pump while filling. A separate shut-off valve in the supply line is required.
Unit piping is copper, brass and bronze. An aluminum manifold is included for mounting
multiple system solenoids. Use dielectric unions to isolate copper piping from iron piping, if
used, to reduce the possibility of electrolytic action on pipes and other components.
All pipes should be de-burred and threaded to a proper depth and length before installation.
Threads should be inspected for cleanliness and depth of cut. Good quality pipe compound
should be used to ensure a good, leak-tight fit of piping components.
NOTE: Pipe must be supported separately from the CS-1. At no time should the CS-1
support the weight or load of the pipe. Acceptable pipe mounting devices would be
unistrut supports anchored to walls, hangers suspended from ceilings, or pedestals
mounted from the floor. Be sure all pipe installation conforms to all building and fire
codes.
4. Electrical Connections
SERIOUS PERSONAL INJURY AND DAMAGE TO THE CS-1 WILL OCCUR IF IT IS
CONNECTED TO A POWER SOURCE OTHER THAN THE VOLTAGE LISTED ON THE
DATA TAG. THE MANUFACTURER IS NOT LIABLE FOR DAMAGE DUE TO IMPROPER
WIRING, PROTECTION, OR ELECTRICAL SERVICE INSTALLATION.
When installing electrical service to this machine, comply with the National Electric Code
as well as state and local building codes.
Failure to install the proper electrical protection can result in personal injury, fire, equipment
damage or death. The manufacturer is not responsible for damage or injury caused by lack
of or improperly installed electrical protection.
Electrical connection to the unit is made in the control enclosure. Connect appropriate
supply power to the terminals provided. The supply wire must be of adequate size and no
other equipment should be connected to the same circuit. An arrow on the pump indicates
the correct direction of rotation. If the pump rotates in the opposite direction, reverse the
rotation of the motor. Interchanging any two incoming 3-phase supply wires reverses rota-
tion of 3-phase motors.
WARNING: Operating the pump in the wrong direction may damage the pump. Verify
pump rotation is correct before placing the unit in service. Make sure there is liquid
on the suction side of the pump before checking rotation.
Connect system inputs to the proper terminals in the CS-1 control enclosure. Each system
pressure switch and alarm flow switch are connected as shown on the electrical sche-
matic.
NOTE: All system inputs must be connected before operating the unit. System
valves will not respond unless the system pressure switch and flow alarm switch
are connected correctly.
5. Start-Up
The following points must be verified before putting the unit into service. Correct any dis-
crepancies before operating the unit:
The unit is bolted to a firm level surface.
Area temperature will always remain between 40 °F and 100 °F (4.4 °C to 37.8 °C).
