If thewall isthicker thanallowed 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 awall
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 mustallow for the proper

mounting of the grille.

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

5. Fabricateand install metalflashing inwall to serveas adrip

panel. Referto drawing for more information.

6. Condensate notches and overflow slotsmust bekept 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 itin the wall. Referto Figure8 fora guide forfabrication

of acondensate drip panel.The panel MUST extend thefulldepth
of the wall sleeve and the wall sleeve extension.

Pay particular care in sealing and caulking the panel where it
makescontact withthewall sleeve(seeFigure8).After installation

in thewall, secure withfasteners through the sides. Use agood

grade of silicone sealant around the sleeveextension. Seal all
exposed screw heads. When the installation is complete, the

outside grille should be attached to the wall sleeve extension.

DigitalControlUserInput Configuration

The adjustable control dip switches are located at the lower left hand portion of the digital Smart Center. The inputs are only visible
and accessible with the front cover removed from the PTAC.

Dip Switch Setting

1) Electronic Temperature Limiting - Switches 1-4

The digital control is set from the factory to allow a tempera-
ture range between 60°F and 90°F in both heating and cooling

mode. Dip Switches 1-4 can be used to set high and low limits

for either heating or cooling or both.

From the factory all four switches are in the up 'ON' position.
The charts to the right show the available electronic limiting
ranges.

2) Fan Cycle Control - Switch 5

All PTACs are shipped from the factory with Dip Switch 5 in the

'OFF' position to cycle the fan only when there is ademand for
the compressor or heater.As an option the fan may be set to
'continuous' mode by switching Dip Switch 5 to 'ON' position to
run the fan continuously while the unit is powered on.
Toensure that the room temperature is maintained evenly while
in fan cycle mode the Even Temp Load Anticipation feature is
enabled. Quiet Fan Belay is also enabled in fan cycle mode to
lessen the acoustical change between compressor start up and
shut off by running the fan for 5 seconds before each demand
cycle, and 30 seconds after cooling or 15seconds after heating
cycles.

3) Room Freeze Protection - Switch 6
Unitsare shippedfrom thefactory with the room freeze protection

disabled. Room Freeze Protection can be switched on at the
owner's preference by movingDip Switch 6 to 'ON'. This feature

will monitor the indoorroom conditions and in the event that the

room falls below 40°F the unit will cycle on high fan with the
electric heater.This occurs regardless of mode.

Pressing the 'Heat' buttonwhile theunit isin anymode, 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 onand operate asa heat pumpto maintaintheroom
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.

Thefan operation isdependent onthe fan mode selected, either
continuous or cycling. Dip switch 5controls the fan mode, see
page 16 for setting.

Whenthe outdoorcoiltemperaturefalls below 30°Ffor morethan
2 minutesthe unitwill operate the resistanceheaters and not the
compressor. When the outdoor coil temperature reaches 45°F
the compressor will be allowed to operate again.

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- CoolingMode

Isunitsizedtoroomsizeareaand heatloaddemand?

The number of people in the room, numberof 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.

Isthe outdoortemperature60°F orbelow?

The unit is designed for outdoor temperatures above 60°R

Isthe indoortemperature80°For above?

Ambient indoor temperatures of80°F or abovewill take a longer

period of run time to cool down the area. Long run times may
indicate that the unit isundersized.

Isindoorhumidityhigh?

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

Hasthe heat load been increasedby additional devicessuch

sizing of the unit. Friedrich recommends that you consult with
an applications engineer for proper sizing.

Isthe outdoortemperaturo70°For above?

The unit is designed for outdoor temperatures below 70°R

Is the indoor temperature 60°F or below? Ambient indoor

temperatures of 60°F or below will take a longer period of run
time to heat the area. Long run times may indicate that the unit

is undersized.
