Depending on which model was purchased the chart below will assist with placement of filter
cartridges.
Note: Use the Filter wrench supplied with RO system
Step 1 Turn off the incoming water supply to the RO by turning the ball valve clock wise until it stops.
Step 2 Close the holding tank valve.
Step 3 Open the RO faucet and allow water to drain to release system pressure.
Note: Water may be saved in a container for drinking or to rinse system parts.
Step 4 For more leverage you may leave the RO unit attached to the wall of the cabinet. If you are
unable to access the unit while it is mounted, remove it prior to changing filters. Starting with the
closet housing stage 1, remove it by turning it clockwise (left), empty water, then discard filter.
Continue on the 2nd housing (Stage 2) and 3rd housing (Stage 3).
Note: The 3 stage RO system has to two vertical housings, 4 & 5 stage RO system have three
vertical housings.
Step 5 Clean the filter housings bowls with a mild soap solution and rinse with water. Check the O-ring
and lubricate with water only. Do not use petroleum based lubricants such as Vaseline.
Note: Before re-installing the filter bowls back on the system, check O-rings to make sure they still
are in place.
For Model VRO-3:
Step 1 Insert a 5 micron Carbon Block filter (white end cap and plastic netting) into the 1st filter housing
which is the one on the water inlet side (white tubing) of the RO system and re-install housings.
Step 2 Insert a 5 micron Carbon Block filter (white end cap and plastic netting) into 2nd filter bowl and
re-install housings.
Skip to Step 6.
For Model VRO-4:
Step 1 Insert a 5 micron Sediment filter (cloth like appearance) into the 1st filter housing which is the
one on the water inlet side (white tubing) of the RO system and re-install housings.
Step 2 Insert a 5 micron Carbon Block filter (white end cap and plastic netting) into 2nd filter bowl and
re-install housings.
Skip to Step 6.
For Model VRO-5 and VRO-5WP:
Step 1 Insert a 5 micron Sediment filter (cloth like appearance) into the 1st filter housing which is the
