Installation And Assembly; Hydraulic Installation - BWT bestaqua 14ROC Einbau- Und Bedienungsanleitung

I
CAUTION!
If the pressure exceeds 0.4 MPa (4.0 bar), then a pressure reducing valve must be installed.
f
If the pressure drops below 0.15 MPa (1.5 bar), then a pressure booster system must be
f
installed upstream.
We recommend installing a shut off valve at the inlet side of the device to enable the feed-
water flow to be interrupted for service purposes.
Installation should use at least DN 10. Smaller feed pipes may result in operational
stoppage due to insufficient water pressure or flow (e.g. when flushing the reverse osmosis
membranes).
Installing a pressure reducer may reduce the flow rate.

2 Installation and assembly

Unpacking the RO device:
Remove the device from the packaging and check that all components are included and
undamaged.

Hydraulic installation:

▽
ATTENTION!
Observe the general installation regulations for creating water installations and the general
f
hygiene conditions.
Read the technical data, operating notes, and safety notes first and observe them during
installation.
Use only flexible hoses approved under DVGW W 543 to connect the device.
Observe the installation dimensions and bend radii when installing accessories (such as hoses,
connection sets, etc.).
The device bestaqua 14ROC is to be set up and operated with installed magnet plates.
The device may not be hard plumbed to the water supply network, e.g. copper or brass.
C
onnecting to the water pipe:
The hoses of the device are to be connected free of tension.
Verify that connections are watertight.
The concentrate line is to be connected to the wastewater connection with an approved air
gap. Check that flexible hoses are free of any restrictions. During installation, ensure that the
concentrate and permeate lines are correctly connected.
 NOTE!
Before using the RO unit, we recommend checking the water pre-treatment (e.g. in-house
f
softener, central water processing of waterworks). This measure is necessary to improve the
efficiency and service life of your RO membrane.
Please discard the permeate produced during the first ten minutes after installation, initial
f
start-up, or membrane change.
Reduction of the temperature by 1 °C results in a reduction of the permeate output of the
f
membranes by approximately 3 %.
Connect the RO device to a grounded mains socket (100-230 V, 50 Hz).
Please observe the provisions in the operating manual of the external pre-filter used.
As a general rule, we recommend using softened water to extend the service life and
operational safety of the RO membrane.
Connect all hoses and check for water leaks.
Open the inlet valve for the feedwater supply.
Connect the mains plug (230 V/50 Hz) to the power supply.
