Location Requirements, Site location | A.O. Smith PHPT-80 guide

•The water heater must NOT be placed on its side. It should be transported and stored in an upright position.

•Remove exterior packaging and place installation components aside.

•Inspect all parts for damage prior to installation and start-up.

•Completely read all instructions before attempting to assemble and install this product.

•After installation, dispose of/recycle all packaging materials.

Location Requirements

Site location

Select a location near the center of the water piping system. The unit must be installed indoors and in a vertical position on a level surface. The ﬂooring beneath the water heater must be able to support the weight of the water heater when ﬁlled with water (967 lbs. full).

IMPORTANT: The water heater must be located in a space 750 cubic feet or larger, and must have unrestricted airﬂow. As an example, a room that has an 8 foot tall ceiling and is 10 feet long by 9-1/2 feet wide would contain 760 cubic feet.

NOTE: For optimal efﬁciency and serviceability, the

following clearances should be maintained: 3 feet on the air inlet side, 5 feet. on the air outlet side, 6 inches in the back, and 2 feet in the front.

The water heater should be located in an area not subject to freezing temperatures. Water heaters located in unconditioned spaces (i.e., garages, basements, etc.) may require the water piping, condensate piping, and drain piping to be insulated to shelter against freezing. The drain and controls must be easily accessible for operation and service.

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, refrigerants, and many other commercial and household products. In addition, excessive dust and lint may affect the operation of the unit (See “Cleaning the Filter” section).

The ambient air temperature must also be considered when installing this unit. In Efﬁciency Mode the ambient air temperature must be above 45°F and below 109°F. If the ambient air temperature falls outside these upper and lower limits the electrical elements will activate to meet the hot water demand and the heat pump does not operate.

NOTE: Local codes and requirements in your area may require the installation of your water heater be accomplished in a way that the bottom element is elevated from the

ﬂoor at least 18 inches. Ensure that a platform capable of supporting the combined weight of the water heater and water (967-pounds) is used.

IMPORTANT: The water heater should be located in an area where leakage of the tank, connections, condensate lines or condensate will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water, the tank will eventually leak after an extended period of time. Also, any external plumbing leak, including those from improper installation, may cause early failure of the tank due to corrosion if not repaired. If the homeowner is uncomfortable with making the repair a qualified person should be contacted. A suitable metal drain pan should be installed under the water heater as shown below, to help protect the property from damage which may occur from condensate formation or leaks in the piping connections or tank. The pan must limit the water level to a maximum depth of 2-1/2 inches and be two inches wider than the heater and piped to an adequate drain. Locate the water heater near a suitable indoor drain. Outside drains are subject to freezing temperatures which can obstruct the drain line. The piping should be at least 3/4” ID and sloped for proper drainage. Under no circumstance will the manufacturer or seller of this water heater be held liable for any water damage which is caused by your failure to follow these instructions.
