Installation Instructions
Flush and Start Water Purifier
The water purifier must be flushed manually and automatically at the first installation and
replacement.
1) Manual flush:
Pull out the threaded flow-limiting plug in the wastewater outlet (clean the groove if it is
dirty). Plug in the power, turn on the water inlet valve and small ball valve, and flush for
about 2-5 minutes. Turn off the small ball valve.
2) Automatic flush:
Install the threaded flow-limiting plug into the wastewater pipe. Open the small ball valve
to produce water. Meanwhile, open the water faucet to exhaust the air. Wait until the
water faucet is exhausted completely, and close the faucet after the water flow is steady.
After the storage tank is full in about 45~60 minutes, open the water faucet to discharge
all the water in the storage tank.
3) Check the tightness at various each part of the product carefully when flushing. Wipe
all the connections with tissue paper to see whether it is wet.
Check whether all the water pipes are installed correctly and completely.
4) Confirm that the flushing is complete, turn off the water faucet and complete the
commissioning.
