IMPORTANT: Make sure SM Series system is completely
installed and operative. Check that all connections are air tight.
Snap Ring
1. Make sure that the pump assembly is connected to a power source,
either 120 VAC or 230 VAC according to the pump model used.
2. Depress the read button, located next to the gage(s) and hold until the
gage pointer stops traveling across the scale. See Fig. 6, at right.
3. When pointer stops release the read button to allow pointer to settle.
4. The value observed in the dial of the gage, is the level of the tank.
5. Perform this operation as necessary for each tank to be checked.
