FAQ

There are 2 possible reasons: 1. If you have just switched it on in heat mode (or set it to heat when it was previously in another mode), the mini split needs 2-5 minutes to preheat before the fan starts blowing air at a normal flow. During this time, the fan will stop or blow a minimal amount of air, to avoid recirculating cold air. 2. If the unit has been operating properly in Heat mode and it suddenly stops blowing air, the unit may have gone into defrost mode. In order to melt ice/snow accumulated on the outside unit so that it can operate properly, the unit will go into defrost mode automatically. Since, in essence, during defrost mode the unit switches to Cool, the fan will stop or blow a minimal amount of air, to avoid supplying cold air. The defrost mode will last between 2 and 10 minutes maximum. During this time, depending on your model you may see “df” or “C8” on the display. On some of the newer units, the user can initiate the defrost cycle manually by pressing the ECO button rapidly 10 times within 8 seconds when the unit is in Heat mode.

CL is a reminder to clean the filter (Appears after a certain number of hours of fan operation- 500 on most models) . If the device does not have filter reset button, the way to reset this code is to turn off the power (at breaker) for a couple of minutes.

The code will reset if the you power down the unit (via the breaker) or after about 72 hours on its own.

The MSCT units only have an air intake at the top of the coil. See image below.

Absolutely, this is a heat pump. A reversing valve on the refrigeration circuit allows it to switch from cooling to heating and vice versa. THIS UNIT IS ENERGY STAR COLD CLIMATE CERTIFIED (see attached). If you are looking for a heat pump and its performance in heating is as important or even more important than its performance in cooling, its SEER (or SEER2) rating is not as important as its HSPF2 rating and other heat related ratings. SEER (or SEER2) is the total heat removed from the conditioned space during the annual COOLING season, expressed in Btu, divided by the total electrical energy consumed by the air conditioner or heat pump during the same [cooling] season, expressed in watt-hours. HSPF (or HSPF2) is the total space heating required in region IV [ Iowa, Minnesota, Missouri, North Dakota and South Dakota] during the space HEATING season, expressed in Btu, divided by the total electrical energy consumed by the heat pump system during the same season, expressed in watt-hours. this unit has the following ratings by AHRI: HSPF2(Region IV) 9.0, Rated heat capacity at 47F 9500BTU; rated heating capacity at 17F: 6000BTU; COP at 5f 1.75; Max heating capacity at 19F: 8000 BTU, and at 5F 7000 BTU. This unit is Energy Star CERTIFIED, due to the combination of some of these ratings, and may be eligible for a tax rebate. For more information, contact the seller.

HERE ARE THE ERROR SIGNALS THAT DISPLAY ON YOUR UNIT Understand the error codes that display on the Indoor Unit: E0 - (Common at Start Up) - Lost Communication between Indoor and Outdoor Units (If at initial startup, check for miswiring or broken or disconnected Cable #1, Leftmost of 3, may be labelled differently) E1 - Indoor Temperature Sensor Fault E2 - Indoor Pipe Temperature Sensor Fault E3 - Outdoor Pipe Temperature Sensor Fault E4 - Refrigerant System Leakage or Fault E6 - Malfunction of the Indoor Fan Motor E7 - Outdoor Air Temperature Sensor Fault E8 - Outdoor Discharge Temperature Sensor Fault E9 - Outdoor IPM Module Fault EA - Outdoor Current Detect Fault EE - Outdoor PCB EEPROM Fault EF - Outdoor Fan Motor Fault EH - Outdoor Suction Temperature Sensor Fault FX - Advanced Troubleshooting Codes - Contact Tech Support for Assistance P4 - Compressor Overload (If at initial startup, check that refrigerant valves are open) WARNING SIGNALS ON THE DISPLAY CL - Clean Filters

Press and hold the Turbo button on the remote for 5 seconds to change from Fahrenheit to Celsius and vice versa.

(On most newer models) With the unit ON, press the Swing left/right and swing up/down buttons simultaneously. The unit should display AC and will go into self-clean mode for 30 minutes. Some cracking noise is normal as the plastic will constrict with the heat and then expand again. After 30 minutes, you can use the unit again. If you want to stop the process before the 30 minutes, turn the unit off and back on.
