this product. This information should be given to the owner and/or operator of this equipment after installation
or left on or near the pump.

Attention User: This manual contains important information that will help you in operating and maintaining
this pump. Please retain it for future reference.

WARNING — Before installing this product, read and follow all warning notices and instructions which

are included. Failure to follow safety warnings and instructions can result in severe
injury, death, or property damage. Call [phone] (US) or 0032-14-259900

(Europe) for additional free copies of these instructions.

Consumer Information and Safety

The EQ Series pumps are designed and manufactured to provide many years of safe and reliable service when
installed, operated and maintained according to the information in this manual and the installation codes referred
to in later sections. Throughout the manual, safety warnings and cautions are identified by the “ “ symbol.

Be sure to read and comply with all of the warnings and cautions.

DANGER — Risk of electrical shock or electrocution.

This pool pump must be installed by a licensed or certified electrician or a qualified
pool serviceman in accordance with the National Electrical Code and all applicable
local codes and ordinances. Improper installation will create an electrical hazard which
could result in death or serious injury to pool users, installers, or others due to
electrical shock, and may also cause damage to property.

Always disconnect power to the pool pump at the circuit breaker before servicing the
pump. Ensure that the disconnected circuit is locked out or properly tagged so that it
cannot be switched on while you are working on the pump. Failure to do so could result
in serious injury or death to serviceman, pool users or others due to electric shock.

WARNING — Do not operate the pump until you have read and understand clearly all the operating

instructions and warning messages for all equipment that is a part of the pool
circulating system. The following instructions are intended as a guide for initially
operating the pump in a general pool installation, however each installation may have
unique conditions where the starting procedure could be different. Failure to follow all
operating instructions and warning messages can result in property damage or severe
personal injury or death.

EQ Series Pump Installation and User’s Guide

IMPORTANT SAFETY PRECAUTIONS (continued)

WARNING — Never exceed the maximum operating pressure or temperature limits of the system

components. Pumps installed with the EQ Strainer Pot Assembly should not be tested at a
pressure that exceeds the value written on the EQ Strainer Pot. See the Owner's Manual
that accompanies that product for more instructions. Ensure that pressures higher than
those required in the pressure test cannot inadvertently be applied to the circulation
system. This may require the use of a pressure regulator between the water supply and the
circulation system.

Changes in temperature or barometric pressure can cause the internal test pressure to
increase or decrease over time once the system is isolated. A pressure relief device
should be installed that would prevent the pressure from exceeding the intended test
pressure. Exceeding these limits could result in a component failing under pressure. This
instantaneous release of energy can cause failed components to be accelerated to high
velocities and to travel distances of 100 feet or more. These components could cause
severe personal injury or death if they were to strike a person.

WARNING — Due to the potential risk that can be involved it is recommended that the pressure test be

kept to the minimum time required by the local code. Do not allow people to work around
the system when the circulation system is under pressure test. Post appropriate warning
signs and establish a barrier around the pressurized equipment. If the equipment is located
in an equipment room, lock the door and post a warning sign.

iii

Never attempt to adjust any closures or lids or attempt to remove or tighten bolts when the
system is pressurized. These actions can result in a separation or failure of system
components. This instantaneous release of energy can cause components to be
accelerated to high velocities and to travel distances of 100 feet or more. These
components could cause severe personal injury or death if they were to strike a person.

CAUTION — This pump is for use with permanently installed pools and may also be used with hot tubs

and spas if so marked. Do not use with storable pools. A permanently installed pool is
constructed in or on the ground or in a building such that it cannot be readily disassembled
for storage. A storable pool is constructed so that it may be readily disassembled for
storage and reassembled to its original integrity.

IMPORTANT SAFETY PRECAUTIONS (continued)

General Installation Information

WARNING — Pumps improperly sized or installed or used in applications other than for which the pump

was intended can result in severe personal injury or death. These risks may include but not
be limited to electric shock, fire, flooding, suction entrapment or severe injury or property
damage caused by a structural failure of the pump or other system component.

WARNING — The pump can produce high levels of suction within the suction side of the plumbing

system. These high levels of suction can pose a risk if a person comes within the close
proximity of the suction openings. A person can be seriously injured by this high level of
vacuum or may become trapped and drown. It is absolutely critical that the suction
plumbing be installed in accordance with the latest national and local codes for swimming
pools.

