8 Installation

The circulating pump is installed in the pipeline and as a rule, directly upstream of the service
water reservoir in such a way that the water from the last tap is pumped back to the reservoir
through the circulating pipeline. A check valve must be installed on the pump's discharge side
(primary side) to prevent pump backfl ow when the tap is opened. Assemble the pump with the
horizontally positioned pump motor when the power is shut off (the arrow on the pump housing
shows the direction of fl ow). Ensure when performing the heat insulation work that the pump
motor and the electronic housing are not insulated. The temperature sensor has to be mounted
on the return fl ow pipe ( circulation pipe ).

Install the device with the power supply disconnected and with the pump motor lying horizontal-
ly (the arrow on the pump housing shows the direction of fl ow)(Fig. 1).
When performing insulation work, ensure that the pump motor and the electronics housing are
not covered in insulation.
Observe the permissible mounting positions:
