Water starvation protection
In systems where it is absolutely not possible
to increase the usable cold water storage
capacity to meet the increased demand of a
pumped system; a water starvation protection
unit (WSP) may be considered.
The WSP is a Salamander level switch which
must be positioned 102mm higher than the
highest outlet from the cold water storage
tank. When the water level drops too far the
WSP will switch off the pump until the cold
water storage level is recovered.
