Introduction
The V-submersible-pump for consist of a motor and a pump. Depending on the water level the float
switch can turn the pump on and off automatically. The thermal protection of the motor can
automatically turn the engine off if it is running too hot or overburdens itself, therefore security
measures are kept in force even in roughest conditions. The pump needs to be submerged entirely.
Operating Conditions
1. The maximum depth to submerge the pump is five metres seen from the middle of the rotor.
2. The temperature of the liquids being pumped through may not be above 40 degrees Celsius.
3. The pH level of the liquids being pumped may be between 4 and 10.
4. The kinematic viscosity of the liquids being pumped should be between 7x 10-7 and 23x10-6 m2/s.
5. The maximum density of the liquids being pumped through is 1,2 x 1000 kg/m3 .
Safety Instructions
CAUTION:
The use of this device is allowed on standing bodies of water, garden ponds or swimming ponds and
their surrounding areas only with fault current protection-switch with a triggering nominal current up to
30mA (according to VDE 0100 Article 702 and 738). The device is not suitable for use in swimming
pools, paddling pools and other bodies of water in which during operation people or animals linger.
The operation of the device during the stay of people and animals in the danger zone is not allowed.
Ask your electrician. The device is not intended for use by persons (including children) with impaired
or limited physical, sensory and mental abilities or lack of experience and/or real knowledge, unless
they are supervised by a person responsible for their safety or you follow the instructions made by this
person how to use the device correctly. Children should be supervised to make sure that they do not
play with the device.
ATTENTION:
Run a visual inspection of the device before every use. Do not use the device if the safety
appliances are damaged or worn out. ever override safety regulations.
Use the device exclusively according to the intended purpose stated in the instructions for
use.
You are responsible for the safety of the working environment.
If the cable or the plug is damaged because of external influences, the cable must not be re-
paired! It has to be replaced with a new one. This work can be carried out only by an
electrician.
The voltage indicated on the type plate of the device of 230 Volt alternating voltage has to cor-
respond to the existent mains voltage.
ever lift, carry or fixate the device by using the power cable.
Make sure that the electrical plug connection is placed in a flood-proof area and is protected
from moisture.
Before working on the garden pump disconnect the appliance by taking the plug out of the
socket.
Avoid exposing the pump to a direct water jet.
The user is responsible for the compliance with location specific safety and installing
regulations. (Ask an electrician).
Consequential damage arising from flooded rooms caused by dysfunctions of the appliance
must be avoided by means of the appropriate measures. (Installing an alarm system, reserve
pump).
In case of malfunction the repair work can be carried out only by a qualified electrician or
specialist.

The pump must not run dry or having a completely closed intake port. The manufacturer’s
guarantee is no longer valid if the damage is caused by dry running.
The submersible pump must not be used for swimming pools.
The pump cannot be employed for potable water circuits.
WARNING:
Read all safety guidelines and instructions carefully. on-compliance with the safety rules and
regulations can lead to an electric shock, fire and/ or serious injury. Keep the instructions and the
safety guidelines in a safe place in case you need them in the future.
Resistance
The maximum temperature of the pumped liquids should not exceed +40°C during continuous
operation.
This pump is not allowed to be used for burnable and explosive liquids, as well as gas. Also the use of
other liquids, especially engine fuels, cleaning detergents and other chemical products is prohibited!
Installation
Installing the pump can be done the following way: either in a fixed position with fixed piping or in a
fixed position with flexible piping.
ATTENTION:
Please note that the pump may not be installed hanging of its pressure pipe or of its electricity cable.
The submersible pump engine must be hung up via its handle/ stand on its shaft floor. If the water
level is too low, the mud in the shaft can easily dry up and hinder the water flow. Therefore it is
required to check the submersible pump engine frequently (by doing a start-up test).
The float switch has been adjusted for immediate use.
Maintenance
1. Check the supply cable frequently. Change them if necessary.
2. After 2000 hours of operating time the pump should be maintained the following way:
Demounting of the pump: Check the easily worn parts, e.g. bearings, mechanical parts and oil seals,
o-rings. Exchange the warn parts.
Oil change: open the oil exchange cap and pour peanut oil up to a height of 80 % of the shaft volume.
Leak test: After the maintenance work the leak tightness needs to be checked up on with air pressure:
Fill the pump with 2 bar and watch the pressure gauge. If the air pressure does not drop within three
minutes, the pump is leak proof.
