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.

Friedrich PTAC Digital Control and Unit Features

The new Friedrich digital PTAC has state of the art features to improve guest comfort, indoor air quality and conserve energy. Through the use of specifically designed control software for the PTAC industry Friedrich has accomplished what other Manufacturer’s have only attempted – a quiet, dependable, affordable and easy to use PTAC.

Below is a list of standard features on every Friedrich PTAC and their benefit to the owner.

Digital Temperature

By digitally monitoring desired room temperature the room is controlled more precisely than conventional systems.

Readout

The large, easy to read LED display can show either set-pointor actual room temperature as selected by owner.

 

 

 

When the unit is powered off the unit can be returned directly to heating or cooling mode by pressing the ‘Heat’ or

One-TouchOperation

‘Cool’ buttons without the confusing power up sequence of some controls. One-touchcontrol takes guesswork out

 

of unit control delivering a more enjoyable experience and eliminating front-deskcalls.

 

 

Three Fan Speeds

The Friedrich PTAC/PTHP units feature three fan speeds for the user to select from. This allows the user to

properly match the amount of airflow for their comfort level and also deliver's quiet performance.

 

 

 

Individual Mode and

By having separate control buttons and indicators for both fan and mode settings the Friedrich digital control

eliminates the confusion of previous digital PTACs. The accurate temperature setting provides greater guest

Fan Control Buttons

comfort than other systems.

 

 

 

 

The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing or

Quiet Start/Stop

stopping immediately. Upon call for cooling or heating the unit fan will run for five seconds prior to energizing the

Fan Delay

compressor. Also, the fan off delay allows for “free cooling” by utilizing the already cool indoor coil to its maximum

 

capacity by running for 30 seconds after the compressor.

 

 

Two-SpeedWall

When connected to a wall thermostat the user can select from high or low fan speed at the thermostat, unlike

competitive models that have only one speed selection. This allow more comfortable and quieter operation.

Thermostat Mode

Requires the use of Friedrich remote thermostat RT6 or equivalent thermostat with two speed fan output.

 

 

 

Remote Thermostat

Some applications require the use of a wall mounted thermostat. All new Friedrich PTACs may be switched from

Operation

unit control to remote thermostat control easily without the need to order a special model or accessory kit.

 

 

Internal Diagnostic

The Friedrich digital PTAC features a self diagnostic program that can alert maintenance to component failures

or operating problems. The internal diagnostic program saves properties valuable time when diagnosing running

Program

problems.

 

 

 

 

The self diagnosis program will also store error codes in memory if certain conditions occur and correct

Service Error Code

themselves such as extreme high or low operating conditions or activation of the room freeze protection feature.

Storage

Storing error codes can help properties determine if the unit faced obscure conditions or if an error occurred and

 

corrected itself.

 

 

Electronic

By limiting the operating range the property can save energy by eliminating “max cool” or “max heat” situations

common with older uncontrolled systems. The new electronic control allows owners to set operating ranges for

Temperature Limiting

both heating and cooling independently of one another.

 

 

 

 

When the PTAC senses that the indoor room temperature has fallen to 40° F the unit will cycle on high fan and

Room Freeze

the electric strip heat to raise the room temperature to 46° F then cycle off again. This feature works regardless

of the mode selected and can be turned off. The control will also store the Room Freeze cycle in the service code

Protection

memory for retrieval at a later date. This feature ensures that unoccupied rooms do not reach freezing levels

 

 

where damage can occur to plumbing and fixtures.

 

 

Random Compressor

Multiple compressors starting at once can often cause electrical overloads and premature unit failure. The random

restart delay eliminates multiple units from starting at once following a power outage or initial power up. The

Restart

compressor delay will range from 180 to 240 seconds.

 

 

 

Digital Defrost

The Friedrich PTAC uses a digital thermostat to accurately monitor the outdoor coil conditions to allow the heat

pump to run whenever conditions are correct. Running the PTAC in heat pump mode saves energy and reduces

Thermostat

operating costs. The digital thermostat allows maximization of heat pump run time.

 

 

 

20

Instant Heat

Heat pump models will automatically run the electric heater to quickly bring the room up to temperature when initially

energized, then return to heat pump mode. This ensures that the room is brought up to temperature quickly without the

Heat Pump Mode

usual delay associated with heat pump units.

 

 

 

Even Heat

The digital control monitors indoor conditions to ensure that the room temperature is within five degrees of the setpoint.

If necessary the unit will cycle the electric heat to maintain the temperature. This feature ensures guest comfort by

Monitoring

delivering the heating benefits of an electric heater while maintaining the efficiency benefits of a heat pump.

