Dual-Pump System Installation

Fig. 15 Dual-pump application

CAUTION!
Before carrying out any work, check that any automatic control
equipment, etc., is disconnected from the power supply and
cannot become live.

NOTE: Some useful hints and examples are given in Chapter 6, page 27,
Single-Pump System Installation.

NOTE: The dual-pump DCM system must not be installed in a pit of
extremely small diameter or width. This will result from time to time in the
DCMs failing to detect the stop/minimum level.
