Hayward Matrix Hi-Performance Self-Priming Pumps

General Tips on Pump Installation

For best pump performance, locate the system below the pool water line and as close to the pool as possible. For above ground pools, consult Note: NSPI-4 Article V for safe and proper installation of the equipment package. Ensure suction joints are tight. Suction pipe should be as large or larger than discharge pipe.

Avoid damp, non-ventilated locations. Motors require free circulation of air for cooling.

Ensure the electrical supply agrees with the motor's voltage, phase, and cycle, and that wire size is adequate for the HP/KW rating and distance from the power source. The motor must always be properly grounded. If cord-connected, use a properly grounded outlet. Electrical circuits should be protected by a proper size ground fault circuit interrupter (GFCI). All electrical wiring should be performed by qualified personnel and must conform to local codes and regulations.

Starting and Priming Instructions

Fill strainer/housing completely with water. Never operate the pump without water, as water acts as a coolant and lubricant for the mechanical shaft seal.

Open all suction and discharge lines and valves, as well as air bleed (if available) on the filter. This allows displaced air from the suction line to escape.

Turn on power and allow adequate time for priming. Priming time depends on suction lift and length of suction piping. If the pump will not start or prime, refer to the TROUBLE SHOOTING GUIDE.

Note: NSPI-4 Article V, standard for above ground and on ground pools, advises that components such as the filtration system, pumps and heater be positioned so as to prevent their being used as a means of access to the pool by young children.

Maintenance

1. Clean strainer basket regularly. Do not strike the basket to clean. Inspect strainer cover gasket regularly and replace as necessary.
2. Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.
3. Keep motor housing clean. Ensure air vents are free from obstructions, debris, etc.
4. Occasionally, shaft seals must be replaced due to wear or damage. Refer to instructions for replacement.

Storage/Winterizing

Protect the pump and motor from freezing. Shut off all electric power. Disconnect cord/electrical connections and plumbing connections. Drain thoroughly and clean out any debris. Store the pump and motor in a dry, well-ventilated room.

Selecting Pump's Discharge Position (4 Steps)

Your Hayward Power-Flo® Matrix™ pump can be easily positioned for horizontal or vertical water discharge. This procedure can be performed while the pump is mounted to the base.

1. Remove ALL plumbing attached to the pump.
2. Remove the strainer housing: Disengage and lift off the strainer cover. Remove the strainer basket. Lift up on the strainer 'C' clip and remove. Slide the strainer housing forward and remove.
3. Press the positioning button located on the pump housing and rotate the discharge port to the desired position. (NOTE: The discharge port will only rotate 1/4 turn.)
4. Assemble the pump by following the above directions in the reverse manner.

2 Speed Electronic Timer Module Instructions

Your integrated timer module is designed to be programmed to your filtration needs, with four (4) possible settings:

Programmations:

• Setting 1 - Pump runs on high 24 hours continuously - (1 beep)
• Setting 2 - Pump runs on high 18 hours and on low for 6 hours - (2 beeps)
• Setting 3 - Pump runs on high 12 hours and on low for 12 hours - (3 beeps)
• Setting 4 - Pump runs on high 6 hours and on low for 18 hours - (4 beeps)

When the pump is switched from position "off" to "program", a beep sound is heard. This allows the pumps to differentiate between settings.

To Set Timer:

1. Move switch from "off" to "program" to "off" produces 1 beep.
2. Move switch from "off" to "run".
3. Repeat the above two steps accordingly to your choice of setting.

If a power failure occurs: After power is restored, the time will automatically default to the programmed mode, adding the length of time the power failure occurred.

IMPORTANT SAFETY INSTRUCTIONS

PLEASE READ AND FOLLOW ALL INSTRUCTIONS

When servicing electrical equipment, basic safety precautions should always be observed, including the following. Failure to follow instructions may result in injury.

• WARNING - To reduce the risk of injury, do not permit children to use this product.
• Disconnect all electrical power service to the pump before beginning shaft seal replacement.
• Only qualified personnel should attempt rotary seal replacement. Contact your local authorized Hayward Dealer or service center if you have any questions.
• The National Electrical Code requires either a three (3) foot maximum twist-lock cord set with a GFCI protected receptacle or hard wire (conduit) connection for swimming pool pump installation. Do not use extension cords.

SAVE THESE INSTRUCTIONS

Exercise extreme care in handling both the rotating and the stationary sections of the two-part replacement seal. Foreign matter or improper handling will easily scratch the graphite and ceramic sealing surfaces.

