FOREWORD
LK 212 SolarStation is a compact dual-pipe solar pump unit with
or without an inbuilt solar heating controller, which transfers heat
from the solar collector to the accumulator tank. The pump unit
contains all the necessary components for safe operation and
control of the solar heating system.
SCOPE OF DELIVERY
• Valve combination for filling and draining with 2 - 12 l/min
flowmeter and built-in controlling/shutoff valve. Connections:
1" male thread and ¾" female thread. Pipe connections: ¾"
male thread.
• Safety valve 6 bar with manometer 0 - 10 bar,
G ¾" male thread for expansion tank, ¾" female thread for
drain connection.
• Ball valves with 1" male thread and ¾" female thread with
built-in thermometer (0-120°C) and non-return valve. Red
knob for supply and blue knob for return. Inbuilt solar heating
controller, applies to the versions where this is included.

INSTALLATION
Select an appropriate location in the boiler room for the pump unit
and expansion tank. Remove the front.
Note! National rules and safety regulations must be complied
when installing the product.
The pump unit is mounted at a child-safe height so that the solar
heating controller's digital display can be easily used and read.
Ensure that there is room for the expansion tank.
Connect the safety group (6). The expansion tank is connected to
¾" male thread on the safety group (under manometer). Steam
can escape from the safety valve so a heat-resistant overflow pipe
must be connected to the safety valve (7) and guided to a heat-
resistant vessel.
As standard, the solar heating controller has 3 or 4 sensors,
depending on which type of control is used (collector sensor, tank
sensor and additional sensor).
The sensors are mounted according to the installation and
operating instructions for the solar heating controller.
If the sensor cables have to be extended, the cable diameter must
be at least 5 mm.
Note! The sensor cables must not come into direct contact with
pipes, valves or high voltage cables. Use cable ties for instance to
keep them apart.
All pipes connected to the pump unit must be insulated.
Monopropylene glycol is recommended as a heat transfer fluid to
minimise the risk of corrosion to components and thread seals.
