Section II - DeepWall Installation(PXWE)
If the wail 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:
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 airflow to and
from the condenser.
3. The wail sleeve extension design must allow for the proper
mounting of the grille.
4. Caulking is required at ansites where condensate or external
water could potentially infiltrate into the building.
6. Condensate notches and overflow slots must be kept clear
of sealant and gaskets so condensate can flow freely intothe
wall sleeve extension.
NOTE: Improperfabrication or installationof a wall sleeveextension
will impair PTAC performance.
Extension Installation
Secure the wall sleeveextension to the wail 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 wail sleeve and the wail sleeve extension.
Payparticular care in sealingand caulkingthe panelwhere itmakes
contact with the wall sleeve (see Figure 8). 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.
5. Fabricate and install metal flashing in wall to serve as a drip
panel. Refer to drawing for more information.

RemoteThermostatSelection& WiringGuidelinesfor
PackagedTerminalAirConditioners
Follow the instructions and recommendations of the thermostat
manufacturer for installation and wiring. Do not use a conventional
heat pump thermostat with emergency electric heat selection for
our heat pump units. Our units make an automatic decision about
turning on electric heat if the heating demand cannot be met by the
heat pump due to low outdoor temperatures.
Manual Changeover Thermostat
For Heat Pump equipped units: A single stage, heat/cool
thermostat with aterminalfor a reversingvalve operation isrequired.
Terminal "B" should be continuously energized in the heat mode
and terminal "G" should be energized whenever there is a call for
heating or cooling. Typically, a heat/cool thermostat designed for
use with electric heat systems will meet the above requirements.
NOTE: This unit is designed for use with a single stage thermostat only. Improper application of the thermostat may result in property
damage, personal injury or death.
Honeywell Thermostat Terminal Designation:
TERMINAL LETTER OPERATION CONTACT MADE
Y Cooling During call for cooling.
W Heating During call for heating.
G Fan Continuous if the slider is inthe "Fan" position,otherwise, intermittent.
C Common Terminal For thermostats requiring a common terminal
R 24 V to the thermostat Directly from the transformer
B (Heat Pump units Only) Reversing Valve Made continuously during call for heating.
For Non-Heat Pump equipped units: A single stage cooling and heating thermostat is required. Terminal "G" should be
energized whenever a call for heating or cooling is made. Typically a heat/cool thermostat designed for use with electric heat
systems will meet this requirement.

The simplified connection diagram at left shows the factory
configured wiring set for 240V operation. If you are going to use
208V exclusively, switch the two (2) black wires on the 240V post
of the primary side of the transformer to the 208V post. This will
ensure correct secondary (low)voltages for the unit. This is only
required on remote thermostat units.
CAUTION
If the supply voltage is 208V, the low
voltage transformer MUST be wired for
208V operation Failure to do so will result
in lower contro_ voltages to the unit and can
damage _ow voltage components
Remote Thermostat Unit Operation
Theseunitsare controlledby the use of a remotethermostat thatwill
cycle the unitto maintaindesired room temperature.Seethermostat
operating instruction sheet for details.
The fan speed switch controlshighand low speed fan operation. Itis
located on the control panel and is independent of the thermostat.
Auto Changeover Thermostat
A singlestage heat/coolthermostatwith auto changeoveris needed.
The wiring scheme is the same as the manualthermostat.
Remote Thermostat Installation
Follow Steps 1through 5 (pages 12and 13), then:
6. Locate the terminal strip on the front of the control box (See
Figure9). Attach thethermostat subbasewires(field supplied)
to the appropriately labeled terminals in accordance with the
wiring diagram on the side of the chassis.
7. Carefullyroute the wiresalongside the conduitor service cord.

