Flotec AT251001 Centrifugal Pumps With Integral Trap

Product Information

The Flotec Centrifugal Pumps With Integral Trap models AT251001 and AT251501, are designed for use with permanently installed pools, hot tubs, and spas. These pumps create a strong vacuum at the main drain at the bottom of your pool or spa. The suction is so strong that it can trap hair or body, causing severe injury or death. The use of unapproved covers or allowing use of the pool or spa when covers are missing, cracked, or broken can result in body or limb entrapment, hair entanglement, body entrapment, evisceration, and/or death. The pump should be installed and serviced only by a qualified pool service professional. For further assistance, call Flotec Customer Service at 1-800-365-6832.

Product Usage Instructions

• Before using the Flotec Centrifugal Pumps With Integral Trap, read and follow all safety instructions in the owner’s manual and on the pump. Keep safety labels in good condition and replace missing or damaged safety labels. Install a clearly labeled emergency shut-off switch for the pool pump and spa jet pump in an easily accessible, obvious place near the pool or spa. Make sure bathers know where it is and how to use it in case of emergency. To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
• Do not use the pump 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.

• Hazardous Suction. Can trap hair or body, causing severe injury or death.

• Do not block suction.

• Keep small children under close adult supervision at all times.

• Risk of suction entrapment. Always turn off all power to the pool pump before installing the cover or working on any suction outlet.

• This pump produces high levels of suction and creates a strong vacuum at the main drain at the bottom of your pool or spa. This suction is so strong that it can trap adults or children underwater if they come in close proximity to a pool or spa drain or a loose or broken drain cover or grate.

• Stay off the main drain and away from all suction outlets!

• Risk of suction entrapment. The use of unapproved covers or allowing use of the pool or spa when covers are missing, cracked, or broken can result in body or limb entrapment, hair entanglement, body entrapment, evisceration, and/or death.

• The suction at a pool or spa drain or outlet can cause:

• Limb Entrapment: When a limb is sucked or inserted into an opening resulting in a mechanical bind or swelling. This hazard is present when a drain cover is missing, broken, loose, cracked or not properly secured.

• Hair Entanglement: When the hair tangles or knots in the drain cover, trapping the swimmer underwater. This hazard is present when the flow rating of the cover is too small for the pump or pumps.

• Body Entrapment: When a portion of the body is held against the drain cover trapping the swimmer underwater. This hazard is present when the drain cover is missing, broken or the cover flow rating is not high enough for the pump or pumps.

• Evisceration/Disembowelment: When a person sits on an open pool (particularly a child wading pool) or spa outlet and suction is applied directly to the intestines, causing severe intestinal damage. This hazard is present when the drain cover is missing, loose, cracked, or not properly secured.

• Mechanical Entrapment: When jewelry, swimsuit, hair decorations, finger, toe or knuckle is caught in
  an opening of an outlet or drain cover. This hazard is present when the drain cover is missing, broken, loose, cracked, or not properly secured.

• NOTICE all suction plumbing must be installed in accordance with the latest national and local codes for swimming pools, spas and hot tubs, including nspi standards and CPSC guidelines.

