Important Safety Instructions

⚠️ WARNING: READ THIS MANUAL BEFORE INSTALLING AND OPERATING SHARKJET PUMP. IT INCLUDES IMPORTANT INFORMATION ABOUT SAFE USE OF THIS PRODUCT.

Before installation, read all instructions and warnings carefully. Refer to product dataplate(s) for additional operation instructions and specifications.

When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:

⚠️ RISK OF SUCTION ENTRAPMENT HAZARD WHICH, IF NOT AVOIDED, MAY RESULT IN SERIOUS INJURY OR DEATH.

Pumps can quickly generate high suction, posing an entrapment risk if improperly connected to suction outlets. Disembowelment, entrapment, or drowning is possible when body parts or hair contact damaged, cracked, missing, or unsecured drain covers and suction outlets. Pumps and fittings shall be installed in accordance with the latest NSPI or IAF standards, CPSC guidelines, and national, state, and local codes to minimize this risk. Always consult the latest regulations to ensure your installation meets necessary requirements.

1. All fully submerged Suction Outlet Covers shall be listed to ANSI/ASME A112.19.8 standard.
2. Do not use a pump where there is only one fully submerged single suction outlet.
3. If main drains are installed, there must be a minimum of two for each pumping system, each with a Listed Suction Outlet Cover. Wading pools may have additional requirements.
4. Skimmers may supply 100% of the required flow and must be vented to atmosphere. A skimmer is not a second main drain.
5. When two suction outlets are used, the maximum system flow rate shall not exceed the rating of any one listed suction outlet cover. When more than two are used, the sum of ratings shall be at least twice the maximum system flow rate.
6. Each Suction Outlet Cover shall be separated by a minimum of three feet (3'), measured from center of suction pipes.
7. Avoid installing check valves. If necessary, ensure installation conforms to applicable standards.
8. Never use the pool or spa if a Suction Outlet Cover is damaged, cracked, missing, or not securely attached. Use stainless steel screws supplied with the cover. Order replacements if screws are lost.

⚠️ WARNING:

To reduce risk of injury, do not permit children to use this product unless they are closely supervised at all times.

⚠️ WARNING:

(For cord & plug connected units) Risk of Electric Shock. Connect only to a grounding type receptacle protected by a GFCI. Contact a qualified electrician if you cannot verify GFCI protection.

⚠️ WARNING:

(For cord & plug connected units) Do not bury cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers, and other equipment.

⚠️ WARNING:

(For cord & plug connected units) To reduce the risk of electric shock, if the cord is damaged, replace it immediately with the same type of cord available from your dealer. The new cord must be installed by a qualified electrician. Inspect the cord annually.

⚠️ WARNING:

General Information

This is a self-priming pump, capable of raising water through a dry suction line without valves, provided the pump case and strainer body are full of water before starting. A swing check valve in the suction pipe (at or below water level) is recommended if suction lift is over 5 feet (1.5m) or the dry suction line exceeds 10 feet (3.0m). This simplifies initial priming and keeps the suction pipe primed.

The pump is constructed from glass-reinforced thermoplastic mouldings, eliminating corrosion problems and insulating water passages from the electric motor. A closed impeller with a multi-vane diffuser runs with ample clearances to promote long life and prevent seizure from sand. The impeller hub forms an insulating sleeve over the motor shaft and carries the mechanical shaft seal. The shaft seal has a pure-carbon rotating face against a ceramic seat and requires no attention until leakage indicates replacement is necessary.

For easy servicing, the built-in hair and lint strainer has a transparent cover. The motor, bracket, seal, impeller, and diffuser can be withdrawn as a unit by removing four screws, simplifying maintenance and repair.

Installation

Locate the pump as close to the pool as possible, but at least five feet (1.5M) away to prevent children's access (see Warning). Prefer a dry, shaded, and well-ventilated area. If the pump cannot be placed at or below water level, choose the lowest possible position to simplify priming and enhance pressure. Prepare a hard, level surface large enough for the equipment, considering drainage, motor ventilation, access for servicing/winterizing, and equipment protection. Ensure the bearing surface is level and straight to reduce vibrations.

