INSTALLATION & OPERATION
INSTALLATION
NOTICE: Replace and tighten air valve cap if it is re moved for any
reason. Failure to replace air cap may allow loss of air pressure
and eventually lead to tank waterlogging and air cell failure.
Pre-charged storage tanks can be connected together to
increase the supply of usable water (drawdown). Two tanks of the
same size will double the supply and three tanks will triple the
supply. See Figures 1A and 1B for typical installations of this kind.
OPERATING CYCLE
1. Tank nearly empty – air expands filling area inside air cell
(Figure 2A).
2. Water begins to enter tank – air is compressed in air cell as
tank fills with water (Figure 2B).
3. Pump-up cycle completed – air pressure has reached the
cut off setting of pressure switch (Figure 2C).
4. Water being drawn from tank – compressed air in air cell
forces water out of tank (Figure 2D).
5. Tank now empty – new cycle ready to begin (Figure 2A).
NOTICE: Drawdown will be affected by operating temperature
of the system, accuracy of the pressure switch and gauge, the
actual precharge pressure, and the rate of fill.
