Compu-aire MINI-TEMP PLUS Installation, Operation & Maintenance Instructions Manual page 23

If the water reaches top of cylinder before 110% F.L.A. the fill
valve shuts off via the sensor and fill-boil-fill-boil cycle
continues, cycling off the red full cylinder light until the
concentration becomes high enough to reach 100% F.L.A. Then the
following described control process takes over.
WATER SUPPLY AND PLUMBING
1.
The orifice in the fill valve(s) is sized for an extended
water pressure range of 30 to 85 psi.
2. For water pressure between 15 and 30 psi, noti the factory
and the next larger size of fill valve will be supplied.
3. For cases below 15 psi, notify the factory and fill valve with
largely oversized orifice will be supplied.
4. For cases above 85 psi, install a pressure reducing valve in
the water feed line to the unit. Otherwise insufficient
cylinder water will drain when fill and drain mix during the
automatic dilution cycle.
5. With extremely dirty or muddy water sources, e.g. some well
sources, ensure proper filtration by adding and external
filter to the water line entering the unit. (Consult factory
for accessories such as filters).
6. DO NOT soften water with Condair unit because it is much too
conductive.
7. DO NOT use completely demineralized water with the Condair
unit as it is the minerals that allow the electrode principle
to work.
8. DO NOT use a hot water source as it will cause deposits to
eventually block the fill valve orifice.
Water Connection
1. A copper compression olive type coupling for 1/4" soft copper
tubing is provided with unit and requires no soldering for the
water connection to the unit.
