T.I.P. Maxima 400 SX Mode D'emploi page 14

The electrical pumps of the T.I.P. MAXIMA series are equipped with an integrated thermal motor
protection feature. In the case of overload, the motor will switch off independently and on again after
cooling down. For possible causes and their elimination, please refer to the "Maintenance and
troubleshooting" section.
8. Maintenance and troubleshooting
Prior to carrying out any maintenance work, the pump must be separated from the
electrical mains. If you fail to separate the unit from mains, there is a risk of an
inadvertent start of the pump.
We decline any liability for damage caused by inappropriate repair attempts. Any
damage caused by inappropriate repair attempts will avoid all warranty claims.
Observing the conditions of use and the ranges of application of the present device will reduce the risk
of possible operational malfunction and contribute to extend the lifetime of your unit. Sand and other
abrasive matters contained in the liquid discharged will speed up the process of wearing and tearing
and accelerate the drop in performance.
If the unit is operated properly, it will not require any maintenance. Where applicable, you may clean
the hydraulic part from sediments and dirt. This can be done by counter-flushing the unit with clear
water using a hose to be connected through the pressure port of the pump. To remove tenacious dirt,
the foot of the pump (8) can be removed by loosening the screws located at the bottom of the pump.
To avoid any hazard, any further disassembly as well as the replacement of parts must only be done
by the manufacturer or a by an authorised service provider.
Water left in the pump may freeze in case of frost and thus cause considerable damage. Therefore,
the pump must be removed from the liquid being discharged and fully drained when temperatures are
below the freezing point of the liquid. Please store the pump in a dry, frost-protected place.
In the case of malfunction, you should first of all check whether it was caused by an operating error or
some other reason which cannot be attributed to a defect of the device - for instance a power failure.
The list below shows some possible malfunctions of the device, possible causes and tips on their
elimination. All the measures referred to may only be carried out with the pump being separated from
the electrical mains. If you yourself feel unable to eliminate any of these malfunctions, please contact
the customer service department or your point of sales. Any repair beyond the scope specified below
must only be performed by qualified staff. Please bear in mind that all warranty claims will become
void in the case of damage caused by inappropriate repair attempts, and that we decline any liability
for any ensuing damage.

ELIMINATION
Please use a device complying with GS
(German technical supervisory authority) to
check for the presence of voltage (safety
information to be observed!). Please verify
the correct position of the plug.
2. Separate the pump from the electrical
mains, allow the system to cool down,
eliminate cause.
3. Please contact the customer service
department.
4. Eliminate blocking of pump wheel.
5. Please contact the customer service
department.
1. Remove possible congestion.
2. Remove possible congestion.
3. Start pump several times so that the entire
air will be driven out.
4. Make sure that the minimum suction level
is not fallen short of; if necessary, adjust
floating switch properly or make sure that it
can move freely; in the case of a defective
floating switch, please contact customer
service.
5. Eliminate blocking of the check valve (non-
return valve) or replace, if damaged.