AppendixB: ElectricalWiringfor 265 Volt Models
NOTE: It is recommended that the PXSB subbase assembly, the PXCJ conduit kit and the PXDS disconnect switch be installed on all
hardwired units. If installing a flush-floor mounted unit, make provisions for allthe linevoltage power leads and conduit to be removed for
ease of maintenance and service to the chassis.
Toinstall the line voltage power leads and conduit to the chassis, follow the instructions below.
1. Remove the four control box retaining screws (A) and open
the control box.
2. Punthe chassis power lead wires (B) (locatedon the bottom-
right side of the control box) through the plastic bushing so
they are located inside the control box.
3. Remove the plastic bushing.
4. Route the line voltage power leads through the hole where
the plastic bushing was located, and secure itsconduit (use a
1/2" straightconduit connector,with the Iocknut on the inside
of the control box.)
5. Makethe appropriate electrical connections within the control
box,then secure the box onthe chassis. Detailed instructions
are included with the installation instructions for the conduit
kit (PXCJ).
6. Route the line voltage power conduit from the control
box straight down the right front to the bottom side of the
chassis. This will allow the front cover to be installedwithout
interference with the electrical conduit.

J.RoutineMaintenance
NOTE: Units are to be inspected and serviced by qualified service personnel only.
1. Clean the unit air intakefilter at leastevery 300 to 350 hours
of operation. Clean the filters with a mild detergent in warm
water and allow to dry thoroughly before reinstalling.
2. The indoor coil (evaporatorcoil), the outdoor coil (condenser
coil) and base pan should be inspectedperiodically (yearly
or bi-yearly) and cleaned of all debris (lint, dirt, leaves, paper,
etc.). Clean the coils and base pan with a soft brush and
compressed air or vacuum. If using a pressure washer, be
careful not to bend the aluminium fin pack. Use a sweeping
up and down motion in the direction of the vertical aluminum
fin pack when pressure cleaning coils. Cover all electrical
componentsto protectthem fromwateror spray. Allow the unit
to dry thoroughly, inspect allgasket materialfor deterioration
(replace as necessary), and then reinstall the chassis in the
sleeve.
NOTE: Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser.
Before reinstalling the chassis in the sleeve, inspect the
indoorblower housing, blower wheel, condenser fan blade,
and condenser shroud periodically (yearly or bi-yeafly) and
clean of all debris (lint, dirt, mold, fungus, etc.) Clean the
blower housing area and blower wheel with an antibacterial /
antifungal cleaner. Use a biodegradable cleaning agent and
degreaser on condenser fan and condenser shroud. Use
warm or cold water when rinsing these items.Allow all items
to dry thoroughly before reinstallingthem.
3. Periodically (at leastyearly or bi-yearly): inspectall control
components, both electrical and mechanical, as well as the
power supply. Use proper testing instruments(voltmeter,
ohmmeter, ammeter, wattmeter, etc.) to perform electrical
tests. Usean air conditioning or refrigeration thermometer to
check room, outdoor and coil operating temperatures. Use a
sling psychrometerto measurewet bulbtemperatures indoors
and outdoors.

K. BasicTroubleshootingTechniques
Beingfamiliarwith the sequence of operation on Standard Controlled Operating Units or the operation of the RemoteThermostat Controlled
Units is important, The following questions and answers may help to identify performance problems,
EnvironmentalEffects- CoolingMode
Is unit sized to room size area and heat load demand?
RoomWidthx Lengthx 3.5 (x-factor)equal a "guesstimate" ofthe
numberofBTU'srequiredfor the area. The numberofpeopleinthe
room, number of electrical devices, solar gains, etc. are allvariable
items thatcan affect propersizingof the unit. Friedrichrecommends
that you consult with an applications engineer for proper sizing.
Is the outdoor temperature 60°F or below?
The unit is designed for outdoor temperatures above 60°E
Is the indoor temperature 80°F or 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 indoor humidity high?
This condition will cause the unit to operate longer to remove
humidity before noticing any cooling effect.
Hasthe heat load been increased by additional devices such
as computer equipment, or hasthe room area 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
Is unit properly sized to room area and heat load demand?
Multiplying the Width x Length x 3.5 ("x-factor") provides a
"guesstimate" of the number of BTU's required for the area. The
number of people inthe room, number of electrical devices, solar
gains,etc. are all variable itemsthat can affect propersizingof the
unit. Ffieddchrecommends that you consult with an applications
engineer for proper sizing.
Is the outdoortemperature 70oForabove?- The unit is designed
for outdoor temperatures below 70°E
Is the indoor temperature 60°F or below? Ambient indoor
temperatures of 6O°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.
Hasthe room area been increased where the unit is located?
If the area where the unit is located has been increased, the unit
may not provideadequateheat.
