Installation Checklist

Water Heater Location

•Centrally located with the water piping system.

•The ﬂooring beneath the water heater must be able to support the weight of the water heater when ﬁlled with water (see Table 1).

TABLE 1: Weight of water heater, full of water

Capacity	Weight (lbs)
60 Gallon	760
80 Gallon	967

•Located indoors (such as a basement or garage) and in a vertical position. Protected from freezing temperatures.

•Provisions made to protect the area from water damage. Metal drain pan installed and piped to an adequate drain.

•Sufficient room to service the water heater.

•Sufficient air for the heat pump to function. The approximate minimum air requirement is 750 cubic feet of space. For example: this would be a room approximately 10’X9 1/2’ in size with an 8’ ceiling. NOTE: For optimal efﬁciency, the following minimum clearances should be maintained: 3 ft. on the air inlet side, 6 ft. on the air outlet side and 2 ft. front and back.

•Unrestricted airﬂow, the unit cannot be placed into any type of closet or small enclosure.

•The site location must be free from any corrosive elements in the atmosphere such as sulfur, ﬂuorine, and chlorine. These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint and varnish removers, and many other commercial and household products. In addition, excessive dust and lint may affect the operation of the unit and require more frequent cleaning, see “Cleaning/Replacing the Air Filter” section (p.11).

•Ambient air temperature must be between 45°F and 109°F (inclusive) in order for the heat pump to work properly. If the ambient air temperature falls outside these upper and lower limits the electrical elements will activate to meet hot water demand.

Water System Piping

•Temperature and pressure relief valve properly installed with a discharge pipe run to an adequate drain and protected from freezing.

•All piping properly installed and free of leaks.

•Heater completely filled with water, see “Water Piping System” section (p.9).

•Closed system pressure buildup precautions

installed, see “Closed System/Thermal Expansion” section (p.10).

•Mixing valve (when applicable) installed per manufacturer’s instructions see “Water Piping System” (p.9).

Condensate Drain Line Installation

•Must be located with access to an adequate drain or condensate pump.

•Condensate drain lines installed and piped to an adequate drain or condensate pump.

Electrical Connections

•The water heater requires nominal 240 VAC for proper operation.

•Wiring size and connections comply with all applicable codes or in the absence of local or state codes follow NFPA-70, the National Electrical Code-current edition.

•Water heater and electrical supply are properly grounded.

•Wiring enclosed in approved conduit (if required by local codes).

•Dedicated circuit with proper overload fuse or circuit breaker protection installed.

Post Installation Review

•To maintain optimal operation check, remove and clean the air filter see “Cleaning/Replacing the Air Filter” section (p.11).

•Understand the importance of routine inspection/ maintenance of the condensate drain pan and lines, see “Inspection/Cleaning of the Condensate Drain Pan & Condensate Drain Lines” (p.46). This is to help prevent any possible drain line blockage resulting in the condensate drain pan overflowing. IMPORTANT: Water coming from the plastic shroud is an indicator that both condensation drain lines may be blocked. Immediate action is required.

•Understand how to use the User Interface Module to set the various modes and functions, see “Adjusting the User Interface Module/Operating Modes” (p.12-13).

•Understand the various Operating Modes and which mode may be best based on season, ambient temperature, and usage see “Operating Mode Description” (p.12-13). NOTE: It may be necessary to temporaily change modes if, for example, filling a spa or hot tub.

•The Installation Instructions and Use & Care Guide should be kept with the water heater for reference.

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.

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.
