and understand the instructions before the first application.
2. The users shall obey all safety instructions. Otherwise, you and others may
suffer from injury.
3. You shall preserve all application and safety instructions for the further
reference. The equipment shall be used when it has normal functions.
4.Please use the equipment according to the safety and technical
requirements as specified in the instructions.
5. The semi-stationary and static form of the equipment is designed to be
transferred to the house and garden: Spray water and make watering.
6. The equipment shall be used within its performance range. Please don’t
use the equipment which has abnormal switch.
7.The equipment is prohibited to be used for providing water or conveying
food.
8. Please don’t use the equipment in the room which contains the
inflammable and combustible liquid or gas.
9. When the components which fail to be tested and recognized by
manufacturers are improperly used, the equipment is likely to suffer from
the unforeseen damage.
10. Any application which deviates from the intended purpose as specified
in the instructions will be considered as the unauthorized application, as a
result, the generated problems are independent of the manufacturers.
11. Please ensure that the closed equipment will not be started again by
mistake.
12. The equipment shall be connected to the socket which has correct
installation and grounding.
13. The fuse wire shall serve as the current circuit breaker when the residual
current exceeds 30mA.
14. Please ensure that the power supply can satisfy the connection
regulations before the equipment connection.
15. Please don’t bend, extrude, pull or drive the power wire to avoid the
related dangers caused by line breakage.
16. Please check the plug and power cable before application. When the
power cable has been damaged, please disconnect the plug immediately.
Please don’t use the equipment which has damaged power line.
17. When the equipment is idle, please ensure that the plug has been pulled
out. Meanwhile, the equipment has been closed, then, unplug the power
supply.
As for the fixed application, please apply four screws to tighten the
equipment on the foundation support firmly.
When the equipment is used for the pound and swimming pool in the
garden, the equipment shall be subject to the special setup to avoid the
overflow and falling.
The equipment shall be installed in the well-ventilated places to avoid the
weather effect. In case of indoor operation, please ensure that the floor is
equipped with drainage ditch or leakage-proof mechanism.
Please check the suction hose and guarantee its airtightness before start-up.
When the air foam is absorbed in the hose, the equipment is likely to be
out of order because
a leakage possibly exists .
-! DANGER !-
In order to avoid any mechanical force or tension, the suction pipeline shall
be installed. When the transmission pipeline is polluted, please apply filter to
make cleaning and protection.
-! ATTENTION !-
We advise to install one check valve to avoid the equipment shut-down
which is caused by water absence
or loss during pumping.
• All interfaces which are connected to the suction pipeline shall be
sealed by hemp and thick slurry or sealing tape. The leakage will re
-
duce the air exhaust.
• The interface of metal pipe thread shall be sealed by sealing tape.
• All components of suction pipeline shall be installed by professionals.
• The inner diameter of suction pipe shall be 25mm at least; The suction
pipe shall be kinking resistant and suitable for the vacuum environ
-
ment.
• Considering that the increasing pipe length will reduce the transmis -
sion capacity, the suction pipeline shall be as short as possible.
• The suction pipeline shall uplift the pump steadily to avoid any bubble.
• Please ensure that the suction pipeline has enough water supply; The
terminal of suction hose shall be submerged in water all the time.
• All components of pressure pipeline shall be compressive.
• All components of pressure pipeline shall be installed by professionals
Operation
The equipment can be firmly connected to the pipeline system (such as, in -
ternal water supply in families). In such case, the equipment shall apply the
highly flexible hose to connect to the pipeline system to avoid the vibration.
- ! Risk for injury ! -
When the components are unable to withstand the compression or the
installation is incorrect, the pressure pipeline is likely to burst during the
operation. Risk for liquid ejection!
-! ATTENTION !-
- The equipment is only used for industrial water supply, such as, toilet
and washing machines and shall not be used for the drinking water supply.
- Electric shock risk: Please don’t operate the equipment in humid envi -
ronment.
The equipment shall be operated only in the following conditions:
1.The equipment is only connected to the socket which has protective con -
tacts, moreover, which shall be installed, grounded and checked by profes -
sional electricians.
2. The power voltage and fuse protection shall satisfy the technical data.
3. The equipment shall be equipped with the protective device for less than
30mA residual current when the equipment is operated in the swimming
pool, garden and similar places.
4. In case of outdoor operation, the electrical connection shall be splash-
proof; The equipment shall not be operated in water.
5. Τhe extension wire shall have enough conductor cross section; The cable
drum shall be unfolded completely.
