If an operating room is available, it is recommended to use the installation method shown in Figure 3.
Otherwise, the drain pipe can only be inserted into the floor drain. As shown in Figure 4, make sure that
the two pipes are fixed to the wall to prevent the pipe from being flushed out of the floor drain when
emptying. This can have detrimental effects and lead to damage.
Install connections
•
The connection and laying of the pipe system is carried out in accordance with the provisions
of the construction standards for water supply and drainage pipes. The inlet and outlet interfaces
of the water treatment device and the water pipe interfaces are connected by a ¾″ PPR inner
pipe or a corrugated pipe and must be installed on the same axis (see installation plan). The
inlet and outlet points must not be installed in reverse.
•
Connect the water inlet and outlet pipes, the drain pipes, and the overflow pipes in sequence to
ensure that all connections are tight and that there are no leaks. It is recommended to use
flexible pipes to connect the water treatment device inlets and outlets, the drain, and the over-
flow (note: 304 stainless steel, alloy forged steel, high-strength engineering plastics, and other
materials are to be used for the connection of pipe fittings and valves; valves and pipe fittings
made of iron are strictly prohibited).
Installing the drain and overflow pipes
•
First loosen the clamp and insert it into the pre-fixed pipe, then insert the pipe into the drain
connection to the floor, and finally turn the clamp onto the connection of the pipe and drain
connection and tighten it firmly. The drain pipe must be secured with a clamp. (
Note!
This pro-
cedure is intended to ensure that the hose is not pushed away or pushed out of the sewer if the
flat is connected to the sewer or the water pressure of the floor drain is high).
•
The position of the control valve must be higher than the floor drain and the length of the drain
pipe must not exceed 2 m. The installation of shut-off devices in the drain pipe is strictly prohib-
ited. The sealing of the pipe fittings may only be made of PTFE.
Instructions for first use
1.
Initial settings of the operating system
When the treatment device is switched on for the first time, the system indicates that water is
being added. Press the button to access the operating system and set the current time and
rinse time.
2.
First water supply for water purifiers
Before the first water supply, close the water inlet valve of the building and switch the valve to
the “water supply” operating mode. Unlock the system, press the button to start backwashing;
“system is backwashing” appears on the display panel. Open the water inlet valve slowly to ¼
(opening it quickly can damage the appliance and lead to loss of activated carbon). At the be-
ginning, the sound of slowly escaping air should be heard in the drain pipe. After the air in the
GFK tank has escaped (i.e., when the water in the drain pipe flows out evenly), the water inlet
valve should be fully opened.
Attention!
If the water inlet valve is fully opened directly, the water will flow into the purifier too quickly,
causing the activated carbon in the tank to be stirred up, which will easily cause damages. It is therefore
necessary to open the water inlet valve slowly ¼ to allow the water to flow slowly into the tank, release
the air in the tank and fill the tank with tap water. During backwashing, the water flowing out of the outlet
pipe must be checked several times until it is really clean. The backwash time should not be less than
5
min.
