ii IMPORTANT SAFETY PRECAUTIONS Important Notice: This guide provides installation and operation instructions for the EQ Series Pump. Consult Pentair Water with any questions regarding this equipment. Attention Installer: This guide contains important information about the installation, operation and safe use of 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.
iii 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.
iv 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.
1 Section 1 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.
2 General Features • EQ Series = Energy Efficient and Quiet • Designed in every detail for maximum efficiency • The only non-corrosive, all-plastic pump designed exclusively for the commercial pool and water applications market • The EQ impeller features an exclusive design that provides true breakthrough performance • Lower load due to efficient impeller design means longer motor life • Cam and Ramp™ lid design with clear lid for added convenience in servicing Additional Features: • Closed co
3 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. 2.
4 Figure 1. 70 DURO NITRILE OR EPDM 1/8" THICK GASKET Mechanical Installation, cont.’d. 6. Assemble the strainer pot assembly, if included, to the pump. Be sure to install the O-Ring (included with the strainer pot assembly) over the protruding plastic ring on the front of the pump housing before mounting the strainer pot. Properly position the strainer pot to the housing and secure in place using the 8 large flange bolts and washers included with the strainer pot assembly.
5 Pressure Testing Certain local codes require that the circulation system be pressure tested with a proof pressure before being commissioned into service or before allowing construction to progress to the next stage. WARNING — Improperly pressure testing a circulation system can involve significant risk of property damage or severe personal injury or death.
6 Pressure Testing, cont’d. 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.
7 Section 3 Electrical Requirements This section describes how to secure and wire the EQ pump. Electrical Requirements and Field Wiring NOTE Do not install the pump motor within 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 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.
8 Electrical Requirements and Field Wiring, cont’d. CAUTION — Some single-phase pumps may contain an internal thermal protector designed to temporarily stop the pump if the motor exceeds a preset temperature. The pump will automatically restart when the motor temperature falls to a preset limit. Always disconnect power before working on the pump to eliminate the possibility that the pump could start unexpectedly.
9 Section 4 Initial Operation of Pump This section describes how to prime the EQ pump. 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.

11 Section 5 Maintenance Cleaning of the Strainer Basket 1. The pump is designed to be maintenance free with the exception of requiring a periodic cleaning of the strainer basket. 2. A routine inspection should be done by visually looking through strainer lid for debris while the pump is in operation. The strainer basket should be cleaned when approximately 25 % blocked.
12 Preventative Maintenance It may be possible to extend the life of the pump and to prevent a pump down situation by implementing a preventative maintenance program. This may be done by periodically performing a list of activities and recording certain information to be able to spot potential problems before they become serious. It is recommended that these activities be performed after the filter cleaning procedure so that the information will be taken from the same baseline each time.
13 Section 6 Servicing WARNING —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.
14 Disassembly 1. Ensure the electric supply circuit is disconnected and is properly tagged and locked out. 2. Disconnect the line supply conductors and the ground conductor from the motor (1) if the motor is being replaced. 3. Close any valves required to prevent flooding when the pump is disassembled. 4. Review the parts breakdown in Section 8, to understand how the pump components are assembled together. 5. Remove the pump housing (22) drain plug (24) and allow the pump to completely drain. 6.
15 Assembly 1. Ensure that the two 6 ½ in. long screws (11) with washers (12) are properly inserted into the bottom of the motor adaptor (7) before attaching the motor adaptor (7) to the new motor (1). 2. Properly orient the motor adaptor (7) to the motor (1) and secure in place using the four screws (10) and washers (8) (9). 3. Insert the two dowel pins (26) into the motor adaptor (7). 4. Install the stationary ring of the mechanical seal (14) into the seal plate bore.
