Important:
Check air pressure only when the tank is empty of water!
Check air pressure in the storage tank when you notice a decrease in available water from the RO system.
Air can be added with a bicycle pump using the valve that is located on the bottom of the tank cover by a
black cap.
Step 1 Turn off the incoming water supply to the RO by turning the needle valve counter clockwise until it
stops. Follow the white tubing from the RO system to the intake water valve location.
Step 2 Open the RO Faucet and allow the water to drain from the tank until it is completely empty.
Tip:
When water from the RO faucet slows to a trickle, with the faucet still in the open position, you
may add air to the tank to purge any left over water, this will ensure that the tank is completely
empty.
Step 3 Once all the water in the tank is purged, check the air
pressure using an air pressure gauge,it should read
between 5 to 7 psi. (Digital air pressure gauge is
recommended)
Step 4 Follow start-up procedure on page 14.

RoCeduRe foR
Turn off water supply by turning the RO intake water valve in a counterclockwise direction until it stops and
open the RO faucet to empty the storage tank. Once the storage tank is empty, remove the membrane and
place it in a sealed plastic bag and store in the refrigerator.

Air Gap Faucet
Location of drain saddle
Restriction in drain line
System just started up
Air pressure in storage tank is low
Low water pressure
Crimps in tubing
Clogged pre-filters
Fouled membrane
Post carbon filter is depleted
Fouled Membrane
Sanitizer not flushed out
Clogged flow restrictor
Fittings not tightened
Missing O-ring
Misalignment of hole in drain saddle

SOLUTION
Air in the system is a normal occurrence during
initial start-up of the RO system. This milky colour will disappear during
normal use within 1 to 2 weeks.
Inherent sound with an air gap faucet
Relocate the drain to a horizontal location
Clear blockage that is sometimes caused by
debris from garbage disposal unit or dishwasher
Normally it takes 4-6 hours to fill the RO tank. Low water pressure
and/or temperatures can reduce the water production rate.
Add air pressure to the storage tank, the pressure should be 5 to 7 psi
when the tank is empty.
This system requires min. 40 psi incoming water
pressure. A booster pump maybe needed in low
water pressure area.
Check tubing straighten or repair as necessary.
Replace pre-filters.
Replace the membrane.
Replace the post carbon filter
Replace the membrane
Drain storage tank and refill it overnight.
Replace the flow restrictor
Tighten fittings as necessary
Contact local dealer
Realign drain saddle
