SEQUENCE OF OPERATION

E32 series medium duty, field convertible commercial electric water heaters are designed to operate using single phase or three phase service connections. One size fits all Internal fusing is factory installed for all units. When field conversions are required, no fuse change is necessary. Three surface mounted thermostats operating independently are used to control a corresponding heating element.

Sequence of Operation.

across terminals L1 and L2 of terminal

 

block. Or Three phase line voltage is

 

applied to terminals L1 through L3 of

 

terminal block. Line voltage continues

 

through terminal block and fuse blocks

 

and connects to thermostats at

 

terminals L1 & L3.

Terminal Block

 

 

 

2ECO (high limit) in thermostat is closed, so there is line voltage present at terminal L4 of thermostats and to one side of each element.

3Water in tank is cold, so all thermostats are closed at terminal T2 (calling For heat). This completes the circuit and allows current to flow through heating element.

 

As each thermostat is satisfied,
