Section II - DeepWall Installation (PXWE)
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 a wall
sleeve extension:
1 Provision must bemade 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 a drip
panel. Refer to drawing for more information.
6. Condensate notchesand overflow slotsmust 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 itin thewall. Refer to Figure8 fora guide forfabrication
of acondensate drip panel.Thepanel MUSTextend thefulldepth
of the wall sleeve and the wall sleeve extension.
Pay particular care in sealing and caulking the panel where it
makescontact with thewall sleeve(seeFigure8).After installation
in thewall, 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.

DigitalControlUserInputConfiguration
The adjustable control dipswitches 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 1-4can 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 thefan only when there is a demand for
the compressor or heater. As an option the fan may be set to
'continuous' mode by switching Dip Switch 5 to 'ON' positionto
run the fan continuously while the unit is powered on.
Toensure that the room temperature is maintained evenlywhile
in fan cycle mode the Even Temp Load Anticipation feature is
enabled. Quiet Fan Belay isalso 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 15 seconds after heating
cycles.
3) Room Freeze Protection - Switch 6
Unitsare shippedfrom thefactorywith the roomfreeze protection
disabled. Room Freeze Protection can be switched on at the
owner's preference by moving Dip Switch 6 to 'ON'. This feature
will monitor the indoor room conditions and inthe event that the
room falls below 40°F the unit will cycle on high fan with the
electric heater. This occurs regardless of mode.
4) Emergency Heat Override - Switch 7
In the unlikely event of a compressor failure a heat pump unit
may be switched to operate in only the electric heat mode until
repairs can be made. Moving Dip Switch 7 to 'ON'.
Note: PTAC must be disconnected from power supply
when making any configuration changes.

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 maintain theroom
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 on the fan mode selected,either
continuous or cycling. Dip switch 5 controls the fan mode, see
page 16 for setting.
Whenthe outdoorcoiltemperaturefalls below 30°Ffor morethan
2 minutesthe unitwill operate the resistance heaters and notthe
