Warns of hazards that CAN cause personal injury or property damage.

NOTICE:INDICATES SPECIAL INSTRUCTIONS

WHICH AREVERY IMPORTANT AND MUST BE FOLLOWED.

THOROUGHLY REVIEW ALL INSTRUCTIONS AND WARNINGS PRIOR TO PERFORMING ANY WORK ON THIS PUMP.

MAINTAIN ALL SAFETY DECALS.

WARNING

UNIT NOT DESIGNED FOR USE WITH HAZARDOUS LIQUIDS OR FLAMMABLE GASES. THESE FLUIDS MAY BE PRESENT IN CONTAINMENT AREAS.

Hazardous fluids can cause fire, burns or death.

NOTICE: INSPECT UNIT FOR DAMAGE AND

REPORT ALL DAMAGE TO THE CARRIER OR DEALER IMMEDIATELY.

The Model 3885 is a 2" NPT discharge, 3⁄4" (19 mm) solids handling, submersible effluent pump. The Model 3886 is a 2" (50 mm) solids handling, submersible sewage pump. The Model 3887 is a 2" flanged (standard) 3" flange (optional) discharge, 2" (50 mm) solids handling, submersible sewage pump.

Lifting of Pump

WARNING

Hazardous voltage can shock, burn or cause death.

• Lift the pump with an adequately sized chain or cable

attached to the lifting handle (458). DO NOT damage electrical cables while raising and lowering unit.

DO NOT LIFT, CARRY OR HANG PUMP BY THE ELECTRICAL CABLES. DAMAGE TO THE ELECTRICAL CABLES CAN CAUSE SHOCK, BURNS OR DEATH.

Sliderail System

• The OPTIONAL Goulds Model A10-20 sliderail system is

recommended for proper installation.

NOTICE: FOLLOW THE INSTALLATION AND

OPERATION INSTRUCTIONS PROVIDED WITH THE SLIDERAIL SYSTEM.

• Installation of the sliderail system should locate the pump

opposite the influent opening, preventing stagnate areas where solids can settle.

• The pit floor MUST be flat under the sliderail base and

have sufficient loading capacity to support the entire weight of the assembly, including the sliderail base, sliderail guide, pump and all assorted piping.

Piping

• Discharge piping should be no smaller than 2" (51 mm)

diameter and kept as short as possible, avoiding unnecessary fittings to minimize friction losses.

• Install an adequately sized check valve (suitable for

handling 3⁄4" (19 mm) solids for effluent applications and 2" (50 mm) solids for sewage applications) in the discharge pipe to prevent backflow. Follow the check valve manufacturer’s installation instructions.

• Install an adequately sized gate valve ABOVE the check

valve for pump, plumbing and check valve maintenance.

• To deter air locking, drill a 3⁄16" (4.8 mm) hole, 2"

(50.8 mm) beyond the pump discharge connection.

• All piping must be adequately supported, so as not to

impart any piping strain or loads on the pump.

Access Doors

• Access doors can be single or double leaf design. Doors should include a lifting handle and a lock provision for tamper resistant operation. Standard and heavy duty steel or aluminum doors are available.

• The pit access door must be of sufficient size to allow for inspection, maintenance and crane or hoist service.

Liquid Level Controls

• Single float operation can be used on 1⁄3 and 1⁄2 HP models. Mounting of the float switch must be checked by the installer to insure proper turn on and turn off. The pump may be plugged directly into the piggy back style plug located on the cord of the float switch.

• The recommended float operation sequence used with a control panel requires a three or four float system. In the three float system, the floats are designated SW-1 for the bottom float, SW-2 for the middle float and SW-3 for the top float. In a four float system the fourth float is designated SW-4.

• Simplex Control – The rising liquid level raises float SW-2, turning on the pump. When the liquid level falls sufficiently, SW-1 will turn the pump off. If the influent is excessive, or if the pump fails to operate correctly, SW-3 will activate an alarm, which will remain on until manually reset.

• Duplex Control – The duplex control will alternate the two pumps, causing the lead pump to change at each system cycle. When equipped with three floats, the system will cycle the same as the simplex control, described above, except that the SW-1 will cause the lead pump to alternate.

• If the influent is excessive, or if the lead pump fails to operate correctly, the rising level will activate SW-3, turning on the lag pump and the alarm. As before the alarm must be manually reset.

• Four Float Control – The four float system operates the same as the duplex control system, except that float SW-3 will not turn on the alarm. In this system SW-4 turns on the alarm, which again must be manually reset.

• Several different float controls are available from the Goulds Catalog.

NOTICE:POSITION THE FLOATS SO THAT THEY

DO NOT SNAG OR TANGLE ON THE PUMP, DISCHARGE PIPING, OR OTHER EQUIPMENT.

• The lower most float turns the unit off and should be set as shown in the “TYPICAL PLUMBING and INSTALLATION” drawing provided in this manual.

• Increasing the distance between the SW-1 and SW-2 floats lengthens the running time. One (1) minute is the minimum recommended pump cycle time.

NOTICE:DURING PUMP OPERATION, INSURE THAT

THE LIQUID LEVEL DOES NOT DROP BELOW THE PUMP MOTOR FOR EXTENDED PERIODS. THIS CAN CAUSE THE PUMP MOTOR TO OVERHEAT, CAUSING MOTOR DAMAGE AND VOIDING THE WARRANTY.

Pump Motor Control Panels

• Control panels shall be in accordance with local and National Electrical Code requirements.

• Single phase installations shall be equipped with a Goulds’ “SES” or “A” Series panel, or AS A MINIMUM, a control panel with a properly sized magnetic contactor and a disconnect switch.

• Three phase installations shall be equipped with a Goulds’ “SES” or “A” Series panel, or AS A MINIMUM with a 3 pole circuit breaker, an across the line magnetic starter NEMA rated for the appropriate horsepower, ambient compensated Quick Trip Class 10 overload relays.

Wiring and Grounding

• Use only stranded copper wire to motor and ground. The ground wire must be at least as large as the wires to the motor. Wires should be color coded for ease of maintenance.

WARNING

Hazardous voltage can shock, burn or cause death.

Electrical supply MUST match pump’s nameplate specifications. Incorrect voltage can cause fire, damage motor and voids warranty.

Single phase motors are equipped with automatic thermal protectors which open the motor’s electrical circuit when an overload exists. This can cause the pump to start unexpectedly and without warning.

Some models are equipped with a 3-prong grounded plug and MUST be used in a grounded 3-wire receptacle. DO NOT modify the plug or remove the ground prong.

• Where cables must be spliced or connected to the motor leads, splices MUST be water tight. Commercially available potting or heat shrink kits may be used, if allowed by local or federal regulations.

Install, ground and wire according to local and National Electrical Code requirements.

Install an all leg disconnect switch near the pump.

Disconnect and lockout electrical power before installing or servicing pump.

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.

• 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.

WARNING

Hazardous voltage

FAILURE TO PERMANENTLY GROUND THE PUMP, MOTOR AND CONTROLS BEFORE CONNECTING TO ELECTRICAL POWER CAN CAUSE SHOCK, BURNS OR DEATH.

• If the three phase motor(s) rotation is backwards, reverse any two pump power cable leads at the pump control panel.

WARNING

Hazardous machinery

MOTOR OVERHEAT/OVER CURRENT SENSING DEVICES AUTOMATICALLY RESTART THE MOTOR UNEXPECTEDLY AND WITHOUT WARNING. THIS CAN CAUSE SEVERE PERSONAL INJURY.

• 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.

DANGER

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