Congratulations

ThankyouforyourdecisiontopurchaseFriedrich. YournewFriedrichhasbeencarefullyengineeredandmanufacturedtogiveyoumanyyearsofdependable, 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-freeservice, 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.

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 -2008National 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.

qRemove the cardboard wall sleeve support and grill weatherboard.

qCheck for proper wall sleeve installation in accordance with the wall sleeve installation instructions.

qCheck for a subbase kit or other means of structural support which is required for ALL installations projecting more than 8" into room.

qInstall the recommended Condensate Drain Kits for complete condensate removal.

qEnsurethatthechassisisinstalledina16"highx42”widewallsleeve that is no deeper than 13 ¾". A baffle kit is required if the sleeve exceeds that depth.

PTAC Installation Recommendations

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 operatenexttooneanotherallow 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 minor obstructions 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 (PDXWS)

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

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

1.ThePXDR10DrainKit(optionalfornewconstruction)seepage10 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.

NOTE: Determinewhetherdrainwillbelocatedwithinthewall,onthe indoorside,orwilldraintotheexteriorofthebuilding. Follow appropriate instructions below depending on your particular type of installation.

Internal Drain

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.

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 tubethroughtheholeinthegasketandmountingplatesothetube flange will be against the wall sleeve.
