Changing Stage-5 Carbon TCR Filter: (should be changed every 3-5 years with Membrane)
1) Remove the OLD filter: See Fig. B. Disconnect the Input tubing from point J and Output tubing from
point H. To remove the tubing, Push In and hold down on the collet ring square against the fitting. With the
collet held in this position the tube can be removed. Unclip the filter from the membrane housing and discard
the used filter.
2) Sanitize: Use some mild bleach solution to rinse the 2 tubing ends, and the 2 ports of the new filter. This is to
prevent contamination.
3) Install NEW Filter: Put the filter back onto the membrane housing. Make sure the “FLOW ” on the filter is
pointing to the pure water output direction.
NOTE: The QC filter will come with 2 end plugs.
Please remove both end plugs before
reattaching tubing. See Fig. C.
4) Connect the Tee fitting on the Inlet (J) of the filter. Push the tubing into the QC fitting on the filter, then gently
pull back on make sure connection was secure. Lastly connect pure water output line to Outlet (H) on filter.
5) Check for leaks!