WARNING: To minimize the risk of injury due to suction entrapment hazard

• Pools and spas should utilize a minimum of two drains per pump.
• A properly installed and secured ANSI/ASME A112.19.8 approved anti-entrapment suction cover must be used for each drain.
• Each suction cover must be installed at least three (3’) feet apart, as measured from the nearest point to nearest point.
• Regularly inspect all covers for cracks, damage and advanced weathering.
• If a cover becomes loose, cracked, damaged, broken or is missing, close the pool or spa immediately, shut off the pump, post a notice and keep the pool or spa closed until an appropriate certified cover is properly installed.
• Replace drain covers as necessary. Drain covers deteriorate over time due to exposure to sunlight, pool chemicals and weather.
• Avoid getting hair, limbs or body in close proximity to any suction cover, pool drain or outlet.
• Disable suction outlets or reconfigure into return inlets.
• Risk of harm. A clearly labeled emergency shut-off switch for the pool pump and spa jet pump must be in an easily accessible, obvious place near the pool or spa. Make sure bathers know where it is and how to use it in case of emergency.
• Risk of harm. To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
• Risk of electric shock. Can shock, burn or kill. Connect only to a branch circuit protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot verify that the circuit is protected by a GFCI. This unit must be connected only to a supply circuit that is protected by a ground-fault circuit-interrupter (GFCI). Such a GFCI should be provided by the installer and should be tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to the pump without the test button being pushed, a ground current is flowing, indicating the possibility of an electric shock. Do not use this pump. Disconnect the pump and have the problem corrected by a qualified service representative before using.
• 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.
• Risk of hazardous pressure. Pool and spa circulation systems operate under high pressure. Incorrectly installed or tested equipment may fail, causing severe injury or property damage. Read and follow instructions in owner’s manual when installing and operating equipment. Have a trained pool professional perform all pressure tests.

1. Do not connect system to a high pressure or city water system.
2. Use equipment only in a pool or spa installation.
3. Trapped air in system can cause explosion. BE SURE all air is out of system before operating or testing equipment. See hazardous pressure warning below. Do not use compressed air to clean, test, or purge equipment for winter.

Before pressure testing, make the following safety checks:

• Check all clamps, bolts, lids, and system accessories before testing.
• Release all air in system before testing.
• Tighten pump trap lids to 30 ft. lbs. (4.1 kg-m) torque for testing.
• Water pressure for test must be less than 25 PSI (7.5 kg/cm²).
• Water temperature for test must be less than 100° F (38° C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready for operation. Remove trap lid and retighten hand tight only.
• NOTICE These testing parameters apply only to the models described herein. For other equipment, consult the manufacturer.
• Risk of hazardous pressure. Stand clear of pump and filter during start-up. Pool and spa circulation systems operate under high pressure. When any part of the circulating system (i.e. locking ring, pump, filter, valves, etc.) is serviced, air can enter the system and become pressurized.
• Pressurized air can cause the pump housing cover filter lid and valves to violently separate which can result in severe personal injury or death.
• Filter tank lid and strainer cover must be properly secured to prevent violent separation.
• Stand clear of all circulation system equipment when turning on or starting up pump.
• Before servicing pool and spa equipment, make note of the filter pressure. Be sure that all controls are set to ensure the system cannot inadvertently start during service. Turn off all power to the pump.
• Place filter manual air relief valve in the open position and wait for all pressure in the system to be relieved.
• Before starting the system, fully open the manual air relief valve and place all system valves in the “open” position to allow water to flow freely from the pool and spa back to the pool or spa. Stand clear of all pool and spa equipment and start the pump.
• Do not close filter manual air relief valve until all pressure has been discharged from the valve and a steady stream of water appears. Observe filter pressure gauge and be sure it is not higher than the pre-service condition.
• Warnings and safety instructions for these pumps are available at: http://www.pentairpool.com/pool-owner/safety-warnings/ or call 800-831-7133 for additional free copies of these instructions.

General Warnings

• All work must be performed by a qualified pool professional, and must conform to all national, state, and local codes.

• Install to provide drainage of compartment for electrical components.

• 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.

• Risk of harm. 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.

• Electrical controls such as on/off switches, timers, and control systems, etc. should be properly installed to allow the operation (start-up, shut-down, or servicing) of any pump or filter without requiring the user to place any portion of his/her body over or near the pump strainer lid or filter lid. Such installation should allow the user to stand clear of the filter and pump during system start-up, shut down or servicing of the system.

• Hazardous voltage. Capacitor voltage may be hazardous. To discharge motor capacitor, hold insulated handle screwdriver BY THE HANDLE and short capacitor terminals together. Do not touch metal screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.

• The pump is not submersible.

• The pump is designed for use with chlorinated pools only. For use with other applications, contact customer service.

