T.I.P. Maxima 300 IX Mode D'emploi page 14

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 authorized
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.
MALFUNCTION
1. The pump is not discharging
any liquid, the motor is not
running.
2. The motor is running, but the
pump is not discharging any
liquid.
3. The pump stops after a short
time of operation because the
thermal motor protection
feature has triggered.
4. Intermittent or irregular
operation.
12
POSSIBLE CAUSE
1. No current.
2. Thermal motor protection feature has
triggered.
3. The capacitor is defective.
4. The pump wheel is blocked.
5. The floating switch is defective.
1. The intake openings are clogged.
2. The pressure line is clogged.
3. Air penetrates into the pump body.
4. The min. suction level was fallen short of;
possibly incorrect setting of the floating
switch, motion of floating switch restricted,
floating switch defective.
5. Check valve (non-return valve), if present,
is blocked or defective.
1. The electrical supply does not correspond
to the information given on the type plate.
2. Pump or intake openings are blocked by
solids.
3. Liquid is too viscous.
4. Temperature of the liquid is too high.
5. Pump is running dry.
1. Pump wheel obstructed by solid matters.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Mains voltage out of tolerance.
5. Motor or pump wheel defective.

ELIMINATION
1. 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.
1. Please use a device complying with GS
(German technical supervisory authority)
to check the voltage of the lines of the
connection cord (safety information to be
observed!).
2. Remove possible congestion.
3. Pump may not be suitable for this liquid. If
feasible, the liquid should be thinned.
4. Make sure that the temperature of the
liquid being pumped does not exceed the
max. admissible value.
5. Eliminate causes of dry-running.
1. Remove solids.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Make sure that mains voltage matches that
indicated on the type plate.
5. Please contact the customer service
department.
