Section II - Deep Wall Installation (PXWE)

If the wall is thicker than allowed in the notes in Figure 6, a sheet metal wall sleeve extension and flashing MUST be used.

Installation Instructions for the PXWE - 4" Wall

Sleeve Extension

The following points MUST be considered when installing a wall sleeve extension:

1 Provision must be made to direct excess condensate from the back of the wall sleeve into the extension then outside the building or to a drainage system.

2. Air baffles must be mounted to properly direct air flow to and from the condenser.

3. Thewall sleeve extension design must allow for the proper mounting of the grille.

4. Caulking is required at all sites where condensate or external water could potentially infiltrate into the building.

5. Fabricate and install metal flashing in wall to serve as a drip panel. Refer to drawing for more information.

6. Condensate notches and overflow slots must be kept clear of sealant and gaskets so condensate can flow freely into the wall sleeve extension.

NOTE: Improper fabrication or installation of a wall sleeve extension will impair PTAC performance.

Extension Installation

Secure the wall sleeve extension to the wall sleeve before installing it in the wall. Refer to Figure 8 for a guide for fabrication of a condensate drip panel. The panel MUST extend the full depth of the wall sleeve and the wall sleeve extension.

Pay particular care in sealing and caulking the panel where it makescontact with thewall sleeve (see Figure8). After installation in the wall, secure with fasteners through the sides. Use a good grade of silicone sealant around the sleeve extension. Seal all exposed screw heads. When the installation is complete, the outside grille should be attached to the wall sleeve extension.

TemperatureDisplay

The Ffiedfich digital PTAC is shipped from the factory to display the desired room temperature on the LED readout.

The unit can be configured to display the room temperature by simultaneously pressing the 'Cool' and 'High Fan' buttons for three seconds the display will show an 'F,"for one seconds to acknowledge the change. The unit will display the setpoint whenever the 'Temp' A or v buttons are pressed and then switch back to room temperature.

To revert back to displaying the setpoint only press the 'Ceor and

'LowFan' buttons for three seconds simultaneously, the unit will display an'S' for one seconds to acknowledge the change.

°Fvs. °C Display

The unit is factory configured to display all temperatures in degrees Fahrenheit (°F). To switch to degrees Celsius press the 'Fan Only' and 'Low Fan' buttons simultaneously for three seconds. The display will show a 'C' as acknowledgement of the change.

To revert back to oFpress the 'Fan Only' and 'Low Fan' buttons simultaneously for three seconds. The display will show an 'F' as acknowledgement of the change.

Cooling Mode

Pressing the 'Cool' button while the unit is in any mode, including off, will put the unit into cooling mode. Adjust the temperature readout to the desired room temperature and the unit will cycle the compressor on and off to maintain a comfortable room. The compressor will come on anytime that the room temperature is 1.8°F above the desired temperature. The fan operation is dependent on the fan mode selected, either continuous or cycling.

See page 16 for fan cycle control.

Heating Mode

Pressing the 'Heat' button while the unit is in any mode, including off, will put the unit into heating mode.

Heat Pump Models (PDH)

When the 'Heat' button is pressed initially the unit will energize the electric resistance heat to quickly bring the room to the set temperature. When the desired room temperature falls

1.8°F below the desired set temperature the unit will cycle the compressor on and operate as a heat pump to maintain the room temperature while running more efficiently than resistance heat only models. If the room temperature should fall more than 5°F from the set temperature the unit will run the resistance heater.

The fan operation is dependent on the fan mode selected, either continuous or cycling. Dip switch 5 controls the fan mode, see page 16 for setting.

When the outdoor coil temperature falls below 30°Ffor more than

2 minutes the unitwill operate the resistance heaters and not the compressor. When the outdoor coil temperature reaches 45°F the compressor will be allowed to operate again.

After pressing the 'Heat' button, adjust the temperature readout to the desired room temperatureand the unit will cycle the resistance heat on and off to maintain a comfortable room. The heater will come on anytime that the room temperature is 1.8°F below the desired temperature. The fan operation is dependent on the fan mode selected, either continuous or cycling. Dip switch 5 controls the fan mode, see page 16 for setting.

Emergency Heat Operation

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. Dip switch 7 controls the emergency heat setting, see page 16.

Fan Mode

Fan Only

Pressing the 'Fan Only' button will run the fan to allow for air circulation in the room without operating the compressor or heater regardless of the room or set temperature. The fan speed selection is made by pressing either the 'High Fan' or 'Low

Fan' button.

Cycle/Continuous

The owner may choose between fan cycling or fan continuous mode based on property preference.

(Note: Even heat 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 while the compressor or electric heater is operating. Dip switch 5 controls the fan mode, see page 16 for setting.

K. BasicTroubleshootingTechniques

Being familiar with the sequence of operation on Standard Controlled Operating Units or the operation of the Remote Thermostat

Controlled Units is important. The following questions and answers may help to identify performance problems.

EnvironmentalEffects- Cooling Mode

Is unitsizedto roomsize areaand heat loaddemand?

The number of people in the room, number of electrical devices, solar gains, etc. are all variable items that can affect proper sizing of the unit. Friedrich recommends that you consult with an applications engineer for proper sizing.

Is the outdoortemperature 60°F or below?

The unit is designed for outdoor temperatures above 60°R

Isthe indoortemperature 80°For above?

Ambient indoor temperatures of 80°F or above will take a longer period of run time to cool down the area. Long run times may indicate that the unit is undersized.

Is indoorhumidityhigh?

This condition will cause the unit to operate longer to remove humidity before noticing any cooling effect.

Has the heat load been increased by additional devicessuch as computerequipment, or has the roomarea been increased where the unit is located?

If conditions have changed, the unit may not be able to cool and condition as effectively as previously planned.

Environmental Effects- Heating Mode
