Solar array direction and elevation adjustments as shown in Fig6.3,first to adjust the light receiving horizontal area

face the direction of the sun at noon, then let the sun light (at noon) perpendicular to the light receiving area.

Fig6.3

The scientific method is: according to the actual local latitude and checking longitude, by checking table and actual

geographical situation calculate the horizontal installation direction and elevation, then install based on those

parameters.

warning

Unreasonable direction and elevation will reduce solar energy utilization ratio, thereby reduce

the efficiency of the system.

The elevation should change with the seasons and adjustment, especially in the high latitude

region should adjust the elevation angel to achieve the maximum solar utilization ratio.

hoisting hole and fixed by chunk (as shown in Fig6.6). Another end of hoisting cable is fixed to the derrick reel

or fixing device.

Fig6.6 hoisting cable installation

b) According to the actual situation prepare long enough waterproof 3 core cable( cable specifications with

reference to cable selection guide chapter),Let the cable head and pump lead line respectively pass through

the waterproof connector of water proof junction box and dock. And remark the U V W 3-phase identification

on docked waterproof cable. For more details please see under water connection guidance chapter.

c) Prepare a suitable water pipes to meet real needs( note the nominal pressure of the water pipes and pipe

fittings should be greater than the actual working pressure).Wind the outside wire connector with plastic

stripe then screw it into the outlet of water pump and connect.

d) Extend the cables of probe-type sensor or float sensor to appropriate length, underwater joint processing can

consult pump cable processing method. For more detailed mounting method please refer to the “water level

sensor installation guide” chapters.

e) Strap the connected cables of sensor and water pump on the pipeline at regular distance intervals。

f) Hold up the pump and pipeline and pull them slowly into the well through the hoisting cable, when the pump

to the appropriate height, please fix the hoisting cable to the manhole cover or the corresponding fixing

device.

g) Connect the ground water supply pipeline with pump outlet pipeline. This pump installation is complete, thenext step for the electrical installation and debugging.

Warning

The steel wire rope tensile strength must meet the actual demand, or pump has falling damage!

Underwater wire water-proof treatment must be reliable, or it may cause water level judgment

errors and machine burn out.

Can’t use water pump connecting cables or pipe to lift pump, or it may cause: water pump fall

well, machine damage and unpredictable accidents.

The steel wire rope fixing device must be safe, reliable, or pump has falling damage risk!

6.4.4 water level sensor installation guide：

a) Controller can pick up 2 channel water level sensor, that the source (well, rivers, lakes and so on) water level

and water-filled water level sensor. Source water level sensor used to test whether water source is dry, prevent

pump anhydrous idling and damage. Water-filled water level sensor used to check the high cistern or water

tower is full filled with water or not, prevent water overflow waste. Source water level sensor is suggested to

install, or motor would be damaged! Water-filled water level sensor according to the actual situation to decide

whether or not to install.

b) Water level sensor has a variety of specifications ，this handbook lists only floating ball type and probe type

water level sensor. Note: The well diameter less than 8 inches cannot use float ball type sensor, must use the

probe-type sensor.

c) Source water level sensor installation: a, the float sensor installation as shown in Fig 6.10 , the float sensor

suitable for wide surface water, diameter less than 60 CM wells can not be applied. B, the probe type sensor

wiring way (Fig 6.11).

Note: Dry water protection water level should be higher than the water outlet of the water pump, and the

before restart to work, please assure the water capacity is enough for pump to work at least for 5 minutes.

6.4.5 under water terminal guidance：

a) Ordinary water and rive water usually have a low impedance electrical conductivity, and the cables of water

pump and sensors are too short to meet the actual demand, so when the cable joints immersed in water, wire

connection is needed to do waterproof treatment to avoid electric leakage accidents.

b) Connection method ： Let the cable head and pump outlet line respectively pass through the junction box

waterproof connector and skinless butt, remark the U V W 3-phase logo in docking waterproof cables ,do

insulation treatment with electrical tape and waterproof tape , then thread finishing into the junction box,

6.4.6 The wiring matters needing attention：

a) Please follow cable selection table recommended cable diameter. Other standard cable models please

conversion or query the corresponding cable parameters table, and the prerequisite for effective conductive

load area is not less than the recommended value. All the reference data in the table is based on the effective

conductive cross-sectional area unit.

b) The wire connecting controller and pump can not be connected to the capacitor or surge absorbers, otherwise

it will cause the system often protected or even damage.
