Installation with user-supplied system separator tank
1 Pump "PU"
2 "PIS" pressure transducer
During installation, observe the following points:
• Ambient temperatures up to 35 °C
• Pipe length (see table)
• "WC" make-up connection at must be least 100 mm above the "PU" pump
intake connection.
• Minimum diameter of the intake line and the pressure line (see table).
• Adherence to EN 1717
• Recommended nominal volume of the system separator tank of ≤ 200 l
• Overflow with sufficient dimensions to match the maximum possible water
supply is installed.
• A shut-off valve is installed in the supply to the system separator tank.
Nominal diameters of the intake and pressure lines depending on the required
make-up pressure
Make-up pressure > 3.7 bar
Pressure line ≤ 10 m DN 32
Pressure line ≤ 2 m DN 32
 Note!
For installation at the same level, open the Customer menu to set the

"hst", see chapter 7.2 "Determining the P
for the controller" on page 9 .

Hydraulic connection

6.3.2.1 Connection to the facility system
 Note!
Starting up of the pump causes vibration in the device. This transfers
loud noises into the system pipes.
– Connect the pipes to the device using flexible connections.

Comply with the following requisites for the installation and connection of an
open system separator tank.
• Make-up temperatures up to 70° C
• Pipeline lengths, see chapter 6.3.1 "Floor mounting" on page 6 .
• Outlet from the system separator tank at least 100 mm above the intake
connection of the "PU" pump.
– "WC" intake line to "PU" pump with constant incline to the system
separator tank.
 Note!
At make-up temperatures > 70 °C and the use in system circuits
without system separator tanks, you must plan according to the local
conditions, see chapter 12.1 "Reflex Customer Service" on page 16 .

In system circuits with a diaphragm expansion vessel, the "PIS" pressure
transducer in the device monitors the make-up with mains water. When the
required filling pressure for water make-up drops below the minimum value, the
pressure transducer sends a signal to the device controller. The controller
activates the pump. Mains water from the system separator tank is added to the
system circuit.
Proceed as follows:
1. In the Customer menu, set the device to "Magcontrol", see chapter 9.2.1
"Customer menu" on page 13 .
2. Connect the pressure line near the connection to the diaphragm expansion
vessel.
– This ensures that the "PIS" pressure transducer detects the filling
pressure required for the make-up with mains water.
– For calculating the filling pressure, see chapter 7.2 "Determining the
P minimum operating pressure for the controller" on page 9 .
0
3. Do not use nominal diameters below the specified diameters for the
"WC"make-up lines, see chapter 6.3.1 "Floor mounting" on page 6 .
– You will avoid an undesired cycling of the make-up.
4. In solar plants, use the "BT" system separator tank to prepare the
water/glycol mixture.
– Size the system separator tank with at least 1.5 times the system
volume.
