The Alpine AHEU1P Uncased Upflow/Downflow Indoor Coils are made by Ducane for split system air conditioners and heat pumps.

This unit comes equipped with an orifice (flowrater) for the listed tonnage. If you wish to pair the coil with a condenser or heat pump of a different tonnage, an orifice in that tonnage will need to be used (unless a TXV is required instead). See this step-by-step guide to learn how to easily change the orifice.  Alternatively, instead of an orifice a thermostatic expansion valve (TXV) may be used or required for some equipment.

Check out some additional installation Tips for Selecting Matched Components and Line Sets to help with your installation project.

Standard Features

  • Suitable for use with R-410A and R-22 refrigerants
  • Microban® antimicrobial additive in the drain pan to resist mold and mildew growth
  • One of the lowest water retention drain pans in the industry to minimize mold and mildew growth
  • Drain pans are compatible with UV lights
  • Two dual drain connections on front of coil for installation flexibility of drain lines around furnace vent and utility connections
  • Orifice assembly designed for easy changing of orifice sizes and fast TXV connections

Note:   Before you purchase an evaporator coil, make sure the width and height of the coil does not exceed the available area in your ductwork where the coil will be installed. If it does, select a coil with smaller dimensions. (If the coil depth exceeds the available space, this is usually okay since the ductwork can be modified to make it fit, as shown in our installation video.)

Configuration

Configuration is the direction the conditioned air will pass through the unit.

Upflow units will have the air come in from the bottom and blow out the top.

Horizontal units will have the air go through the unit left to right, or right to left.

Downflow units will have the air come in from the top of the unit, and blow out the bottom.

Refrigerant

Inside air conditioning systems are liquid/gas refrigerant. There are two types of this refrigerant available for use, R-22 (more commonly known as Freon), and a newer alternative R-410A.

An air conditioning system does not consume refrigerant, but reuses it. As long as there are no leaks in the refrigerant circuit, there is no need to ever add more refrigerant to an air conditioning system.

Although R-22 is an effective refrigerant, if it is released into the atmosphere it can contribute to the depletion of the Earth’s ozone layer. The EPA has mandated the phasing out the use of R-22. It is being replaced by R-410A.

As of 2010, manufacturers are required to make all new air conditioners with R-410A. However, R-22 is still available for sale in existing pre-2010-manufactured equipment, and for use in servicing existing R-22 equipment. By 2020, R-22 will no longer be manufactured, but will still be recycled and available for sale.
