lights. A green light shall indicate the valve is fully open and an amber
light shall indicate the valve is fully closed. Both lights on shall
indicate when the valve is partially open. [Provide torque limit controls
to protect the valve during opening and closing for electrically operated
valves.] Actuator electric motor shall be totally enclosed, [_____] volts,
[_____] phase, 60 Hz as specified under paragraph entitled "Motors and
Drives" in this section. Provide NEMA 4 control enclosures.

Water Softening System
**************************************************************************
NOTE: One hundred percent makeup shall be assumed
in calculating the sustained softening rate.
**************************************************************************
Ion exchange resin type conforming to WQA S-100 except as modified below.
[Manual] [Push button automatic] [Fully automatic] in operation with
operating controls housed in a NEMA 12 enclosure having a total capacity
between regenerations of not less than [_____] liters gallons of water of
[_____] grains hardness when operated at a sustained softening rate of
[_____] L/s gpm. The maximum effluent water temperature shall be [_____]
degrees C F.

Raw Water Analysis
**************************************************************************
NOTE: Regarding the text below: Analysis of the
water available for makeup shall govern the softener
system selected. A competent water treating
consultant shall be obtained to formulate specific
system recommendations if the makeup water analysis
indicates any of the following:
1. Iron in excess of 0.1 ppm as Fe.
2. Mg Alkalinity in excess of 50 ppm as CaCO3.
3. Silica in excess of 6 ppm as SiO2.
**************************************************************************
The source of the raw water is [_____]. It is available at pressures of
[_____] to [_____] kPa (gage) psig. The analysis of the water available
for makeup is approximately as follows:
