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 “Operational Overview/Initial Start Up” (p.12)

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/Replacing the Air Filter

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 turn-off power to the water heater at the circuit breaker/fuse box.

1.Locate the screw securing the filter panel to the heat pump shroud and remove 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 filter panel and secure the filter to the shroud with the screw loosened earlier. Use the slots for guides when inserting the filter into the water heater and replace the screws.

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.
