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.
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.
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 27).
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.Keepwindowcoveringsawayfromtheunittoprovidefreeairflow.

External Drain (for new construction or unit replacement)
When using an external drain system, the condensate is removed through either of two drain holes on the back of the wall sleeve. Select the drain hole which best meets your drainage situation and install the drain kit. Seal off the other with a cover plate.
Drain Tube Installation (See Figure 12)
1.Peel the backing tape off the gaskets and apply the sticky side to one cover plate and one mounting plate as shown in Details A and B.
2.Place the drain tube through the gasket and the mounting plate with the flange toward the wall sleeve.
3.Attach the drain tube assembly to one of the two drain holes at the rear of the wall sleeve. The large flange on the mounting plate is positioned at the bottom of the sleeve facing toward the sleeve, Detail B. When the drain tube is positioned at the desired angle, tighten the screws.
Cover Plate Installation
4.Mount the foam gasket to the cover plate. Using two #10 x ½" sheet metal screws (provided), attach the cover plate to the remaining drain hole. Make certain the large flange on the plate is positioned at the bottom of the sleeve.
5.Discard the additional cover plate, gasket, machine screws, and locknuts.
NOTICE
If the wall sleeve has not been installed, the drain tube must be rotated to a horizontal position until after the sleeve is installed. Tighten the mounting plate screws when the tube is in the proper position. Make certain that the four overflow slots at the rear of the wall sleeve are not blocked (See Figure 12).
When sealing the sleeve on the outside of the building, be careful NOT to let the sealant block the two condensate drain holes or the four overflow slots at the bottom flange of the sleeve.
Potential property damage can occur if instructions are not followed.
