Maintenance; Preservation - Kripsol KNG Manuel D'instructions

●
Ensure that the motor turns freely. Never start the pump if the motor is blocked. The motors
have a ridge at the end of the shaft in the fan area that allows users to manually check the motor
rotation using a screwdriver.
●
Start the motor for a few seconds, no more than 3, and check that the rotation direction
matches the direction of the arrow shown on the fan cover. If this is not the case, advise an
authorised service technician. To change the rotation direction on three-phase motors, swap
the position of two of the motor's power supply cables.
●
Check that the motor does not exceed the consumption level indicated on the motor rating
plate. If it does, adjust using the valve located on the pump discharge.

7.2 MAINTENANCE

Disconnect the power before performing any maintenance task
on the pump.
DIN Standard
4844-W8
●
Remember, all changes to the position of the selector valve or the valve manifold of the
filter must be made when the pump is stopped.
●
Remember to open the intake and discharge valves again before re-starting the pump.
●
The motor bearings are self-lubricating and therefore do not require lubrication.
●
The pump's mechanical seal is lubricated with water from the pump itself. It does not require
lubrication. The mechanical seal will need to be replaced occasionally due to wear or
damage. Replace with KRIPSOL original spareparts.

7.3 PRESERVATION

Disconnect the power before performing any maintenance task

●
If the pump is not used for a long period of time, or there is a danger of freezing, empty
the body of the pump by releasing the drain plugs equipped with O-rings. First check that the
installation, pump, filter and pipes are not pressurised.
Before re-starting the pump, replace the drain plugs and their respective O-rings and prime the
pump as described in point 7.1 of this manual. Keep the motor covered and dry while in storage.
●
To prevent issues of condensation or corrosion, do not cover or wrap the pump with plastic film
or bags. Keep the pump in a dry place.
●
Do not start the motor if it has been affected by flood water. Notify a qualified technician to
disassemble the motor and dry it out if possible.
●
Preservation of outdoor installations:
1. Empty the installation
2. Dry as much as possible.
3. Lubricate seals with neutral Vaseline.
4. Re-assemble.
5. Leave drainage covers removed while the pump is not in use.
