Important Safety Instructions

WARNING: RISK OF SUCTION ENTRAPMENT HAZARD WHICH, IF NOT AVOIDED, MAY RESULT IN SERIOUS INJURY OR DEATH. Pumps can quickly generate high suction, which poses the risk of entrapment 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 that your installation meets the necessary requirements to minimize suction entrapment.

1. All fully submerged Suction Outlet Covers shall be listed to ANSI/ASME A112.19.8 standard.
2. Do not use a pump in an installation where there is only one fully submerged single suction outlet.
3. If main drains are installed in your pool, there must be a minimum of two for each pumping system, and each drain must include a Listed Suction Outlet Cover. Wading pools may have additional requirements to minimize entrapment hazards.
4. Skimmers may supply 100% of the required flow to the pump, and must be vented to atmosphere. A skimmer is not considered a second main drain.
5. When two suction outlets are used, the maximum system flow rate shall not exceed the rating of any one of the listed suction outlet covers installed. When more than two are used, the sum of the 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 check valves must be used, ensure that the 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. Suction outlet cover must be attached with stainless steel screws supplied with the cover. If screws are lost, order replacement parts from your supplier.

General

This is a self-priming pump, which means that it can raise water to itself through a dry suction line without using valves, provided the pump case and strainer body are full of water before the motor is started. Carvin recommends the use of a swing check valve in the suction pipe, at or below water level, if the suction lift is more than 5 feet (1.5m) or if the dry suction line would be more than 10 feet (3.0m) long. This arrangement makes the initial priming easy and keeps the suction pipe primed at all times. The pump is built from glass-reinforced thermoplastic mouldings. These eliminate all corrosion problems and insulate the water passages from the electric motor. A closed impeller, which requires no field adjustment to maintain efficiency, runs inside a multi-vane separate diffuser. Ample running clearances between impeller and case promote long life and prevent seizure should sand enter the pump. The impeller hub forms an insulating sleeve over the motor shaft and carries the mechanical shaft seal. This seal, which has a pure-carbon rotating face working against a ceramic seat, requires no attention until leakage at the shaft shows that replacement is necessary. For easy routine servicing, the built-in hair and lint strainer has a transparent cover. For easy access to the working parts, the removal of six screws allows the motor, bracket, seal, impeller and diffuser to be withdrawn as a unit. Anti-vibration features have been added to the splash cover and base resulting in quiet running. Shark-Wave assemblies were simplified for ease of maintenance and repair.

Installation

Locate the pump as close to the pool as possible, but keep at a minimum distance of at least five feet (1.5M) to prevent it being used as a means of access to the pool by young children (See previous Warning). Locate the pump preferably in a dry, shaded, and well-ventilated area. Should it be impossible to put the pump at or below water level, choose the lowest possible position. This simplifies priming, and adds to the pressure developed by the pump. Prepare a hard, level surface that is large enough to accommodate the associated equipment. Bear the following in mind: Drainage of the filter room or pit; Ventilation of the motor; Access for servicing and winterizing the equipment; Protection of the equipment. Make sure the bearing surface is leveled and straight to reduce vibrations.

Piping

The pump has male / female sockets to receive 1-1/2" (38mm) threaded fittings. Keep the piping as simple as possible, and avoid connecting an elbow directly to the pump inlet (use a length of straight pipe to allow a proper entry of the water). Keep as much of the suction pipe as possible below the water level of the pool. This will reduce the priming time but arrange the pipe to rise continuously toward the pump to prevent high spots that could form air pockets. Support the pipes independently so that they do not place strain on the pump. Install gate valves in the pump suction and pool return lines close to the filter system for convenient servicing of the equipment. These valves are essential if the equipment is installed below water level. Keep the gate valve in the suction line fully open during operation, and make sure that its gland is kept tight to prevent the entrance of air around the valve stem. Take care during installation to keep the pipes clean, and make sure that the suction system is absolutely airtight.

Electrical Connections

Check that the information on the pump nameplate corresponds to the power supply. Employ a competent electrician to make the wiring installation in accordance with the local electrical code. Every motor requires a fused disconnect switch. SHARKJET pumps are suitable for 115V only. SHARKJET pumps are equipped with a splash cover and a 25 foot (7.5m) three conductor cord ending with a three-pin grounding plug.

