Size piping between the CS-1 and the system to minimize pressure drop.
Too small of a line size restricts pump flow, lowering capacity when filling
the system. Lower capacity while filling the system requires longer fill
times. The sprinkler system must contain air vent/bleed valves at all local
high points. These are used to let air out of the system while filling with
antifreeze. Consult the system instructions for specifics.
Individual check valves and isolation valves are required for each system.
This allows system maintenance without disturbing other systems the CS-
1 is connected to. Piping and/or hoses from the antifreeze supply
containers to the unit should be sloped downhill slightly to provide positive
head on the pump suction connection. These lines should be as large as
possible and as short as possible to provide unrestricted flow to the 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 & fire codes.
7.5 Electrical
Connections
SERIOUS PERSONAL INJURY AND DAMAGE TO THE CS-1 COULD
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 MFR 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.
