Installation Instructions
Residential Reverse Osmosis Drinking Water System
Page 16
Icemaker hookup
(optional)
The RO drinking water device can be connected to any
standard refrigerator ice maker or ice maker/water dispenser.
3/8” tubing must be used for ice maker connections. If your
system is using 1/4” tubing for the tank and faucet it will need
to be changed to 3/8” tubing. (Do not connect to a commercial
type bar ice maker.)
To complete this operation, connect a tee with shutoff valve
into the faucet tubing (Blue Line) and route tubing to the
refrigerator. (Hooking up to an existing copper line is not
recommended as RO water can cause the copper to leach into
the water stream). Shut off ice maker prior to turning off the
existing tap water supply line to the refrigerator. Connect the
RO system tubing to the ice maker inlet. Turn on ice maker
after the RO system has been flushed several times and the
tank has a full supply of water. There are detailed instructions
and a layout drawing on Page # 22 and 23 of the is manual.
NOTE
: Before any service is performed on the RO system, turn
off ice maker valve and ice maker unit. Turn back on only after
RO tank has been flushed and is full of water.
System start-up
Prior to start-up
1. Check all connections to be sure they are secure.
2. Turn on feed water valve and check for leaks. (Turn off
and correct leaks if leaks occur.)
3. Close the valve (the tank should be closed from the
previous step) on storage tank and open faucet until a
steady stream of water flows. Water will be flowing to the
drain as well.
4. Once there is a steady stream of water coming from the
faucet (about 1/8” in diameter) close faucet and wait five
minutes to see if any leaks result on the entire system
(The initial water from the system may be discolored. This
is normal).
NOTE: BE PATIENT! It is very important that there is a steady
stream (not drips) of water coming from the faucet before it is
closed. If not, there could be air trapped in the system and it will
not fill the tank properly. This can waste a lot of water.
5. If there are no leaks, open the storage tank valve allow the
system to fill. Most systems will be full within 2 hours. The
system is full when the water to the drain stops. Check for
leaks with the system full and repair them accordingly.
NOTE: When the system is first turned on, water may
intermittently “spurt” from the air gap opening on the side of air
gap faucets. This is common and should correct itself after the
air is purged from the system.
Flushing system and checking operation
To make sure RO system is operating correctly, follow these
simple procedures:
1. Open faucet handle and allow tank to completely drain
(water will be discolored and will have suds from the
sanitizing solution).
2. Close faucet and re-fill the system.
3. Allow system to process water for approximately 2-3
hours, at which point tank will be practically full.
4. Open faucet again and allow tank to empty for a second
time. Do not use this water.
5.
Wait another 2-3 hours to allow tank to re-fill.
Air Purging
If the tank doesn’t fill, the tank tubing may have air in it.
Typically the standard startup procedure will be sufficient but in
some cases due to the water temperature and pressure,
additional air bleeding must be performed. The following
procedure will help bleed air from the system.
1. Close the tank valve and the feed water valve and open
the faucet to relieve the pressure on the system.
2. Remove the tank tubing from the tank valve and hold it
over a bucket or pan.
3. Open the feed water valve and the faucet.
4. Allow the system to run until there is a stream of water
coming from the tank tubing.
5. Once there is a steady stream coming from the tank
tubing, push it back into the tank valve. BE SURE to push
it in the tank valve completely or a leak could occur.
6. Allow the system to continue to operate until there is a
steady stream coming from the faucet.
7. Once there is a steady stream coming from the faucet,
close the faucet and open the tank valve. Then go to the
flushing procedure above.
NOTE: If no objectionable tastes are noticed after second tank
draining, RO processed water is ready for use. Otherwise, drain
tank and re-fill for a third time.
At this point supply line to ice maker connection (optional) may
be opened.
