Installation
 Note!
Use a pressure reducer in the "WC" make-up line if the idle pressure
exceeds 6 bar.

Note!
If you use make-up water from the potable water system, you may need
the Reflex Fillset for the "WC" make-up line,  4.6 "Optional equipment
and accessories",  29.
• Reflex make-up systems such as Reflex Fillset are designed for
make-up lines with a flow rate < 1 m³/h.
7.3.5 Fitting the thermal insulation
Install the optional thermal insulation (2) around the primary tank (1) and close
the insulation with the zip fastener.
 Note!
For heating systems, insulate the primary tank and the "EC" expansion
lines against heat loss.
– Thermal insulation is not required for either the primary tank top
or the secondary tank.
 Note!
On-site, install thermal insulation when condensate forms.
7.3.6 Installation of the weight measuring cell
ATTENTION
Damage to the pressure load cell due to unprofessional installation
Incorrect installation may result in damage to the "LIS" level sensor,
malfunctioning and incorrect measurements from the pressure load cell.
• Comply with the instructions regarding the installation of the pressure
load cell.
The "LIS" level measurement uses a pressure load cell. This pressure load cell is to
be installed after the primary vessel has been placed at its final position,  7.3.3
"Tank installation",  34. Comply with the following instructions:
• Remove the transport safety device (squared timber) at the mounting foot
of the primary vessel.
• Replace this transport safety device with the pressure load cell.
– The pressure load cell can optionally be fastened to the mounting
foot of the primary vessel using the supplied screws. However,
fastening is not necessary.
• Avoid shock-type loading of the pressure load cell by, for example,
subsequent alignment of the vessel.
• Use flexible hoses to connect the primary vessel and the first secondary
vessel.
Use only the supplied connection sets,  7.3.3 "Tank installation",
–
 34.
• Perform a calibration of the filling level when the primary vessel is aligned
and fully emptied,  8.6 "Parametrising the controller in the Customer
menu",  40.
Standard values for level measurements:
Primary vessel Measuring range
200 l 0 – 4 bar
300 – 500 l 0 – 10 bar
600 – 1000 l 0 – 25 bar
1500 – 2000 l 0 – 60 bar
3000 – 5000 l 0 – 100 bar

Note!
The weight measuring cell is not resistant to water hammer; also it must
not be painted!
7.4 Switching and make-up variants
7.4.1 Function
The current filling level is recorded in the primary tank by the "LIS" level sensor
and evaluated in the controller. The value for the minimum filling level is
specified in the controller's Customer menu. If the level drops below the defined
minimum, the "WV" make-up valve opens and fills the primary tank.
 Note!
To complete the make-up function from the drinking water system,
Reflex offers the Fillset with integrated system separator and Fillsoft
softening equipment,  4.6 "Optional equipment and accessories",

•
LIS Level sensor
Single boiler system ≤ 350 kW, water temperature < 100 °C.
• Connect the Reflex Fillset with integrated system separator upstream
when using mains water for make-up.
• If you don't connect a Reflex Fillset upstream, use an "ST" dirt trap with a
mesh size ≥ 0.25 mm for the make-up.

Note!
The quality of the make-up water must comply with the applicable
standards such as VDI 2035.

Variomat Basic — 09.09.2022-Rev. C
For gas-rich water from the system.
For degassed water into the system.
If you cannot achieve this quality, use the Reflex Fillsoft to soften
the make-up water from the mains water network.
