sequence.
Install cartridges in proper sequence as
indicated in system components.
Cartridges are upside-down.
Install carbon block filter right-side-up as
indicated on the filter.
No pressure in storage tank.
Check pressure with pressure gauge. Refill or
reduce pressure to max 8 psi. Note: Tank

Change in feedwater
temperature.
The reverse osmosis membrane used in your
unit is rated at 77ºF and 60psi. Water
production will decrease approximately 1.5%
for each degree that your incoming water is
below 77ºF. It may be necessary to change to
a higher flow membrane (and flow restrictor).
Storage tank pressure is too
low.
Check pressure with gauge and refill to
maximum 8 psi. Note: Tank must be empty of
water when checking the air pressure.
