DANGER

HAZARDS RELATED TO SUCTION ENTRAPMENT: stay away from all suction outlets and the main drain!

in addition, this pump is not equipped with safety vacuum release system

(SVRS) protection. in order to prevent accidents, please prevent your body

or hair from being sucked by the water pump inlet.

At the main water line, the pump produces a strong vacuum and a high level of suction. Adults and children can be trapped underwater if they are near drains, loose or broken drain covers or grates. A swimming pool or spa covered with non-approved materials or one with a missing, cracked, or broken cover can cause limb entrapment, hair entanglement, body entrapment, evisceration, and/or death.

There are several causes of suction at drains and outlets:

Limb Entrapment: A mechanical bind or swelling occurs when a limb is sucked into an opening. Whenever there is a problem with a drain cover, such as a broken, loose, cracked or improperly fastened one, this hazard occurs. Hair Entanglement: The tangle or knotting of the swimmer’s hair in the drain cover, resulting in the swimmer being trapped underwater. When the flow rating of the cover is too low for the pump or pumps, this hazard may arise. Body Entrapment: When a portion of the swimmer’s body is trapped under the drain cover. When the drain cover is damaged, missing, or not rated for the pump, this hazard arises. Evisceration/Disembowelment: A suction from an open pool (usually a child’s wading pool) or spa outlet causes severe intestinal damage to a person. 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. If the drain cover is missing, broken, loose, cracked, or not properly secured, this hazard exists.
NOTE: THE PLUMBING FOR SUCTION MUST BE INSTALLED IN ACCORDANCE WITH THE LATEST LOCAL AND NATIONAL CODES.

WARNING

IN ORDER TO REDUCE INJURY RISKS FROM SUCTION ENTRAPMENT HAZARDS:

· Each drain must be equipped with an ANSI/ASME A112.19.8

approved anti-entrapment suction cover.

· Each suction cover should be installed minimum three (3′) feet

apart measuring between the closest points.

· Check all covers for cracks, damage, and advanced weathering

regularly.

· Replace a cover if it becomes loose, cracked, damaged, broken,

or missing.

· Replace drain covers as necessary. Drain covers deteriorate

over time due to exposure to sunlight and weather.

· Avoid getting close to any suction cover, pool drain, or outlet with

your hair, limbs, or body.

· Suction outlets can be disabled or reset into return inlets

IMPORTANT WARNING AND SAFETY INSTRUCTIONS

WARNING

A high level of suction can be generated by the pump in the plumbing system’s suction side. The high

level of suction can pose a threat to those in close proximity to the suction

openings. This high vacuum can cause serious injuries or cause people to

become trapped and drown. Swimming pool suction plumbing must be

installed according to the latest national and local codes.

WARNING

A clearly identified emergency shut-off switch for the pump should be located in a highly visible location.

Ensure that all users know where it is located and how to use it in case of

an emergency.

The Virginia Graeme Baker (VGB) Pool and Spa Safety Act establishes new requirements for commercial swimming pool and spas owners and
operators.

On or after December 19, 2008, commercial pools and spas must use: A multiple main drain system without isolation capability with suction outlet covers complying with ASME/ANSI A112.19.8a Suction Fittings for Swimming Pools, Wading Pools, Spas, and Hot Tubs and either: (1) Safety vacuum release systems (SVRS) that meet ASME/ANSI A112.19.17 Manufactured Safety Vacuum Release systems (SVRS) for Residential and Commercial Swimming Pools, Spas, Hot Tubs, and Wading Pool Suction Systems, or ASTM F2387 Standard Specification for Manufactured Safety Vacuum Release Systems (SVRS) for Swimming Pools, Spas and Hot Tubs (2) Suction-limiting vents that have been properly designed and tested (3) System for shutting off pumps automatically

Information about Installation: · There is a requirement that all work be performed by a qualified service professional and in accordance with all national, state, and local regulations. · Ensure that electrical components are properly drained in the compartment. · There are several models of pump included in these instructions, so some may not apply to a specific model. All models are geared toward swimming pool use. If the pump is properly sized for the specific application and properly installed, it will function correctly.

WARNING

The improper size, installation, or use of pumps in applications for which they were not designed can

result in serious personal injury or death. There are a number of risks

involved, including electric shocks, fires, flooding, suction entrapment,

severe injury to others or property damage as a result of structural failures

in pumps or other system components.

Pumps and replacement motors that are single speed and one (1) Total HP or greater cannot be sold, offered for sale, or installed in a residential pool for filtration use in California, Title 20 CCR sections 1601-1609.

Pools and spas constructed before December 19, 2008, with a single submerged suction outlet, must use a suction outlet cover that meets ASME/ANSI A112.19.8a or either: (A) A SVRS compatible to ASME/ANSI A112.19.17 and/or ASTM F2387,or (B) Suction-limiting vents that have been properly designed and tested or (C) System for shutting off pumps automatically, or (D) Submerged outlets can be disabled or (E) Reconfiguration of suction outlets into return inlets is required.

