SAVE THESE INSTRUCTIONS
For the complete use and understanding of this product it is recommended that this manual is thoroughly read and understood. Failure to do so may result in damage to this product.

The Fluval Sea Aquarium Pump is designed to be used immersed in a sump tank as well as outside water, connected with proper tubing to a tank. The pump is designed to treat clean water only; use an adequate pre-filter to avoid large particles from entering the pump.
WARNING: Always unplug or disconnect all appliances in the aquarium and sump tank from the electrical supply before installing, repairing, maintaining or handling the equipment in the water. IMPORTANT: To achieve the best pump operation, always use the largest bore hose possible. Avoid sharp bends in the hosing; gradual curves are preferred.

INSTALLATION
The aquarium pump should always be placed on a firm base using its proper mounting base with rubber feet.
WARNING: Do not plug in the pump before it is correctly and fully installed.
a) Submersed inside a sump tank: Choose the correct position for the pump, to avoid bending of the tubes as much as possible. Screw the threaded fitting onto the pump intake nozzle and connect an appropriate hose. The use of flexible hosing instead of rigid pipes is recommended to reduce vibration transmissions.
IMPORTANT: To reach the best pump performances be sure the water level in the sump tank is proper and adequate. This avoids the pump from sucking in air and creating a water vortex. If needed, a 90° threaded elbow fitting (not included) can be installed on the pump intake. NOTE: The 90° elbow has to be installed facing downwards.
b) Outside a tank (in-line): The pump should be primed first before plugging it in. Use appropriate fittings to connect the pump to the tank by means of a pipe or a hose. The use of a ball valve, fitted to both the inlet and the outlet pipe will be of help when servicing the pump to disconnect it from the system. When connecting the pump, the use of flexible hosing is suggested to reduce vibration transmissions.
Pump operation: Once the pump is fully installed, insert the plug into the electrical receptacle/socket to start.

INTERNAL OVERFLOW AREA AQUARIUM DRIP LOOP (PUMP POWER CORD) SUMP PUMPMAINTENANCE
WARNING: Always unplug or disconnect all appliances in the aquarium from the electrical supply before installing, repairing, maintaining or handling the equipment in the water. NEVER LIFT THE PUMP BY THE CORD.
To avoid shortening the life of the pump, follow these simple maintenance procedures:
- Once a week, verify that the pump performance is satisfactory. If you detect a drop in pump performance (such as a decrease in water flow from the pump to the aquarium) the pump should be cleaned (impeller, impeller well, and impeller cover) to restore the water flow to its original performance level (see Cleaning).
- When necessary, or at least once a year, clean the pump motor completely (impeller, impeller well, and impeller cover) and check that no limestone deposits, which could jeopardize pump operation, are present.
- To keep the pump in good working order, always replace any worn parts.
- Check the hosing integrity regularly and especially after maintenance to ensure there are no kinks in the hosing that would impede pump performance.
- The pump motor has no user serviceable parts. If the motor or the electrical cord is damaged, discard the pump.
CLEANING
CAUTION: The pump motor includes a high quality ceramic shaft that provides long-lasting, reliable performance when properly maintained. However, extreme care should be taken when handling the shaft during maintenance. Avoid dropping or pressing too hard on it to avoid breakage or hairline fractures, which may cause the shaft to snap while in operation.
WARNING: Always unplug or disconnect all appliances in the aquarium from the electrical supply before installing, repairing, maintaining or handling the equipment in the water.
Model SP2
- Remove the pump from the aquarium tank or in-line setup; remove the pump base.
- Using a Phillips screwdriver (cross-headed screwdriver), unscrew the screws and remove the impeller cover from the pump motor.
- Grasp the rotor and pull gently to remove the impeller assembly (with magnetic ceramic shaft).
- Remove the rotor and the rubber damper (between the impeller and the rotor) to be able to clean impeller.
- Remove the seal ring and O-ring
- Clean all components in clean water only, using a small, nonabrasive brush, if necessary. DO NOT USE DETERGENTS OR OTHER CHEMICAL CLEANERS which could damage the pump and pollute the aquarium.
- Reassemble all components with care in reverse order. Ensure that the impeller bearing, bushing and Rubber Support are correctly placed at the bottom of the impeller well. Ensure that the rubber damper (between the impeller and rotor) is replaced correctly.
- Before replacing the pump back in the tank or set-up, rinse the threaded fittings in clean water to remove any residual dirt or debris.

a) The threaded fittings have to be hand tightened until they fully fit on input / output pump threaded connections.
b) During maintenance operation check that the pump's Input and Output threaded connections are free from dirt, debris and/or any obstructions to avoid problems during the threaded fittings installation. Clean the pump's Input and Output threaded connections by rinsing them in tap water.
c) To avoid damaging the pump's threaded connections, the pump itself must be always be stable and securely installed on a flat and levelled surface.
d) Using a Phillips (cross-headed) screwdriver, tighten the screws until they fully fit. Afterwards tighten an additional quarter turn the screws.
CAUTION
a) The threaded fittings should easily assemble/disassemble. If you feel you are applying excessive force in order to fit the threaded fitting coupling to the pump's corresponding threaded connections, then do not continue the installation as the threaded connections could be damaged. Proceed by removing the threaded fittings and cleaning both the connections and the fittings in tap water.
b) Extreme care should be considered when using accessories not included with the pump. Do not use tooling for tightening connection accessories as the force produced can damage the pump threaded connections.
c) Do not use glues or sealants for fixing on the pump's threaded fitting or different connection accessories not included with the pump first sale configuration.
d) Before installing the threaded fittings, it is recommended, as a good and common practice, wrapping the input / output pump threaded connections with some Teflon.
PUMP BASE
a) Pump must always be stable and fixed. It has to be secured installed on a flat and levelled surface.
b) In case of difficulty removing the pump from its base, check that the pump based is free from dirt. Just in case clean the pump and the pump base in tap water.
TROUBLESHOOTING TIPS
LOW FLOW FROM PUMP
- Check the hose for blockages.
- Check that the pump is free of dirt and debris.
NO FLOW FROM PUMP
- Check that the power supply is on.
- Check that the plug is correctly connected to the electrical receptacle/socket.
- Check the hose for blockages.
- Check that the pump is free from dirt, debris and/or any obstructions.
- Check that the Impeller Assembly is free from dirt, debris and/or any obstructions. If the Impeller Assembly is damaged it must be replaced with the appropriate spare part.
REPLACING THE BUSHING AND O-RING / BUSHING AND RUBBER SUPPORT
Though the bushing is made of very resistant material, it is prone to wearing in certain conditions. For this reason, it is recommended that you replace it whenever the impeller unit is replaced. Follow the instructions provided with the replacement parts package. Once you have replaced the Bushing and O-Ring (Fluval Sea Aquarium Pump SP4, SP6) or Bushing and Rubber Support (Fluval Sea Aquarium Pump SP2), reassemble all parts with care.
