damaged pump must not be used. In any case of damage, the pump has to be inspected by qualified service
staff.
If present, open a shut-off device within the pressure line, for instance a water tap. Insert the mains plug into a
230V AC socket. The pump will start to run immediately. For the first operation: The anti dry running protection
will delay the start by approximately 10 seconds. Shortly, the pump will start to discharge water.
For stopping the operation close the end device (e.g. the water tap). The pump will stop operation as soon as the
maximum pressure is reached. If the end device is opened and the pressure inside the system falls under 1.6 bar,
the pump starts operation again.
To stop the operation of the pump, please pull the mains plug off the socket.
Dry-running - i.e. the operation of the pump without discharging water - has to be avoided in any case since the
absence of water will make the pump run hot. This will cause considerable damage to the unit. The most common
causes of dry running include blocked suction openings and lack of pumped liquid in the pump housing
(especially in surface operation). In this context, please note that the water level may vary as a result of the
withdrawal of water, weathering influences, seasonal changes or other reasons. For this reason it is
recommended to install an automatic water level indicator.
The electrical pumps of the T.I.P. SubGarden 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. Automatic operation / anti dry running protection
The integrated electronic system enables an automatic operation of the pump in order to use the pumped water
as if it would come out of tap water system. The pump can be switch on or off by closing the water tap or other
end devices.
As soon as the power cord plug is connected, the pump starts with a delay of 10 seconds and discharges water.
After closing the end devices and building up the maximum pressure in the system, the pump stops operation.
The pump will automatically be switched on, if the end devices are opened and pressure in the system falls below
1.6 bar.
In contrast to pumps that are equipped with pressure vessels such as, for instance, domestic booster systems,
the automatic cut-out of the pump will not occur upon the reaching of a specific cut-out pressure, but rather by the
reduction of the flow rate down to minimum value as a result of the closing of consumers. Inside the water system
will be the maximum pressure the pump can build up (approx. 4.3 bar). In this process, the electronic pump
control will delay cutting-out by 30 seconds. This method will decrease the cut-in/cut-out frequency of the pump at
low flow rates and thus contribute to a sparing operation of the unit. This feature is also activated in the case of
the pumps dry-running and thus protects the device efficiently from damage which may be caused by operation in
the absence of water.
In case of water shortage the pump tries to discharge water for approximately 30 seconds and then stops for 10
seconds. Then the pump tries to start again and will repeat this start cycle in total 3 times. After a break of 30
minutes, the pump will try again 4 start cycles. If it is still not possible by that time to discharge water, because
e.g. the intake openings is clogged or the water level is too low, the pump will indicate an error (error modus) and
cannot be started without help from the user. Make sure you remove the reason for dry running and the water
level is sufficient for operating the pump. In order to restart the pump, you must rest the pump by unplugging the
power cord for approximately 10 seconds. The pump will start operation by connecting the power cord again to
the electric power supply.
9. 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.
If the water pumped is not sufficiently clean, it may be necessary to clean the intake filter (5) with a steel brush in
order to remove the dirt that has accumulated on the outer surface. To do this the pump must be disconnected
from the electrical power supply and taken out of the water.
