HEATING ELEMENT REPLACEMENT
WARNING
Heating element removal and replacement involves the
disconnection of electrical wiring. The following proce-
dures must only be performed by a qualified service
technician.
The Watter$aver Heat Pump Water Heater is factory
equipped with a 4500 watt heating element that requires a
30 amp circuit breaker. For installations that don't have an
existing 30 amp circuit for the water heater, ECR International
offers a 3500 watt element kit* that will allow the use of a
20 amp circuit breaker. Voltage/wattage rating information
can be found on the flange or terminal block of the element
or on the unit rating plate.
* For more information on the 3500 watt heating element kit, contact the
factory at the phone number provided with this installation manual.
1. Shut off electric power to the water heater.
2. Drain the water heater as directed under “Draining
and Flushing.”
3. Remove the access cover and fold the insulation
outward and away from the heater element(s). Remove
the plastic thermostat cover from the thermostat,
making sure to disengage the attachment point from
the thermostat.
4. Disconnect the electric wires from the heating
element (Figure 8) and remove the screw-in elements
by turning the element counterclockwise with a 1½”
socket wrench. Remove the existing gasket.

5. Clean the area where the gasket fits to the tank. If
you are replacing the bottom element, remove the
accumulated sediment on the bottom of the tank.
6. Make sure the replacement element has the correct
voltage and wattage rating. Position the new gasket
on the element and insert it into the water heater tank
(Figure 9). Tighten the element by turning it clockwise
until secure.
7. Close the drain valve. Open all hot water faucets and
allow the tank to fill completely with water. To purge
the lines of any excess air and sediment, keep the hot
water faucet open for 3 minutes after constant flow of
water is obtained.
8. Close the faucet and check all connections for
leaks. Check for leaks around the element(s).
9. Connect the electric wires to the heater element.
Make sure the wires are secure and the attachment
points are engaged on the thermostat.
10. Replace the plastic thermostat cover, insulation,
and the access cover(s).
11. Make certain the tank is filled with water. Applying
electric current to heater elements not submerged in
water will destroy them.
12. Restore the electric power supply to the water
heater.
