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.

RESIDENTIAL HYBRID ELECTRIC HEAT PUMP WATER HEATER, HPE10260H045DV, HPE10280H045DV specifications

The American Water Heater HPE10280H045DV and HPE10260H045DV are pioneering residential hybrid electric heat pump water heaters designed to deliver energy-efficient performance while meeting the hot water demands of modern households. These innovative units fuse traditional electric heating with advanced heat pump technology, allowing for significant reductions in energy consumption compared to conventional electric water heaters.

This technology not only reduces energy bills but also decreases the overall carbon footprint of the home.

The HPE10280H045DV and HPE10260H045DV boast a sleek, compact design that allows for flexible installation options, making them suitable for various locations within a home. Their user-friendly digital interface provides homeowners with intuitive controls to manage temperature settings and monitor performance. These models are equipped with smart technology that includes an intuitive display for adjusting modes and settings. They feature selectable operating modes, including electric, heat pump, and hybrid, allowing users to choose the most efficient heating method based on current needs.

In terms of capacity, the HPE10280H045DV offers a substantial 80-gallon tank, while the HPE10260H045DV provides a 60-gallon capacity, ensuring that households of different sizes can enjoy ample hot water for showers, laundry, and dishwashing simultaneously. Both models are designed with durability in mind, featuring robust components and corrosion-resistant tanks that promise longevity and maintenance-free operations.

Another significant aspect of these hybrid water heaters is their whisper-quiet operation, which makes them ideal for installation in living spaces or areas close to bedrooms. The noise level is minimized by the efficient insulation and placement of the compressor, ensuring that the serenity of the home is maintained.

In summary, the American Water Heater HPE10280H045DV and HPE10260H045DV represent a leap forward in the water heating industry, combining innovative heat pump technology with user-friendly features, energy efficiency, and ample capacity, making them an excellent choice for environmentally conscious homeowners looking for reliable hot water solutions.
