2.2 HINTS FOR ECONOMICAL OPERATION

Adjust the temperature to achieve moderate comfort levels. Excessively low or high temperatures
waste energy.
Improve performance by keeping windows and doors closed.
Limit energy usage [run time] by using the TIMER function.
Do not block air inlets or outlets. Poor performance, increased running costs and reduced product
life will result.
Inspect the air filters periodically, and clean them when needed.
Disconnect the power source if unit will not be used for a long period.
