7.Clean the area where the gasket(s) fits to the tank and internal threads. If you are replacing the bottom element, remove any accumulated sediment on the bottom of the tank.
8.Make sure the replacement element(s) has the correct voltage and wattage rating by matching it to the rating plate on the water heater. Position the new gasket(s)
on the element and insert it into the water heater tank (Figure 13).
NOTE: Apply a light coat of hand dishwashing soap and water to the gasket. Tighten the element by turning it clockwise until secure.
9.Close the drain valve and open the nearest hot water faucet. Then open the cold water shut off valve 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 a constant flow of water is obtained.

15.Reconnect electrical power to the water heater at the circuit breaker/fuse box.
16.Press the power button to turn the water heater on. Set the desired water temperature and operating mode. NOTE: The water heater will conduct a system diagnostic (approximately 8 minutes) prior to operation.
Routine Preventive Maintenance
At least monthly, a visual inspection should be made of the following:
•Air Filter (Remove and inspect, clean if needed, and reinstall).
•Condensate drain pan and condensate lines.
•The lower metal drain pan for standing water which may indicate a clogged condensate drain pan, condensate lines, or plumbing leak.
•Leaking or damaged water piping.
•Presence of corrosive materials in the installation area.
•Presence of combustible materials near the water heater.
•After servicing this water heater, check to make sure it is working properly. (See “Operating Your Water Heater” section of this manual.)
IMPORTANT: If you lack the necessary skills required to properly perform this visual inspection, you should not proceed, but get help from a qualified person.
Cleaning the Heat Pump
Air Filter Cleaning/Replacement
IMPORTANT: Before attempting to clean or replace the air filter press the power button to place the water heater in Standby Mode and
1.Locate the screw securing the filter panel to the heat pump shroud and loosening it.
2.Remove (slide) the filter from the unit.
3.If you are replacing the filter skip to step 4. To clean the filter use a vacuum with a hose attachment to remove any dust or debris.
4.Place the new or cleaned filter into the water heater and secure the filter to the shroud with the screw loosened earlier.
NOTE: The guides/slots when inserting the filter into the water heater.
5.Restore power to the water heater and press the power button to turn the water heater on. NOTE: the water heater will conduct a system diagnostic prior to operation.
Inspection/Cleaning of the Condensate Drain Pan & Condensate Drain Lines
IMPORTANT: Before attempting to clean or replace the condensate drain pan or lines press the power button to place the water heater in Standby Mode and
1.Remove the access panel (fan side) by loosening the screws securing it to the unit.
2.Check the condensate drain pan and drain lines for any dirt or debris that might interfere with proper drainage. Wipe out any dirt or debris with a damp cloth.
3.Once the condensate drain pan and lines have been inspected/cleaned, secure the access panel to the water heater.
4.Restore power to the water heater and press the power button to turn the water heater on.
NOTE: The water heater will conduct a system diagnostic prior to operation.
