Operating Instruction

2 System Design

The following diagrams show typical single pump and multi-pump systems using the

Technovar control unit. Connection can be made directly to a water supply or water can be

drawn from a break tank or well. In the case of break tanks and wells, level switches, should

be used to shut down the pumps when water is low. In the direct connection, a pressure

switch on the suction side should be used.
