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 backflow when the tap is opened.
In the lower part oft he UPH 20-KS,
a non-return valve and a ball valve is
already integrated.
A shutoff valve is installed on the pump's
inlet side (secondary side) to make servicing easier. 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 flow). Ensure when performing the heat insulation work that the pump motor and
the electronic housing are not insulated.

Install the device with the power supply disconnected and with the pump motor lying horizon-
tally (the arrow on the pump housing shows the direction of flow)(Fig. 1).
When performing insulation work, ensure that the pump motor and the electronics housing are
not covered in insulation.
