IMPORTANT INFORMATIONS
 The automatic thermal overload protection shuts the motor off when it overheats because of low voltage, trash in the
pump or other problems. Normally, motor cools in 10 minutes and restarts automatically.
 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. The grinder pump
is designed for continuous underwater operation. The induction motor is insulated against heat and moisture in accordance
with Class B 265F (130C) regulations.
 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.
 Mostly the grinder pump settled in indoors or outdoors, if use in 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.
 Grinder installations should be checked yearly for debris and/or build up which may interfere with the “ON” or “OFF”
positions of variable level float control switches. Repair and service, other than cutter assembly maintenance, should be per
formed by experienced authorized service stations only, so Do not attempt to turn inlet cutter locate down bottom of the
unit with fingers. Use a wrench when checking or removing cutter, always unplug the power when it require to be repaired.
 If you use Junction box conduit combined in outdoors or indoors, it must be installed with watertight grade.
 Pump motors are available in single and three phase design. Single phase motors require a starting relay, starting
capacitor and a run capacitor, which are mounted in a control panel (ref. figure), and three phase pumps require overload
protection in the control panel.( or add in magnetic Breaker.)
INSTALLATION STEPS
Grinder pumps must be installed in a tank that is vented in accordance with local plumbing codes. This pump is not to be installed in
locations classified as hazardous in accordance with the National Electrical Code, ANSI/NFPA 70. Installation should be at a sufficient
depth to ensure that all plumbing is below the frost line.
Installation and piping instructions are included with the control panel, rail system and basin instruction. If pump is being retrofitted
to an existing rail system, accessory parts may be required. Consult the factory and advise make and model of rail system being
used.
Regarding the indoors usage, please ref. below drawing to install concern equipment to complete the whole set.
Unplug pump when liquid supply is exhausted. Overheating due to dry running will damage impeller or weld it to the pump body.

BASIC OPERATION DESCRIPTION
The grinder pump is designed to grind and pump domestic sewage. The pump is a semi-positive displacement, progressing cavity
pump. The grinder pump consists of a pump assembly with an integral sewage grinder and the shredder device (we name it cutter
ring, see construction). The contactor/relay coil is energized and the relay contact points close, providing electrical power to the
pump motor. When the motor starts and runs, the grinder pulverizes any solids. The slurry is then pumped by
the pump rotor and stator until the liquid is lowered to the shut–off level( if you combined with piggyback control plug or control by
float switch). This reduces pressure on the diaphragm of the on–off switch, which opens the electrical contacts in the switch, opens
the contacts in the contactor, and removes power to the motor.
Mostly the grinder pump been combined with the alarm indicator ( light or buzzer) in order to alert the owner, or control it with
float switch or other equipment, but here in this manual, we don’t describe much about it.
LOCATION OF PUMP SET INDOORS
Please ref. the attached station recommended drawings as below, there except the item 5 and 6,the other items will be needed to
support the indoors installation as the list from 1 to 4, from 7 to 12 items where:
•Alarm panel — ensure that the alarm panel is properly mounted and free of any damage. Verify that the alarm panel has been
wired properly in accordance the alarm’s product instruction. The other parts setting please ref. same grade manual as the tank
construction, there are many construction issue need the basement maker and plumber to take care about.
•Supply voltage in accordance with the voltage specified on the nameplate.
Please noted the electrical system servicing accordance with below reminding.
1. Ensure that the electrical power supplying the alarm panel is “OFF.”
( if you really add the alarm panel onto the system.)
2. Ensure that the grinder pump (double) and alarm (single) circuit breakers
in the alarm panel are in the “OFF” position.
3. Turn “ON” the power to the alarm panel from the building service panel.
( for Alarm setting usage.)
4. Using a test (volt) meter, verify that the incoming panel voltage is within 10%
of the pump nameplate voltage (for 230V pump, voltage at panel must be
207 V to 253 V). If the voltage is outside of this range, do not continue with
Station start-up. The voltage problem must be corrected prior to proceeding.
PIPING OF INDOORS USAGE
Be sure the discharge must add in check valve connected to the discharge pipe line.
For the below recommended drawings, the type, size and venting requirements of
the inlet pipe must be in accordance with all national and local plumbing codes.
The recommended drawing is a sewage handling pump and requires ventilation for
proper and safe operation, the drawing stated the sewer inlet pipe is near
4” outside diameter.
For the piping of right side drawing, please noted, This set of instructions is for factory
Pre pack aged indoor systems only. If your system is a field assembled indoor system,
use below info as instruction and a guideline.
1.
Review where the unit will be in stalled. Determine where the power feed, inlet pipe,
discharge pipe and vent as well as the control panel you should assembly.
2. There should be no reason to remove the cover from the basin. Pump and
float switches are already set inside the basin, so for indoors usage, there is no reason
to open the top cover.
3. Dig an adequate hole for the basin, and you must consider the power inline, it must
Within 15’, and please set the basin in the hole and connect the 4" inlet as the drawing displayed.
Caulk or gasket the inlet hub to pipe. Backfill around the basin with specified media . Care should be taken not to damage
components or leave voids when backfilling. Finish grade of floor should be poured in place around the top 6" of
the basin assembly.
4. Connect the discharge pipe, valves and vent according to all applicable National, State and Local plumbing codes.
5. Mount the control panel on the wall within 15' of the system, Connect the float switch and pump cords.
6. Clean any debris out of the basin. Fill the basin with water and check the system for proper operation.
7. Always recording the system start-up data for future reference.
8.
Seal and secure the inspection plate to the lid using the proper bolts and sealant. And then pouring concrete around the system
can to ready to start to test the pump running.
FIELD ASSEMBLED INSTALLATION
1. Installation and piping instructions had displayed in the total whole construction with the control panel, for rail system and basin
instructions. If pump is being retrofitted to an existing rail system, accessory parts may be required. Consult the factory and advise
make and model of rail system being used.
2. Refer to the appropriate Indoor prepackaged instructions for more information on system installation.
3. All electrical connections including pump to control box and power supply to control panels must comply with the “National
Electrical Code” and applicable local codes. Conduit and panel enclosure openings must have a gas-tight seal. Installation of electrical panels and connection should be made by a qualified licensed electrician.
4. A properly sized disconnect switch, supplied by others, shall be installed on the service side of the pump and control panel.
5. When installing a pump with a check valve, or a rail system with a check valve, you must give the pump case time to fill to help
prevent air lock when lowering the unit into the liquid, when the pump has no air vent located behind the discharge, we
recommend to install an extra air vent hole (3/16") may be drilled in discharge pipe below the check valve to help prevent air lock.
This drilled hole must be cleaned before each reinstall. After the pump is installed, run the unit submerged to assure the pump case
is filled (Water should come out of 3/16" diameter hole).
6. Excavate a hole of sufficient depth and width to accommodate the tank,
underground piping and required backfill material as well as providing adequate
working space for plumbing and electrical connections. The base of the excavated
hole should be level and prepared with proper bedding material, such as gravel,
in accordance with the site engineer’s requirements. The depth of the excavation
must be sufficient to accommodate the bedding material and tank burial to
approximately 1” below the upper flange surface. The size, shape and shoring
requirement of the excavation will be based on the soil conditions and should be
in accordance with the site engineer’s recommendation and safety requirements.

