empty of water. Air pressure of 5 PSI minimum,
12 PSI maximum is recommended. The higher
the air pressure the smaller the volume of water
the tank will hold. Pressure of 10-12 PSI may be
necessary to feed a line to the refrigerator. Over
pressurizing may ruin the tank.

STEP 6 TUBING CONNECTIONS

IMPORTANT: Fitting manufacturer requires fit-
tings to be re-checked after system reaches full
operating pressure and temperature, Re-tighten
and secure as necessary.
It is not recommended to shorten the length of
any tubes during installation (except black 3/8"
drain tube on air gap faucet). This will make fu-
ture servicing easier.
1. ¼" White Supply Tube on Filter Pac/R/O mod-
ule: Connect the supply (white) tube firmly
into the push-in port on the side of the easy
tap adapter installed on the cold water supply
line. OPTIONAL: If self-piercing valve is used,
connect to valve using brass nut, tubing sup-
port, ferrule, and plastic insert (not included).
2. ¼" Red Drain Tube on Filter Pac/R/O module
- Air-Gap faucet system: Use the coupler from
the parts bag to connect the ¼" red drain tube
from the faucet to the red tube from Filter Pac/
R/O Module (See C in Figure 2 above). Push
firmly so tubes will not pull out of coupler or
leak. IMPORTANT: 1/4" red tubing MUST be
connected using the provided coupler or else
unit WILL NOT work properly.
3. 3/8" Black Drain Tube from Faucet: Connect
this tube to the black 3/8" drain clamp. (See D
in Figure 2). Tighten firmly so tube will not pull
out of drain clamp. IMPORTANT: Do not leave
excessive slack in drain tubing. Shorten tubing

NO DIPS IN LINE
so that it flows directly to the drain with no
dips, loops, low spots, or kinks. If not installed
correctly, water will be forced out the side air-
gap hole of the faucet.
4. Post Filter Connection to Faucet: KR10: Con-
nect the 3/8" blue tube on the front of the
post-filter bowl (labeled out) to the 3/8" push-
in adapter fitting on the R/O faucet. KR15:
Connect the 3/8" blue tube on the back of the
post-filter bowl (labeled out) to the 3/8" push-
in adapter fitting on the R/O faucet.
5. R/O Tank Connection: KR10: Connect the 3/8"
blue tube on the back of the post-filter bowl
(from the tee fitting) to the push-in ball valve
on top of the R/O storage tank. KR15: Connect
the 3/8" blue tube on the front of the post-filter
bowl (from the tee fitting) to the push-in ball
valve on top of the R/O storage tank.

STEP 7 SYSTEM START-UP PROCEDURES

Turn your sink cold water supply valve to the on
position while leaving the Filter Pac/R/O mod-
ule and R/O tank ball valves in the off position
(horizontal, which is perpendicular to the valve).
Check for leaks and adjust as necessary.
1. Slowly turn Filter Pac/R/O module ball valve
to the on position (blue valve vertical, which
is in line with the valve). As water enters the
filter bowls and makes its way through the fil-
ters to the membrane element you will hear
air escaping through the drain. This is normal.
Open R/O faucet on the sink until the water
starts coming out. (Water flow will only be a
trickle and may take up to 20 minutes before
water starts to come out of the faucet spout on
some units). Shut R/O faucet off and check for
leaks and adjust as necessary.
