Flushing the Filters
Important: This step is essential to protect the membrane from damage.
Ÿ
Disconnect the pipe from the filter housing located just before the membrane and temporarily connect a
length of pipe to this connector. The other end of the green pipe should be fitted to where the waste
water will be discharged.
Ÿ
Switch the water supply on.
Ÿ
Check seal for leakage and allow at least 2 UK Gallons of water to run through the system.
Flushing the Membrane
Ÿ
Turn the water supply off.
Ÿ
Remove the pipe from the carbon filter that has just been flushed.
Ÿ
Reconnect the existing pipe from the carbon to the membrane housing or pump if installed
Ÿ
Ensure that the Flush Valve in the green pipe at the top of the system is in the “Flush” setting. Turn the
supply water back on at the saddle valve and allow the system to run until 5 gallons have been
discarded.
Ÿ
Now turn the Flush Valve to “Production” and run until 5 gallon of production water has been produced
Ÿ
Check the complete system for leaks throughout this period.
Ÿ
You have now flushed the membrane.
Important: Do not use the first 5 gallons of water. This process is to remove the sanitizing solution
from the entire system.
Connecting the DI Unit
Ÿ
After you have run 5 gallons of production through the system turn off the feed water and insert the blue
pipe at the back of the unit into the DI unit. Assemble the system back together and run another two
gallons of production water. Test the TDS after the water has finished running and you should now get
a low reading.
Ÿ
Please note you should use a TDS meter to accurately indicate when to change the Deionizing Resin.
Failure to change the resin when the TDS starts to rise will cause the resin to unload unwanted
contaminants back into the product water.
Startup Procedure
Ÿ
Once everything is connected, switch on the water to check for leaks.
Ÿ
After initial flushing, open the shut-off valve on the tank and close the sink top faucet. ( Domestic &
Dental Systems only)
Ÿ
Tank will now fill (Usually 2 to 3 hours) After the tank has filled, open the sink top faucet and drain all
the water until the storage tank is empty and there is only a small flow from the sink top faucet.
Ÿ
Close the sink top faucet. The system is now ready for use.
