1. INTRODUCTION
CSE2 MIX F G60 1F twin-line pump station is designed for mixed heating circuits. It provides
flow through the heating system, mixes to the outlet temperature using a motorized mixing
valve (controlled by an external controller). The pump station includes a filter with magnet,
so it is also suitable for older steel pipe systems. It can be easily mounted on a wall or on

Description of Pump Frofiles
a) Proportional pressure
• This mode is suitable for heating systems with radiators, to reduce noise caused by
heating fluid flowing through thermostatic valves.
• Head (pressure) decreases with decreasing flow rate (increasing system pressure
drop).
• Pump operating point: lies on the selected proportional pressure curve depending on
the current system pressure drop.
CONTROL MODE DESCRIPTION
Proportional
pressure
I The lowest curve of proportional pressure
II The middle curve of proportional pressure
III The highest curve of proportional pressure
AUTOADAPT
Automatically controls performance in the range from
the highest to the lowest proportional pressure curve
b) Constant pressure
• This mode is suitable for underoor heating or for piping of a bigger size. It is also
suitable for all applications without variable characteristics (e.g. pumps for heating up
a HW storage tank) or for a circuit with a heat exchanger.
• Head (pressure) remains the same in the whole range of ow rates (does not change
with the system pressure drop).
• Pump operating point: moves on the selected constant pressure curve depending on
the current system pressure drop.
CONTROL MODE DESCRIPTION
Constant
pressure
I The lowest curve of constant pressure
II The middle curve of constant pressure
III The highest curve of constant pressure
AUTOADAPT
Automatically controls performance in the range from
the highest to the lowest constant pressure curve
c) Constant speed
• This mode is suitable for the maximum utilization of the pump performance or for use
in systems with constant resistance which require a constant pumping performance.
• Head (pressure) increases with decreasing ow rate (increasing system pressure
drop).
• Pump operating point: moves up or down on the selected curve depending on the
current system pressure drop.

ACTUATOR ELECTRICAL WIRING

2 – (black)
3– (brown)
The actuator is factory set to motorized control and ready for operation.
Should it be inevitable to remove it or replace, please follow the instructions
in the appendix.
230 V, 50 Hz
3.2. MIXING VALVE WITH ACTUATOR
The LK 840 mixing valve is equipped with a 3-point control actuator. The current valve member
position is obvious from the position of the line in the sightglass of the control knob. The slide
switch on the actuator housing can be used to switch between motorized and manual control.
When the manual control is set, the actuator is controlled by turning the knob.
3.3. CHECK VALVE
A check valve located downstream of the filter prevents natural circulation in the heating
circuit.
3.4. FILTER WITH MAGNET
The filter located in the return line of the pump station is designed to collect particles from
heating water. It consists of a brass housing, removable stainless-steel strainer collecting
coarse dirt, and a brass lid with a magnet that attracts magnetic particles.
The filter needs to be checked regularly, and cleaned when needed. Turn off the circulation
pump, close the ball valve upstream of the filter. Water inlet downstream of the magnet is
closed by the check valve. Unscrew the filter lid, remove the stainless steel strainer and flush
thoroughly. Wipe the impurities on the magnet and re-assemble the filter by inserting the
strainer, screwing in and tightening the lid.
3.5. BALL VALVES
Ball valves are intended to isolate the pump station from the heating circuit. Then it is not
necessary to drain the heating circuit for servicing (incl. cleaning the filter). In order to have
a more solid hydraulic section of the pump station, they are fixed to the rear mounting plate.
The ball valves are controlled by a lever that is placed inside the pump station insulation. The
valve is closed or opened by turning the lever by 90°. The state of the valve is indicated by
the groove on the control hexagon of the valve. The ball valve can be accesses only after the
front section of the insulation is removed. As a result, unintentional closure of the system by
an unauthorized person is not possible.

5. PUMP STATION INSTALLATION
The pump station is designed to be mounted on a wall or a manifold with 125 mm connection
pitch. In the rear section of the insulation there are two mounting holes for fixing the metal
plate to the wall. Mounting holes pitch is 80 mm.
The package includes a mounting kit that is used to fix the pump station to the
intended place. The mounting kit includes:
Screw 5x50, round head 2 pcs
6.4 stainless steel washer, DIN 9021/A2 2 pcs
Wall plug 8mm TX 2 pcs

6. TEMPERATURE SENSOR INSTALLATION
The ball valve housings are equipped with a sheath for the temperature sensor, where the
sensor can be inserted and secured by a fixing screw against being pulled out. In the top
and bottom section of the insulation there are passages to run the cables through, then it is
necessary to cut the appropriate part of the passage lock from the front part of the insulation
with a knife, so that the exiting cables are firmly wrapped around by the lock.