1. Shut off water flow to the pump by closing appropriate valves or by plugging both the skimmer outlet port and return port to the pool. Disconnect piping or hoses from the motor/pump assembly.
2. Remove the strainer by disengaging and removing the strainer cover. Remove the basket. Lift up on the strainer 'C' clip and remove. Finally, slide the strainer housing forward and remove.
3. Unscrew eight (8) screws and remove the pump cover, exposing the impeller.
4. Remove the canopy or the shaft cover plate from the end of the motor opposite the impeller.
5. Hold the motor shaft securely by either inserting a screwdriver in the slot at the end of the shaft or by using an open-end wrench to engage the flat surfaces provided near the end of the motor shaft. Rotate the impeller in a counterclockwise direction and remove it from the motor shaft.
6. Note how the steel spring section of the old seal is positioned on the impeller hub and remove it by pulling from the impeller.
7. Loosen four (4) motor through bolts from the back of the motor and remove the pump housing/shroud from the front of the motor.
8. Remove the ceramic stationary portion of the old seal by pressing the white ceramic seat out of the pump housing recess. If the assembly is tight, tap lightly from the "motor" side.
9. Clean and lubricate the impeller stem and the pump housing recess with a dilute solution of non-granulated liquid-type soap. Do not use petroleum or silicone lubricants as these can contribute to seal leakage.
10. Press the new rotating portion of the seal assembly onto the impeller stem with the polished black graphite surface facing away from the impeller.
11. Carefully press the stationary ceramic portion of the seal into the recess of the pump shroud, with the polished flat surface facing out.
12. Carefully insert the motor shaft through the pump housing and align with the white ceramic stationary seal assembly in place and secure the motor to the pump housing with the four (4) motor through bolts removed in step #7. Be sure the motor base and pump discharge port are positioned properly. Alternately tighten the motor through bolts until the pump housing is secure. Make certain the motor shaft turns freely before proceeding.
13. Screw the impeller (clockwise) with the rotating portion of the seal in place onto the motor shaft. Hand-tighten the impeller in place.
14. Clean (replace if necessary) the O-ring and replace it on the pump housing. Assemble the pump cover to the pump shroud with the four (4) screws removed in step #3. Tighten screws alternately and evenly.
15. Re-assemble the strainer by sliding the strainer housing onto the pump cover. Install the strainer 'C' clip by pushing the clip down onto the grooved pump cover coupling. Insert the basket and fasten the strainer cover.
16. Reconnect the pump to the piping or hoses provided. Open all valves and make sure that the pump strainer housing is full of water before restarting the pump.

Trouble Shooting Guide

A. MOTOR WON'T START

1. Check for improper or loose connections, open switches or relays, blown circuit breakers or fuses.
2. Manually check rotation of motor shaft for free movement and lack of obstruction.

B. MOTOR CUTS OUT – Check for:

1. Wiring, loose connections, etc.
2. Low voltage at motor (frequently caused by undersized wiring).
3. Binding and overload (Amperage reading).

NOTE: Your Hayward pump motor is equipped with Automatic Thermal Overload Protection. The motor will automatically shut off, under normal conditions, before heat build-up due to an improper operating condition can occur. The motor will auto-restart when safe heat level is reached.

C. MOTOR HUMS BUT DOES NOT START – Check for:

1. Centrifugal switch stuck in open position.
2. Binding of motor shaft.

D. PUMP WON'T PRIME

1. Make sure pump/strainer housing is filled with water, and that the cover O-Ring is clean and properly seated. Make sure the strainer cover is locked firmly in position.
2. Make sure all suction and discharge valves are open and unobstructed, and that the pool water level is above all suction openings.
3. If the pump develops a vacuum, check for a blocked suction line or strainer, or an air leak in the suction piping.
4. If the pump does not develop a vacuum and the pump has sufficient "priming water":
   • Tighten all bolts and fittings.
   • Check voltage to make sure the pump is up to speed.
   • Open the pump and check for clogging and obstruction.
   • Remove and replace the shaft seal.

E. LOW FLOW – Generally, Check for:

1. Clogged or restricted strainer or suction line; undersized pool piping.
2. Plugged or restricted discharge line of the filter (high discharge gauge reading).
3. Air leak in suction (bubbles issuing from return fittings).
4. Pump operating underspeed (low voltage).
5. Plugged or restricted impeller.

F. NOISY PUMP – Check for:

1. Air leak in suction causing rumbling in the pump.
2. Cavitation due to restricted or undersized suction line and unrestricted discharge lines. Correct the suction condition or throttle discharge lines, if practical.
3. Vibration due to improper mounting, etc.
4. Foreign matter in pump housing.
5. Motor bearings made unserviceable by wear, rust, or continual overheating.
