2. Installation and operation

2.1.5 Installing a heat flow meter (UK-Z and MK-Z only)

Delivery includes a 1" x 130 mm pipe nipple in the return line of the UK-Z or MK-Z
to install a meter. Attention: A meter should only be installed once the system has been flushed through.
A 1" meter with an installation length of 130 mm is installed in place of the pipe nipple. For a 3/4" meter
with an installation length of 110 mm, two flat sealing reductions (1" male thread × 3/4" female thread)
are included. These are installed on the meter. With the reductions and the ¾" seals, the meter has an
installed length of 90 + 2*9 = 108 mm. By pulling out the telescopic piece
between the 1" union nuts. A T-piece (1" male thread x ½" female thread x 1" female thread) incl. extension

piece is included for a directly immersed supply sensor. Cut holes in the insulation shells as required
(e.g. in the case of a heat flow meter or removable control unit).

2.2 Hydraulic connection

Connect the supply and return lines according to the following illustrations or application examples. The side with the 1 ½" male thread is
prepared for direct installation on manifolds. Without a manifold, use the union fittings for connecting to the heat generator. The heating
circuit is connected to the side with the female thread.
UK, UK-Z
Note
UK, UK-Z: Supply line and return line are interchangeable
MK: Also available as a variant with the supply line on the left
MK-Z: Supply line and return line are interchangeable (by swapping the mixing fitting from the right to the left)
Constant heat
regulation set: The pipe between the ball valves in not a hydraulic connection; it is used as a sensor mounting.
Separation system: At bottom with screw fitting and double nipple for direct connection to another pump group with 1" female thread
and 125 mm distance. Install the MAG connector set (included in the pump group scope of supply) and vent line of
the safety valve on the safety group.
