Centrifugal pump

Screw pump

1. There is a three-phases brushless motor built in the pump, who directly drives a screw (for a

screw pump) or a turbine (for centrifugal pump) and has passed a special control test.

2. The motor is with simple and reliable construction, small volume and small weight.

3. The special double-plastic technology for motor encapsulating makes it suitable to be used

under water, as its insulation resistance exceeds 500 MegaOhms. The motors' bearings are

water-lubricated, which excludes a need of other lubricating materials (such as oils and

greases), which might be thrown in the water. This protects the environment.

4. The controller is especially designed to work with this type pumps, supplied trough photovoltaic

modules as it has built in МРРТ (maximum power point tracker), which moves the pannels

working point and as this extracts the maximal possible power. The built in protections from

short-cut, over-voltage and overheat protects the controller as well as the pump from damages.

IV. Guidelines for installation and exploitation of solar pumps

Photovoltaic module (PV) selection

1. Operating principle:

The photovoltaic module converts the solar energy into electric energy (DC) → DC electric

energy enters into the controller → the controller stabilize the voltage, charges the accumulator

(option only for model 3TSS1,38) and produces voltage that conforms the pumps motor → the

pump extracts water

2. Solar pump system's advantages:

a. Much easier and more widely used than any other electrically driven pumps

b. Economic and environment friendly, because of renewable energy source usage.

3. Photovoltaic module(s) and accumulator selection

a. The PV module power is necessary to be selected in a way of being 30% or more than the

power consumed by the pump. The PV voltage must comply with the pumps' operating voltage

and the maximal voltage of the controllers' inlet.

b. The number of the accumulators used depends from the selection that we made about the

accumulators' voltage and the voltage of the pump. The voltage needed for a certain pump is

formed trough serial connection of the accumulators. The accumulators capacity should be

selected in accordance with the pumps' power and the time during which the accumulator can

supply the pump without being discharged under the threshold. It is not recommended to

connect accumulators in parallel connection to increase the total capacity, especially in

the cases when the accumulators are with different capacity!!!

* if 2 or more PV modules are to be connected – please pay attention about the way of the connection
A. If you connect 2 or more PV modules in series, the voltage in the 2 ends of the circuit will be equal to

the voltage of one module multiplied with the panels number, and the current will be equal to the current
of one module.
B. If you connect 2 or more PV modules in parallel, the current of the whole circuit will be equal to the
current of one module multiplied with the modules number, and the voltage will be equal to the voltage
of one module.

C. The connection of photovoltaic modules with different parameters is not recommended!!!

Sequence of solar pumps installation

Open the package and check the product entirely

The control switch must be in position ”OFF” (“0” position)

Connect the photovoltaic module(s), accumulator (only if used in the relevan case), pump and

level sensors cables to the cable terminal of the controller in agreement with the connection
scheme. Choose the right cable dimension, fuses, switches and water level sensors.

Tight the fixing screws at the cable terminal with a screwdriver.

Be sure that the photovoltaic module(s) deliver power enough to the controller.

After finishing the upper steps, switch on the control switch (position I), the motor will operate for

10 seconds, after that will stop for 30 seconds (self-test), if the cables and the installation are
right, the pump will restart and work without interruption.

If the pump doesn't work properly, please check the operating indicators and the fault

indications, to find the reason and contact the supplier.

Mount the controller in a dry and well ventilated place. Never expose the controller in outer

atmospheric effect – the controler is not waterproof, and this will lead to its damage.

!!! Notes

The pump must be immersed in the water 15-20 minutes before its first starting. DO NOT

START THE PUMP DRY!, not even for test switching on. The working depth should not be
under 0,5m. It is not recommended the installation of the pump in depth bigger than 20m
under the water level.

During the installation of the submersible pump, there must be a rope connected to it.

Don't lift up the pump through the electric cable, the warranty will be refused if it gets
damaged.

The motors' supplying cables (U,V,W), must be connected to the controllers' cable

terminal (U,V,W) in the right way. Otherwise the motor will reverse and the pump will not
extract any water or very little water.

