SECTION 2. General Information

2A. Introduction

This manual contains information for the proper

installation and operation of Jandy™ 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.

2B. Description

Jandy™ 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, 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.

Two Speed Pump Models- The hydraulic performance and priming of Jandy™ two speed pumps will be the same at high speed as the same model single speed pump. At low speed the pump will produce one half (½) the flow, and one quarter (¼) the pressure of high speed. The pressure required by the filter and pool plumbing at half flow will also be greatly reduced, due to much lower system friction. These lower friction losses result in increased energy savings. At one half flow (low speed) the electrical energy savings are 60% for equal amounts of circulated water.

Pool owners should use high speed for vacuuming the pool, quick filtering action, priming the heating system, and to keep up with heavy bathing loads. Spa owners will want to use high speed for good jet action.

SECTION 3. Preparation and Location

3A. Pump Preparation

1. Upon receipt of the Jandy™ 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 part lists on Pgs. 9-12.

3B. 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.

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

should be located a minimum of 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.

Turn the motor to low speed for quiet operation

and electrical cost savings. Since the pump should be operated at low speed for cost savings, minor adjustments may be required in the automatic chlorine dispenser, the skimmers and the heater due to the lower flow (see the equipment manufacturer's operation manuals).

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.

8. If the equipment is under cover, provide adequate lighting.

SECTION 4. Piping Design & Installation

4A. 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".

4B. 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.

4C. 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.

4. The Jandy™ Pump must be connected to at least two 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.

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.

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. The Jandy™ Pump comes equipped with 2" 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

5A. Check for Correct Voltage

1. The correct voltage, as specified on the pump nameplate 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 nameplate operating voltage to the pump, by ensuring proper circuit sizes and wire sizes for this specific application.

Caution

Failure to provide nameplate voltage during operation within 10% will cause motor overheating and void the warranty .

5B. 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.

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

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.

5C. Electrical Wiring

1. The pump motor must be securely and adequately grounded using the green screw provided. Ground before attempting to connect to an electrical power supply. Do not ground to

a gas supply line.

2. Wire size must be adequate to minimize voltage drop during starting and operation of the pump. See Table 2 for suggested wire sizes.

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.

W ARNING

Always disconnect the power source before working on a motor or its connected load.

SECTION 6. Start-up

6A. Pump Start-up

Caution

Never run the pump without water. Running the pump "dry" for any length of time can cause severe damage to both the pump and motor.

1. If this is a new pool installation, make sure all piping is clear of construction debris and has been properly pressure tested. The filter should be checked for proper installation, verifying all connections and clamps are secure according to the manufacturer's recommendations.

2. Release all pressure from the system and open the filter pressure release valve.

3. If the pump is located below the water level of the pool, opening the filter pressure release valve will prime the pump with water.

4. If the pump is located above the water level of the pool, remove the lid and fill the basket with water before starting the pump.

5. Prior to replacing the lid, check for debris around the lid o-ring seat. Debris around the lid o-ring seat will cause air to leak into the system, and make it difficult to prime the pump.

6. Clean the lid o-ring and place on the lid.

11. The pump should prime. The time it takes to prime will depend on the elevation and length of pipe used on the suction supply pipe. See section 4 "Piping Design & Installation" for proper elevation and pipe size.

12. If the pump does not prime and all the instructions to this point have been followed, check for a suction leak.

SECTION 7. Use and Maintenance

7A. General Maintenance

1. The pump will collect any large debris present in the water at the pump basket. As this debris accumulates it will begin to block the flow of water through the pump, and must be removed. The cleaner the basket is kept, the more effective and efficient the pump will perform. The pump lid is clear for easy inspection between cleaning.

2. To clean the basket, turn off the power to the pump. If the pump is located below the water level, close the isolation valves on the suction and discharge sides of the pump to prevent backflow of water. Turn the lid counterclockwise until it comes off. You may use a tool for leverage to remove the lid, but NEVER to tighten the lid.

Caution

A misaligned basket will cause the lid to be improperly seated, allowing an air leak which could result in pump damage.

7. Hand tighten the lid to make an air tight seal. Do not use any tools to tighten the lid, hand tighten only.

8. Make sure all valves are open and the unions are tight.

9. Turn on the pump.

10. Once all the air has left the filter, close the pressure release valve.

3. Lift the basket out of the pump.

4. Dispose of the debris and thoroughly clean the basket, making sure all the holes are open. Using a garden hose, spray the basket from the outside to help clear the holes. Use your hands to remove any remaining debris.

5. Replace the basket in the pump by aligning the opening with the suction pipe. If aligned properly, the basket will drop easily into place,

do not force.

6. Prior to replacing the lid, check for debris around the lid o-ring seat, as this will cause air leaks into the system. Clean the lid o-ring and place on the lid.

7. Hand tighten the lid to make an air tight seal. Do

not use any tools to tighten the lid, hand tighten only.

8. Verify that all valves have been returned to the proper position for pumping.

9. Open the pressure release valve on the filter, and make sure it is clean and ready for operation.

10. Turn on the power to the pump. Once all the air has been evacuated from the filter, close the pressure release valve.