CAUTION

Installing electrical controls at the equipment pad (ON/OFF switches, timers, and automation load

centers)

Ensure that all electrical controls are installed at the equipment pad,

including switches, timers, and control systems. To prevent the user from

putting his/her body over or near a pump strainer lid, filter lid, or valve

closure when starting, shutting down, or servicing a pump or filter.

During system start-up, shutdown, or servicing of the filter, the user should

be able to stand far enough away from the filter and pump.

DANGER

When starting up, keep the filter and pump away from your body.

When parts of a circulating system are serviced (i.e. locking rings, pumps,

filters, valves, etc.) air can enter and pressurize the system. It is possible

for the pump housing cover, filter lid, and valves to violently separate when

subjected to pressurized air. You must secure the strainer cover and filter

tank lid to prevent violent separation.

When turning on or starting up the pump, keep all circulation equipment

clear of you. You should note the filter pressure before servicing the

equipment. Make sure that the pump controls are set so that it cannot start

inadvertently during service.

IMPORTANT: Ensure that the filter manual air relief valve is in the open position and wait for all pressure in the system to be released. Open the manual air relief valve fully and put all system valves in the “open” position before starting the system. Make sure you stand clear of any equipment when starting the system. IMPORTANT: If the filter pressure gauge is higher than the pre-service condition, don’t close the manual air relief valve until all pressure has been released from the valve and a steady stream of water appears.

INSTALLATION

INSTALLATION:
It is essential to only use a qualified professional to ensure a safe and successful installation. Failure to follow this instructions correctly could result in serious injury or property damage.
LOCATION:
NOTE: It is important to note that when installing this pump, it should not be placed within an outer enclosure or underneath the skirt of a hot tub or spa, unless it is marked accordingly. Note: it is essential to ensure that the pump is mechanically secured to the equipment pad for proper functioning.
Make sure the pump can match the below requirements: 1. It is important to install the pump as close to the pool or spa as possible.
This will reduce friction loss and improve the overall efficiency of the pump. To further reduce friction loss and improve efficiency, it is recom mended to use short, direct suction and return piping. 2. It is important to ensure that there is a minimum of 5′ (1.5 m) between the inside wall of the pool and spa and any other structures. For any Canadian installations, a minimum of 9.8′ (3 m) from the inside wall of the pool must be maintained. 3. It is important to install the pump at least 3′ (0.9 m) away from the heater outlet. 4. It is important to remember to not install the self-priming pump more than 8′ (2.6 m) above the water level. 5. it is important to choose a well-ventilated location that is protected from excess moisture. 6. Please keep at least 3″ from rear of motor and 6″ from the top of control pad for easy maintenance and repair.

Fittings and Valves:
1. 90° elbows directly into pump intake & discharge are NOT allowed. 2. Installing gate valves on suction and discharge pipes is an important
part of any flooded suction system, as it allows for maintenance and other activities to be carried out more easily. However, the suction gate valve should not be placed any closer than five times the diameter of the suction pipe. 3. Using a check valve in the discharge line is highly recommended for any application of this pump where there is significant plumbing height after the pump. 4. It is important to install check valves when plumbing in parallel with another pump to ensure proper functioning. Check valves help to prevent reverse rotation of the impeller and motor.

Electrical Installation:

DANGER

READ THIS INSTRUCTION BEFORE OPERATION RISK OF ELECTRICAL SHOCK OR ELECTROCU-

TION.

It is essential that the pump MUST be installed by a qualified and licensed

electrician, or a certified service professional, in accordance with the

National Electrical Code and all applicable local codes and ordinances.

When the pump is not properly installed, it can create an electrical hazard,

which can potentially lead to death or serious injury, due to electric shock

or electrocution.

It is essential to always disconnect power to the pump at the circuit breaker before servicing the pump. Failing to do so can have catastrophic consequences for those involved: Electric shock and property damage are the least of the dangers; Death or serious injury to service people, pool users, or even bystanders can occur.

6 Inches(15.2cm) Minimum

The pump can automatically accept a single phase, 115/208-230V, 50 or 60 Hz input power and No wiring change is required. The power connections (below picture) are capable of handling up to 10 AWG solid or stranded wire.

3 Inches (7.62cm) Minimum

PIPING:
1. The Piping diameter on the intake of the pump should be the same or larger than the one of the discharge.
2. The shorter of plumbing on the suction side is better. 3. A valve on both suction and discharge lines is recommended for easy
maintenance and repair. 4. Any valve, elbow or tee installed in the suction line should be at least five
(5) times of suction line diameter from the discharge port. For example, 2″ pipe requires 10″ straight line before the suction port of the pump, as below drawing.

