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.

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.

Product 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 benifit to the owner.

DIGITAL TEMPERATURE READOUT

INDIVIDUAL MODE & FAN CONTROL BUTTONS

QUIET START/STOP FAN DEL AY

REMOTE THERMOSTAT OPERATION

INTERNAL DIAGNOSTIC PROGRAM

FACTORY RUN-TEST

By digitally monitoring the desired room temperature, the room is controlled more precisely than con-

ventional systems. The large, easy-to-read LED display can show either the set point or actual room

temperature as selected by owner.

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 comfort than other systems.

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

ing or stopping immediately. Upon call for cooling or heating, the unit fan will run for ve seconds prior to energizing the 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.

Some applications require the use of a wall-mounted thermostat. All new Friedrich PTACs may be switched from unit control to remote thermostat control easily without the need to order a special model or accessory kit.

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 problems.

Factory run-tested units reduce problems in the field.

ELECTRONIC TEMPERATURE LIMITING

ROOM FREEZE PROTECTION

RANDOM COMPRESSOR RESTART

CONDENSATE REMOVAL SYSTEM

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 operat-

ing ranges for both heating and cooling independently of one another.

When the PTAC senses that the indoor room temperature has fallen to 50°F, the unit will cycle on the fan (high) and the electric strip heat to raise the room temperature to 55°F, and then cyc feature works regardless of the mode selected and can be turned off.

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

The random power up. The compressor delay will range from 120 to 240 seconds.

Condenser fan utilizes slinger ring technology to pick up condensate from the base pan and disperse it on

to the condenser coil where it evaporates. This helps to cool the coil and increase the energy efciency of the unit.

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

le off again. This

DIGITAL DEFROST

THERMOSTAT

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

HIGH EFFICIENCY

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 usual delay associated with heat pump units.

The owner may choose between fan cycling or fan continuous mode based on property preference. Fan continuous mode is used to keep constant air ow circulation in the room during all times the unit is ‘ON’. Fan cycle will conserve energy by only operating the fan while the compressor or electric heater is operating. ability to set the fan cycling condition independently between heating and cooling mode will increase user comfort by allowing other PTAC brands that only allow one selection).

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 be maintained until the compressor can be serviced.

All Friedrich digital PTACs have low voltage terminals ready to connect a central desk control energy management system. Controlling the unit from a remote location like the front desk can reduce energy usage and requires no additional accessories on the PTAC unit.

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 33°F, the compressor is disabled and the fan continues to operate based on demand. Once the coil temperature returns to 59°F, the compressor returns to operation.

The PZ-Series units feature an indoor fan system design that reduces sound levels without lowering

airow or preventing proper air circulation.

The Friedrich PTAC has been engineered so that all functional systems are optimized so that they work

together to deliver the highest possible performance.