Installation

• NOTICE Port threads are: Internal – 2” NPT for direct connection to pipe. External – 3-1/4” Buttress.
• For quick disconnect pipe connections, use the 1-1/2” Slip Half Union Kit included with the pump.
• Only qualified, licensed personnel should install pump and wiring.

Pump mount must:

• Be located away from corrosive or flammable liquids.
• Have enough ventilation to maintain air temperature at less than the maximum ambient temperature rating (Max. Amb.) listed on the motor model plate. If this pump is installed in an enclosure/pump house, the enclosure must have adequate ventilation and air circulation to keep the temperature in the enclosure at or below the motor’s rated ambient temperature whenever the pump is running.
• Be solid – Level – Rigid – Vibration free. (To reduce vibration and pipe stress, bolt pump to mount.)
• Allow pump suction inlet height to be as close to water level as possible. Pump will not lift water more than 10’(3m).
• Allow use of short, direct suction pipe (To reduce friction losses).
• Allow for gate valves in suction and discharge piping.
• Have adequate floor drainage to prevent flooding.
• Be protected from excess moisture.
• Allow adequate access for servicing pump and piping.
• Risk of fire and burns. Can cause severe injury, property damage or death. Motors run at high temperatures. To reduce the risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. To avoid burns when handling the motor, let it cool for 20 minutes before trying to work on it.
• NOTICE When connecting threaded pipe directly to pump, use PTFE pipe thread sealant tape to seal connections. Do not use pipe dope because it causes cracking in some plastics and may damage components in piping system.
• When connecting pipe to pump with union half, use PTFE tape between pipe and union adapter. Union collar to pump should be assembled dry and hand-tight.
• NOTICE Pump suction and discharge connections have molded in thread stops. DO NOT try to screw pipe in beyond these stops.

Thread sealant tape instructions:

• Use only new or clean PVC pipe fittings.
• Wrap male pipe threads with one to two layers of PTFE tape. Cover entire threaded portion of pipe.
• Do not overtighten or tighten past thread stop in pump port!
• If leaks occur, remove pipe, clean off old tape, rewrap with one to two additional layers of tape and remake the connection.
• NOTICE Support all piping connected to pump!

Piping

• Use at least 1-1/2” (38mm) pipe (use 2”(51mm) pipe if possible). Increase size if a long run is needed. When using 1-1/2” pipe, connect to pump with 1-1/2” to 2”
  (38 to 51mm) reducing adapter (included).

• To avoid strains on the pump, support both suction and discharge pipes independently. Place these supports near the pump.

• To avoid a strain left by a gap at the last connection, start all piping at the pump and run pipe away from the pump.

• To avoid airlocking, slope suction pipe slightly upward toward the pump.

• NOTICE To prevent flooding when removing pump  for service, all flooded suction systems must have gate valves in suction and discharge pipes.

Pool Pump Suction Requirements

• Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or operate swimming pools, spas, or hot tubs if a suction outlet cover is missing, broken, or loose. Follow the guidelines below for a pump installation which minimizes risk to users of pools, spas, and hot tubs.

Entrapment Protection

• The pump suction system must provide protection against the hazard of suction entrapment or hair entrapment/entanglement.

Suction Outlet Covers

• All suction outlet covers must be maintained. They must be replaced if cracked, broken, or missing.
• See Testing and Certification for outlet cover certification requirements.
• All suction outlets must have correctly installed, screw-fastened covers in place.

Suction Outlets Per Pump

• Provide at least two hydraulically balanced main drains, with covers, as suction outlets for each circulating pump suction line (see Figure 2). The centers of the main drains (suction outlets) on any one suction line must be at least three feet apart.

• The system must be built so that it cannot operate
  with the pump drawing water from only one main drain (that is, there must be at least two main drains connected to the pump whenever it is running – see Figure 2).

• However, if two main drains run into a single suction line, the single suction line may be equipped with a valve which will shut off both main drains from the pump.

