When installing the unit, please make sure that the connection cable is not subjected to
excessive pulling strain since this may cause damage to the electrical line and the electrical
connector.
All connection lines have to be perfectly tight since leaking lines may affect the performance of the pump and
cause considerable damage. Therefore, please use Teflon tape to seal the contact surfaces between the
threaded sections of the lines and the connection with the pump. This use of sealing material such as Teflon tape
is the only way to ensure an airtight assembly.
When tightening threaded connections, please do not apply excessive force which may cause damage.
5.1. Installation
The TLS 100 E anti-dry-running feature is to be installed directly and in a vertical position between the pump
outlet and the pressure line. Please observe the correct seating of the gasket in the rotating union nut of the
pressure line
Schematic Installation
Once the anti-dry-running feature properly installed, it can be connected to the current mains through a grounded
(earthed) mains socket. The mains plug of the TLS 100 E connects directly to mains. The green indicator lamp
will show whether voltage is present in the system. Subsequently, the mains plugs of the pump is to be connected
directly to the socket of the TLS 100 E.
The ex-factory setting causing the pump to cut out in the case of malfunction is 180 seconds. This setting is in
particular recommended for the operation with the pump with a connected pressure smoothing system - for
instance, a domestic booster set -, in order to allow for the pump sufficient time to fill the pressure smoothing tank
without causing the anti-dry-running feature to switch to the “error” condition.
5.2. Functional parts and wiring
1. Reset key:
Used to reset the unit following a stop caused by the
absence of water .
2. “Error“/Dry-running“ indicator lamp (red):
Flashing of the lamp at short intervals indicates a disruption
of the water flow. Uninterrupted lighting of the indicator
signals a stop caused by the absence of water.
3. Mains voltage indicator lamp (green)
4. Grounded (earthed) socket for the mains plug of the pump
5. Threaded cable connector for the mains voltage conduit
6. Water inlet connector
7. Water outlet connector
8. Rotary setting button for the cut-out delay:
Min. 10 seconds, max. 180 seconds.
