Adjustment Methods
Make sure that the water route connections are correct, proper power supply is used and water supply is suitable.
Then, follow these steps to adjust the purifier:
•
Open the tap water inlet valve and the water purifier inlet water ball
valve and plug the purifier in the power outlet (See Diagram 14). Close
the storage tank ball valve, then automatically start a 120 second
flushing process, water will start to drain through the discharge outlet.
•
Wait for the water purifier to operate stably (for about 5-10 minutes).
Check each connection to make sure they are secure. Check to see if
there is any leakage from the membrane shell, filters, etc.
• Close the pure water osmosis faucet and storage tank ball valve. Wait
approximately 30 seconds. Check to see whether or not the water
purifier waste water and high pressure pump have stopped working.
•
Open the osmosis faucet. Check to see if the water is flowing through
the faucet. If not, check to see whether the tap water pressure is too low
or whether or not the high pressure switch can be reset automatically.
• Wait until the machine is operating properly, then close the inlet water
ball valve. After a short period of time, check to see if the machine stops
working, if it does not stop working, check to see whether or not
the low-pressure switch can be reset.
• Perform a second check to make sure everything is ok. Now your water
purifier is ready for use.
