nstallation Steps for Zero Waste Reverse Osmosis Retrofit Kit
Note: RO unit must be installed a mimimun of 25 feet from hot water heater.
Step 1
Turn off the hot (#1 in Fig. 1) and cold (#2 in Fig. 1) water supply lines to the sink at the angle
stop valves. If system is hooked up to an ice maker close the valve to the ice maker.
Step 2
Drain tank by opening the RO faucet (#3 in Fig. 1).
Step 3
Disconnect the standard hot water sink faucet supply line and install the included water supply
valve to the hot water angle stop (#4 in Fig. 2). Then reconnect the standard sink faucet supply
line to the included water supply valve. If the standard hot water sink faucet supply line does
not disconnect from the hot water angle stop, the included hot water supply valve will have to be
installed at the hot water sink faucet fitting (#21 Fig. 2).
Step 4
Remove waste water tube on membrane housing (#5 in Fig. 1).
Step 5a
If system has an air gap faucet,
cut the air gap inlet tube approximately 6” from the faucet
connection ( #6 in Fig. 1). This tube will not be reconnected to anything.
Step 5b
If system has a non air gap faucet,
disconnect at drain saddle (#7 in Fig. 1) and use the plug
provided to seal opening where the tube was connected with drain saddle.
Step 6
Attach the short tube of the new flow restrictor assembly on the membrane housing at #8 in
Fig. 2).
Step 7
Attach the long tube from the flow restrictor assembly to the hot water supply valve (#9 in Fig.
2).
Step 8
Remove the inlet water tube going into the membrane filter vessel (#10 in Fig. 2).
Step 9
Attach the tube from the solenoid (#11 in Fig. 2) to membrane inlet (#10 in Fig. 2).
Step 10
Remove the outlet tube coming from the last prefilter bowl’s lid (#13 Fig. 2).
Step 11
Attach the new tube that is attached to the pump inlet (#12 Fig. 2) to the outlet of the last
prefilter bowl’s lid (#13 in Fig. 2).
Step 12
Mount the solenoid and pump in a convienant location. Be sure that the tubes are not kinked.
Step 13
Locate the outlet of RO water from membrane filter vessel (#14 in Fig. 1). Cut the tubing at the
shut off valve (#15 in Fig. 1).
Step 14
Locate the tube going to the tank (#16 in Fig. 1). Follow it back to automatic shut off switch and
cut the tube at the shut off valve (#17 in Fig. 1).
Step 15
Insert the tube from step 13 by pushing it into the connector on the side of the pressure switch
(#18 in Fig. 2). Insert the tube from step 14 into the connector on the other side (#19 in Fig. 2).
The switch has a quick disconnect fittings which require the tube to be inserted and pushed
firmly into the fitting. To disconnect, push on the plastic ring while pulling the tube.
Step 16
All Electrical connections are color coded for your convenience. Connect the transformer to
the wiring harnesses (#20 in Fig. 2).
Step 17
Turn on the hot and cold water supply lines (open ice maker valve after tank has filled, if con-
nected to an ice maker.) Check for leaks and tighten fittings as needed.
Step 18
Plug the transformer into an electrical outlet (not the garbage disposal outlet) and let the unit run for
two minutes. Check for leaks and tighten fittings as needed.
Step 19
Periodically check unit for leaks during the first 5 days of operation. If leaks develop, please shut off the
unit by closing the small valve on the angle stop valve and call customer service for troubleshooting.
