normal, the motor restarts.
Never place hands anywhere near the turbine during this phase. If remedial action is necessary,
always unplug the pump from the power supply first.
3. The pump is also fitted with an automatic bleed device to evacuate any air that might have got into
the suction circuit.
When the water level drops below the vent located in the middle of the pump body, water is
evacuated by this hole so as to automatically bleed the circuit: this is not a fault, but corresponds to a
normal function of the pump.
4. After having pumped dirty water, water containing sand or other abrasive material, the pump
should be rinsed with clear water.
VI. MAINTENANCE AND STORAGE
Before any intervention on product, ensure that product is disconnected from its power source.
6.1- Maintenance
- In winter the pump must be thoroughly drained or kept in "frost free" conditions.
- Regularly rinse out the pump with clean water, including the suction circuit.
- Avoid pumping liquid containing abrasive materials such as sand.
- Before each re-use, ensure that all parts of the pump are in good working order.
- Clean plastic parts with a soft clean cloth.
- Do not use aggressive cleansers (solvents or abrasive cleansers), or an abrasive sponge.
6.2- Breakdown
Never attempt to dismantle the pump.
If necessary, have it checked and repaired by an authorized centre (consult your dealer).
6.3- Trouble shooting
Trouble Main reasons
Difficult start 1. Power voltage too low;
2. Impeller clogged
3. Big loss of cable voltage
4. Stator winding burnt
Less water outlet 1. Head too high
2. Strainer and inlet hole clogged
3 Impeller worn badly
4. Submersion too shallow and air sucked
in.
5. Discharge hose disconnected, leaking or
worn out
Sudden stop 1. Switch disconnected or fuse burnt
2. Impeller clogged
3. Stator winding burnt
Stator winding 1- Run too long
burnt 2. Winding turn-to-turn short circuit or
short circuit between phases due to
mechanical seal leakage
3. Impeller clogged
4. Pump started too frequently
5. Pump overloaded
Solution
1. Adjust voltage to 0.9 to 1.1 times the
rated range.
2. Adjust clogged part.
3. Select the proper cable
4. Rewind and overhaul
1. Use within the rated head range
2. Remove water weed or foreign matter
3. Replace impeller
4. Adjust the submersion depth to no less
than 0.5m
5. Check hose connection, fix it or replace if
required.
1. Check whether the head in use or power
voltage are in compliance with requirements
and adjust accordingly.
2. Remove foreign matter
3. Rewind and overhaul
