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.

Operation Warnings

• The major components of this product are manufactured using plastic.
When using the water purifier, always observe the integrity
of the equipment in order to ensure safe operation.
• The package of the reverse osmosis membrane contains a small amount
of protective solution in order to prevent microbiological contamination
of membrane components during storage and transportation. The
PAC filter may emit activated carbon powder the first time it is used.
So do not open the water storage tank during the first hour when the
water purifier is put into operation. It is recommended that the water
produced during this period is disposed of. Otherwise, the taste of the
pure water may be unusual.
• When you first use the storage tank it is recommended that you discard
the first tank of water; otherwise it may result in abnormal tasting pure
water.
• When you first operate the water purifier, the pure water TDS value may
be a little high. After operating for some time, the TDS value of the pure
water produced will gradually decrease until it is stable.
ENG 14
• 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.
Inlet water valve
Close
• When you are using the water purifier, the inlet water ball valve should
be opened and the pure water faucet needs to be turned on. When
you are not using water turn off the water faucet, the high pressure
switch will automatically cut off the water supply.
• When the unit is not operated for long periods of time, occurance of
microbiological contamination is possible.
To prevent any microbiological contamination, it is recommended to
operate the unit at least twice a week. Otherwise, the water can have a
smell.
• When any of the following situations occur, immediately disconnect
the water purifier water source (close the inlet water ball valve) and/or
the power source and carry out repairs.
- If the water purifier pipes or related components are leaking.
- If the water purifier and/or components stop working.
- If any components leak electricity.
- If there are any other anomalies or failures.
