Design
The LK Minishunt M60 is intended for use in
smaller under floor heating areas (up to 60 m² de-
pending on heating requirements/laying proce-
dures etc.) and is connected to an existing heating
system. The shunt unit consists of an automatic
speed-controlled circulation pump for the under
floor heating circuit, a maximum limit function
for the feed temperature, a return valve for the
under floor heating circuit, a fill/discharge and
air bleed valve plus a thermostatic valve unit, fit-
ted with a thermostat and a sensor, connected to
a capillary tube.
Connectors for a under floor heating circuit and
mini manifolds for 2, 3 or 4 under floor heating
circuits are provided as accessories. Possible pipe
connections for floor heating are dim. 8, 12, 16
and 20 mm. The installation can be concealed in
built-in or wall-mounted cabinets, see heading
Installation cabinets
.
1. Thermostat valve.
2. Switching between single or twin pipe
radiator systems and shutting-off against
the return connection of the primary side.
When delivered, the minishunt is set for a
twin pipe radiator system with the outer
hex-screw spindle (dim. 10 mm hex.) scre-
wed in and the inner hex-screw spindle
(dim. 4 mm hex.) screwed out. For single
pipe systems the outer hex-screw spindle is
gradually screwed out until correct
