6. ASSEMBLY / INSTALLATION
6.1.Connection Type
i. Suspended Connection: The pump is hanged to the inlet of the pipe
system on the ground by a special connecting device. Pump does not
sit on the base of the sump. If required, the connection elbow can be
used as a non-return valve. Steel discharge pipe between the pump
and suspension part keeps the pump on suspension. Suspended
connection can apply on 50-160, 50-200 (up to 5,5 kW) and 80-190
types.At suspended connection option,it should be noted that these
pumps enables to operate more reliably by not bringing overload to
the discharge pipe because of being lighter.It is not necessary for
sump bottom to be flat and solid for suspended connection.
Suspension elbow and complete suspension set are needed for this
application.
Figure 3 - Suspended Connection

Mas Grup

ii. Hose Connection: In this kind of application the pump is sat on the
base of the sump. In this application the bottom of the sump should be
flat and solid (in order to make the pump not to sink but to stay
vertically). The pump is put down to the sump and uplifted by means of
a chain. For ease of assembly and disassembly, should be used the
flexible hose as a discharge pipe. Water is pumped up to the surface by
a flexible hose and can be connected to a pipe system if necessary.
Necessary auxiliary parts for this application: Hose connecting union,
elbow, sit-on-foot and riser chain.
Figure 4 - Hose Connection
iii. The Automatic Coupling System: This application easily connected
and removal of the pump to the installation is to provide an improved
system. It is not necessary doing some operations such as emptying
the sump, where the pump is, and installing and uninstalling bolt, etc. to
make the pump flange-pipe connections during the coupling.
Figure 5 - The Automatic Coupling System Part Numbers
1.Carrier Elbow: It is a special strong and broad-based elbow which
placed to the sump base before starting up. This elbow carries the
weight of the pump. Therefore it must be assemblied very stable to
sump base.
2.Slideway: It consists of from two parallel pipes. It is connected to
the carrier elbow from the bottom. When lowering down the pump
acts as guide. Length is set according to the depth of the tank in
place.
3.Coupling Hook: It is a carrier special part, which is connected to the
discharge flange of the pump.
4.Special Coupling Gasket: It is a rubber gasket, which located in the
coupling hook. Through special shape, it prevents water leakage by
expanding while the pump is running.
5.Carrier Chain: It provides to dip the pump to the water. It is given
with all ENDURO type pumps.
Operation of The Automatic Coupling System
1. When suspended from the rear
suspension hole pump stops
inherently slightly tilted. In this case,
the hook is passed to slideway.
Figure 6
2. The pump is slid down in inclined
state.
Figure 7
3. When the special slots of the
hook contact carrier brackets on
the elbow, scrolling of the pump
stops. Carrier chain is still tense.
Figure 8
4. When the carrier chain has been
released, the weight of the pump is
loaded to the elbow via hook. The
press of the pump’s weight to the
elbow, provides the gasket pressed
against the elbow. When the
pressure occurs in the pump, gasket
prevents water leakage by
expanding.
Figure 9
It is adequate the pump is pulled out from the chain for dismantling.
Installation of the carrier elbow and the discharge pipe are required when
the sump is dry (during construction). In case of this installation make
subsequently, the system mat not be strong enough.

6.1.Electrical Connections
6.1.1. General
All electrical works must be done by qualified electricians. All main
electrical equipment must be earthed. Failure to heed this warning may
cause lethal accident. Make sure that the earth lead is correctly
connected by testing it.
Use MASDAF RLE-1C Motor Protection and Control Relay which is
supplied with the pump. We do not guarantee the pumps running
without RLE-1C *
Motor Control Panels must be manufactured according to the circuit
diagrams in this booklet. If you use a different circuit diagram, please
contact our technicians and have their approval.
Make sure the currents and cable diameters of contactors, overload
relays and fuses are suitable for motors nominal currents.
Check the mains voltage and be sure it corresponds to the value on
motor label.
