TROUBLE SHOOTING

Cause
Low Water Pressure
Crimps in tubing
Clogged pre-filters
Fouled membrane
Air in system
Low water pressure
Fouled membrane
High water pressure
High air pressure in tank
Air gap faucet
Location of drain saddle
Higher capacity membrane
High water pressure
Crimp or loop in drain line
Drain tube clogged/restricted
System just starting up
Low water pressure
Too much air in tank
Not properly tightened.
Missing or kinked O-ring
Solution
Assure a minimum of 40 psi incoming water pressure.
Premier sells a booster pump if home water pressure is
low. Maker sure water supply is turned on and Adapta
Valve is all the way open
Check tubing and straighten or replace as necessary.
Replace pre-filters.
Replace membrane and clean flow restrictor.
Air in the system is a normal occurrence with initial start
up of the RO system. This milky look will disappear
during normal use within 1-2 weeks. If condition reoccurs
after filter change, drain tank 1 to 2 times.
See #1 Above
Replace membrane
Check incoming water pressure to make sure it does not
exceed 100psi. A pressure relief valve may be necessary.
Empty storage tank of water. Set tank air pressure to 5
psi. See Page 15.
Inherent sound with air-gap faucets.
See diagram for proper location of drain saddle.
Normal with high capacity membrane
Check incoming water pressure to make sure it does not
exceed 100 psi. A presser relief valve may be necessary.
Straighten black 3/8 drain tube. Cut off any excess tubing
Caused from dishwasher or garbage disposal.
Disconnect the 3/8" black tube at the drain, clean the 3/8"
black tube out with a wire, then reconnect.
Normally it takes 4-6 hours to fill tank. Note: Low water
pressure and/or temperature can drastically reduce
production rate.
See #1 Above
Add air if below 5 psi and bleed if above 5 psi. Check
only when tank is empty of water. See Page 15.
Tighten the bowl
Turn off the water supply. Release the pressure, remove
bowl and replace the O-ring. (p/n 113043). Make sure
the O-ring is seated in the filter bowl properly before
reinstalling the filter bowl.
