Function & requirements
In order for the correct operation of the LK Mi-
nishunt M60/under floor heating system, the
existing heating system must be fitted with a
circulation pump and preferably with a weather
dependent flow temperature control. With the LK
Minishunt M60 the temperature of the heating
system is adapted to the lower temperature that
is required by the under floor heating circuit. Pri-
or to assembly, the heating system must be flus-
hed through and must not contain any impurities
or additives, which can damage the shunt.
Assembly
The LK Minishunt M60 must be mounted at a hig-
her level than the under floor heating installation
in order to assist air bleeding. Pay attention to any
structure-borne noise from the minishunt when
placing it. The shunt should preferably be place
in specially designed cabinet to fulfil Sweden’s
plumbing safety regulations, see heading
Instal-
lation cabinets
.
Pipe connection
The minishunt´s primary connection is provided
with a ¾” EuroCone thread. Pipe connection to
the primary side is made using the enclosed fit-
tings for 15 mm Cu Connectors for Cu 12 mm
and to PEX-/PAL pipes dimension 16x2, 20x2
and 20x2, 8 mm are available as accessories. The
secondary connections of the minishunt have ½”
female thread. The under floor heating pipes are
connected for a floor heating circuit using LK
Connection Coupling ½” male thread for pipe
dim. 8,12,16 or 20 mm. For more circuits, LK Mini
Manifold 2, 3 or 4 circuits for pipe dim. 8, 12, 16
or 20 mm, are available.
Electrical connection of circulation pump
Electrical connection of the pump must be carried
out by a qualified electrician in accordance with
applicable regulations. The pump is equipped
with a fixed 3-core cable and Wilo-connector with
integrated strain relief. The Wilo-connector repla-
ces the requirements for 2-pole circuit breaker.
Connect the supply cable L, N, PE to the Wilo-
connector according to the following sequence.
The electrical connection must be fused with Max
10 A slow blow fuse. Note that at any maintenan-
ce/repair work the pump power supply must be
disconnected. Motor protection for the circula-
tion pump is not required.
