Filter can remove a small amount of solid particles in liquid or air, can the normal work of the protection device and the air is clean, when the fluid is placed into a certain size of filter cartridge, the impurity is blocked, and clean flow through the filter out.
pure water machine filter replacement steps pre tertiary filter replacement methods:
this process typically have a water overflow, please prepare birdbath or cloth to clean appliance:
a) Turn off the electroplating ball valve and pressure ball valve barrel;
b) Open the gooseneck faucet to row residual water in the pipe,
c) After being water no longer flow, will be equipped with a filter shell wrench cartridge filter shell open;
d) Remove the old filter, loaded with new cartridge specifications;
e) Will be at the top of the filter shell black & other; O” Ring, coated with lubricant like vaseline, then & other; O” Ring into the filter shell in the slots.
) In vertical way, tighten the filter shell, as far as possible avoid let & other; O” Shift of the ring.
g) Open the electroplating ball valve and pressure barrels of ball valve.
replacement procedures and matters needing attention of RO membrane
this process typically have a water overflow, please prepare birdbath or cloth to clean appliance:
when you buy a new pure water machine, reverse osmosis membrane is usually in reverse osmosis membrane tube. Use for some time, when you need to replace the reverse osmosis membrane, you can ask professional service to you, or according to the following procedure to replace:
the preparation of the instruments: wrench, pliers, bucket, scissors or a knife.
note: in the process of installation/change, should try to avoid pulling to other pipeline, to avoid leaking.
change steps:
1, close the electroplating ball valve, wait ten minutes. ( Let the system pressure)
2, by hand or tool to unscrew the nut on the membrane shells the right joint, pull out pipe.
3, in the face of the machine, with his left hand held tight membrane shell, forcibly turned the end cap in hand. ( If the rear reverse osmosis membrane tube at the top of the active carbon filter interfere with the operation of this step, it can be a little bit shift or the whole pull out, if the whole pull out, is to open additional pipeline. )
4, close the ball valve, pressure barrels for hand or tool to unscrew the top of the nut joint, and tap into an empty barrels or sink.
5, with his left hand held tight reverse osmosis membrane tube, reoccupy pliers clamp old reverse osmosis membrane, it pulled up outside the membrane shells.
6, open a new reverse osmosis membrane envelope, to remove it.
7, a new reverse osmosis membrane in kaifeng into reverse osmosis membrane tube, until there are two small black & other; O” One end of the ring top to the bottom of the membrane shells.
8, to turn away membrane shell and cover the same posture, the membrane shell cover and tighten.
9, if necessary, in order to clockwise ( Lock) Adjust direction, joint point behind the machine.
10, into the pipe, and tighten the coupling nut. ( Remember to forget the pipes plug) 。
11, open the electroplating ball valve.
12 more than two hours, let the machine run, after normal water making system into the state, and then connect the pipes and pressure barrels of ball valve and ball valve opening pressure barrel.