• More than one pump can be connected to a single suction line as long as the requirements listed above are met.

Water Velocity

• The maximum water velocity through the suction
  fitting or cover for any suction outlet must be 1.5 feet per second unless the outlet complies with the latest ASME/ANSI Specification for Suction Fittings For Use in

• Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any case, do not exceed the suction fitting’s maximum designed flow rate.

• If 100% of the pump’s flow comes from the main drain system, the maximum water velocity in the pump suction hydraulic system must be six feet per second or less even if one main drain (suction outlet) is completely blocked. The flow through the remaining main drain(s) must comply with the latest ASME/ANSI Specification for Suction

• Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.

Testing and Certification

• Suction outlet covers must have been tested by a nationally recognized testing laboratory and found to comply with the latest ASME/ANSI Specifications for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.

Installation  Electrical.

Fittings

• Fittings restrict flow; for best efficiency use fewest possible fittings (but at least two suction outlets).
• Avoid fittings which could cause an air trap.
• Pool fittings must conform to International Association of Plumbing and Mechanical Officials (IAPMO) standards. Use only non-entrapping suction fitting or
  double suction.

Electrical

• Risk of electric shock. Can shock, burn or kill. Ground pump before connecting to power supply.
• Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal electrical shock hazard.
• To avoid dangerous or fatal electrical shock, turn OFF power to motor before working on electrical connections.
• Ground Fault Circuit Interrupter (GFCI) tripping indicates an electrical problem. If GFCI trips and will not reset, have a qualified electrician inspect and repair electrical system.
• Exactly match supply voltage to nameplate voltage. Incorrect voltage can cause fire or seriously damage motor and voids warranty. If in doubt consult a licensed electrician.
• WARNING Risk of explosion. Do not ground to a gas supply line.

Voltage

• Voltage at motor must be not more than 10% above or below motor nameplate rated voltage or motor may overheat, causing overload tripping and reduced component life. If voltage is less than 90% or more than 110% of rated voltage when motor is running at full load, consult power company.

Grounding/Bonding

• Install, ground, bond and wire motor according to local or National Electrical Code requirements.
• Permanently ground motor. Use green ground terminal provided under motor canopy or access plate (See Figure 3); use size and type wire required by code. Connect motor ground terminal to electrical service ground.
• Connect a No. 8 AWG (8.4 sq.mm) solid copper bonding wire to the bonding lug provided on the motor housing and to all metal parts of the swimming pool, spa, or
  hot tub and to all electrical equipment, metal piping or conduit within 5 feet (1.5 m) of the inside walls of swimming pool, spa, or hot tub.

To Wire a Dual Voltage Motor

• Dual voltage motors have a plug to change from 230 Volts (factory setting) to 115 Volts.

1. If you have 230 Volt motor supply voltage, confirm that the plug is set for 230 Volts. The arrow on the plug will point to the 230 Volt position. Note that plug only connects with one prong in this position.
2. If you have 115 Volt supply, pull the plug straight up and place it on the two brass prongs as shown.
3. Some motors may use a knob to select voltage:

Electrical

Wiring

• Pump must be permanently connected to circuit. Table I gives correct wire and circuit breaker sizes for the pump alone. If other lights or appliances are also on the same circuit, be sure to add their amp loads to pump amp load before figuring wire and circuit breaker sizes. (If unsure how to do this or if this is confusing, consult a licensed electrician.) Use the load circuit breaker as the master on-off switch.
• Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-circuit to ground and disconnect power before it becomes dangerous to pool users. For size of GFCI required and test procedures, see GFCI manufacturer’s instruction.
• In case of power outage, check GFCI for tripping (which will prevent normal pump operation). Reset if necessary.
• NOTICE If you do not use conduit when wiring motor, be sure to seal wire opening on end of motor to prevent dirt, bugs, etc., from entering.

