Product Overview
The FPHMR42A3A outdoor five-zone condenser features Friedrich's Precision Inverter Technology, offering a variable speed compressor to keep up with your comfort control needs while still being energy efficient. A standard air conditioner turn off when the set temperature is achieved. An inverter system uses variable capacity to reach and maintain the set comfort level in your space. To help alleviate some of the decisions, we have put together a kit for you which includes 3 indoor wall units and the outdoor compressor.
As a five-zone unit, the FPHMR42A3A gives you the option of adding zone comfort control to your home or office in three, four or five separate spaces. The outdoor unit features Low Ambient Operation making it a great year round option for heating and cooling for most of the US. It will operate in the Cooling Mode when outdoor temperatures are as low as 14°F up to 115°F. The range in which this unit will heat is equally as wide and it will heat when temperatures are as low as -13°F up to 75°F!
Friedrich multi-zone compressors include a built-in troubleshooting control board, standard. This control board gives you the ability to check several parameters on all units from the pump to each connected indoor unit. It is a valuable feature that is typically not included with other brands of mini split compressors. While you will find other manufacturers do offer a trouble shooting control board, it is typically an add-on option. Additional standard features of the Friedrich outdoor unit include:
- Variable Capacity Advantages - Inverter Technology allows each system to adjust capacity and cooling output to provide only the amount of cooling needed at a given time
- Easy installation - Your system will be up and running in just a few short hours in most cases.
- DiamonBlue Advanced Corrosion Protection - Protects the outdoor coil against deterioration and extends the life of the unit especially in harsh coastal environments
- Low installed cost - Ductless systems have a clear advantage over central air conditioning when ducts are not already present
- Lower utility bills - Unlike central air conditioners that cool all the areas the same, ductless systems cool only those rooms you tell it to. No more wasted dollars on cooling unused rooms
- Ultra quiet operation - Ductless systems are in sharp contrast to other types of air conditioners where the rush of air from ducted vents can be annoying, or where compressor noise of window units can be objectionable
- Permanent installation - Unlike traditional window air conditioners, ductless split systems leave window views unobstructed. And, because it is a permanent installation, there is nothing to remove or store over the winter.

Line Sets

Mini Split Line Sets - Line sets are a requirement when installing a mini split system. They are the connection between the outdoor unit and the indoor units of your system. Every indoor unit needs to be connected directly to the outdoor unit with its own line set. Most Mini Split Line Sets come with flared connectors attached and are ready to install. Our line sets are offered with and without control wire and are available in various connection sizes and lengths to meet your installation needs. The line set shown in the photo includes the control wire. With the four indoor wall units included, all you need to add are line sets for each unit. Each 9,000 BTU unit (3) requires 1/4" x 3/8", and the 24,000 BTU unit requires 3/8" x 5/8". Some line sets have white insulation while others have black insulation. This is manufacturer dependent - there is no choice.
This unit must be installed by a qualified licensed HVAC technician.
