Destrat Pump
MB0001
To aid in thermal disinfection of the tank periodically, and to mix the contents
when operating on the backup element.
The bottom half of the tank is held at temperatures between 20°C and 40°C for
much of the operation of the system. The destrat pump is used to heat the entire
tank twice per week. It is also used when the standby immersion heater is
operating to create a mixing effect in the tank to overcome inaccuracies of flange
mounted stats.

KA1 and CB5. If 230V but pump does not run, check pump and replace if necessary. Once pump is confirmed
to operate, test Timeclock.