PUMP OPERATION
STARTING THE GRINDER PUMP
Warning: Severe injury may result from accidental contact with moving cutters. Keep clothing, hands and feet away from cutters any
time power is connected to the pump.
1. Grinder pump is single phase; no rotation check is necessary.
2. Run water into sump until motor is covered.
3. Open gate valve in discharge line.
4. Turn pump on. If pump runs and sump liquid does not pump down, stop pump and close discharge gate valve. Then lift pump
until sealing flange is open to vent off trapped air. Lower pump, open discharge valve, and start the pump again.
5. Level control should be set so that pump turns off when level is about 2 inches above inlet of pump suction and turns on when
level is about 2 inches above motor.
6. If problems occur check power source. Make sure a separate supply line is available. Verify voltage supply.
7. Check resistance of windings. (See Chart, page 5.) If not within guidelines, return pump to authorized service or repair center.
As the motors are oil filled, no lubrication or other maintenance is required. Pump should be checked every quarter for corrosion
and wear.
8. If the pump settle in previous indoors usage, it must double check with the alarm as well as to the control box.
Caution: Never work on pump with power on. Make sure that the ground wire is securely connected and that the unit is
properly grounded in accordance with local codes.
Caution: Severe injury may result from accidental contact with moving cutters. Keep clothing, hands and feet away from cutters
and cutter ring any time power is connected to the pump.
Replacing Grinder Parts:
If necessary to replace grinder parts because of wear or to inspect for clogging:
1. Close gate valve at pump discharge.

6. Clean the surrounding of the cutter ring with a wire brush and file smooth any nicked slots.
7. Before replacing grinder cutter, make sure cap screw in bottom of pump shaft is tight.
8. Make sure the cutter and the shaft turns freely by hand after reassembly. There should not be any binding or tight spots
when fasten the cutter done.
9. If there is any rub or drag on the shredding ring, loosen the 4 bolts in the CUTTER ring seat and tap lightly with the hammer to
loosen. Retighten the bolts. Be sure to tighten the bolts evenly, applying pressure on all 4 bolts equally.
DO NOT COMPLETELY TIGHTEN ONE BOLT BEFORE TIGHTENING THE OTHER BOLTS. THIS WILL CAUSE MISALIGNMENT AND
LOCKING OF SHREDDING RING AND CUTTER.
Let pump cool for at least 20 minutes before attempting to service. Motor may be extremely hot. Personal
injury may result.
Always disconnect the electrical supply before attempting to install, service, or perform any maintenance. If
the power source is out of sight, lock and tag in the open (off) position to prevent unexpected power
applications. Disconnect electrical cord from power supply. Failure to do so could result in fatal electrical
shock. Only qualified electricians should repair this unit. Improper repair could result in fatal electrical shock.
WARNING ITEMS
