Start-up

General Information

CHECK ROTATION:

Before pump is put into operation, rotational direction must be checked to assure proper performance of pump. Refer to illustration below to varify proper rotational direction for each model covered in this manual.

Hazardous voltage. Can shock, burn, or cause death. Disconnect power to pump before servicing.

Do not attempt any wiring changes without first disconnecting power to pump.

PRIMING:

Pump priming is the displacement of air with water in the pump and suction piping. Pump MUST BE completely filled with water when operating.

A self-priming pump only needs to be manually primed at the first start-up. Once primed, under normal conditions pump will reprime automatically at each subsequent start-up.

To prime, remove plug from top of pump case and fill case with water. Replace plug and start pump. Unit is equipped with a flapper type check valve which will

open at start-up and allow pump to evacuate air from the suction line. After several minutes of operation, pump will be fully primed and pumping water. Priming time will vary, depending on length and diameter of suction line.

STARTING (Electric Motor):

NOTICE: Never run pump dry. Running pump without water will overheat pump and damage internal parts. Always make sure pump is primed prior to start-up.

NOTICE: Refer to maintenance section if pump has packing for adjustment prior to start-up.

Prime pump by the above method. Turn on power to pump. Slowly open discharge valve until desired flow rate is achieved. Place the “Hand-Off-Auto” selector switch in the “Auto” position. The pump will start automatically when the pilot device signals the motor starter.

STOPPING (Electric Motor):

Pump will stop automatically when the pilot device de- energizes the motor starter. Turn the “Hand-Off-Auto” selector switch to “Off” position if you want to stop the pump while it is running.

ELECTRIC MOTORS:

Single Phase: Refer to wiring information on the motor plate to obtain proper rotation.

Three Phase: If pump runs backwards, reverse any two leads coming of incoming power (L1, L2, L3) until proper rotation is obtained. Reverse L1 and L2, L2 and L3, or L1 and L3.

Pump running backwards - Centrifugal pumps will still

pump liquids, however, GPM and head will be a fraction of the published performance.

ENGINE DRIVEN:

If engine is used for pump driver, check with engine instruction and operation manual or engine manufacturer to determine how rotation is defined, then use above illustration for proper connection.
