WARNING

Read Installation Operation Manual

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.

Thank you for your decision to purchase Friedrich. Your new Friedrich has been carefully engineered and manufactured to give you many years of dependable,

efcient 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.

and the controls are properly set, the unit may need service and

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 lter frequently (See Routine Maintenance, Page 27).

4. Do not block the air ow to and from the unit.

5. A dirty lter or improperly set controls can affect the cooling

ability of the unit.

6. If cooling is weak and you have veried that the lter is clean

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 ow.

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:

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.

Installation Checklist

q Inspect all components and accessories for damage before and after

installation.

q Remove the cardboard wall sleeve support and grill weatherboard.

q Check for proper wall sleeve installation in accordance with the wall

sleeve installation instructions.

q Check for a subbase kit or other means of structural support which

is required for ALL installations projecting more than 8" into room.

q Install the recommended Condensate Drain Kits for complete

condensate removal.

q Ensure that the chassis is installed in a 16" high x 42” wide wall sleeve

that is no deeper than 13 ¾". A bafe kit is required if the sleeve

exceeds that depth.

q Ensure that chassis and chassis front cover are installed and secured

properly.

q Ensure that drapes, bed, bedspread, furniture, etc. DO NOT block

either return or discharge air grilles.

q Inspect the condenser air inlet and outlet for any obstructions

(shrubbery, etc.)

q Ensure that 'reset' button is pressed on LCD device (only on cord

connected models).

PTAC Installation Recommendations

36" MIMUMUM, MAJO

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 oor and a minimum of 36"

from the ceiling.

TYPICAL WINDOW

VIEW: OUTSIDE BUILDING ELEVATION

For PTACs on the ground floor or anytime obstructions are present, use the following guidelines:

Figure 2

• Fo r m i n or obstruc t i o n s such as lamp poles or small shrubbery a clearance of

12" from the outdoor louver

should be maintained.

• For major obstructions such

as a sol id fence, wall or

other heat rejecting device

like a condensing unit, a

minimum dist ance of 36"

should be kept.

installation arrangements. By following these simple recommendations you can be condent that your Friedrich PTAC will provide years of worry free operation.

Wall Sleeve Installation Instructions (PDXWS)

NOTICE

DO NOT allow any pitch toward the inside.

Flashing on all 4 sides of the opening is recommended.

Potential property damage can occur if instructions are not followed.

NOTE: Insure that the unit is only installed in a wall structurally adequate to support the unit including the sleeve, chassis and accessories. If the sleeve

projects more than 8" into the room, a subbase or other means of support MUST be used. Please read these instructions completely before

attempting installation.

WARNING

Falling Object Hazard

Not following Installation Instructions for mounting your air conditioner can result in property damage, injury, or death.

For Deep Wall Installation (Greater than 13 1/4") See Page 9

The following instructions apply ONLY to walls less than 13 ¼" in depth.

1. The PXDR10 Drain Kit (optional for new construction) see page 10 if applicable, must be installed before the wall sleeve is installed into the wall.

2. The External Drain (for new construction or unit replacement) see page 11, if applicable, must be installed before the wall sleeve is installed into the wall.

3. From inside the building, position the wall sleeve in the opening and

push it into the wall until it protrudes at least ¼” on the outside. Do

not allow sleeve to be pulled. (See Figure 11, Page 10).

4. Position the wall sleeve with a slight tilt towards the outside to facilitate condensate drainage. It should be level side-to-side and the front should be ¼ bubble higher than the back.

NOTE: Follow all wall system manufacturer installation instructions. For sunrooms and modular buildings, adhere to their installation instructions for

supporting and sealing sleeve to their frames. All wall and window/wall installations must provide for proper drainage. In applications where the drain holes on the PTAC wall sleeve are not exposed beyond the wall an internal drain system is recommended. It is the installer's responsibility

to ensure there is adequate drainage for the PTAC unit.

5. Drill two 3/16" holes through each side of the sleeve approximately 4" from top and 4" from bottom of sleeve. Screw four #10 x 1"

screws (included) or appropriate fasteners for your installation, through the holes in the sides of the wall sleeve.

6. Apply sealant around the wall sleeve where it projects through the

inside and outside wall surfaces. Apply the sealant to the screw

heads or the tops of the fasteners used in Step #5.

7. If the chassis and exterior grille are to be installed later, leave the weatherboard and center support in place, otherwise remove and dispose of them. (See Figure 13, Page 12).

8. Provide a support lintel if the wall sleeve is installed in a concrete or masonry wall (See Figure 10, Page 9).
