FOR OUTDOOR UNITS WITH ELECTRIC HEATERS (MOST ARCTIC VERSIONS)
When the outdoor temperature is below 0°C (32°F ), we strongly recommend keeping the unit energized at all times to ensure smooth and uninterrupted performance.
Full system-rated capacity and efficiency is obtained with the standard rating conditions as developed by the testing and rating agencies. Deviations from rating conditions, especially atmospheric conditions, will be compansated by the variable speed compressor, within certain limitations. Heat pump systems function by exchanging energy, in the form of heat, between the indoor air and the outdoor ambient air (atmospheric). The system's net cooling or heating capacities and efficiencies change with atmospheric conditions, as well as indoor air conditions (such as temperatures and humidity levels).
Capacity of the system required for a specific area or application must be determined professionally using detailed calculations, which are based on several internal and external factors.
To further optimize the performance of your unit, do the following: · Keep doors and windows closed. · Limit energy usage by using TIMER ON and TIMER OFF functions. · Do not block air inlets or outlets. · Regularly inspect and clean air filters.

Setting Horizontal Angle of Air Flow
The horizontal angle of the airflow must be set manually. Locate the deflector rod (See Fig.B) and manually adjust it to your preferred direction. For some units, the horizontal angle of the airflow can be set by remote control. Please refer to the Remote Control Manual.
NOTE ON LOUVER ANGLES
When using COOL or DRY mode, do not set the louver at a high vertical angle for extended periods of time. This can cause water to condense onto the louver blade, which will drop to your floor or onto furnishings. (See Fig. A)
When using COOL or HEAT mode, setting the louver at a high vertical angle can reduce the performance of the unit, due to restricted air flow.
Do not move louver by hand. This will cause the louver to go out of sync. If this occurs, turn off the unit and the breaker for a few seconds, then restart the unit. This will reset the louver.
