Thank you for your decision to purchase the Friedrich Hazardgard (Hazardous Duty Room Air Conditioner). Your new Friedrich
has been carefully engineered and manufactured to give you many years of dependable, efficient operation, maintaining a
comfortable temperature and humidity level. Many extra features have been built into your unit to assure quiet operation, the
greatest circulation of cool, dry air, and the most economic operation.
This Installation and Operation Manual has been designed to insure maximum satisfaction in the performance of your unit. For
years of trouble-free service, please follow the installation instructions closely. We cannot overemphasize the importance of
proper installation. We have added new information to the basic instructions to help you achieve success.
Congratulations!
General Instructions
Here are some suggestions to help you use your
new Friedrich most efficiently:
1. Carefully read and follow the installation instructions.
2. Make sure the unit is the right capacity for the area to be
cooled. An undersized unit makes the unit work too hard,
using more electricity than needed and increases wear. An
oversized unit will cycle on and off too rapidly, and therefore
cannot control humidity as well.
3. When you first turn on your Friedrich, set the thermostat to
its coldest position to cool the room. When the desired
temperature is reached, turn the thermostat control toward
the “warmer” position until you hear a click and the
compressor goes off. The thermostat will then cycle the
compressor to maintain the selected temperature.
4. Clean the filter frequently (See Filter Information)
5. Do not block the air flow to and from the unit. Make sure the
louvers are directed to give even distribution of air
throughout the room. Caution: If air directed into a restricted
area such as a corner, this may cause the unit to cycle on and
off rapidly, which could damage your unit.
6. A dirty filter or improperly set controls can affect the cooling
ability of the unit.
7. If cooling is weak and you have verified that the filter is
clean and the controls are properly set, the unit may be low
on refrigerant, and you should call your Friedrich service
provider to check the unit.
8. Keep blinds, shades and drapes closed on the sunny side of
the room being cooled.
9. Proper insulation helps your unit maintain the desired inside
temperature.
