2. Introduction

2-1 INTRODUCTION

This manual was prepared to assist you in the correct installation, operation, and maintenance of your Liberty pump. Please read it completely before installing the pump. Make certain that you are familiar with the contents, and the chapters on installation and operation are fully understood before running the pump.

Liberty Pumps are designed for minimal maintenance. However, regular checks will ensure longer life and greater operating reliability.

WARRANTY: No repair work should be carried out during the warranty period without prior factory approval. To do so may render the warranty void.

SERIAL #: In all correspondence and reports, make certain that the pump serial number is given.

2-2.1 DESIGN OF PUMP

WARNING

The grinder pump contains metal parts that rotate at high speeds. Be careful around pump base while power is connected. Make sure that the pump is either in the tank or clear from people and wires when in operation.

1. Liberty LSG and LSGX-Series grinder pumps are designed for continuous underwater operation. The motor and pump form a close coupled, watertight unit. The induction motor is insulated against heat and moisture in accordance with Class B 265F (130C) regulations.
2. A thermal overload protector is imbedded in the stator windings. This is connected in series and wired to shut down the pump if overheating occurs. The overload switch resets automatically when the motor cools.
3. The motor is protected against damage from water entry by two seals. The lower seal is a Viton lip seal. The upper seal is mechanical, consisting of two silicon-carbide faces.
4. The impeller and volute are designed for efficient flow characteristics and clog-free operation. The hardened cutters grind solids and fibrous matter into small particles that can be safely pumped through small diameter piping.
5. For sewage systems, consult local plumbing codes on requirements of venting the tank. The pump shall not be installed in locations classified as hazardous in accordance with the National Electrical Code, ANSI/ NFPA70.

NOTE: The major material of Liberty LSG and LSGX-Series pumps is cast iron. They should not be used to pump corrosive liquids.

3. Mechanical Installation

3-1 INSPECTION UPON RECEIPT

The shipping container should be immediately inspected for damage that may have occurred in shipment. Exercise care in opening the shipping container to avoid damage to the pump. Remove any blocking and cushioning from within the container.

Check all cushioning for spare parts before discarding. Visually check the pump and any spare parts for damage. Check for damaged electrical wires, especially where they exit the motor housing. Contact the Liberty Pumps Customer Service Department to report any damage or shortage of parts. Turn the hex socket head cap screw at the center of the cutter wheel on the bottom of the grinder several rotations clockwise. This will insure that the impeller and cutter are free of any seizure due to prolonged storage. If the impeller is not rotated manually prior to installation, the pump may fail to activate. If the impeller's rotation is difficult or completely resistant, contact the Liberty Pumps Customer Service Department.

3-2 STORAGE BEFORE USE

Liberty pumps are shipped from the factory ready for installation and use. They should be held in storage if the pump station is not complete. If storage is necessary, the pump should remain in its shipping container. It should be stored in a warehouse or storage shed that has a clean, dry temperature-stable area where the pump and its container should be covered to protect it from water, dirt, dust, etc. The ends of the cables - (plugs) must be protected against moisture.

CAUTION

AT NO TIME SHOULD THE PUMP BE STORED WITHIN AN INCOMPLETE WET PIT. THE PUMP SHOULD NOT BE PLACED INTO THE PIT UNTIL IT CAN BE FULLY OPERATED.

LONG TERM STORAGE

1. If it is necessary to store a pump for a long period of time, it should be stored indoors in a clean, dry temperature-stable environment. The pump should be covered to protect it from dust, dirt and water. The plug end of the cable must be protected against moisture.

2. Do not allow the pump to freeze.

3. Prior to installation, the pump motor should be rotated to ensure the seals and cutters are free spinning.

4. Installed pumps which are idle for long periods of time should be manually operated through the breaker panel once a month to lubricate the seals. Turn off the breaker, unplug the piggyback switch, and plug the pump directly into the wall socket. Turn the breaker on for 30 seconds. Turn the breaker off, and then plug the piggyback switch back in. (refer to Section 4-1)

3-3 PUMP INSTALLATION

WARNING

THIS PUMP IS NOT TO BE INSTALLED IN LOCATIONS CLASSIFIED AS HAZARDOUS IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70.

- Grinder pumps must be installed in a tank that is vented in accordance with local plumbing codes. Installation should be at a sufficient depth to ensure that all plumbing is below the frost line. If this is not feasible, remove the check valve and size the basin and/or adjust pump differential to accommodate the additional backflow volume. Consult the factory for details on how this should be done.

The Omnivore Grinders may be guide rail mounted using Liberty's GR20 guide rail base, or stand-alone. (See Figure 3, page 11) They may be installed as a completely packaged simplex (single pump) or duplex (two-pump) system. Installation of the pump shall be in accordance with state and local codes and performed only by qualified personnel. Typical installations consist of a guide rail mount in a fiberglass, concrete or polyethylene tank. This section assumes guide rail installation.

CAUTION

1. Liberty GR20 Guide Rail systems feature a self-aligning mounting bracket. Using the lifting chain, slip the pump bracket over the upper guide rail bracket. Lower the pump at an angle down the guide rail into the tank. (See Figure 3, page 11)

2. As the pump nears its final position, the straightening rib squares the pump bracket with the guide bracket ears. When the pump bracket ears hook the guide bracket ears, the chain will slacken.

