IMPORTANT

For best possible performance and continuous, satisfactory operation,

read these instructions before installing your new pump.

Should service be required, this manual can be a valuable guide.

It should be kept near the installation for ready reference.

Record nameplate data from pump on blank nameplate inside this

manual for future reference.

READ AND FOLLOW

SAFETY INSTRUCTIONS!

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 will or 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 label NOTICE indicates special instructions which

are important but not related to hazards.

Carefully read and follow all safety instructions in

this manual and on pump.

Keep safety labels in good condition.

Replace missing or damaged safety labels.

LOCATION:

Locate the pump as near to the water source as

practical. Make the suction pipe run short and straight

with as few pipe fittings as possible to keep total friction

loss to a minimum.

Install pump in a clean, dry and well drained location

if possible and protect against moisture and adverse

weather conditions. Pump should be located on a level,

hard surface to prevent shifting or tipping. Locate to be

readily accessible for inspection and maintenance.

Careful attention should be taken to assure that Net

Positive Suction Head Available (NPSHA) exceeds Net

Positive Suction Head Required (NPSHR) by the pump

or reduced performance and severe pump damage may

result.

Figure 1, Page 3, illustrates where these terms (NPSHA

/ NPSHR) originate, and how to determine if the

pumping conditions at which you want to operate meet

the proper criteria. When in doubt, consult your nearest

Berkeley Professional Dealer.

NOTE: If pump site is 1000 feet above sea level,

sub-tract 1.2 feet from the NPSHA equation and an

additional 1.2 feet for each additional 1000 feet of

elevation.

General Safety

Do not allow pump, piping, or any other system

component containing water to freeze. Freezing may

damage system, leading to injury or flooding. Allowing

pump or system components to freeze will void

warranty.

Pump approved liquids only with this pump.

Periodically inspect pump and system components.

Wear safety glasses at all times when working on

pumps.

Keep work area clean, uncluttered and properly lighted;

store properly all unused tools and equipment.

Keep visitors at a safe distance from the work areas.

WARNING

Rotating parts. Can catch

hands, feet, or clothing.

Stay clear of equipment and

keep shields in place while

pump is running.

Stop motor or engine before

servicing pump.

Read owner’s manual before

using equipment.

Electrical Safety

WARNING Wire motor for correct

voltage. See “Electrical”

section of this manual

and motor nameplate.

Ground motor before

connecting to power

supply.

Meet National Electrical

Code and local codes

for all wiring.

Follow wiring

instructions in

this manual when

connecting motor to

power lines.

Can shock, burn, or

cause death.

General Information

Installation

FOUNDATION: Refer to illustration on Page 4.

Heavy weights; risk of bodily harm due

to crushing. Use care and proper lifting equipment

when handling pump for installation. Size and weight of

some units will require hoists for safe handling.

Pump should be set on a concrete foundation which is

sufficiently substantial to absorb vibration and which

provides a permanent and rigid support.

When properly positioned, the unit will be level, and

the suction and discharge openings of the pump will be

aligned with system piping.

PIPING:

System piping should be at least one commercial pipe

size larger than pump connections and flow velocity

should not exceed eight (8) feet per second. Suction

and discharge pipes must be naturally aligned with

pump connections.

NOTICE: Misalignment of piping with pump case or

excessive pipe strain can cause distortion of pump

components resulting in rubbing, breakage and reduced

pump life.

Insure that piping is supported in a manner that prevents

the exertion of force on pump connections. This can be

checked by the following procedure. With the pump shut

down, remove pipe flange bolts. If the mating flanges

come apart or shift, misalignment is present and causing

pressure on the connections. Adjust pipe supports until

flanges mate without any force. This procedure can be

done throughout piping system.

SUCTION PIPING:

Refer to illustrations on Page 8 through Page 11 for

recommended and not recommended practices in

suction connections.

DISCHARGE PIPING:

Refer to illustrations on Pages 12 through 13 for

recommended and not recommended practices in

discharge connections.

ELECTRICAL CONNECTION:

If electric motor is used.

NOTE: All wiring should be done by a qualified

electrician.

Hazardous voltage. Can shock, burn, or

cause death. Disconnect power to pump

before servicing.

Check voltage and phase stamped on pump motor

nameplate before making wiring connections to

electrical system. Be sure they agree with your electric

current supply. They MUST be the same. If in doubt,

check with your local power company.

Refer to illustration on Page 7 for minimum recom-

mended pumping panel components that help

safeguard your pump during operation.

Proper belt tension varies with the size of belt being

used, however a general rule is:

Belts are properly tensioned when one belt can be

depressed one belt thickness at the center of the

span when pressing with thumb.

Another method is that a properly tensioned belt can

be rotated (twisted) one-quarter revolution at the

center of span.

NOTICE: Belts must be tight enough to prevent slip-

ping during operation. Loose belts result in early belt

failure and reduced performance. However, excessive

tightness of belts will result in overheating of the belts

and excessive bearing load in the pump and driver.