7B. Winterizing the Pump

1. When freezing temperatures are expected, the Jandy™ Pump must be protected. Allowing the pump to freeze will cause severe damage and void the warranty.

loosened and the pump stored indoors. For safety, and to prevent entry of contaminants, reinstall all conduit and terminal box covers.

7. When the system is reopened for operation, make sure all piping, valves, wiring, and equipment are in accordance with the manufacturer's recommendations. Pay close attention to the filter and electrical connections.

8. The pump must be primed prior to starting, in accordance with the "Start-up" instructions (Section 6) contained in this manual.

SECTION 8. Troubleshooting

8A. Troubleshooting

1. Water Pik Technologies, Inc. recommends that you call a qualified service technician to perform any repairs on the filter/pump system. For technical service call 707-776-8200, ext.

260.

2. Do not use antifreeze solutions in the pool, spa, or hot tub systems! Antifreeze is highly toxic and may damage the circulation system. The only exception to this is Propylene Glycol. For more information see your local pool/spa supply store or ask a qualified swimming pool service company.

3. Drain all water from the pump, system equipment, and piping.

4. The pump has two drain plugs that may be removed with a wrench. Do not use a screwdriver to remove or install the drain plugs.

5. Store the drain plugs in a safe location and reinstall them when the cold weather is over. Use a silicone sealant and wrench to tighten the drain plugs.

6. Keep the motor covered and dry. Note: Covering the pump with plastic will create condensation and this moisture will damage the pump. The best way to protect your pump is to have a qualified service technician or electrician properly disconnect the electrical wiring at the switch or junction box. Once the power is removed, the two unions can be

2. The cleaning/circulating system is not working as well as in the past. a. Are the skimmer baskets, pump basket and

other screens clean? b. Has the filter been cleaned recently? c. Are all the valves adjusted correctly? Too

much equipment on at one time will stop

many cleaners from working (waterfalls, spa

jets, surface returns, etc.). d. Have you checked the cleaning system

manual to make sure it is adjusted according

to the manufacturer's recommendations.

3. Are there bubbles present in the pump basket? a. Check the pool or spa water level to make

sure it is at the proper level and that air is not being drawn into the suction piping. If the water is normal, continue with the next step.

b. Turn off the pump. Remove the lid. Check

for debris around the lid o-ring seat, as this will cause air leaks into the system. Clean the lid o-ring and place on the lid. Hand tighten the lid to make an air tight seal. Do NOT use any tools to tighten the lid. Turn on the pump.

Page 10

Water Pik Technologies, Inc.

4. If there are still air leaks check the suction side piping union. a. While the pump is running, try to tighten the

union. If this does not stop the air leak,

continue to the next step. b. Turn off the pump. c. Loosen both unions and slide the pump out

of the way. d. Remove, clean and place both union o-rings. e. Reposition the pump next to the piping and

secure the union nuts to the pump. With

clean union o-rings, hand tightening of the

unions should create a seal. If the unions still

do not seal, gently tighten with a large

tongue-and-groove pliers. DO NOT over

tighten.

5. If there is no air in the system, but the pressure is still low. a. It is possible that debris is caught in the

pump impeller. The Impeller is what moves the water and has vanes that can become blocked with debris. See "Blocked Impeller" (Section 9A) under the "Specialty Service" section of this manual.

7. The pump is leaking water between the motor and pump body. a. This is caused by a damaged or failed

mechanical seal. To solve this problem, the seal must be replaced. See "Mechanical Seal Replacement" under "Speciality Service" section of this manual.

8. The pump gets hot and shuts off periodically. a. Make sure the motor has plenty of room to

circulate air and keep cool. Have a qualified electrician check for loose connections and check the voltage at the pump motor while it is in operation. The voltage must be within 10% of the motor's nameplate rating. If it is not, then a qualified electrician and/or the power company needs to get involved to resolve the problem.

SECTION 9. Specialty Service

TWater Pik Technologies, inc. recommends that

you call a qualified service technician to perform any repairs on the filter/pump system.

6. If there is nothing blocking the impeller and the pressure is still low. There are three other possible reasons for this; a. The pump has been in an abrasive

environment for a long period of time, and the impeller and diffuser are showing signs of wear. If the problem is normal wear on the Impeller and diffuser, have a qualified service technician replace them.

b. If this is a relatively new installation, it could

be an electrical problem. This problem can be easily identified by a qualified service technician. Have the technician check for loose electrical connections and check the voltage at the pump motor while it is in operation. The voltage must be within 10% of the motor's nameplate rating. If it is not, then a qualified electrician and/or the power company needs to get involved to resolve the problem.

c. Pump seal is leaking air. Have a qualified

service technician replace the seal.

WARNING

While servicing the pump, switch off the circuit breakers at the power source. Severe personal injury or death may occur if the pump starts while your hand is inside the pump.

9A. Blocked Impeller

1. Turn off the pump. Switch off the circuit breaker to the pump motor.

2. Remove the lid and basket.

3. Look inside the pump for any debris. Remove any debris found inside.

4. Replace the basket and lid.

5. Switch on the circuit breaker to the pump motor.

6. Turn on the pump, and see if the problem is solved.

7. If the impeller is still blocked with debris and it is not possible to remove the debris this way, the pump will need to be disassembled to access the inlet and outlet of the impeller.
