13. Install Icemaker Hookup (optional)
The RO drinking water fi ltration system can be connected to any standard refrigerator icemaker or ice-
maker/water dispenser. It should never be connected to a commercial type bar icemaker.
Hooking up an icemaker involves connecting a tee with shutoff valve into the blue 3/8” faucet tubing and
routing tubing over to the refrigerator. Hooking up to existing copper tubing is generally not recommended.
If copper tubing must be used, then installation of a small in-line carbon fi lter at the refrigerator connection
is recommended.
Before turning off the existing tap water supply to the refrigerator icemaker, always shut off the icemaker fi rst
(usually by lifting the lever arm above the bin to the uppermost position). The icemaker should only be turned
on again after the RO system has been drained several times and the tank has a full supply of water.
NOTE: High capacity residential refrigeration icemakers (e.g. Sub-Zero ® ) may require a minimum pressure
of 20 psi (138 kPa). In some instances, this unit will not provide 20 psi (138 kPa) or greater pressure. In that
case, a second storage tank will be required. Please call technical services for installation advice.
14. Install Filter Cartridges
A) Remove new fi lter cartridges from the box.
B) Using tap water, wet the o-ring seals to make insertion easier.
C) Line up the cartridge ears, insert cartridge and push into the head until fully seated. Twist the cartridge
1/4 turn to the right (clockwise) to lock into place.
15. Start Up The System
A) Double check that all connections are secure.
B) Turn on feedwater saddle valve and check for leaks. If any leaks are noted, turn off valve and correct
before proceeding. NOTE: If a leak occurs at a “Push-In” fi tting, refer to Figure 4 on page 17.
C) Lift faucet handle and allow tank to drain completely of sanitizing solution. Do not use this water. When
tank is empty, the faucet will steadily drip. This is the rate water is processed by the RO system. Ap-
proximately 2-3 drops per second.
D) Close faucet. Wait at least 4 hours and drain tank again. The water should be discarded as it may con-
tain some disinfectant solution.
E) The system should be ready to use as soon as the tank refi lls. If any objectionable taste is noticed after
the second tank draining, wait and drain tank the following day. Only when the tank is full should an
icemaker be turned on if one is connected to the system.
NOTE: When the system is fi rst turned on, water may intermittently “spurt” from the air gap module. This is
perfectly normal and is caused by air trapped in the system. This will usually disappear within a short time.
• Before any service is performed on the RO system, always turn off the icemaker valve and the icemaker unit.
Only turn on when the system is operating and the tank is full.
IMPORTANT NOTES
To reduce the risk associated with ingestion of water contaminated with Calcium Hypochlorite sanitizer:
• After installation, sanitizer must be fl ushed from the system before fi rst use as directed within the installation
instructions.
To reduce the risk associated with property damage due to water leakage:
• Ensure all tubing and fi ttings are secure and free of leaks.