The water level sensor should be put over pumps' suction level. Otherwise it won't be

able to prevent the pump running dry. If there is no need of level sensor installation,
terminal WH and terminal WC (COM1) should be shortcut-connected.

You must make sure that the pump is positioned on the right depth. The stopping

between the switches ON and OFF should be at least 3 minutes or the pump protection
will be activated and the pump will stop working.

If there is a need of controllers' parameters change, the cover should be opened very

carefully to prevent the interruption of the inner connections.

15

When a screw type solar pump will not be used for a long time, please take it out of the

water, wipe the housing and the screw and oil the pump housing with vegetable oil.

The regulating bolt at the base is already set by the quality control before the delivery.

The turning of this bolt by the customer might cause defects, degradation or low
efficiency.

The submersible pumps can be used only in waters with sands less than 0.1%.

The supplying cables cross section shouldn't be less than 2.5 mm2. It should be chosen

in agreement with the cable length and the pumps' capacity.

The pumps' supplying cable can be elongated depending the working deep, as the

connection place should be very well insulated to prevent a shortcut danger and damage
in the controller. The connection and insulation method is shown on picture 1, page 16.
Peel the outer cable covering as well as the covering of the separate wires, as they
should be cut in different length as it is shown on the picture. Connect the three wires,
tight the connections with thinner not insulated wire and weld the connections. Every
separate connection should be insulated with thermal shrink hose. The three
connections are tightly twined with insulation tape and over the tape is put thermal
shrink hose. Make sure that the thermal hose is well stuck and water can not enter from
anywhere. Finally join the three wires to the controllers' terminal as observing the
polarity (U,V,W).

!!! Notes

1. Important for water level sensors:

If the pump works over the water level, there is a danger of pump damage (the warranty is invalid).

16

The level sensors' target is to protect the pump from running dry while monitoring the water level and if
necessary sending a signal to the controller to switch off the pump.

The level sensors are three probes from a stainless steel. The probe should not be covered or to
touch conductible parts, so it can work properly.

If it is necessary to elongate the probes' cable, the cable which will be used must be with
suitable cross section, the connection should be welded and insulated with insulating tape and
thermal shrink hose.

2. Level sensors installation:

The cables of the three probes of level sensors must be connected to WH, WL and WC separately.
“WH” probe is installed in upper position to detect the water level in which the pump shoul start if it was
stopped because of water level fall. “WL” probe is installed just over the pump, to detect the water level
where the pump wouldn't run dry. “WC” probe /common point/ is to be installed under the pump level.

Level sensors' working range is between probe “WH” and probe “WL”. When the water level is

lower than probe “WL”, the pump motor will stop working. When the water level raises up to

probe “WH”, the pump motor will start working again. Be careful for the distance between WH and

WL, it must be selected in such way, that the water level to raise for not less than 3 minutes.

VI. Cleaning and maintenance of PV module

Crane Ltd modules are manufactured as this to have prolonged service life and require minimal
maintenance.
You should regularly remove accumulated dirt from the PV module(s) (eg dust, pollen,
vegetation, bird droppings, etc.). Such contamination, which overshadows the modules' active
areas can lead to limitation of system performance and decrease the solar pump production.

Please obcerve the following points:

For PV module(s) cleaning use water and soft sponge.
Avoid the water cleaning, when there is a danger of freezing of big temperature

differences between the module, the water and the air.

Hard water used for the cleaning, must be descaler in advance, so the remaining traces

to be avoided. Remove the remaining water from the module.

Do not use abrasive cleaning materials or surface-active agents (eg. Soap). Do

not scrap the contaminations. This might damage the modules' surface.

VII. Protection of the environment

After the service life termination of the solar pump, do not dispose it with normal
household waste, but transmit it to a collection point for waste recycling. This will
help protect the environment.

IMPORTANT INSTRUCTIONS

Solar panel position:
As we use the electric energy from photovoltaic pannels for the solar pump supply, is
necessary the right solar pannel orientation regarding the sun. The photovoltaic module have
highest performance when the solar energy falls perpendicularly regarding the pannels' surface.
Every shading guides to photovoltaic pannel performance decrease, and there from, to
decrease of the pumped out water flow.
