Ask a Question
  • How many amps on this unit? What gauge wire to run unit?

    This would take a 20A breaker with 12 AWG wire.

  • What are the starting and running watts?

    This is an inverter-type system with slow-start technology so starting watts are close to 0. Rated capacity input wattage is 1,070W. For more info see here:

  • How many square feet is this unit work for?

    For standard applications, we recommend this particular unit for spaces between 200 and 450 square feet.

  • Does the unit use the remote as a thermostat?

    Yes, that is correct.

  • Is there a listing as to what size room these units will provide for in square footage?

    To figure out BTU needed per room we recommend our HVAC calculator.

    Also check the tech brochure which has suggested square footages for each model.

  • need 25 ft electrict line set

    The Diamante series comes pre-packed with a 16 ft lineset which cannot be modified during purchase. If you need longer, it would require purchasing either the WYS series, or a longer lineset here.

  • What size circuit breaker does this require? Also, if I am using a fused disconnect what size fuse should I use?

    This would take a 20A breaker. You can use a 30A disconnect alongside that.

  • Is this system fully charged so I don’t need special equipment to do the install

    The way it works is that the outdoor condensing unit is pre-charged with R410a to support line lengths up to 25 ft long. You will need to remove the air from the lines before releasing the refrigerant from the outdoor unit, using a vacuum pump or the flushing kit that we sell.

  • Does the 115v unit require 12/2 or 12/3 wiring?

    It would require 1 hot line, 1 neutral line, and one ground.

  • I can't seem to find the power draw of these units online, what is the amp draw for these units? Thanks.

    Please see the full electrical and technical specs for this series here:

  • does this series have the "Vacation mode" where you can set a very low heating set point ( 45 deg) when unoccupied?

    Yes it does, this is done by pressing the AH button on the remote.

  • Is this an inverter system

    Yes, this is a heat pump and variable-speed inverter.
