NOTE:
A drinking water cartridge may contain carbon fines
(very fine black powder). After installation, flush the cartridge
for 5 minutes to remove the fines before using the water. It is
recommended that you run the tap at least 20 seconds prior to
using water for drinking or cooking purposes.
NOTE:
Initially, filtered water may appear cloudy. If you set a
glass of water on a level surface, you should be able to watch
the cloudiness disappear from the bottom of the glass upwards.
This harmless cloudiness results from the release of trapped air
within the cartridge and will disappear within a few weeks after
installation.
Troubleshooting
Leaks between cap and bottom of filter housing
Turn off water supply and turn on drinking water faucet to release
pressure in system. Remove bottom of housing. Clean o-ring and
o-ring groove (located directly beneath threads of housing). Lubricate
o-ring with silicone grease and replace securely into groove. Screw
bottom of housing onto cap and hand-tighten. DO NOT OVER-
TIGHTEN. Turn on water supply and check for leaks.
Leaks on system inlet/outlet connections
Turn off water supply and turn on drinking water faucet to release
pressure in system. Remove tubing from fitting and make sure end of
tubing is cut squarely and free of burrs. Reinsert tubing into fitting,
making sure to push tubing to a hard stop. Hand tight compression nut
first, then tighten 1 to 1
1
⁄
2
turns for new compression nut. Tighten only
1/2 to 1 turn with wrench for previously tightened compression nut.
Leaks on faucet/tubing connection
Turn off water supply, then turn on drinking water faucet to release
pressure in system. Loosen and remove compression nut fitting on
faucet stem. Make sure tubing is inserted firmly into end of faucet
stem, then retighten compression nut with fingers until secure. Turn
on saddle valve, then turn off faucet to check for leaks.
NOTE:
If leaks persist, or if there are other leaks on system, turn off
water supply. Call our Technical Support Department at 920.451.9301.
Low Water Flow
1. Check flow at faucet. The AS-301E system should fill a gallon jug
in approximately 2 minutes (1 liter in 30 seconds). Flow rates will
vary with individual household water pressure.
2. Check filter cartridge installation. Make certain all filter cartridges
are properly oriented in filter housings.
3. Check flow through empty system. To do this, turn off water
supply and press the red pressure relief button. Then remove filter
cartridges from housings and screw housings back onto caps.
Turn on faucet to check flow through empty system. Flow should
be about one to two gallons per minute. If flow is less than 1.5
liters per minute, call Technical Support at 920-451-9301.
4. If flow through empty system is adequate, place one filter
cartridge in system at a time and check flow to make sure
cartridge is not clogged. Replace clogged cartridge if necessary..
