Congratulations!
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.
General Instructions
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 infor-
mation to the basic instructions to help you achieve proper installation.
WARNING
Refrigeration system under high pressure.
Do not puncture, heat, expose to flame or incinerate.
Only certified refrigeration technicians should service
this equipment.
R410A systems operate at higher pressures than R22
equipment. Appropriate safe service and handling
practices must be used.
Only use gauge sets designed for use with R410A. Do
not use standard R22 gauge sets.
WARNING
Please read this manual thoroughly prior to equipment
installation or operation.
It is the installer’s responsibility to properly apply and
install the equipment. Installation must be in
conformance with the NFPA 70-2008 National Electric
Code or current edition, International Mechanic Code
2009 or current edition and any other applicable local
or national codes.
Failure to do so can result in property damage,
personal injury or death.
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 very well.
3.
When you first turn on your Friedrich, set the thermostat to
its coldest position to cool the room. When the desired tem-
perature 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 through-
out 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 room insulation helps your unit maintain the desired
inside temperature.
10. Whenever possible, shade west-facing windows with aw-
nings , trees, or window tinting.
11. Keep window treatments away from the unit to provide free
air flow.
Here are some suggestions to help you use your new Friedrich most efficiently:
Your safety and the safety of others are very important.
We have provided many important safety messages in this manual
and on your appliance. Always read and obey all safety messages.
This is a safety Alert symbol. This symbol alerts you
to potential hazards that can kill or hurt you and

All safety messages will follow the safety alert
symbol with the word “WARNING” or “CAUTION”.
These words mean:

avoided, can result in severe
personal injury or death and damage
to product or other property.
Indicates a hazard which, if not
avoided, can result in personal injury
and damage to product or other property.
All safety messages will tell you what the potential hazard is, tell you
how to reduce the chance of injury, and tell you what will happen if
the instructions are not followed.
Indicates property damage can
occur if instructions are not followed
