Installation

If the pump is to prime from a well, a foot or return valve is required in the suction line. If it primes from a pond, pool
or container, a foot valve with a suction strainer is required on the suction hose.
A return valve is required in the suction line, installed directly on the suction port.
The suction hose or line must rise to the pump, to prevent trapping air. Before it is started, the pump and suction
line must be completely filled with water. To fill with water, remove vent plug (24) from pump casing (next to the
discharge port) and fill clean water through the discharge port into the casing, until it is completely filled an all air
has vented. Reinstall vent plug and connect a pipe or hose to the discharge port.
With too little or no water the pump will not prime, running it dry will damage the duocone seal.
No warranty for a duocone seal damaged by silt or sand.
To prevent damage to the duocone seal check with your dealer for suitable filters offered by Elektra Beckum.
If the pump does not start when new or not having been in use for a longer period, turn pump manually. With the
help of a screw driver put through the fan cover, turn motor fan until shaft has worked free.
Caution! Always disconnect from power before attempting to free shaft.
Note: Without a check valve the water level in the suction line can drop. This can cause damage to the pump
when it has to start priming again.
➔
Always install a check valve in the suction line. It is recommended to fit the check valve directly to
the pump's suction port.
➔
Use only hose couplings with adjustable collar to prevent the ingress of air (see accessories for
pumps).
