Maintenance And Storage; Troubleshooting - Ribimex Ribiland PRJET61 Bedienungs- Und Wartungsanleitung

- The pump starts and stops automatically when the pressure in the vessel is approximately 3 bar.
- Slowly open the discharge valve. The pump begins to discharge, without its engine running, through the
water supply in the tank.
- When the pressure in the tank drops below about 1.5 bar, the pump starts and remains on until the pressure
of the tank reach about 3 bar.
- To stop the pump cycles, slowly close the discharge valve.
- Always follow these instructions to avoid creating excess pressure in the system and avoid "water hammer"
effect.
5.3- Advise for users
IMPORTANT!
- Do not operate the pump without water in the pump body: extended operation of the pump when the
discharge valve is closed, can seriously damage the pump.
- In case of power failure, switch off the power or unplug from the power outlet.
- In case of prolonged non-use, ensure to switch off the power.

6.3- Troubleshooting

Trouble
Difficult start
Less water outlet
Sudden stop
Main reasons
1. Power voltage too low;
2. Impeller clogged
3. Big loss of cable voltage
1. Head to 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
1. Switch disconnected, or fuse
burnt
2. Impeller clogged
Solution
1. Adjust voltage to 0.9 to 1.1 times the
rated range.
2. Adjust clogged part.
3. Select the proper cable
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.
