Installation checklist
①
When you use a measuring instrument: Measure the pressure of raw water with a measuring
instrument and if the water pressure is low then please adjust the water pressure by using the water
pressure controlling valve.
②
When you do not have a measuring instrument (A simple measuring way):
If water can be filled in the vending machine cup during 6~7 seconds, the water pressure is
about 1.8
ℓ
/min and it is the proper water pressure for operating the machine.
If the water pressure is too low or high, the buzzer will be sounded, when you drain the water.
The machine will sound the warning, if the water pressure is lower than 0.5liter, higher than
3.5liter. When you install the machine for the first time, turn on the machine with closed water
pressure controlling valve, and then slowly open the valve to adjust the water pressure.
(The proper water pressure for the normal operation is 1.5~3.0kgf/cm

How to check the water pressure and set up
■
If the quality of groundwater is bad, you must mount a preprocessing filter.
■
In the area which has high solidity and calcareous, there is soiled as white by the calcium,
so in the middle of water flow, you push the acidic water button 2~3 times in the week and
drain water during 30~60 seconds.
The case that ground water or solid quality of water is used
Water pressure is too improper.
■
If the water pressure is too low, then there will be too much acidic water and not enough
alkaline.
■
Depends on the fluid pressure and fluid speed, there would be several changes,
so it’s not a failure of machine.
■
Check to make sure the draining hose isn’t bent or kinked.
If it is, there won’t be enough acid water and the alkaline water will be weak.
If there is an improper ratio of alkaline water and acidic water
