CHANGING THE CO2
CANISTER
When the sparkling water tastes flat, it is
necessary to change the gas canister. The
integral CO2 gas canister is sited on the left-
hand side at
the front of
the unit.
1. To remove a canister,
unscrew in a counter-
clockwise direction.
2. Locate the thread on the
regulator where the gas can-
ister will connect.
3. Carefully present the canister, ensuring the
canister is supported.
4. Rotate the canister in a
clockwise direction, being
careful not to cross-thread the
regulator.
Please follow the instructions below to
ensure your CO2 canister is correctly in-
stalled:

5. Rotate until you hear a
hissing sound. This is the gas
being released from the
canister. It is important to
keep screwing until you can
no longer hear this hissing.
6. When the canister
cannot be turned fur-
ther, it is safely con-
nected. Do not turn
the canister any fur-
ther, as this will dam-
age the regulator.
7. Press the glass icon button and runoff an
amount of sparkling water to re-calibrate the
system.
8. It may be necessary to readjust the pressure
regulator located above the CO2 canister to
get the appropriate CO2 mix in your water.

The filter should be changed at least once
a year or if the taste or smell of chlorine is
evident. The GAC
filter is located
in front of the
water heater on
the right side. It is
inside the stain-
less steel canis-
ter. Please follow
these instruc-
tions to ensure
the GAC filter is
installed correctly.
3. Turn off the power supply to the water heater
by either unplugging the water heater or
using the toggle switch located on the back
of the water heater.
1. Turn off the cold water supply to the water
heater.
5. Unscrew the canister in a counter-clock-
wise direction until it is clear of its threads.
6. At this point, you can access the filter. Un-
screw the filter in a counter-clockwise direc-
tion. You can now remove both the stainless-
steel filter housing and GAC filter from the
water heater.
2. Relieve pressure in the system by touching
the chilled water icon TouchTap™ or button
SmartTap™ and wait until the water stops
coming out of the faucet.
4. You may want to
put a towel under
the stainless steel
canister that holds
the GAC filter to
prevent water from
spilling on the floor
of the cabinet.

8. Reinstall the filter housing, being very care-
ful not to lose or damage the O-Ring in the fil-
ter housing. If the O-Ring is damaged, replace
it before reinstalling.

ter back on. Turn the cold water on and touch
the chilled water icon (QT) or button (QST).
Let the water run for sixty (60) seconds to
expel any air in the system.
7. Remove the old filter and replace the new
filter in the canister. Position both stainless-
steel filter housing and filter so that you can
screw the filter into its manifold.
9. You can now turn the power on to the wa-
ter heater, and your system is ready to be
used.
