Water
Input
Drain Water Outlet
Drain water outlet Tube
Tap water supply tube
Close the cold water supply:
- Turn the shut-off valve located under your sink clockwise.
Release pressure:
- Once the cold water supply is closed and there is no flow to the faucet, open the flow of cold
water from the sink faucet (lift faucet as if to run cold water) to release any pressure.
Disconnect feedline from under sink to the sink faucet:
- Spin the riser nut from the existing cold water shut-off. This disconnects the water feedline from
the faucet.
Attach T-Valve to water inlet feedline:
- With the water inlet shut off valve remaining closed, screw the T-Valve (from Install Kit) onto the
cold water inlet feed.

13
How to Install the Product
Connect the sink feed line to T-Valve:
- Connect the nut (from the sink faucet feed line) to the open end of the T-Valve and tighten. Make
sure the connection between the T-Valve and sink feed line is secure.
Connect ¼” Water Line:
- Locate the "tap water inlet" on the water filtration unit and insert the 1/4" tubing (from install kit),
connect the other end of the 1/4" tubing to the T-Valve quick connect connection. Make sure both
connections are secure.
Reverse Osmosis Drain Line and Saddle Valve:
-
Reverse osmosis filters require a drain line be connected from the RO membrane to a drain pipe.
Locate a horizontal or vertical section of drain pipe (wastewater from the sink) under the sink
before the p-trap and away from the garbage disposal. The saddle valve is installed to hold this
drain line connection firmly onto the drain pipe.
Saddle Valve:
-
Place the saddle valve (from install kit) in the selected location of drain pipe. Mark the area where the saddle
valve has its 1/4" opening on the drain pipe.
Drill Drain Line:
- Drill a 1/4" hole through the marked area that represented the opening of the saddle valve. Only
drill through one side of the drain pipe, do NOT drill all the way through the other side of pipe.
Line up Saddle Valve:
- Arrange the saddle valve onto the drain pipe so that the 1/4" hole you drilled matches up with the
1/4" hole in the saddle valve. Use a bit of the water line tubing or a drill bit to ensure the holes are
aligned.
Secure Saddle Valve:
-
With the holes still aligned, secure the saddle valve clamps in place. Make sure the hole are still aligned before
tightly securing the saddle valve nuts.
Connect Drain Line:
-
Secure the second ¼” water line in the saddle valve opening (to the drain line) on one end, to the
external output of the water cooler on the other end. Make sure the connections are secure. The drain
line (from water unit) should be fully into the drain pipe and secure.
Double check all connections:
- Check all water line connections to ensure they are secure
Turn on Cold water:
- Reopen the cold water inlet valve by turning counter clockwise. This will allow water flow through
the attached water line, into filters and to the water unit. CHECK THERE ARE NO LEAKS
Flush Filters:
- Allow the water tanks to fill completely and empty the contents to flush the unit. Complete this
process twice. The water level indicators will illuminate brightly when tank is full.
Turn on Hot/Cold Function
-
After flushing the filters and unit, allow the hot and cold water tanks to fill completely. Once full,
you may turn on the hot and cold buttons on the unit to heat and cool the purified water.
*It is very important to allow the tanks to fill completely before turning the hot/cold on.

Recommended Filter Replacement Cycle
The filter replacement cycle is determined with the use of 10 L, and
may be affected by the condition of tap water.
Recommendations
Filtration Capacity
Filtration capacity is the recommended amount of usage by the rate of removal of
chloroform etc. This is to get the life span of of the filters in the purifier.
Filter Replacement Cycle
The filter replacement cycle means the expected cycle (period) that the filters can
perform properly.
The filter replacement cycle may vary based on usage. Its standard cycle has been set
under condition that the supply is tap water with about 10L (drinking water (for four
people) used per day.
In the reverse osmosis membrane filter system, the water purified
through
the filter is 20~35% of the raw water (Water temperature 25℃, Water Pressure 0.34
MPa). This can vary depending on water temperature and water pressure.
