most flexible selection of function controls, and high economy of opemfon.
There are many things you can do in and around your home to save more money - and even increase the efficiency and
long life of your Friedrich unit. Here are a few examples:
How to Set Thermostat: When you frst turn on your air conditioner, select the highest fan speed and set the
thermostat to its coldest position to cool the room. When the desired temperature is reached, turn the thermostat
control toward "warmer" until the compressor goes off. The thermostat will then cause the compressor to go on
and off to maintain this selected temperature. You can adjust the fan speed lbr optimum air circulation.
2. Do not block the flow of air to and from the unit - make sure the louvers are directed to give even distribution of
air throughout the room. Caution: If air is obstructed and/or deflected back into the air conditioner, this may cause
the unit to cycle on and off rapidly, which could damage your unit.
3. Adequate insulation - walls, ceilings, and below floors - can save up to 50% of the cost of cooling in most areas of
the country.
4. Caulking: in well insulated homes, air leaks around doors, windows, lighting and plumbing fixtures can account
lBr as much as 30% of the load on heating and cooling systems. See that all these areas are well caulked.
5. Install weather stripping (metal is preferable to fel0 around exterior doors and windows.
6. Have a fireplace'? Be sure the damper is closed during air conditioner operation.
7. When it's time to reroofor repaint the outside of your home, choose light colors. They reflect heat instead of absorbing
it.
8. Shade your outside walls (especially on the wes0 from the direct sun; most importantly, shade the unit itself.
Trees and shrubs provide natural shading, but make sure they don't block the air flow around the unit. If natural
shade isn't present, awnings are the best solution lbr shading the unit and the windows.
Also, avoid areas where too much dust or pollen would be drawn into the air conditioner.
9. Inside the house, use blinds, screens, or drapes on windows exposed to the sun. They will reduce your cooling needs.
(Lined or insulated draperies will also help cut heating costs in winter).
10. Make sure your attic area is properly vented. In addition, consider installing turbine or power ventilators to help
remove hot air from your attic.
11. Keep your Friedrich unit clean. Use a vacuum cleaner attachment lbr accessible parts, but take care not to damage
them. Clean the reusable filter at least twice a mouth.
12. Set the thermostat at a higher temperature - save 5% in energy usage lBreach degree of temperature over 72°E
These are the most important suggestions lbr saving money on cooling costs. Some, however, may not be applicable to
your house or area. Check with your local utility company lbr more specialized inlbrmafon.
