiring compartment of the

motor.

6) The voltage and phase of the power supply must

match the voltage and phase of the pump motor.

7) Do not use an extension cord.

8) Never operate a pump with a frayed or brittle

power cord, and always protect it from sharp

objects, hot surfaces, oil and chemicals. Avoid

kinking the cord.

9) Never service a motor or power cord with

wet hands or while standing in or near water or

damp ground.

10) The three phase units must be wired by a

qualified electrician, using an approved starter box and

switching device.

11) Do not use this pump in, or in close proximity

to, any body of water such as to allow physical contact

with both the pump and with water.

12) Single phase motors are equipped with

automatic resetting thermal protectors. The motor may

restart unexpectedly, causing the leads to energize or

pump to turn. Three phase motors should be protected

by proper, thermal and amperage protection. (Check

local codes.)

13) Do not pump gasoline, chemicals, corrosives

or flammable liquids; they could ignite, explode or

damage the pump, causing injury and voiding

the warranty.

14) Do not run this pump with the

discharge completely closed. This will

create superheated water, which could

damage the seal and shorten the life

of the motor. This superheated water

could also cause severe burns.

15) The following may cause

severe damage to the pump and

void warranty. It could also result in

personal injury:

• Running the pump dry.

• Failure to protect the pump

from below freezing temperatures.

• Running the pump with the discharge

completely closed.

• Pumping chemicals or corrosive

liquids.

16) Never work on the pump or system without

relieving the internal pressure.

17) Do not pump water above 140°Fahrenheit

(60° Celsius) with plastic impeller. Brass impeller

version is rated to 212° Fahrenheit (100° Celsius).

18) Never exceed the pressure rating of any system

component.

19) Not intended to be permanently connected to

water mains and not connected by hose set.

20) This appliance is not intended for use by

persons (including children) with reduced physical,

sensory or mental capabilities, or lack of experience

and knowledge, unless they have been given

supervision or instruction concerning use of the

appliance by a person responsible for their safety.

21) Children should be supervised to ensure that

they do not play with the appliance.

INSTALLATION

MOUNTING

Stationary - Pump to be securely mounted to a level

rigid base using the four slots provided on the motor

foot bracket. The slots will accommodate 3/8" or 10mm

mounting bolts.

Pump should be located where flooding cannot occur.

PIPING

Pipes must line up and not be forced into position by

unions. Piping should be independently supported

near the pump so that no strain will be placed on

the pump casing. Where any noise is objectionable,

pump should be insulated from the piping with

rubber connections. Always keep pipe size as large

as possible and use a minimum of fittings to reduce

friction losses.

SUCTION PIPING

Suction pipe should be direct and as short as possible.

It should be at least one size larger than suction inlet

tapping and should have a minimum of elbows and

fittings. The piping should be laid out so that it slopes

upward to pump without dips or high points so that

air pockets are eliminated. The highest point in the

suction piping should be the pump inlet except where

liquid flows to the pump inlet under pressure. If a foot

valve must be used to keep pump primed, where liquid

flows to the pump, it may be desirable to use a check

valve in the suction line or discharge line to keep pump

primed.

To prevent air from being drawn into suction pipe

due to a suction whirlpool, the foot valve should be

submerged as least three feet below the low water

level. The suction pipe must be tight and free of air

leaks or pump will not operate properly.

DISCHARGE PIPING

Discharge piping should never be smaller than pump

tapping and should preferably be one size larger. A

gate valve should always be installed in discharge line

for throttling if capacity in not correct. To protect the

pump from water hammer and to prevent back flow, a

check valve should be installed in the discharge line

between the pump and gate valve.

ELECTRICAL CONNECTIONS

Be sure motor wiring is connected for voltage being

used. Unit should be connected to a dedicated circuit,

direct from main switch. A fused disconnect switch

or circuit breaker must be used in this circuit. Means

for disconnection of all poles must be incorporated in

the fixed wiring according with the wiring rules. Wire

of sufficient size should be used to keep voltage drop

to a maximum of 5%. All motors, unless provided with

built-in overload protection, must be protected with an

overload switch, either manual or magnetic. Single

phase 1/2 hp – 2-1/2 hp motors have built-in overload

protection. Never install a pump without proper

overload protection. When motor is mounted on a

base plate or on slide rails for adjustment, flexible

metallic conduit should be used to protect the motor

leads. Three phase motors must have a protective

device installed in the fixed wiring.

