Congratulations
Thank you for your decision to purchase Friedrich. 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.
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.
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 being 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. Clean the filter frequently (See Routine Maintenance, Page 26).
4. Do not block the air flow to and from the unit.
5. A dirty filter or improperly set controls can affect the cooling
ability of the unit.
6. If cooling is weak and you have verified that the filter is clean
and the controls are properly set, the unit may need service and
you should call your Friedrich service provider to check the unit.
7. Keep blinds, shades and drapes closed on the sunny side of the
room being cooled to reduce radiant heat.
8. Proper insulation helps your unit maintain the desired inside
temperature.
9. Whenever possible, shade south and west facing windows.
10. Keep window coverings away from the unit to provide free air flow.
WARNING

PTACInstallationRecommendations
PTAC units should be installed
no closer than 12" apar t when
two units are side by side. If
three or more PTAC units are to
operate next to one another allow
a minimum of 36" between units
Also, a vertical clearance of 60"
should be maintained between
units installed. In the interior
of the room the unit should be
located a minimum of 1/4" from
the floor and a minimum of 36"
from the ceiling.
FRP001
• Fo r mino r ob str u c tion s
such as lamp poles or small
shrubbery a clearance of
12" from the outdoor louver
should be maintained.
TYPICAL BUILDING ( PLAN VIEW )
• For major obstructions such
as a solid fenc e, wal l or
other heat rejecting device
like a condensing unit, a
minimum distance of 36 "
should be kept.