5 times of suction line diameter

Check before the initial startup – Check that the shaft turns freely. – Check whether the power supply voltage and frequency are consistent with the nameplate. – Check for obstructions in the pipe. – A system should be configured to prevent the pump from starting when there is no minimum water level. – Check the rotation direction of the motor, it should be consistent with the indication on the fan cover. If the motor won’t start, try to find the problem in the table of most common faults and see possible solutions.
Start Open all gates and power on the motor, check the circuit breaker current of the motor, and adjust the overheat protector appropriately. Apply voltage to the motor and adjust the nozzle properly to obtain the desired flow.
Turn on the power, the POWER indicator light is on, and the inverter is in the stop state. The system time and icon are displayed on the LCD screen. Press the key, the water pump starts or stands by, and runs at a speed of 3450r/min for 10 minutes each time it starts (Note 1). At this time, the LCD screen displays the system time, icon, running icon, SPEED 4, 3450RPM and countdown of primg time; after 10 minutes of running , work according to the preset automatic mode (the system time,
icon, running icon, rotating speed, start and stop running time, multi-stage speed number are displayed on the screen), and the multi-stage speed is executed sequentially in chronological order (there are multiple-stage speed settings in the same time period) , the running priority is: > > ), if there is no need for a multiple-stage speed, it is necessary to set the start and end time of the multiple-stage speed to be the same.

Priorities Note: In the case of a pump that is installed below the water line of a pool, ensure that the return and suction lines are closed before opening the
strainer pot on the pump. Before operating, reopen valves.

MAINTENANCE

ALARM: It is important to be aware that if the pump fails to prime or has been operating without water in the strainer pot, it should not be opened. This is because the pump may contain a build up of vapor pressure and scalding hot water, which could result in serious personal injury if opened. To ensure safety and avoid potential personal injury, all suction and discharge valves must be opened carefully. Additionally, you should verify that the strainer pot temperature is cool to the touch before proceeding to open the valves with extreme caution.
ATTENTION: To ensure that the pump and system remain in optimal working condition, it is important to clean the pump strainer and skimmer baskets regularly.
ALARM: Before servicing the pump, turn off the circuit breaker. Electric shock could kill or seriously injure service workers, users, or others if this is not done. Before servicing the pump, read all servicing instructions.
Cleaning the pump strainer & skimmer basket:
It is highly recommended to check the Strainer Basket as frequently as possible to clean up the trash. The safety instruction is as follows: 1. Press Stop/ Start to stop the pump. 2. Turn off power to the pump at the circuit breaker. 3. In order to relieve all pressure from the filtration system, the filter air
relief valve must be activated. 4. To remove the strainer pot lid, twist it in a counterclockwise direction. 5. Take the strainer basket out from the strainer pot. 6. Clean up the trash from Basket. Note: If there is any cracks or damage on the basket, replace it with a new one. 7. Carefully lower the basket into the strainer pot, making sure that the notch in the bottom of the basket is aligned with the rib on the bottom of the pot. 8. The strainer pot should be filled with water up to the inlet port. 9. The lid, O-ring and sealing surface should be Cleaned carefully. Note: Keeping the lid O-ring clean and well lubricated is essential to maintain the life and performance of the pump. 10. Install the lid onto the strainer pot and turn the lid clockwise in order to
lock it securely into place. Note: In order to properly lock the lid, the handles need to be nearly perpendicular to the pump body. 11. Turn on power to the pump at the circuit breaker. 12. Open the filter air relief valve 13. Keep away from the filter and turn on the pump. 14. To bleed air from the filter air relief valve, open the valve and let the air
escape until a steady stream of water appears.

DANGER

All parts of circulation system (Lock Ring, Pump, Filter, Valves, and so on) are running under high

pressure. Pressurized air can be a potential hazard because it can cause

the lid to be exploded off, potentially resulting in serious injury, death, or

property damage. In order to avoid this potential hazard, please follow

above safety instructions.

Winterizing:
It is important to note that freeze damage is not covered under warranty. If freezing temperatures are predicted, there are steps you can take to reduce the risk of freeze damage. 1. Press Stop/ Start to stop the pump. 2. Turn off power to the pump at the circuit breaker. 3. In order to relieve all pressure from the filtration system, the filter air
relief valve must be activated. 4. Carefully unscrew two drain plugs from the bottom of the strainer pot,
and allow the water to drain completely. Place the drain plugs in the strainer basket for storage. 5. It is important to cover your motor when exposed to extreme weather conditions, such as heavy rain, snow and ice. Note: Wrapping the motor with plastic or any other airtight material is prohibited. When the motor is in use, or when it is expected to be in use, MUST NOT cover the motor. Note: In mild climate areas, it is recommended to run the equipment all night when freezing temperatures are forecast or have already occurred.

Pump care:
Avoid Over-heating 1. Shield from sun & heat 2. Well ventilated environment to avoid over-heating
Avoid messy working conditions 1. Keep working conditions as clean as possible. 2. Keep chemicals away from motor. 3. Dust should not be stirred up or swept near the motor during operation. 4. Dirt damage to the motor may void the warranty. 5. It is important to clean the lid, the O-ring, and the sealing surface of the
strainer pot.
Keep away from moisture 1. Splashing or sprayed water should be avoided. 2. Flood protection from extreme weather. 3. Ensure that the pump is protected from extreme weather conditions
such as flooding. 4. Let the motor internals dry before operating if they have become wet. 5. Flooded pumps should not be operated. 6. Water damage to a motor may void the warranty.
