5. Aquae viscus profunditas aquae sentinae non minus esse debet quam 1-1.5 metra a gradu aquae dynamicae ad nodi aquae diverticulum (vide Figure 2). Alioquin aquae sentinae gestus facile laedantur.
6. Aquae levare sentinam nimis humilis esse non potest. Alioquin valvae portae aquae putei fistulae inaugurari debet ut fluere sentinam fluere apud punctum aestimatum fluere prohibeat ne motor oneretur et exuratur propter magnas rates fluxus.
7. Cum aqua currit sentina, aqua output continuum et par esse debet, currens sit stabilis (sub condiciones operationis aestimatae, plerumque non plus quam 10% currentis aestimatae), nec vibratio nec strepitus esse debet. Si qua deprauatio est, machina cessari debet causam cognoscendi et removendi.
8. Cum inaugurari, attende ad occasum filum fundationis motoris (vide Figure 2). Fistula cum aqua est ferrea tibia, a puteo fibulato duc; cum fistula aquatica fistula plastica est, eam a fundamento sentinae electrici notam duc.

1. （1）After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon. If everything is normal, it can be put into operation.
2. （2） After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. （3） After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing the motor to burn out due to excessive current.
4. （4）After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, running current and insulation resistance are normal.If the following conditions are found, the pump should be shut down immediately to eliminate the fault:
5. 1 under the rated working conditions, the current exceeds 20%;
6. 2 the dynamic water level drops to the water inlet part, resulting in intermittent drainage;
7. 3 the submersible pump vibrates seriously or emits huge noise;
8. 4 the supply voltage is lower than 340 volts;
9. 5 a fuse is blown out;
10. 6 the water pipe is damaged;
11. 7 the thermal insulation resistance between the motor and the ground is less than 0.5 megaohm. The discovery of these problems need to be handled in time to ensure the normal operation of the pump, improve its reliability, so as to ensure the stable operation of the equipment for a long time.

（5）unit disassembly:

 1 untie the cable tie, remove the pipeline part, remove the wire plate.

 2 cochleae aquam fulmine deprime, aquam in camera motoria pone.

 3 remove the filter, loose the fixing screw on the coupling to fix the motor shaft.

 4 screw down the bolt connecting the water inlet section with the motor, separate the pump and the motor (pay attention to the unit cushion when separating, prevent the bending of the pump shaft)

 5 pump disassembly sequence is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, avoid bending the pump shaft and each part in the disassembly process.

 6 motor disassembly process is: (see figure 1) place the motor on the platform, and remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn. Then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and the upper guide bearing seat.

 7 unit assembly: Before assembly, the rust and dirt of the parts should be cleaned, and the mating surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.

6. The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should be replaced.

 I, aquam in cavo motorio extingue (praesertim hieme ne motor a frigore) et funem bene ligaveris.

 2, repone in cella involucri sine substantiis et vaporibus corrosivis, cum temperatura infra 40 °C.

 III, diu terminus usus observandum ne rubigo soleatus submersible.
