NOTICE: FOLLOW THE SPLICE KIT MANUFACTURER’S INSTRUCTIONS.

•Where wire splices are used, follow one of these procedures:

•Butt join the wires using properly sized and correctly crimped Sta-Kon™, or equivalent, connectors. Insulate and water proof each joint using heat shrink tubing equipped with a self contained sealer. Apply heat evenly from a torch until adequately sealed.

OR

•Use plastic insulators and a neoprene gasket sleeve set with properly sized and correctly crimped Sta-Kon™ connectors. Place a cap and gasket on each wire end, center insulator body over splice, insert the sleeve into the body as far as possible, hand tighten caps.

•In the case of multiple conductors, stagger the joints.

•After installing the pump into the containment area, with adequate submergence, open the discharge valve fully. Start the unit using manual controls. If flow is appreciably less than rated performance, pump may be air bound. To expel trapped air, jog the unit several times, using the manual controls.

•Have a qualified electrician take current measurements on the single or all three phases. Record these readings in the space provided in the “OWNER’S INFORMATION ” section of this manual for future reference.

•The unit is now ready for normal operation. Place the controls in the automatic position.

Operation

•If the unit has been stored for an extended period, check the oil level in the motor and seal chamber, to insure that they are full, using the following procedures:

•Motor Cover – With the pump in the upright position, remove the oil fill plug (358E), being careful that nothing enters the motor. The oil level should be above the top of the motor. With the correct oil fill as required. DO NOT over fill.

•Cable Gland Assemblies – Re-torque both the power and sensor cable glands to values given in step 10 of

“POWER CABLE REPLACEMENT ”.

•Before lowering the pump(s) into the containment area, three phase units should be jogged to insure correct rotation. See the motor rotation arrow on the motor cover (341). Check both pumps in a duplex operation.

NOTICE: MOTOR STARTUP TORQUE, “KICKBACK”, WILL CAUSE THE MOTOR TO TWIST IN THE DIRECTION OPPOSITE ROTATION. INSURE THAT THE PUMP ASSEMBLY IS ADEQUATELY RESTRAINED.

Maintenance

	SHOCK, BURNS OR DEATH.
	UNIT MUST BE FLUSHED AND
WARNING
	DISINFECTED, INSIDE AND OUT,
	PRIOR TO SERVICING.

Biohazard can cause serious personal injury.

Periodic Maintenance

NOTICE: ROUTINE PERIODIC INSPECTIONS ARE REQUIRED AND SHOULD FOLLOW THE FREQUENCY AND MAINTENANCE SCHEDULE PROVIDED.

! DANGER

Hazardous Machinery

DO NOT PLACE HANDS IN PUMP SUCTION WHILE CHECKING MOTOR ROTATION. TO DO SO WILL CAUSE SEVERE PERSONAL INJURY.

FREQUENCY	REQUIRED MAINTENANCE
MONTHLY	• Duplex Units – Check for even
	operating times. Uneven operation
	times indicate a defective unit, float
	switch or control.
	• Unimpeded float operation.

NOTICE: DO NOT SWITCH PRIMARY POWER LEADS COMING INTO A THREE PHASE DUPLEX CONTROL PANEL, THIS WILL REVERSE ROTATION OF BOTH PUMPS.
