LK Minishunt M60n circulation pump
Wilo Para RSB 15/6 SC
Design
LK Minishunt M60n is a shunt group intended for use
when smaller underfloor heating areas are to be con-
nected to an existing heating system. LK Minishunt
M60n adapts the heating system temperature to the
lower temperature necessary for the underfloor heat-
ing system. Its capacity can normally be set at a heat-
ing need of 50 W/m² to a maximum 60 m² underfloor
heating area. Capacity is however dependent on pri-
mary temperature, pressure, laying method etc.
• For underfloor heating areas up to 60 m
• Compact design.
• Energy efficient circulation pump.
• Thermostat-controlled maximum limit of supply
temperature.
• Switchable between single or twin pipe systems.
• VF valve.
• Easy filling & air bleeding.
• Expandable to 2, 3 or 4 underfloor heating cir-
cuits.
Supplied with product
• Circulation pump Wilo Para RSB 15/6 SC, with
automatic speed control.
• T
hermostat with capillary tube sensor, length 2 m.
• Thermometer to place in one of the shunt group's
thermometer pockets.
• Hose 0.5 m for air bleeding.
• Primary connector ¾" EuroCone and 2 connectors
for CU15.
• Bracket.
Accessories
• Accessories for the primary connector include
connectors for CU12 mm and PEX-/PAL pipes
dim. 16x2, 20x2 and 20x2.8.
• The LK Elbow Pipes M60n for connecting the
primary connector when the feed pipe is from
below or above. The elbow pipes enables compact
assembly.
• Connection couplings for underfloor heating
pipes dim. 8, 12, 16 and 20 mm.
• The LK Mini Manifold for 2, 3 or 4 underfloor
heating circuits.
• Installation cabinets for built-in or wall mounting,
see heading Installation cabinets.
• The LK Heater 350 is an electric comfort heater
for underfloor heating installations using the
LK Minishunt M60n. The electric heating car-