Starting Up

For 2-speed pumps, start and prime the pump at HIGH SPEED only. Do not change to LOW SPEED before the pump is working properly. At HIGH SPEED (3450 rpm approx.), the motor develops its full horsepower and the pump generates high capacity and pressure. Use high speed for maximum filtration at peak periods and whenever turbidity levels are high. At other times switch to LOW SPEED (1725 rpm approx.). For backwashing and vacuuming, HIGH SPEED is required. If the pump is supplied as part of a complete filter system, follow the starting-up procedure described in the separate instructions for the complete filter system. In other cases, proceed as follows:

1. Close the gate valves in the suction and return lines. Remove the cover from the hair and lint strainer and fill the pump completely with water. Replace the cover.
2. Open the gate valves in the suction and return lines and start the pump. If the pump fails to produce a full flow of water within four or five minutes, switch off the power and repeat Step 1. If the pump still fails to work, check for air leaks at the strainer cover, suction line connections, and valve stem glands before repeating Step 1.
3. After about ten minutes of operation check the pool return fittings for air bubbles. A continuous flow of air indicates leaks in the suction line. Locate and correct any leaks immediately.

CAUTION! Never run the pump without water in the pump case because lack of water can damage the shaft seal.

Controlling the Output

Keep the gate valve in the suction line fully open during operation. Should it be necessary to control the output, use a valve in the return line.

Lubrication

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

Draining

There are two drain plugs on the pump case. Note that the valves in the suction and return lines must be open to allow complete draining of the pump, but that other provisions may be necessary for draining the filter, heater, and pipe lines.

Maintenance

The pump can be serviced without breaking the pipe connections. Close the gate valves, SWITCH THE ON/OFF SWITCH TO OFF AND PULL THE PLUG FROM THE RECEPTACLE before starting work on the pump.

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 Information

Cleaning the Strainer Basket

Switch off the power. Close the valves in the suction and return lines. Remove the Strainer Nut and clear cover and lift out the strainer basket. Clean and replace the basket. Take care to clean the o-ring and make sure that it is well seated underneath the clear cover and place the cover back on the strainer body. Align and insert the Strainer Nut, hand-tightened only (fig.2). Re-open the valves. Put the pump back into operation.

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

Inspection

Inspect all parts of the pump for wear or damage, and order replacements as necessary. Check the shaft seal (10) carefully. Look for cracks in the ceramic seat. Check the seal faces for wear and nicks. Flex the rubber parts and check them for holes and cracks. Replace the complete seal if any part is damaged, or if the seal leaks. Do not use old parts.

Shaft Seal Replacement

Take great care while handling the shaft seal (10) to avoid damage to its carbon and ceramic sealing faces.

To Remove Old Shaft Seal

After dismantling the pump and removing the impeller as already described, pull the rotating parts of the seal from the hub of the impeller (9). Press or tap the stationary section of the seal from the motor bracket (13).

Fit New Shaft Seal

DO NOT USE OIL OR GREASE ON THE SEAL PARTS, because either may damage the thermoplastic material of the pump through overheating or chemical reaction. Make sure that the pump parts are clean, but be careful not to scratch the surfaces that come into contact with the seal. Moisten the rubber cup of the new stationary section with WATER. Protect the sealing surface with a disc of clean cardboard, and use a light mallet and small wooden block to tap the seal gently into the bracket (12). Be sure that the sealing surface faces the pump. Reassemble the bracket (12) onto the motor (15). Moisten the bore of the new rotating seal assembly with WATER. Push the assembly into position on the hub of the impeller (9) with its sealing surface facing outward. Prevent the motor shaft from rotating by inserting a screwdriver in the screw the impeller (9) to the shaft by hand. Put the diffuser back into place by snapping the Motor Bracket (12) and the diffuser (7) back together. Make sure that the diffuser o-ring (6) is still on. Make sure that the Main O-Ring (11) is properly positioned on the face of the Motor Bracket (12), then reassemble the bracket (12) to the pump Strainer Case(5). Tighten the screws (13) evenly by tightening its opposit in alternance. Reassemble the splash cover (20) and the base (23) (Fig. 3). Reinstall the pump and run it for 5 minutes to ensure that no water leaks from the pump case (which would indicate improper seal installation). If any water is observed leaking from the pump case, repeat seal installation procedure.
