1. Where do I locate the thermostat?
    In the growing room.
  2. How do I connect (wire up) the thermostat?
    There is a specific wiring diagram found here.


  1. What size unit do I need?
    See chart to the right.
  2. How much humidity will my unit remove?
    See chart to the right.
  3. Can I connect the unit to a permanent drain?
    Yes, see the instruction manual that came with your unit. Copies can be found at on the "Documents" tab of the product detail page.
  4. Can I mount the unit on the wall?
    Yes, it is possible. Be sure that the unit is level to ensure proper drainage.
  5. How does a dehumidifier work?
    Moist air is drawn into the dehumidifier and then crosses a refrigerant cooled coil, the moisture in the air condenses on the coils within the machine. The moisture drips off the coil and into the drain bucket. The air that was drawn into the dehumidifier enters back into the room dryer and warmer then when it entered. This process continues until the humidity level you select has been reached or the drain bucket fills up shutting off the machine. Have you ever noticed when you have a cold drink on a hot day, water collecting on the outside of the glass? This is another example of how a dehumidifier works.
  6. Do these units have auto restart?
    Yes, in the event of a power interruption the unit will automatically restart and retain the previous settings.
  7. I see frost on the coil, is this normal?
    Yes, when the ambient air temperature is below 59°F frost can develop on the coil. These units have an automatic defrost system that will melt the frost. The condensation than drains into the reservoir and the process repeats itself.
  8. What humidity settings are available?
    The settings are in 10% increments. 40/50/60/70/80. When the 40% setting is used the unit will run continuously.
  9. What voltage are these units?
    Both the 60 pint and 100 pint run on 120 volts.

Ductless Mini-Splits

  1. How do I connect (wire up) the optional thermostat?
    Installation is easy. Please refer to both the installation diagram and the wiring diagram on the Ideal Air website at
  2. Can I relocate the system after the original installation?
    Yes. Care should be taken NOT to kink refrigerant lines or otherwise damage the components. As a precaution, we recommend closing the refrigerant valves on the outdoor units using an Allen Wrench.
  3. What do I do with the extra line set?
    If there is extra refrigerant line set, simply coil it in a convenient manner. As a precaution, take care to prevent it from damage by lawn care activities, or from being covered in water or by soil.
  4. Do you offer a longer line set, or is it possible to lengthen the line set?
    No, we do not offer a line set extension. Similarly, we do not support cutting the line and splicing in an extra length-this will void the warranty.
  5. Do you recommend that I use the "Auto Changeover" feature?
    We do not recommend using the Auto Change over. While the feature functions, we have found from experience that auto-changeover does not respond quickly enough to satisfy customers.
  6. Why is there ice build-up on the unit, line sets, etc?
    There are several causes for ice buildup, and these are typically a result of a lack of filter maintenance, loss of refrigerant, or normal operation. Please refer to the owners manual that came with the unit. Additional copies can be found on the Ideal Air website at
  7. What is the warranty?
    VGenerally we offer a 1 year warranty, however the details differ from product to product. Please refer to the warranty section of the Ideal Air website at
  8. Can I order a replacement remote control?
    Yes, please contact an authorized Ideal Air retailer to place an order.
  9. Why does the indoor fan run continuously?
    This is NORMAL and all ductless mini-splits operate in this way. The fan moves air through the indoor unit in order to sense the room temperature. There is a room temperature sensor located in the indoor unit.
  10. How loud is the outdoor unit?
    The outdoor unit is designed to be very quiet. The nose rating differs from each model. Please refer to the specifications on the Ideal Air website at
  11. Can I install it myself?
    Yes. All of the Ideal Air ductless mini split air conditioners are designed to be installed by the do it yourself crowd.
  12. Do I need a service technician to charge these units with refrigerant and start them?
    No, the refrigerant line set is pre vacuumed at the factory, (no need for a vacuum pump or refrigerant gauges) the correct amount of refrigerant for the entire system is in the outdoor unit. Mount the indoor unit, drill a 3" hole in the wall, pass the line set and condensate drain line thru this hole to the outdoor condensing unit, hook up the quick connect refrigerant fittings, open the service valves using the included allen wrench, hook up the control wires and power. Start the unit. Always spray a soapy solution on the quick connect fittings and check for leaks. (Bubbles) if you see bubbles forming you will need to tighten the quick connect fitting until they stop.
  13. Will these units affect any CO2 I introduce to my room?
    No. The air conditioner simply circulates and cools the air already in the room.
  14. Can these units be serviced by any air conditioning technician?
    Yes, these units have service ports and use R-410 A refrigerant.
  15. Will rain or snow damage the outdoor condensing unit?
    No, these units are built to withstand years of outdoor service.
  16. Can I attach the outdoor unit to a wall or do they only sit on the ground?
    Yes, it's your choice, all ideal air mini split air conditioners come with an exterior wall mount bracket, or you can place them on a flat level surface.
  17. Can I plug the air conditioner into any outlet that is available?
    No, each unit must have its own dedicated power circuit. A surge protector is also recommended.


  1. Why is there an excess amount of water on the surface surrounding my unit?
    This can happen as a part of normal operations. The Humidifier operates by "slinging" water through the internal parts and blowing air. If you are concerned about a leak, fill the unit with water and TURN OFF the power. It will become immediately clear if the reservoir leaks.