• These instructions contain information for a variety of pump models and therefore some instructions may
not apply to a specific model. All models are intended for use in swimming pool applications. The pump will
function correctly only if it is properly sized to the specific application and properly installed.

• The pump is available with or without a specially designed strainer pot assembly. If a suction strainer pot
assembly is to be provided, it should comply with NSF-50 standards. Pumps without the strainer pot
assembly are not self-priming and must be installed so that the pump is always flooded with water. If the
pump is to be installed without a strainer pot, plumbing suction inlets must prevent debris larger tha

0.6 cm ( ¼”) in diameter from being drawn into the pump.

• Pumps installed with the specially designed strainer pot assembly are self-priming at heights up to
3 meters (10 feet) depending on the specific installation.

Introduction

EQ Series® High Performance Commercial Pump Overview

The EQ Series pumps deliver extraordinary performance in every key aspect. They're built to last, of
course, and are also built to be incredibly efficient, quiet, lightweight and corrosion-resistant. All of this adds
up to a pump that is highly cost effective and suited for a wide range of commercial water applications.

At the heart of the EQ's extraordinary performance is its unique impeller design. It provides two significant
benefits. First, it means more efficient performance — the EQ pump moves more water more quickly than
comparable pumps. And secondly , it means the pump's motor doesn't have to work as hard and, as a result,
runs cooler and lasts considerably longer.

What's more, the Pentair EQ pump has been through a rigorous design, development and testing program
so you know it's built to handle the toughest commercial applications for years to come.

A vailable in single and three-phase, 50 and 60 Hz models, the EQ sets the new standard for performance in
pumps. No one else in the industry has made a plastic injection-molded pump with performance like this for
pool and water applications.

EQ Series Pump Installation and User’s Guide

Section 2

Installation

The following general information describes how to install the EQ Series pump.

Note: Before installing this product, read and follow all warning notices and instructions starting
on page ii.

Installing the EQ Series Pump

Only a qualified service person should install the EQ Series pump.

Mechanical Installation and Pressure Testing

Mechanical Installation

1. Carefully remove the pump unit and strainer pot assembly, if included, from its shipping package.

3

2. The pump will perform best when the suction and return head losses (Total Dynamic Head (TDH)) of the pool

system have been carefully determined and the correct pump model selected to fit these requirements. A pump
should be selected to operate near the center of its Performance Curve with as high an efficiency as possible.
It is also important that the Net Positive Suction Head Available (NPSHA) be greater than the Net Positive
Suction Head Required (NPSHR) at the design flow rate.

3. If it is not possible to determine accurate suction and discharge head losses (Total Dynamic Head (TDH)),

conservative plumbing practices should be strictly adhered to. This would include installing the pump as close
to the pool as possible and at approximately the same level as the pool water level. (See page iv., General
Installation Information, regarding when a strainer pot assembly is required.) Use large diameter pipe especially
on the suction line to keep flow velocities at or below 1.8 meters per second (mps), (6 feet per second (fps)).
Flow velocities in the return plumbing should not exceed 3 mps (10 fps). Also keep elbows and tees to a
minimum. Installations where the pump is going to be installed more that 3 meters (10 feet) below or 1.5 meters
(5 feet) above the pool water level must be evaluated by an experienced professional to ensure that the pump
will function correctly.

4. A solid flat foundation should be provided to support the pump. The area should be well drained so that the pump

motor will not be flooded under any circumstances. Ensure that adequate space and lighting around the pump
is provided for routine maintenance activities.

NOTE

Do not install the pump motor within 1.5 meters (5 feet) of the inside walls of the pool wall unless the pump bears the UL
listing mark. UL listed pumps may be installed within 1.5 meters (5 feet) of the inside walls of a swimming pool, spa or
hot tub only if a solid copper bonding conductor not smaller than No. 10 SWG (No. 8 AWG) is connected from a bonding
lug wire connector on the motor to all metal parts of the swimming pool, spa or hot tub structure and to all electrical
equipment, metal conduit, and metal piping within 1.5 meters (5 feet) of the inside walls of the swimming pool, spa or hot
tub.

5. It is good practice for most installations to install a valve on both the suction and return line so that the pump can

be isolated for routine maintenance. However, a valve, elbow or tee installed in the suction line should be no closer
to the front of the pump than 5 times the suction line pipe diameter. (i.e. 15.2 cm (6”) pipe requires a 7.6 meters
(30 “) straight run in front of the suction inlet of the pump.)
