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 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

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.

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.

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

Figure 2
•	For minor obs tr uc ti on 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 solid fence, wall or other heat rejecting device like a condensing unit, a minimum distance of 36" should be kept.

Wall Sleeve Installation Instructions (PDXWSA)

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.

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.

For Deep WallInstallation (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.

Figure 3

Typical Wall Sleeve Installation

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(See Figure 9, Page 8).

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.

PXDR10DrainKit Installation Instructions(optionalfornew construction)

NOTE:. Determine whether drain will be located within the wall, on the indoor side, or will drain to the exterior of the building. Follow appropriate instructions below depending on your particular type of installation.

InternalDrain

NOTE:. If installing an internal drain, you MUST install a drain kit on the wall sleeve before the wall sleeve is installed.

1.Refer to Figure 11 and locate the drain within the “Preferred”

area of best drainage. Maintain at least a ½” clearance from the embossed area.

2.Using the mounting plate with the ½” hole as a template, mark and drill two, 3/16” mounting holes and a ½” drain hole in the sleeve bottom .

NO FOAM INSULATION

IF THE DRAIN MUST BE

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.
