Locate pump as close as possible to the fluid source thus making the suction line as short and direct as possible, using tubing on

the suction that cannot collapse, such as a reinforced type.

Support the tubing independently of the pump. Use clamps to secure and seal the tube to the pump.

These pumps are liquid lubricated. How they are mounted, and water condition/quality are important.

Thoroughly clean and flush the system before installing the pump

Plumbing valves, fittings, etc. should be positioned to avoid leakage onto the pump.

Ensure plumbing is designed and installed in such a way that the pump will fill with water when the plumbing system fills, to

avoid air locking and dry running.

If replacing an older Laing SM9xx series circulation pump, ensure that any inline strainer is removed prior to installing an E-10.

The increased flow of this pump through a restriction in the suction (such as a strainer) can result in pump starvation and dry

running damage.

Mounting

For installation purposes, the arrows on the side of the pump housing indicate the direction of water flow through the pump.

Ensure the pump and piping is adequately supported. Do not mount the motor above the wet end. Correct orientation of the

pump includes mounting horizontally or vertically with suction facing upward only. The pump can roll on its foot (E-10) to allow

different angles of discharge alignment. Do not position with discharge port lower than inlet / suction port. This helps prevent

air locking.

Ensure the pump mounting is secured to a solid base with pan head self tapping screws.

Operation

Completely fill the plumbing system before operating the pump. Do not start the pump until the plumbing system has been

filled. Make sure isolation valves are fully open and the pump is flooded with water.

Purge air from the plumbing system prior to operating the pump. This can be achieved by loosening the plumbing connection at

the pump to allow any air present, to escape.

These 2 steps are very important. The pump can never be allowed to run dry as this can severely damage the pump and will void

warranty.

Operate the pump. Ensure water is pumping through the plumbing system. Turn off immediately if no water is flowing within 30

seconds. Once running correctly, recheck after 5 minutes to ensure continued proper operation.

It may be necessary to open a discharge valve, port or fixture to ensure all air is purged. The pump should be running quietly. If

gurgling is heard, it may mean that air is still in the system. Turning the pump on and off several times will generally clear

remaining air. If gurgling noises persist, recheck and purge the system (note that ozone injection can make a gurgling sound at

the injector and not be a pump issue).

Dry run protection. Pump motors are fitted with dry run protection to preserve the MOTOR. If a dry run condition occurs, the

motor will stop and restart numerous times in the attempt to purge air. This does not guarantee protection of the wetend /

rotor bearing as dry running will cause failure NOT covered by warranty. This dry run motor protection prevents motor failure

provided it's addressed when noise is audible from the pump. If left unchecked it can result in seizure and windings or electronic

failure. A failed rotor only, due to dry running or chemical / water condition damage, can be ordered from spatex and replaced

rather than a complete pump. If the windings or electronics are damaged, a replacement pump is required.

*Dry running is a term referring to operation of the pump with insufficient water flow or a lack of water present, resulting in

overheating.

Trouble Shooting

Motor will not start or run:

Improper electrical connection, blown fuse or circuit breaker, loose or broken wiring, foreign object stuck in impeller, motor

failure, dry run motor protection has operated.

Pump will not prime:

leak, kink or obstruction in suction line, pump is worn, dirty / blocked filter

Little or no discharge:

Air in pump, suction blockage, head to high, blockage in pump, pump not running, dirty / blocked filter
