2.2 Good pump
installation practice
The 120 pump must be mounted in the upright posi-
tion and not inverted or placed on its rear face.
Two models are available, fitted with either a 114DV
pumphead or a 102R pumphead, in either case
pumping with Pumpsil silicone tubing only. The
120F is designed for fluid transfer only. It cannot be
run at pressure.
2.3 Switching the
pump on
The pump is powered by a dedicated 24V external
DC power supply unit which is supplied with the
pump.
Plug the power supply’s output connector into
the power socket on the rear of the pump.
Plug the power supply unit into a mains power
outlet and switch on.
Load the pumphead with tube: see Section 3 of
these instructions.
The pump is now ready to operate according
to the default settings.
* If the pump is isolated from mains power while it
is running, it will start when power is re-connected:
it is not necessary to press START.