Operation Storage

• NOTICE NEVER run pump dry. Running pump dry may damage seals, causing leakage and flooding. Fill the pump with water before starting the motor.
• Risk of explosion. Before removing trap cover:

1. Stop pump before proceeding.
2. Close gate valves in suction and discharge pipes.
3. Release all pressure from pump and piping system.
4. If pump is being pressure tested, be sure pressure has been released before removing trap cover.

• Risk of fire and burns. Motors run at high temperatures. To reduce the risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. To avoid burns when handling the motor, let it cool for 20 minutes before trying to work on it. An automatic internal cutoff switch protects the motor from heat damage during operation.
• Hazardous Suction. Can trap hair or body, causing severe injury or death.
• Do not block suction.
• Keep small children under close adult supervision at all times.

Priming Pump

• Release all pressure from filter, pump, and piping system; see the filter owner’s manual.
• In a flooded suction system (water source higher than pump), pump will prime itself when suction and discharge valves are opened.
• If pump is not in a flooded suction system, unscrew and remove trap cover; fill trap and pump with water. Do not lubricate the trap cover O-ring. The original equipment O-ring contains a permanent internal lubricant.
• NOTICE If you replace the O-ring with a non-internally lubricated O-ring, you may need to apply a silicone based lubricant. Clean and inspect O-ring; reinstall on trap cover.
• Replace trap cover on trap; turn clockwise to tighten cover.
• NOTICE Tighten trap cover by hand only (no wrenches)!Pump should prime now. Priming time will depend on vertical length of suction lift and horizontal length of suction piping.
• If pump does not prime within three minutes, make sure that all valves are open, suction pipe end is under water, pump is not trying to lift water more than 10’ (3m), and that there are no leaks in suction pipe. If necessary, see Troubleshooting.

Storage/Winterizing:

• NOTICE Allowing pump to freeze will damage pump and void warranty!
• NOTICE Do not use anti-freeze solutions (except propylene glycol) in your pool/spa system. Propylene glycol, or “RV antifreeze”, is non-toxic and will not damage plastic system components; other anti-freeze formulas are highly toxic and may damage plastic components in the system.
• Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time (see Draining Pump).
• Keep motor dry and covered during storage.
• To avoid condensation/corrosion problems, do not cover the pump with plastic.

For outdoor/unprotected installations:

1. Enclose the entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow ventilation; do not wrap the system in plastic.
3. Use a 40% propylene glycol/60% water solution to protect the pump to -50°F (-46°C).

Draining Pump

• Risk of electric shock. Can shock, burn or kill. Disconnect power before working on the pump or motor.

1. Pump down water level below all inlets to the pool. Risk of electric shock. Can shock, burn or kill. To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining pump.

2. Remove trap cover and use low pressure air to blow accumulated water from the piping system. Never use high pressure air to purge system.

3. Cap inlet piping after draining to keep water out of the pipes.

4. To prevent pump from freezing, remove trap cover and drain the tank body through the two drain plugs provided. Clean pump thoroughly; replace trap cover.
   NOTICE Tighten trap cover by hand only (no wrenches)! If pump is not anchored, use caution to avoid breaking attached piping!

5. Be sure motor is kept dry and covered.

Storage Maintenance

Startup For Winterized Equipment

1. Remove any temporary weather protection placed around system for shutdown.
2. Follow filter manufacturer’s instructions for reactivation of the filter.
3. Inspect all electrical wiring for damage or deterioration over the shutdown period. Have a qualified serviceman repair wiring as needed.

9. Place seal plate face down on flat surface and tap out ceramic seat (Figure 5).
10. Remove slinger from motor shaft and inspect for damage or abrasion.
11. Clean seal cavity in seal plate and clean motor shaft.

Pump Reassembly/Installing New Seal

1. Ceramic seat must be clean and free of dirt, grease, dust, etc. Wet outer edge with small amount of liquid detergent; press ceramic seat into seal plate cavity firmly and squarely with finger pressure (Figure 6).

Troubleshooting

1. If ceramic seat will not locate properly, remove it, place face up on bench and reclean cavity. Ceramic seat should now locate.

