Subject: change of part number for recirculators

During these years we have used recirculators in installations as hot water return in capacities ranging from 1/6 to 2 hp, with single-phase voltage 115 volts and two-phase 230 volts, our service department has told us that when they are connected to 115 volts the motor gets too hot due to the load, when they change to 230 volts (two-phase) it improves, but not enough to move the recirculation water . To improve the charging of our recirculators we have decided to change them to 230/460 volts, only applicable for some models, Clayton part numbers M007439 (1/4 hp) and M007441 (1/6), will continue to be supplied in 115/230 volts, Due to their capacity, they are not supplied in different voltages, the aquastat does not change its voltage, it will continue at 115 volts.

Our installation area will have to modify its electrical diagrams and elements that affect its installation in accordance with the voltage indicated in this bulletin and in the sales order .
