1.1. Be sure to provide an adequate grounding and install with leakage breaker to prevent the users
from serious electric shock injury.
1.2. Make sure the voltage of the power supply are identical to the indications of the nameplate
(label) on the pump. Do not plug into other voltage and phase than indicated on the nameplate.
1.3. Do not have a dry-run in the air, it will damage the pump.
1.4. Do not use the electrical cable to carry, lift or lower the pump. Please carry by the pump handle.
1.5. Extension of power cable:
When the power cable has to be extended, select the proper cable size within the allowable
extension. If cable is extended too far, a drop in voltage may occur, which will stop the running
of the motor and damage the pump.
2.1. When the pump stops suddenly (by the motor protection device):
The motor protection device is built-in and shuts off the circuit automatically to
prevent the motor from burning-out when the motor is overloaded due to clogging by
foreign particles or when plugged-in to wrong power source (Voltage, Frequency, etc.).
Should the pump stop suddenly, please check piping, pump itself, connection of electrical cable
to power source, etc. The motor protector always automatically trips-off in a few seconds if there is any
abnormality. Please resume the operation after clearing the trouble and leave the pump as it is.
2.2 Please consult your local dealer or company from which the pump was purchased if you are
unable to solve the problem. Unauthorized personal is prohibited from disassembling or
assembling the pump as it will probably result in inferiority in performance or damage to motor.
YOU DO NOT NEED TO TAKE ANY SPECIAL CARE ON THE PUMP AFTER OPERATION, HOWEVER, YOU MUST
BE WARN OF THE FOLLOWINGS:
3.1. If a freezing temperature is predicted, lift up the pump from water and re-install it in dry condition.
3.2. If pump is left in the water for a long period of time without running, rust and other possible
 oatingparticalswillaccumulateinthepump,whichwillinevitablyshortenthelifeofthepump.
 Inthiscase,letthepumprunincleanwaterandremoveoatingparticalsfrominsidethepump.
Re-install it once dried.
THE MOST EFFICENT, VERSATILE AND COST-EFFECTIVE PRODUCTS YOU’LL EVER USE!
- Draining from buildings and sanitary facilities.
- Water treatment process in sewage treatment yards.
- Sewage waste containing slender material and all wastewater removal.
- Draining other sewage water.
DO NOT USE THE PUMP IN PONDS, SWIMMING POOLS, BATH TUBS, OR ANY OTHER AREA
WHERE THERE ARE PEOPLE; SERIOUS ACCIDENTS CAN OCCUR.

Notice to installing contractor: Instructions must remain with installation.
GENERAL INFORMATION
These models are complete systems used in sewage or dewatering installations with
sideoutletangedpumps.Theycanbeusedinbasinsof1Oftdepth(fordeeper
depths, consult factory). The guide rail systems are particularly useful when the liquid
level is above the pump discharge pump. The systems feature easy automatic engage-
ment and disengagement for removing the pump for service or repair without draining
the basin.
GENERAL CONSTRUCTION
Aanged discharge elbow base is supplied with the rail system. The elbow base has
casted mounting pins which supports the lower rail guides. The elbow base, mounting
plate, as well as the upper guide rail bracket are made of durable dass 30 cast iron
that is epoxy coated. All models require the use of 1’’ schedule 40 (galvanized steel or
stainless steel) pipe for guide rails. Pipe is furnished by the installer.
LIFTING CABLE
The pump is equipped with lifting lugs that are an integral part of the motor housing or
cover for lifting. A permanently attached chain or cable (purchased separately), should
be used to aid in pump installation and removal. It is not necessary to use a separate
pullchainonthemountingplatewhichisboltedtothepumpdischargeange.
UPPER GUIDE RAIL SUPPORT BRACKET
As mentioned above, all the rail systems utilize 1’’ standard pipe for the guide rails.
The upper guide support rail bracket is to be mounted to the basin cover frame, as per
the discretion of the installer.
INSTALLING RAIL SYSTEM PARTS (Concrete Basin)
Discharge Elbow Base and Guide Rails:
1 . Lower the elbow base into the basin.
2. Position the elbow base by dropping a plumb line from the center of the guide
rail pins located on the upper guide rail bracket to the center of guide rail pins
 protrudingfromtheelbowbase.Leveltheelbowbaseangeintwodirections
90° to each other. Mark the outline of the base and bolt holes/slots on the
 concretebasinoor.
3. Move the base aside to allow for installation of 1’’ mounting bolts (not included &
method of installation to be determined be installer). Secure base with mounting
bolts.
4. Cut the 1’’ pipe guide rails (supplied by others) to the proper length and install
them between the pins of the upper guide rail bracket and the pins on the elbow
base. It is recommended that the guide rails are to be 1’’ schedule 40, galva-
nized or stainless steel pipe.

INSTALLING RAIL SYSTEM PARTS (Fiberglass Basin) Discharge Elbow Base,
Discharge Piping and Guide Rails:
1. Determine proper length required for discharge piping.
2. Connect discharge piping to elbow base.
3. Lower the discharge piping/elbow base assembly into the basin.
4. Position the elbow base by dropping a plumb line from the center of the guide
rail pins located on the upper guide rail bracket to the center of guide rail pins
 protrudingfromtheelbowbase.Leveltheelbowbaseangeintwodirections
90° to each other.
5. Cut the 1’’ pipe guide rails (supplied by others) to the proper length and install
them between the pins of the upper guide rail bracket and the pins on the elbow
base. It is recommended that the guide rails are to be 1’’ schedule 40, galva-
nized or stainless steel pipe.
ATTACHING MOUNTING PLATE TO PUMP
1. Determineifmountingadapterange(included)isrequiredforproperassembly.
2. Positionmountingplateagainstpumpdischargeangeor(ifrequired)sandwich
 mountingadapterangebetweenmountingplateandpumpdischargeange.
3. Secure mounting plate to pump with screws and washers. Tighten securely.
INSTALLING PUMP AND DISCONNECT
Position pump so the guide rails are captured by the mo unting plate. Slowly lower the
pump down the guide rails to the base.
If the pump is supported from beneath with concrete blocks or extended legs on the
pumpbase,makecertainthemountingplateissufcientlycompressedforsealing.
The cantilevered weight of the pump is required for compressing and sealing the ma-
chined faces between the mounting plate the elbow base.
After lowering the pump down the guide rail, secure the upper end of the lifting cable
where convenient, to prevent the cable from falling into the basin.
