Installation (continued)
Pump Protection (continued)
® In the above example
this would mean zones
5 through to 6 would
become active and would
cause the pump to operate
against a closed head
Á This could possibly
cause permanent pump,
pipe and pressure
vessel damage
® It is mandatory if the system
test routine is going to
be used, that all unused,
spare zones, should be
linked together and then
looped to the last working
zone with a valve on it
® Using this example,
the connector block
should be wired as per
the diagram below
Pump Installation
® It is recommended to always use a relay between the controller
and the pump starter for single phase pump installation
