You can change the operating voltage of your heater by replacing the element or by switching to the alternate
wiring scheme for a dual-use element. Perform the applicable procedure to convert your heater to a different
voltage.
8.1
New Elements with Same Number of Wires
1.
For elements that have the same 2, 3, or 4-wire connection to the element, follow directions for
changing the element in Section 7.0.
2.
Test the unit.
3.
Take a ballpoint pen, cross out the old voltage and put an "x" in the new voltage to update the ETL
label. If the voltage has not changed the label does not need to be updated.
8.2
New Elements with Different Numbers of Wires
For elements with different numbers of wire connectors to the element, remove the electrical box cover with the
fuses.
1.
Refer to Section 7.0, "Changing the Element on Your Heater" to remove the element from the heater.
2.
Unscrew the wire nut and unplug the fuse(s).
3.
Remove or add and connect high temperature wires as needed and reseal the passage way with
silicone.
4.
Obtain and install a different fuse plate as needed.
5.
Test the unit.
6.
Take a ballpoint pen, cross out the old voltage and put an "x" in the new voltage to update the ETL label.
If the voltage has not changed the label does not need to be updated.
8.3
Dual-Use Elements
1.
Refer to Figure 3 or Appendix B to determine if you have a dual-use element and how to reconnect it at
a different voltage.
2.
Reconnect the service to the heater leads, following the appropriate schematic.
3.
Test the unit.
4.
Take a ballpoint pen, cross out the old voltage and put an "x" in the new voltage to update the ETL label.
If the voltage has not changed the label does not need to be updated.
CAUTION
New or replacement element lead wires must be of the very high temperature variety,
capable of handling 1000°F, and with stainless steel terminals.
These are available from Schaefer or your Schaefer HotZone™ dealer.
