INSTALLATION
STEP 1 Prepare for Installation
- Turn off COLD water valve. Release pressure from system by turning on dedicated faucet until water stops flowing.
- Unbox filter cartridge replacements and remove plastic.
STEP 2 Remove Filter Cartridges
- Remove Stage 1 and Stage 3 sumps from the system manifold by rotating the sumps to the left and pulling down.
- Holding the sumps over the sink, unscrew the top of the sump from the bottom by turning the bottom portion to the left. Pour excess water down the drain. Then, pull down on each filter cartridge to disconnect the filter cartridge from the top half of the sump.
- Discard both filter cartridges.
Note: If sumps are too tight to disconnect by hand, please use plastic
wrench provided with original system.
STEP 3 Attach Cartridges
-
Press new filter with clear netting to the top of Stage 1 sump. Reattach the bottom of the sump by ensuring connection points are correctly aligned, then turn to the right to tighten.
-
Continue this step for Stage 3 using the new filter with the blue netting.
Note: Do not use tools to tighten. Hand tighten only. -
Set aside Stage 1 and Stage 3 sumps and follow steps 4-5 to change the Remineralizer. To prevent water from flowing, do not reattach Stage 1 and 3 at this time.
STEP 4 Remove Remineralizer
- Remove the 3/8″ hose from the inlet and outlet of the Remineralizer by pushing and holding down the collar while removing the hose. Discard remineralizer.
Note: Be sure red tube and elbow are inserted all the way
STEP 5 Reconnect Tubing and Insert New Remineralizer
- Insert the white 3/8″ hose attached to the faucet into the outlet connection of the new Remineralizer by pressing the hose in until it stops.
- Connect the remaining hose end (which has the opposite end connected to the RO Manifold outlet labeled “Faucet”) to the inlet portion of the Remineralizer by pressing the hose in until it stops.
STEP 6 Reattach Sumps
- Reattach sumps to the system manifold with Stage 1 on the left and Stage 3 on the right to the top housing. Ensure all connection points are aligned. Push the top of the sump into the bottom of the top housing and turn the sump to the right. Ensure the sump is fully attached and locked into Stage 1 on the left and Stage 3 on the right.
Note: Ensure sumps are not on an angle while reattaching. This may result in damage to the o-ring.
STEP 7 Flush and Check for Leaks
-
Slowly turn on the cold water valve. Turn off the dedicated faucet and allow water tank to refill completely.
Note: It will take 2 hours for the water tank to refill. -
Once the tank has completely filled, inspect for leaks. If there are no leaks, flush the filter cartridges by turning on the dedicated faucet and allowing the water to run through the system until there is no pressure coming out of the dedicated faucet.
Note: Do not drink flushed water. -
Turn off the dedicated faucet and allow 2 hours for the pressure to build in the system. Once complete, your system is ready for use.
