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.
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.
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.
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 others. All safety messages will follow the safety alert symbol with the word “WARNING” or “CAUTION”. These words mean:
WARNING
CAUTION
Indicates a hazard which, if not 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.
NOTICE
Indicates property damage can occur if instructions are not followed.

PTACInstallationRecommendations
For proper PTAC unit performance and maximum operating life refer to the minimum installation clearances below:
Figure 1
PTAC units should be installed no closer than 12" apart 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.

3.Remove the backing from the gasket and mount it on the flat side of the mounting plate. (See Figure 12, Page 11). Insert the drain tube through the hole in the gasket and mounting plate so the tube flange will be against the wall sleeve.
4.Position the assembly beneath the drilled holes and secure it with #
10-24x ½" machine screws and lock nuts provided . Seal the tops of the screws with silicone caulking.
5.Use ½" ID copper tube, PVC pipe, or vinyl hose (obtained locally) to connect the internal drain tube to the drain system in the building.
6.Referring to Figure 12,Detail A, Page 11,locate and assemble the two cover plates and gaskets over the drain holes at the rear of the wall sleeve.Attach them with the #10 sheet metal screws provided.Make certain that the four overflow slots at the rear of the wall sleeve are not blocked (See drawing of the back of the sleeve Figure 12, Page 11).
7.If a deep wall extension (PDXWSEXT) is used, after installing the field supplied flashing,caulk as required. Be sure to caulk around the flashing and the wall sleeve where the hole was drilled for the drain tube.