Damaged supply cord replacement is intended to be

made by the manufacturer, its service agent or similar

qualified person to avoid hazard.

PRIMING

The pump must be primed before starting. The pump

casing and suction piping must be filled with water

before starting motor. Remove vent plug in top of

casing while pouring in priming water. A hand pump or

ejector can be used for priming when desired. When

water is poured into pump to prime, use care to remove

all air before starting motor.

STARTING

Close the discharge valve when starting the pump as

it puts less starting load on the motor. When the pump

is up to operating speed, open the discharge valve to

obtain desired capacity or pressure. Do not allow the

pump to run for long periods with the discharge valve

tightly closed. If the pump runs for an extended period

of time without liquid being discharged, the liquid in the

pump case can get extremely hot.

ROTATION

The pump must run in direction of the arrow on pump

case. All single phase motors are single rotation and

leave factory with proper rotation. Three phase motors

may run either direction. If rotation is wrong when

first starting motor, interchange any two leads to

change rotation.

STOPPING

Before stopping pump, close the discharge valve. This

will prevent water hammer and is especially important

on high head pumps.

FREEZING

Care should be taken to prevent the pump from

freezing during cold weather. It may be necessary,

when there is any possibility of this, to drain the pump

casing when not in operation. Drain by removing the

pipe plug in the bottom of the casing.

ROTARY SEAL

CT pumps are fitted only with a rotary seal. This

seal is recommended for water free from abrasives.

If liquid contains abrasives, the CT pump should not be

used.

DISASSEMBLY INSTRUCTIONS

All pumping parts can be removed from case without

disturbing the piping.

POWER SUPPLY

Open the power supply switch contacts and remove

fuses. Disconnect the electrical wiring from the motor.

VOLUTE CASE

Drain pump case by removing drain plug.

Remove the cap screws securing volute case to

pump bracket.

Pry volute case from seal plate.

IMPELLER

Remove motor end cover.

Loosen clamp holding start capacitor and swing

capacitor off to one side; do not disconnect wires.

Wrench flats are on the shaft just behind the centrifugal

switch that is screwed into the end of the shaft. Do not

remove this switch. A 7/16" open end wrench can then

be used to hold the shaft

from turning.

Grasp the impeller and turn counterclockwise

(as viewed from the pump end).

SEAL

Remove the rotating part of the seal by pulling it off the

shaft.

The stationary seat can be pressed from the

seal plate.

ASSEMBLY INSTRUCTIONS

All pump parts should be cleaned thoroughly before

being reassembled.

MOTOR

Assure that the rubber slinger is in place on the

motor shaft.

SEAL

A new pump seal should always be used when

rebuilding a pump.

Apply some light oil to the rubber that surrounds the

ceramic stationary seat. Insert the seal seat into the

seal plate using finger pressure to press firmly and

squarely until it bottoms. Care must be taken to keep

grease and dirt off face areas of the seal. Be sure the

seal faces are not damaged during assembly (cracked,

scratched or chipped) or the seal will leak.

Position the seal plate into the motor flange. Use care

not to chip the stationary seal seat by hitting the motor

shaft.

Carefully press the rotating seal assembly onto the

motor shaft. The smooth face of the carbon ring must

contact the ceramic seat. The rubber ring must seal

against the shaft.

IMPELLER

Hold the motor shaft and check that the rubber ring of

the seal is positioned on the shaft.

Turn the impeller clockwise onto the shaft.

Replace the capacitor taking care not to pinch any

wires and tighten capacitor clamp and replace motor

end cover taking care not to pinch any wires.

VOLUTE

Assure that a new or good condition gasket is in place

on the seal plate.

Carefully position the volute in alignment over the

impeller and seal plate.

Assemble the components. The bottom two cap screws

must also pass through the bracket.

RESTARTING OPERATION

The pump must be primed before starting. The pump

volute and suction piping must be filled with water

before starting motor. A hand pump or ejector can be

used for priming when desired.

Reconnect electrical power.

After a few minutes of operation, check that there is no

leakage from the pump or piping.

TROUBLESHOOTING