2. If seat still will not locate properly, place a cardboard washer over the polished face and use a piece of 3/4” (19mm) standard pipe for pressing purposes. NOTICE Be sure not to scratch or mar polished surface or seal will leak.

3. Replace slinger on end of motor shaft so that impeller sleeve will push it into position. If slinger shows signs of wear or damage, replace it.

4. Remount seal plate on motor. Tighten bolts to 60- 80 inch-lbs. (69-92 kg/cm) torque.

5. Apply a small amount of liquid detergent to inside diameter of rotating half of seal.

6. Slide rotating seal member, polished carbon face out, over impeller sleeve until rubber drive ring hits back of impeller.
   NOTICE Be sure not to nick or scratch polished seal face; seal will leak if face is damaged.

7. Screw impeller onto shaft (clockwise); this will automatically locate seal in seal plate.

8. Mount diffuser on seal plate; tighten screws to

9. 14 inch-lbs. (11.2-16.1 kg/cm) torque.

10. Assemble motor and seal plate to pump body with nuts, flat washers and lock washers. Torque nuts to 120- 130 in-lbs. (138-150 kg/cm).

Warranty

Retain Original Receipt For Warranty Eligibility

Limited Warranty

• This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011. FLOTEC warrants to the original consumer purchaser (“Purchaser” or “You”) that its products are free from defects in material and workmanship for a period of twelve (12) months from the date of the original consumer purchase. If, within twelve (12) months from the original consumer purchase, any such product shall prove to be defective, it shall be repaired or replaced at FLOTEC’s option, subject to the terms and conditions set forth herein. Note that this limited warranty applies to manufacturing defects only and not to ordinary wear and tear. All mechanical devices need periodic parts and service to perform well. This limited warranty does not cover repair when normal use has exhausted the life of a part or the equipment.

• The original purchase receipt and product warranty information label are required to determine warranty eligibility. Eligibility
  is based on purchase date of original product – not the date of replacement under warranty. The warranty is limited to repair or replacement of original purchased product only, not replacement product (i.e. one warranty replacement allowed per purchase). Purchaser pays all removal, installation, labor, shipping, and incidental charges.

• For parts or troubleshooting assistance, DO NOT return product to your retail store – contact FLOTEC Customer Service at
  1-800-365-6832.

• Claims made under this warranty shall be made by returning the product (except sewage pumps, see below) to the retail outlet where it was purchased or to the factory immediately after the discovery of any alleged defect. FLOTEC will subsequently take corrective action as promptly as reasonably possible. No requests for service will be accepted if received more than 30 days after the warranty expires. Warranty is not transferable and does not apply to products used in commercial/rental applications.

Sewage Pumps

• DO NOT return a sewage pump (that has been installed) to your retail store. Contact FLOTEC Customer Service. Sewage pumps that have seen service and been removed carry a contamination hazard with them.

If your sewage pump has failed:

• Wear rubber gloves when handling the pump;
• For warranty purposes, return the pump’s cord tag and original receipt of purchase to the retail store;
• Dispose of the pump according to local disposal ordinances.

General Terms and Conditions; Limitation of Remedies

• You must pay all labor and shipping charges necessary to replace product covered by this warranty. This warranty does not apply to the following: (1) acts of God; (2) products which, in FLOTEC’s sole judgment, have been subject to negligence, abuse, accident, misapplication, tampering, or alteration; (3) failures due to improper installation, operation, maintenance or storage; (4) atypical or unapproved application, use or service; (5) failures caused by corrosion, rust or other foreign materials in the system, or operation at pressures in excess of recommended maximums.
• This warranty sets forth FLOTEC’s sole obligation and purchaser’s exclusive remedy for defective products.
• FLOTEC SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER. THE FOREGOING LIMITED WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE FOREGOING LIMITED WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION PROVIDED HEREIN.
• Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on how long an implied warranty lasts, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and You may also have other rights which vary from state to state.
