2. SYMBOLS AND WARNINGS
WARNING
WARNING
The power supply cable should never be used to carry or shift the
pump. If damaged, it must be replaced with a cable of similar
specication.
Before commencing installation ensure equipment is well
protected and the power supply has been switched off.
WARNING
The power cable should be provided with short circuit protection
(MCB) to guard against high frequency currents faults. Ensure
that the earthing complies with the required local standards.
WARNING
The pump is supplied with grounding wire. To reduce the risk of
electric shock, ensure that the pump is properly grounded.
WARNING
It is not recommended to use RCD (Residual Current Device) with
variable speed drives/motors. However, if mandatory, use Type B
because of the nature of the constant DC leakage current.
The electrical connections should be carried out in accordance
with local regulations. Ensure that the values indicated on the
nameplate match with the supply voltage and frequency.
WARNING

WARNING
During both the rst installation and maintenance the POWER
in the supply line should be switched off.
ŸEnsure that the pump is mounted in a level position on the base plate, with an
inclination angle not exceeding ± 5°.
ŸAttach the pump securely to a stable, level base by utilizing screws inserted through
the openings in the base plate.
Fig 3
Fig 2Fig 1
WARNING
For emergencies and maintenance, the pump must be easily
accessible.
WARNING
The pumps must be installed in a dry position and protected
from the elements by means of a suitable cover.
NOTE
As advised on dimensions table, enough space for service and
maintenance access should be considered.
WARNING
The pump can be installed indoors or outdoors.

8
ŸTo prime pump, add water to the priming plug until it overflows.
ŸWhen installing the water pump, avoid use of soft rubber pipe, due to risk of
collapsing.
ŸThe foot valve shall be vertical and installed 30cm away from the bottom of the water
to avoid drawing in of sediments.
ŸAll connections of the inlet pipeline must be sealed to minimize elbows, otherwise
suction may not be effected.
ŸThe diameter of the water inlet pipe shall be at least the same as that of the pump inlet
to prevent hydraulic loss from affecting the water outlet performance.
ŸWhen using the pump pay attention to the water level drop and ensure the foot valve is
not exposed above the water surface.
ŸWhen the length of the water inlet pipe is more than 10m or the lifting height of the
water is more than 4m, the diameter of the water inlet pipe must be greater than the
diameter of the pump inlet.
ŸWhen installing the pipeline, make sure that the pump is not under pipeline pressure.
ŸIt is advisable to install a strainer when source water is suspected to be dirty.
ŸThe outlet pipe diameter shall be at least the same as the outlet diameter to minimize
the pressure drop, high flow rate and noise.
ŸWhen the water pump is installed in a place that may be flooded ensure to install a
raised platform to prevent the ventilation holes from being flooded.
ŸWhen installing the pump, ensure to eliminate any air locked within the pipeline.

4. OPERATION
Priming the pump
To start the pump, it is necessary to prime it by filling with water. Do not start the
pump until it has been filled with water.
ŸUnscrew the priming plug and allow an even flow of water.
ŸScrew the plug on again. The pump is now ready to start.
Starting the pump with control panel
ŸTo prepare the pump for venting, open a tap.
ŸInsert the power plug into the socket and turn on the power supply. The pump will
power after 3 seconds after main power is introduced.
ŸClose the tap once water flows.
ŸOpen the highest tap point in the installation, such as a shower.
ŸUse the buttons to adjust the pressure set point to the required pressure.
ŸOnce done, close the tap.
To set pressure
ŸThe pump's water pressure can be adjusted to any value between 1.5 to 6.0 bar
and 7 bar for DSmart 1500.
ŸThe default pressure, as indicated is 2 bar which for most applications is sufficient.
The difference between inlet pressure and outlet pressure must not exceed 3.5
bar. For example, if the inlet pressure is 0.5 bar, the maximum outlet pressure
should be 4 bar.

Notes:
Pressure mode:
The indicator displays the operating pressure and set pressure. To adjust the pump's pressure,
press the button. The pressure can be set within a range of 1.5 to 7.0 bar.
Speed mode:
The indicator displays the running speed (r.p.m). In this mode, the pump does not stop
automatically. To adjust the pump's speed, press the or button. The speed can be set within
a range of 2,500 to 5,200 r.p.m.

Indicator buttons:
ŸPump is ‘ON’.
ŸLeakage detected in pipeline: Check where the leakage could occur or contact nearest
Dayliff retailer.
ŸVoltage protection: Input voltage has fallen out of specification for pump. Contact nearest
Dayliff retailer.
ŸDry run detected: Refer to section 6: common fault codes and troubleshooting list “error
codes E10.
Dry Run Protection
This pump is provided with dry run protection, which includes a safety control circuit that can
detect when the pump experiences water storage. If the pump runs out of water, it will stop as
part of a protective logic sequence. Before restarting the pump, ensure there is enough water
supply and all terminal fitting outlets are closed.
In case of water shortage and uninterrupted power supply, the pump controller will initiate a
protective logic sequence.
WARNING
The pump will stop operation when it detects water shortage and
will remain off for 5 minutes. The pump will then run two times the
same sequence. If the water shortage still remains, it will stop
operation for 6 hours before attempting to start again.
Maintenance in Operation
ŸThe inlet pipe must be full of water. The pump should not be operated without water.
ŸRegularly check the motor current, which shall not exceed the rated current of the motor.
ŸAfter long term operation of the pump, due to mechanical wear, the noise and vibration of
the unit may increase, leakage may also occur and the performance compromised. At this
point, the pump should be shut down for inspection.
5. MAINTENANCE
12
Note
ŸPressure mode is set as default.
ŸSpeed mode be activated only when pressure sensor fails. Speed mode ensures that the
pump operates temporarily for water usage
WARNING
The fewer the lights are on, the more energy is saved.
ŸPress reset button for 3 seconds to reset all parameters back to the default.
ŸIncrease set pressure or running speed by pressing .
Decrease set pressure or running speed by pressing .
WARNING
In speed mode, the water pump does not stop automatically.

Mechanical Seal Maintenance
ŸThe mechanical seal lubrication shall be clean and free of particles.
ŸBefore starting, turn the motor severally to prevent the graphite ring from breaking and
damage due to sudden starting.
ŸThe seal leakage tolerance is 3 drops/min, otherwise, it should be repaired.
ŸWhen repairing and assembling the mechanical seal, avoid contact with oily substances
and use soapy water instead to lubricate and reduce resistance.

E1
Pa n e l a n d m o t h e r b o a r d
communication failure
Check whether the panel cable is well connected, and try
plugging and unplugging again. If it cannot be resolved. The
panel or motherboard has failed and will need replacement.
E2 Stall Try to turn the fan blade to see if the impeller is stuck.
E3 Voltage failure,  icon lights up Check voltage.
E4 Outlet pressure sensor failure
Check whether the lower pressure sensor interface is in poor
contact and re-plug. If still unresolved, replace the pressure
sensor.
E5 Controller failure
• Power off, wait for the panel light to go out, then power on
again.
• If still unrecovered, the motor or driver board is damaged
and may need to be replaced.
E6 Loss of phase
Check whether the motor cable is connected measure the
resistance of the motor wire and check if there is any
discontinuity.
E7 Overcurrent
• Check if there is a short circuit in the motor.
• Check the voltage resistance of the motor to see if the
voltage resistance is enough.
• Re-power and test if the motor is ok, the starter may be
damaged due to accidental impact.
E9 Water temperature protection Check whether the water temperature is abnormal.
E10 Lack of water,  icon lights up
Check whether the water is available.Enter the factory menu to
adjust the water shortage pressure and adjust it to the current