3. Grasp the lifting chain and shake the pump to ensure a good seat with the gasket. The pump is suspended by the bracket ears. The weight of the pump compresses the gasket against the mating flange of the guide bracket base.

4. The lifting chain may be removed from the hoist and hooked near the upper guide rail bracket.

IMPORTANT: For 3-phase pumps, check for proper rotation before installing pump into basin. See figure A for proper rotation.

Fig. A – Proper impeller rotation, three phase models

ROTATION Bottom KICK

Check three phase pumps for proper rotation prior to installing pump(s) in basin. To change rotation, reverse any two of the three power leads to the pump. Code the wires for reconnection after installation.

4. Electrical Connection

AFTER THE PUMP IS INSTALLED, THE ELECTRICAL CHECKS OF SECTION 4 MUST BE PERFORMED.

1. Plug the Piggyback switch into a 6-20R receptacle. The receptacle must be wired to a 30-amp breaker. Be sure to have the breaker turned off before plugging in the switch.
2. Plug the pump power cord into the piggyback switch as shown.
3. The pump is ready to test and your breaker can be turned on.

4-5 STEPS TO BE TAKEN BEFORE ENERGIZING

1. Retighten all field-made connections. Retighten all factory-made connections. These may have loosened due to shipping and handling vibrations.
2. Check the security of mounting hardware.
3. Check the enclosure to see that it has not been damaged in such a manner as to reduce electrical spacing.
4. Rotate the cutter wheel with the hex socket head cap screw to verify movement and lubricate the seals.
5. Ensure that no wires or other obstacles are in the way of the pump cutter.
6. Conduct an electrical insulation resistance test to make sure that the control panel is free from short circuits and ground faults. This should be done both phase-to-phase and phase-to-ground.
7. MOTOR OVERLOAD PROTECTION: The pump motor is protected from locked rotor and running overloads by a thermal overload integrally mounted to the motor (Single Phase Only). No adjustments are required.
8. Check to determine that all grounding connections are made properly
9. If a panel is used, remove all debris, scrap wire, etc., from the control panel interior before closing the doors. Install covers, close doors making certain that no wires are pinched and that all enclosure parts are properly aligned and tightened.

WARNING

ENERGIZING THE CONTROL PANEL OR BREAKER FOR THE FIRST TIME IS POTENTIALLY DANGEROUS. LICENSED ELECTRICAL PERSONNEL SHOULD BE PRESENT WHEN THE PANEL OR BREAKER IS ENERGIZED FOR THE FIRST TIME. IF FAULTS CAUSED BY DAMAGE OR POOR INSTALLATION PRACTICES HAVE NOT BEEN DETECTED, SERIOUS DAMAGE CAN RESULT WHEN POWER IS APPLIED (REFER TO SECTION 5).

4-6 FLOAT SWITCHES

1. The pump's on and off cycles are normally controlled by a "piggy back" float switch attached to the side of the pump, or by hanging switches in the wet well. Refer to panel or switch instructions for proper electrical connection

4-6.1 FLOAT SEQUENCE- PIGGY BACK (AUTOMATIC MODELS LSG202A & LSGX202A)

1. As the liquid level in the wet well rises, the float tilts, closing the switch. This starts the pump.

2. The pump runs until the liquid level falls below the "PUMP OFF" level of the float (Factory set at 7" minimum), emptying the wet well.

4-6.2 FLOAT SEQUENCE-SIMPLEX (MANUAL MODELS)

1. As the liquid level in the wet well rises, the "PUMP OFF" float tilts, closing the switch (This level must be set at a minimum of 7"). As the liquid level continues to rise, the "PUMP ON" float tilts. This switch closes, starting the pump.

2. The pump runs until the liquid level falls below the "PUMP OFF" float, emptying the wet well.

3. In the event of a malfunctioning float switch, control relay or pump, the liquid level rises and tilts the "HIGH LEVEL ALARM" float. The alarm system will activate.

4-6.3 FLOAT SEQUENCE-DUPLEX (MANUAL MODELS)

1. As the liquid level in the wet well rises, the "PUMP OFF" tilts, closing the switch. As the liquid level continues to rise, the "LEAD PUMP ON" float tilts. This switch closes, starting the lead pump. The pump runs until the liquid level falls below the "PUMP OFF" float, emptying the wet well.

2. On the next rise of the liquid level, the other pump will start on the "LEAD PUMP ON" signal. The pumps will continue to alternate their cycles.

NOTE: The ON/OFF float switch differential should be set as to not exceed 12 starts per hour.

1. If the liquid level rises to the "LAG PUMP ON" float, the second pump will start. Both pumps will run until the liquid falls below the "PUMP OFF" float, emptying the wet well.

2. In the event of a malfunctioning float switch, control relay or pump, the liquid level rises and tilts the "HIGH LEVEL ALARM" float. The alarm system will activate.

4-6.4 FLOAT SWITCH INSTALLATION

The engineering drawings will normally specify the levels for pump start and stop and high level alarm. If they are not specified, these guidelines should be used to determine float switch locations.
