Thermostat (Procedure 3); Element (Procedure 4) - Rheem Everhot 2A1050M7 Service Instructions Manual

Thermostat (Procedure 3)

Personal Protective Equipment should be worn when conducting step 2 of
this procedure to reduce the risk of electric shock.
1. Isolate the power supply to the water heater and remove access cover.
2. Confirm with multi-meter between Active and Neutral at the terminal block that
voltage is not present.
3. Remove the thermostat protective cover and disconnect the wiring from the thermostat
(Note wiring positions).
4. Slide thermostat vertically out of clamp. Note the current temperature selected.
5. Remove any impurities from the cylinder surface.
6. Slide replacement thermostat into place behind clamp, set temperature to that noted in
step 4 and connect wiring to appropriate points (refer to "Wiring Diagrams" section on
page 8). Note: Ensure thermostat face is in good contact with cylinder surface.
7. Check water heater internal wiring insulation for cracking.
8. Conduct an electrical insulation test (refer to "Electrical Insulation Testing" on page 24).
9. Refit the thermostat protective cover and the lower access cover.
10. Restore the power supply to the water heater.

Element (Procedure 4)

Elevated temperatures may be present during element removal process.
Personal Protective Equipment should be worn to prevent the risk of
scalding.
When a fault or leak is traced to the element, the water heater should be drained to
prevent damage to flooring or floor coverings by accidental flooding.
1. Drain the water heater (refer to procedure 1).
2. Remove the thermostat protective cover and disconnect the element wiring from the
thermostat.
3. When the water heater is drained, undo the four element screws, removing thermostat
clamp first.
4. Withdraw the element. Care must be taken to ensure the loop of the element does not
catch in the cylinder opening and open out inside the cylinder.
NOTE: Do not cut off the element and leave a portion inside the cylinder.
5. Clean around cylinder fitting, fit a new gasket to the new element and slide the element
into the cylinder (reverse to step 3) taking care that it is in the correct orientation.
Refer to element flange for orientation directions. Note: Never reuse old element
gaskets.
