Installation and maintenance
Installation notes
To avoid installation errors, please read the following instructions carefully.
•
As the control components are controlled by electronic circuits, a three-day power failure (72
hours) or an intermittent power supply may cause the time shown on the control valve display
panel to result in an incorrect backwashing time for the water treatment device (check the time
shown on the control valve panel and the actual time after continuous operation of approxi-
mately 3 months). After restoring the power supply, check whether the time displayed on the
control panel is correct. If this is not the case, refer to the instructions to find out how to set the
water treatment device clock.
•
If the water pressure of the water treatment device is lower than the specified operating pres-
sure, install a booster pump, which should be installed at the front of the water inlet of the water
treatment device. At the same time, the outlet pressure of the booster pump must not exceed
4.5
bar, otherwise a pressure-reducing valve must be installed between the booster pump and
the water treatment device. WilTec GmbH is not responsible for detrimental effects and damage
caused by an excessively high outlet pressure of the booster pump on the water treatment de-
vice.
•
If the main water supply is interrupted, the main valve of the supply line should be closed im-
mediately or the bypass valve of the water treatment device should be switched to the bypass
state to prevent the water treatment device from being damaged by the negative pressure in
the pipework caused by the municipal water supply.
•
When the main water supply is restored, a large number of pollutants in the water pipe contam-
inate the treatment device. Therefore, first switch the bypass valve of the treatment device to
the bypass station, open the tap in the house, and drain the water from the dirty water supply
station.
•
The water treatment device must not be tilted or laid on its side during transport, installation or
use.
•
The floor on which the water treatment device is installed should be level and have a load-
bearing capacity of more than 300
kg
⁄
m
. In addition, an AC power supply, a water inlet and outlet
interface, a waste-water pipe, and a floor drain should be available.
•
Installation area:
o
CF-M1-C: 380 × 440 × 595
mm (L×W×H)
o
CF-M1: 380 × 440 × 640
mm (L×W×H)
o
CF-M2: 380 × 440 × 1140
mm (L×W×H)
•
Do not install the treatment device near acidic and alkaline substances or near gases to avoid
corrosion on the treatment device.
•
The water treatment device must be installed indoors. Measures must be taken to insulate the
housing and pipework, in particular to protect against frost and solar radiation and for sealing.
•
It is forbidden to install the treatment device on a water pipe with a water pressure of more than
4.5
bar. If the water inlet pressure exceeds 4.5
bar, a pressure-reducing valve must be installed
(to be purchased separately), otherwise the company accepts no responsibility for conse-
quences such as impairment or damage to the water treatment device due to excessive water
inlet pressure and any resulting damage.
•
The water treatment device should be installed and used in a room with a floor drain and smooth
drainage. If the drain pipe or floor drain is blocked and the drain pump cannot drain normally
due to a power failure or other malfunction, please close the building’s main water inlet valve
immediately. At the installation site, it must be ensured that objects in the neighbouring area or
in the part of the building below are not damaged or flooded if water escapes from the water
treatment device or the connection pipe. WilTec GmbH is not responsible for detrimental effects
and damage caused by a fault of the drain or a wrong installation.
•
As shown in the illustration below, the drain pipe and the overflow pipe must be secured with
ring clamps to prevent leakage during water drainage.
