Electrical Connections
The electrical connections should be made as in-
dicated in the Diagram which can also be found
on the inside of the circuit Cover.
The cable bushings and circuit board cover must
be properly assembled and secured in order to
gauarantee IP65 grade protection of the elec-
trical components. External enabling inlet (e.g.,
level sensor): this is an optional function, with
NO logic, for connecting a clean contact which
disables the system if the terminals are not short-
circuited (e.g., open level signal). The connected
contact must have 1 A minimum capacity.
To connect the cable to the terminals, drill the co-
ver in the dedicated area, with diameter suitable
for fitting the feedthrough provided.
Dry running
There is no flow and the pressure is lower than
that of the pump start-up pressure (Pm). It oc-
curs when there is no water. After 15 seconds
TEEPRES stops the pump and indicates an ER-
®
ROR message. TEEPRES
tries to resume NORMAL SERVICE at intervals
of increasing time (15, 30, 60 minutes and suc-
cessively once every hour). If TEEPRES
any pressure and/or flow, NORMAL SERVICE is
resumed, otherwise, the pump is stopped again
until the next attempt is made.
A MANUAL attempt to resume NORMAL SER-
VICE can be made at any time.
Frequent start-up
The repeated stopping and starting of the pump at intervals of less than 2 minutes from each
other. This occurs when the flow rate is less than 2 litres/min (0,5 gpm). This may cause dama-
ge to the pump. In the event of leaks or extended use at excessively low flow rates (less than
2 litres/min (0,5 gpm)), the pump may be started/stopped as often as once every few seconds,
putting the pump at risk of damage. In this case, after about 30 minutes, TEEPRES
pump for the following 30 minutes (in order to let it cool down) and indicates an ERROR mes-
sage. If the time interval between the starts-stops is more than 10 seconds (and therefore poses
less of a risk to the pump), TEEPRES
Once that enough time has passed to allow the pump to cool down it is restarted AUTOMATI-
CALLY. The pump may be restarted MANUALLY any time.

Priming the pump
For instructions on how to prime (fill) the pumpe, see the pump manual.
TEEPRES is fitted with a check valve: do not use the TEEPRES
