3) How to install waste water pipe and overflow pipe
Take out two suitable lengths of 1/4'' water pipe and connect them with the wastewater
into the sink drain pipe. Place the other ends of the wastewater pipe and overflow pipe just
inside the holes. Put some silica gel where the 6mm pipes and the drain pipe connect to prevent
leakage and use a cable tie to attach the wastewater pipe and overflow pipe to the drain pipe.
Notice: The highest point of overflow water pipe cannot be higher than overflow
outlet. Otherwise, water is not able to flow down.
4) How to install filter
First, take out water collector and remove two screws. Press
plastic padlock and dismantle panel of the unit. Unscrew the
1st, 2nd and 3rd filter cartridges from air purifier interior, and
install corresponding dense filter cotton and pre-carbon filter.
When the 2nd activated carbon filter is used for the first time,
some activated carbon powder from the activated carbon
filter will flow into the 3rd stage dense cotton filter or even RO
membrane, resulting in filter and membrane component
damage. So before installing dense filter cotton, place a
bigger container in the installation place of the 3rd stage filter
cartridge, then turn on inlet valve and switch, power on and
flush pre-activated carbon. When there is no black water
coming out, turn off power switch and install dense filter
cotton into the 3rd stage filter cartridge. (see Diagram 7)
Notice : Use a bigger container to hold water before installing the 3rd stage
super dense filter cotton. Install the 3rd stage filter until there is no black water
coming out.
5) How to install RO membrane
Take the water inlet pipe from the quick joint of membrane housing and unscrew the
membrane housing with its wrench. Then take RO membrane out of vacuum package and
install the end with four O rings into membrane housing tightly (see Diagram 8), in the end
install the housing cover and tighten it with cover wrench. Reconnect the water inlet pipe into
the quick joint of membrane housing and then lock the membrane housing clip into the large
single clip.
Warning:
Pay attention to RO membrane direction during installation;
Check whether one end of the membrane has 4 O rings or not when installing RO membrane.
If it is installed properly, RO membrane can be installed into membrane housing easily. if it is
difficult for membrane to install into it, don't insert RO membrane into membrane housing
violently which might cause permanent damage to membrane housing and membrane element
(The manufacturer is not liable for any damage to membrane caused by improper installation);
Damage to membrane housing and RO membrane caused by above-mentioned reasons is not
included in the warranty scope.