Check the connection of motor cable socket and secure the tightness
before initial operation.
Connect the energy and control cable to the motor control panel
complying with the colors and diameters stated in the diagrams.
Make sure the outer cover of the energy cable is protected against
damages that might be caused by sharp metal or concrete corners and
prevent it from being squeezed in narrow spaces.
Do not use the energy and control cable to lift the pump.
*It is not valid, in cases where the panel is supplied with the pump by
MAS DAF MAKINA SANAYI A.Ş.
6.1.2. RLE-1C Motor Protection and Control Relay
MASDAF RLE-1C Motor Protection and Control Relay is very important
part of ENDURO Series submersible sewage pumps. It is supplied with
the pump and it shall be used to secure smooth operation of motor and
the pump.
When the device is switched on, all indicator lights blinks in order and the
control unit makes a self-check. If there is not any failure, NORMAL
indicator light switches on in green indicating it is ready to run the motor.
Water Leakage: In case of water leakage into the motor casing or oil
chamber, red indicator light switches on and the relay shuts down the
motor. Alarm relay becomes activated and until the RESET button, which
located on RELAY, is pressed, alarming goes on by blinking of red
indicator light in short periods. In this fault, if the RESET button is not
pressed, motors is not stepped in. In this case, must do maintenance by
removing the pump and repair the case of water leakage. The sign by
blinking continues until you press the RESET button. When RESET
button is pressed, the lamp goes out and alarm relay is deactivated.
Overheat: In case of overheating of motor windings, in which the
temperature exceeds 130°C, the red indicator light switches on and the
relay shuts down the motor. Indicator light blinks in short periods at
alarming position. When motor has cooled down, relay restarts the motor
while alarming goes on until the RESET button is pressed. Pressing the
RESET button disables the alarm relay and indicator light stops blinking.
Overload: The relay shuts down the motor, if the current overload limit is
exceeded. Alarm relay becomes activated and until the RESET button,
which located on RELAY, is pressed, alarming goes on by blinking of red
indicator light in short periods. As the failure is fixed, pressing the RESET
button will disable the overload and the alarm relay, so the system turns
back to normal conditions.
Maximum Level: When water level reaches the maximum level, which is
set by the user, float switch sends on alarm signal. MAX yellow indicator
light starts blinking. This alarm does not affect the current state (run or
stop) of the pump. Pressing the RESET button disables the alarm relay
and indicator light stops blinking. When RESET button is pressed, the
lamp goes out and the alarm relay is deactivated.
Phase Failure: An external phase protection relay, mounted in the
control panel, is connected to RLE-1C for checking phase sequence and
phase failures. When there is a failure in mains voltage or in phase
sequence, the motor is shut down by the relay and red indicator light
starts blinking. By the time the failure is fixed, the motor restarts
automatically while alarming goes on until the RESET button is pressed.
When RESET button is pressed, the lamp goes out and the alarm
relay is deactivated.
Ready By the time all red indicator lights on RLE-1C switch off, green
indicator light switches on, meaning that it is ready to run the motor. In
case of failure, green indicator light switches off and the relay shuts down
the motor.
Figure 10 - RLE-1C Motor Protection And Control Relay
6.1.3. Control Panel
The control panel is designed in order to safer operation of ENDURO
submersible pump can be claimed as extra. Single-pump or the 2 and 3
pump groups can be operated by the control panel.
In the pump operating principle of a multi-pump panel, all pumps can be
operated simultaneously or as a backup.
The control panel is in protection class IP 55 and it is isolated from dust,
splashing water and wastewater environment gas. Short circuit protection,
phase failure and protection against phase sequence, thermistor
protection, water leakage protection, over current protection, the indicator
lights, manual-automatic paco, start-stop as manual and the main switch
equipments are available control panel.
Floater is included in the package of submersible pump.
When the pump is supplied with control panel, there will not need a relay.
In this case the control panel will make the protection task of the motor.