 

 

 

 

The owner may choose between fan cycling or fan continuous mode based on property preference. (Note: Even heat

Separate Heat/Cool .

monitoring and quiet start/stop fan delay only operate in fan cycle mode) Fan continuous mode is used to keep constant

airflow circulation in the room during all times the unit is ‘ON’. Fan cycle will conserve energy by only operating the

Fan Cycle Control

fan while the compressor or electric heater is operating. The ability to set the fan cycling condition independently

 

between heating and cooling mode will increase user comfort by allowing the choice of only constantly circulating

 

air in the summer or winter time. Unlike other PTAC brands that only allow one selection.

 

 

Emergency Heat

In the event of a compressor failure in heat pump mode the compressor may be locked out to provide heat through the

resistance heater. This feature ensures that even in the unlikely event of a compressor failure the room temperature can

Override

be maintained until the compressor can be serviced.

 

 

 

Desk Control

All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy management system.

Controlling the unit from a remote location like the front desk can reduce energy usage and requires no additional

Ready

accessories on the PTAC unit.

 

 

 

Indoor Coil Frost

The frost sensor protects the compressor from damage in the event that airflow is reduced or low outdoor temperatures

cause the indoor coil to freeze. When the indoor coil reaches 30° F the compressor is disabled and the fan continues to

Sensor

operate based on demand. Once the coil temperature returns to 45° F the compressor returns to operation.

 

 

 

Ultra-QuietAir

The new Friedrich PD series units feature an indoor fan system design that reduces sound levels without lowering airflow

System

and preventing proper air circulation.

 

 

High Efficiency

The Friedrich PTAC benefits from quality components and extensive development to ensure a quiet, efficient and

dependable unit.

 

 

 

Dual Motor

Friedrich's new dual motor design allows for the quietest and most efficient units yet.

 

 

Rotary Compressor

High efficiency rotary compressors are used on all Friedrich PTACs to maximize durability and efficiency.

 

 

Stainless Steel Endplates

Outdoor coil endplates made from stainless steel reduce corrosion on the outdoor coil common with other coil designs.

 

 

Diamonblue

Diamonblue (seacoast protection) protects the outdoor coil from harsh environments. Comes standard on all

Technology

PTAC units.

 

 

Top Mounted

All Friedrich PTAC return air filters feature an anti-microbialelement that has proven to prevent mold and bacterial

washable and reusable and are easily accessed from the top of the unit without the removal of the front cover.

 

 

Filtered Fresh Air

Friedrich PTAC units are capable of introducing up to 75 CFM of outside air into the conditioned space. The

Intake

outdoor air passes through a mesh screen to prevent debris from entering the air stream.

Fresh Air Vent Control

The vent control lever is located on the left side of the unit, behind the front panel.

NOTE: The vent door shipping hardware must be removed before usingtheventcontrollever. Seepage17,Figure21,(Remove Shipping Screw from Vent Door if present).

When vent door is set to CLOSE,only the air inside the room is circulated and filtered, See Figure 28.

To remove the air filters, grasp the top of the filter and lift out of the front cabinet. Reverse the procedure to reinstall the filters.

Cleanthefilterswithamilddetergentinwarmwater,andallowthemtodry thoroughly before reinstalling.

Coils & Chassis

NOTE: Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser. The use of harsh cleaning materials may lead to deterioration of the aluminum fins or the coil end plates.

The indoor coil and outdoor coils and base pan should be inspected periodically (annually or semi-annually)and cleaned of all debris (lint, dirt. leaves,paper,etc.)asnecessary. Underextremeconditions,morefrequent cleaning may by required. Clean the coils and base pan with a soft brush and compressed air or vacuum. A pressure washer may also be used,

however, you must be careful not to bend the aluminium fin pack. Use a sweeping up and down motion in the direction of the vertical aluminium fin pack when pressure cleaning coils.

NOTE: It is extremely important to insure that none of the electrical and/or electronic parts of the unit get wet. Be sure to cover all electrical components to protect them from water or spray.

Decorative Front

The decorative front and discharge air grille may be cleaned with a mild soap or detergent. Do NOT use solvents or hydrocarbon based cleaners suchasacetone,naphtha,gasoline,benzene,etc.,tocleanthedecorative front or air discharge grilles.

Use a damp (not wet) cloth when cleaning the control area to prevent waterfromenteringtheunit,andpossiblydamagingtheelectroniccontrol.

Fan Motor & Compressor

The fan motor & compressor and are permanently lubricated, and require no additional lubrication.

Wall Sleeve

Inspecttheinsideofthewallsleeveanddrainsystemperiodically(annually or semi-annually)and clean as required.
