garden pump TGP 1025 E
Insufficient or decreasing conveying capacity:
•
Check whether the suction height or pump height exceeds
the max. specifications indicated in the technical data, and
reduce it if necessary.
•
Check whether the hose line is kinked or blocked. Remove
kinks and / or blockages.
•
Check whether the suction line is clogged at the intake
opening. Remove any dirt.
•
Inspect both the pressure and suction line for leaks, and
replace them if necessary.
The pump switches on and off too often:
•
Check whether the precharge pressure in the pressure
tank is set correctly; it should be 1.5 to 1.8 bar. Please
refer to the chapter Checking the precharge pressure in
the pressure tank.
If the pressure tank cannot maintain the set precharge
pressure, the membrane inside the pressure tank is
damaged and must be replaced. If so, contact a specialist
company or Trotec.
•
Check whether the check valve at the suction line is
blocked or damaged. Remove the obstruction or replace
the check valve.
Note
Wait for at least 3 minutes after maintenance and
repair work. Only then switch the device back on.
Your device still does not operate correctly after these

Please contact the customer service. If necessary, bring the
device to an authorized specialist electrical company or to