When the pump is supplied without control panel, relay is sent with the
pump.
CAUTION
If the control panel is not supplied from our company, MAS DAF
MAKINA SANAYI A.Ş. is not responsible for the malfunction

connects have to be fixed by licensed electricians.
CAUTION
Do not start your pump dry ( WITHOUT WATER )
7.1. Checking The Direction of Rotation
CAUTION
All types and of ENDURO Series Submersible Waste Water and Sewage
Pumps rotate in clockwise (CW) direction viewed from the top. If all the
electrical connections are done according to the instructions, the pump
will rotate in the right direction. However, it is strongly advised to check
the direction of rotation before installation of the pump down in the sump.
To check the direction of rotation, while the pump is suspended in the air,
first press the start button and then quickly press the stop button.
Although the impeller cannot be seen, direction of the casing’s reaction
can be observed.
There are 3 situations;
1.If the reaction of the casing is in Counter Clock Wise (CCW), the
direction of rotation is correct (CW). Electrical connections are done in
the right way. Pump can be installed to the sump.
2.If the reaction of the casing is in clock wise (CW), the direction of
rotation is incorrect (CCW). To fix the problem, the position of two motor
cables to the panel must be exchanged. Please recheck the direction of
rotation after exchange.
3.When the start button is pressed, if the contactor on the panel is not
energized, PHASE FAILURE light is blinking and the motor is not
running, whether there is a phase sequence failure or one of the
phases is not energized. Make sure that all three phases one
energized. Then, check for the phase sequence. The correct sequence
is to be set according to direction of rotation.
7.2. Start-up Procedure
When the control panel is energized, make sure that sure that green
indicator light (NORMAL) is switched on. This indicates there is not any
failure and the electrical connections are done in the right way. Pressing
the START button or increasing of water level to the set level will start up
the motor.
7.3.Shut Down Procedure
The motor can be shut down manually by pressing the STOP button. The
motor will also automatically stop when the water level drops below the
minimum set level. If another application will be used instead of Level
Controlled Automatic Starting System, please have MAS DAF MAKINA
SANAYI A.Ş.’ s approval for changed electrical diagram. MAS DAF
MAKINA SANAYI A.Ş. refuses to assume any responsibility if the pump
used for different applications without prior written permission.
8. MAINTENANCE
CAUTION
Maintenance operations must be done by authorized personnel with
protective clothing only. The personnel must also beware of high
temperatures and harmful and/or caustic liquids. Make sure that the
personnel reads carefully the manual.
The instructions in Safety Precautions must be executed during
maintenance and repair
Continuous monitoring and maintenance will increase the engine’s and
pump’s lives.
8.1.The Checks During The Operation
Pump must never be operated without water.
Pump must not be operated for a long time with the discharge valve
closed (zero capacity).
All the auxiliary systems must be in use while the pump is operating.
If the system consists of a substitute pump, keep it ready by operating it
once a week. Check also the auxiliary systems of the substitute pump.
8.2.Mechanical Seal
Mechanical Seals are absolutely leak tight and needs less maintenance
than soft packing.
1.Provides leak-proof operation in heavy operating conditions (in waste
water pumps, chemical process and refinery pumps).
2.Easily mountable and needs less maintenance.
3.Does not cause wearing on the shaft
4.Sealing operation does not depend on the quality of shaft finishing.
Lay down the motor at which one of the two oil plugs is upside and the
other is downside.
Open oil plugs and empty the oil into a clean pot.
If the oil is clean and clear, it means the mechanical seal is in good
condition. The same oil can be used again.
If the oil is in yellow-gray color or it is mixed with water, it shows the
mechanical seal is worn out and it needs to be changed. In this case the
WATER LEAKAGE light will be off on the motor control panel and the
motor will stop.
If the results of these four stages are positive, you can take down the
pump into the sump.
8.3.Auxiliary Components
Check regularly the fittings and the gaskets, replace the worn out pieces.
