This unit should go in a shaded location outside the house where it can have at least 4 inches of clearance behind it and 20 inches of clearance above it and in front of it. The 119-pound unit can be mounted on brackets fastened to the wall, as shown, or bolted to concrete blocks resting on the ground. Locate the Air Handler It mounts on an exterior wall no more than 33 feet from the outdoor unit, at least 2⅛ inches below the ceiling and 3 feet from a TV. First, the mounting plate is screwed to the studs, as shown. At the plate's lower-right corner, the installer drills through the wall with a 3-inch hole saw. Outside, a connecting hole is drilled ¼ inch below the one inside. Mount the Air Handler

With the cover off, the control wire, refrigerant lines, and condensate drain hose are attached to the unit and taped together, and a protective sleeve is fitted into the hole in the wall. water not draining from ac unitThe unit is hoisted up without its fins being touched, and the taped parts are fed through the sleeve, as shown. air conditioning unit wallThe unit then mounts to the plate.ac unit drain pipe clogged Set Up the Condenser The outdoor unit is connected to the control wire from the indoor unit and to a jacketed power cable leading to the breaker panel. Then the ends of the refrigerant lines are fastened to the condenser with flare nuts, as shown. Flare nuts are also used to join these lines to the ones on the indoor unit.

A plastic channel screwed to the siding hides the lines, condensate hose, and control wire. After the hose is checked to make sure it drains freely, the end of the hole sleeve is sealed with silicone to prevent water infiltration. Then the channel is capped, as shown. A gauge manifold and a vacuum pump are hooked up to the refrigerant lines to detect leaks and dry the lines as refrigerant is pumped into them. The last step is to put the cover on the air handler, as shown. The system is then ready to heat and cool. The Department of Energy (DOE) has regulated the energy efficiency level of packaged terminal air conditioners and heat pumps since 1994. Packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs) are through-the-wall space conditioning units commonly used in lodging, townhouse office complexes, and extended care facilities. The amended standard adopts the efficiency levels in ASHRAE 90.1-2013 for standard-size packaged terminal air conditioners.

DOE has published a final rule and correction regarding energy conservation standards for packaged terminal air conditioners and packaged terminal heat pumps 80 FR 56894 (September 21, 2015). For more information, please see the rulemaking page. DOE has published a final rule regarding test procedures for  packaged terminal air conditioners and packaged terminal heat pumps 80 FR 37136 (June 30, 2015). For more information, please see the rulemaking page. DOE published notice of proposed rulemaking and public meeting regarding energy conservation standards for packaged terminal air conditioners and packaged terminal heat pumps. 79 FR 55538 (September 16, 2014).  A public meeting is scheduled for Wednesday, October 29, 2014, from 9 a.m. to 4 p.m., in Washington, DC. For more information, see the rulemaking page.DOE published a notice of public meeting and availability of the framework document regarding energy conservation standards for packaged terminal air conditioners and packaged terminal heat pumps.

78 FR 12252 (February 22, 2013). For more information, see the rulemaking page. The following content summarizes the energy conservation standards for packaged terminal air conditioners and heat pumps. Standard size PTAC or PTHP refers to equipment with wall sleeve dimensions having an external wall opening greater than or equal to 16 inches high or greater than or equal to 42 inches wide, and a cross-sectional area greater than or equal to 670 square inches. Non-standard size refers to PTAC or PTHP equipment with existing wall sleeve dimensions having an external wall opening of less than 16 inches high or less than 42 inches wide, and a cross-sectional area less than 670 square inches. Standard size packaged terminal air conditioners or packaged terminal heat pumps manufactured on or after September 30, 2012, and distributed in commerce, as defined by 42 U.S.C. 6291 (16), must meet the energy conservation standards specified in the Code of Federal Regulations 10 CFR 431.97(c).

The standards apply to non-standard sized packaged terminal air conditioners and heat pumps manufactured on or after September 30, 2010.Energy Conservation Standards for Commercial Package Air Conditioners (British thermal units per hour [Btu/h]) <7,000 EER = 11.7 7,000 – 15,000 EER = 13.8 – (0.300 × Cap* ) >15,000 <7,000 EER = 9.4 7,000 – 15,000 EER = 10.9 – (0.213 × Cap* ) >15,000 <7,000 EER = 11.9 COP = 3.3 7,000 – 15,000 EER = 14.0 – (0.300 × Cap* )COP = 3.7 – (0.052 x Cap* ) >15,000 <7,000 EER = 9.3 COP = 2.7 7,000 – 15,000 EER = 10.8 – (0.213 × Cap* ) COP = 2.9 – (0.026 × Cap*) >15,000 * "Cap"means cooling capacity in thousand Btu/h at 95 °F outdoor dry-bulb temperature. Final Rule: Standards, Federal Register, 73 FR 58772 (Oct. 7, 2008) To determine compliance with DOE standards, manufacturers must follow the test procedures specified at 10 CFR 431.96 for packaged terminal air conditioners and packaged terminal heat pumps.
