SECTION 1. Safety Information
1.1 IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:
1. READ AND FOLLOW ALL INSTRUCTIONS
DANGER
2. Do not block pump suction, as this will cause severe or fatal injury if blocked with the body.
WARNING
3. To reduce the risk of injury, do not permit children to use this product unless they are closely supervised
4. Do not attempt to change the multiport valve position with the pump running.
at all times.
5. The Jandy® Pumps are powered by a high voltage electric motor and must be installed by a licensed or certified electrician or a qualified swimming pool service technician.
6. Due to the potential risk of fire, electric shock, or injuries to persons, Jandy® Pumps must be installed in accordance with the National Electric Code, all local electrical and safety codes, and the Occupational Safety and Health Act (OSHA). Copies of the National Electrical Code may be ordered from the National Fire Protection Association, 470 Atlantic Ave., Boston, MA 02210, or contact your local government inspection agency.
7. Incorrectly installed equipment may fail, causing severe injury or property damage.
8. Equipment that is incorrectly pressure tested may fail, causing severe injury or property damage. Pressure testing should only be done by trained pool/spa professionals.
9. Chemical spills and fumes can weaken pool/spa equipment. Corrosion can cause filters and other equipment to fail, resulting in severe injury or property damage. Do not store pool chemicals near your equipment.
CAUTION
10. Do not start pump dry! Running the pump dry for any length of time will cause severe damage
and will void the warranty.
11. 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.
12. Do not install within an outdoor enclosure or beneath the skirt of a hot tub or portable spa.

SECTION 2. General Information
2.1 Introduction
This manual contains information for the proper
installation, operation and maintenance of Jandy Stealth Pumps. Procedures in this manual must be followed exactly. To obtain additional copies of this manual contact us at 707-776-8200, ext. 237. For address information see back cover.
2.2 Description
Jandy® Stealth Pumps are designed to meet the needs of today's more hydraulically demanding pool equipment. The pump housing, seal plate, diffuser, hair and lint pot (pump basket), and impeller are all made from high quality thermoplastic materials. These materials were chosen for their strength and corrosion resistance.
The pump is driven by an electric motor directly attached to the pump impeller. As the electric motor turns it causes the impeller to turn which forces water to flow through the pump. The water flows into the hair/lint pot inlet and through the basket assembly. The basket assembly will pre-strain large particles. The flow then enters the center of the pump housing, goes through the impeller, into the diffuser, and out the pump discharge port.
®
2. If the pump is located below water level, valves should be installed on both the suction and return lines to prevent back flow of pool water during any routine servicing that may be required.
3. The pump and other circulation equipment must be located more than five (5) feet from the water. Choose a location that will minimize turns in the piping.
4. The pump must be placed on a solid foundation that will not vibrate. To further reduce the possibility of vibration noise the pump can be bolted down, or placed on a rubber mat.
5. The pump foundation must have adequate drainage to prevent the motor from getting wet. Protect the pump from the rain and sun.
6. Proper ventilation is required for the pump to operate normally. All motors generate heat that must be removed by providing proper ventilation.
7. Provide access for future service by leaving a clear area around the pump. Allow plenty of space above the pump to remove the lid and basket for cleaning.
SECTION 3. Preparation and Location
3.1 Pump Preparation
1. Upon receipt of the pump, check for carton damage. After opening the carton, check for concealed damage such as cracks, dents or a bent base. If damage is found contact the shipper or distributor where the pump was purchased.
2. Inspect for missing parts, unions, lid, or basket. See the part lists on page 14.
3.2 Pump Location
1. The pump should not be elevated more than a few feet above the water level of the pool, it is best to locate the pump within one (1) foot of the water level. A check valve is recommended on the suction line to the pump.
8. If the equipment is under cover, provide adequate lighting.
SECTION 4. Piping Design & Installation
4.1 Size of Suction Pipe
1. Recommended pipe size for the suction side of the pump is 2" for ¾ to 1½ HP. For 2 HP pumps recommended pipe size is 2½". For 3 HP pumps recommended pipe size is 3".
4.2 Size of Discharge Pipe
1. Recommended pipe size for the discharge side of the pump is 2" for ¾ to 2 HP. For 3 HP pumps recommended pipe size is 2½". Note: All pipe sizes are able to withstand the pressures the pump will deliver, but not the flow. If the pipe is too small for the pump, or it is elevated above water, the maximum gallons per minute (GPM) may not be delivered.

4.3 Installation Tips
1. If the pump is located below water level, it may produce higher pressure compared to an above water installation. Isolation valves must be installed before and after the pump to prevent back flow of pool water during any routine servicing that may be required.
2. To help prevent difficulty in priming, install the suction pipe without high points which can trap air. For installations up to 100 feet from the water, the recommended pipe size must be used. For installations more than 100 feet from the water the recommended pipe must be increased to the next size.
3. Stealth Pumps come equipped with unions on both the suction and discharge ports. This feature will simplify installation, service, and eliminate the possibility of leaks at threaded adapters.
SECTION 5. Electrical Verification & Installation
5.1 Check for Correct Voltage
1. The correct voltage, as specified on the pump data plate, is necessary for proper performance and long motor life. Incorrect voltage will decrease the pump's ability to perform and could cause overheating, reduce the motor life, and result in higher electric bills.
2. It is the responsibility of the electrical installer to provide data plate operating voltage to the pump, by ensuring proper circuit sizes and wire sizes for this specific application.
Caution
Failure to provide data plate voltage (within 10%) during operation will cause motor overheating and void the warranty.
4. The Stealth Pump must be connected to at least two (2) separate suction points in the water. A drain and skimmer, two drains spaced apart, two skimmers, or a skimmer with an equalizer line installed. Check the local codes for proper installation.
5. The piping must be well supported and not forced together where constant stress will be experienced.
6. Always use properly sized valves. Jandy Diverter Valves and Jandy Ball Valves typically have the best flow capabilities.
7. Use the fewest fittings possible. Every fitting added has the effect of moving the equipment farther away from the water. Note: If more than ten (10) suction fittings are needed, the pipe size must be increased.
8. Every new installation must be pressure tested according to local codes.
5.2 Bonding the Motor to the Pool Structure
1. The motor frame must be bonded to the pool/spa structure using a solid copper conductor, No. 8 AWG or larger.
2. Bond the motor using the external lug provided to all metal parts of the pool, spa, or hot tub and to all electrical equipment, metal piping, or conduit within five (5) feet of the inside walls of the pool, spa, or hot tub.
WARNING
Always disconnect the power source before working on a motor or its connected load.
Caution
The pump must be permanently connected to a dedicated electrical circuit. No other equipment, lights, appliances or outlets may be on the pump circuit.
WARNING
Do not pressure test above 35 PSI. Pressure testing must be done by a trained pool professional. Circulation equipment that is not tested properly will fail, resulting in severe injury or property damage.
WARNING
Install the control switch or time clock well away from the pool pump, filter, and other equipment for safety reasons. Should there be an equipment failure or loose fitting, access to the switch away from the failed equipment is important.