Piping

The pump has male/female sockets for 1-1/2" (38mm) threaded fittings. Keep piping simple, avoiding direct elbows on the pump inlet. Use a straight pipe section for proper water entry. Keep as much of the suction pipe as possible below the pool's water level to reduce priming time. Arrange the pipe to rise continuously toward the pump to prevent air pockets. Support pipes independently to avoid strain on the pump. Install gate valves in the pump suction and pool return lines near the filter system for convenient servicing. The suction gate valve must remain fully open during operation, and its gland must be kept tight to prevent air entry. Keep pipes clean during installation and ensure the suction system is absolutely airtight.

Electrical Connections

Verify the pump nameplate information matches the power supply. Use a competent electrician for wiring installation according to local electrical codes. Every motor requires a fused disconnect switch.

Starting Up and Operation

For 2-speed pumps, start and prime at HIGH SPEED only. Do not switch to LOW SPEED until the pump is working properly. At HIGH SPEED (approx. 3450 rpm), the motor delivers full horsepower for high capacity and pressure, ideal for maximum filtration and high turbidity. Switch to LOW SPEED (approx. 1725 rpm) at other times. High speed is required for backwashing and vacuuming.

If the pump is part of a complete filter system, follow its specific start-up procedure. Otherwise, proceed as follows:

1. Close gate valves in suction and return lines. Remove the hair and lint strainer cover, fill the pump completely with water, and replace the cover.
2. Open gate valves and start the pump. If full flow is not achieved within four or five minutes, switch off power and repeat Step 1. If still not working, check for air leaks at the strainer cover, suction line connections, and valve stem glands before repeating Step 1.
3. After about ten minutes, check pool return fittings for air bubbles. Continuous air flow indicates suction line leaks; locate and correct them immediately.

❗ CAUTION: Never run the pump without water in the pump case, as lack of water can damage the shaft seal.

Controlling the Output

Keep the suction line gate valve fully open during operation. Use a valve in the return line to control output if necessary.

Lubrication

The pump requires no lubrication. Refer to manufacturer's recommendations.

Draining

The pump case has two drain plugs. Ensure suction and return line valves are open for complete pump draining. Other provisions may be needed for draining the filter, heater, and pipe lines.

Maintenance and Cleaning

The pump can be serviced without breaking pipe connections. Close gate valves, switch the ON/OFF switch to OFF, and pull the plug from the receptacle before starting work.

⚠️ WARNING:

During periods when the pump is not in use, and always during servicing, switch the ON/OFF switch to OFF and pull the plug from the receptacle.

NOTE: THE PUMP SHALL BE SERVICED BY QUALIFIED PERSONNEL ONLY.

Motor Specifications

Refer to the manufacturer's specification sticker on the motor.

Cleaning the Strainer Basket

Turn off power. Close suction and return valves. Remove the strainer nut and cover, then lift out the strainer basket. Clean and replace the basket. Clean the o-ring and ensure it is well seated under the clear cover. Place the cover back on the strainer body. Align and insert the strainer nut, hand-tighten only (Fig. 1). Re-open valves and restart the pump.

NOTE: Do not re-tighten the Strainer Nut while the pump is in operation.

Dismantling and Repair

To Dismantle the Pump: IMPORTANT: ENSURE ELECTRICAL POWER IS DISCONNECTED BEFORE CONTINUING. Refer to illustrated steps on Page 5.

Inspection

Inspect all pump parts for wear or damage and order replacements as needed. Carefully check the shaft seal (12) for cracks in the ceramic seat, wear on seal faces, and holes/cracks in rubber parts. Replace the complete seal if any part is damaged or leaks. Do not use old parts.

Shaft Seal Replacement

Handle the shaft seal (12) with care to avoid damaging its carbon and ceramic sealing faces. DO NOT USE OIL OR GREASE ON SEAL PARTS, as this may damage the pump's thermoplastic material through overheating or chemical reaction. Ensure pump parts are clean, but do not scratch surfaces that contact the seal. Moisten the ceramic and rubber housing with water and press firmly by hand into the motor bracket (13). Ensure the ceramic's flat surface faces the pump body. Reassemble the pump following the steps on page 5. Reinstall and run for 5 minutes to check for leaks, which indicate improper seal installation. Repeat if leaks are observed.
