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 beused.

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 mustbe 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 atansites where condensate or external

water could potentially infiltrate intothe building.

6. Condensate notches and overflow slots must be kept clear
ofsealant and gaskets so condensate canflow freely intothe

wall sleeve extension.

NOTE: Improperfabricationor installationofa wallsleeveextension

will impair PTAC performance.

Extension Installation

Secure thewall sleeveextensionto the wail sleeve beforeinstalling
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 carein 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 notuse 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 ifthe heatingdemand cannot bemet by the
heat pumpdue to low outdoor temperatures.

Manual Changeover Thermostat

For Heat Pump equipped units: A single stage, heat/cool

thermostatwith aterminalfora reversingvalve operationisrequired.
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:

Y Cooling During call for cooling.

W Heating During call forheating.

G Fan Continuous if the slider is inthe "Fan" position,otherwise, intermittent.
C Common Terminal Forthermostats 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

NOTE: Itis recommended that the PXSBsubbase 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 linevoltage 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. Punthechassis 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
theplastic bushing was located,and secure itsconduit (use a
1/2" straightconduit connector,with the Iocknuton the inside
ofthe control box.)

5. Makethe appropriateelectricalconnections within thecontrol
box,thensecure the boxonthechassis. 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 allowthe 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 unitair intakefilter at leastevery 300 to 350 hours
of operation. Clean the filters with a mild detergent in warm

water and allowto 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 ofall 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

componentstoprotectthem fromwateror spray. Allow theunit
todry 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 housingarea and blowerwheel 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 allitems

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 operatingtemperatures. Use a
slingpsychrometertomeasurewet bulbtemperatures indoors

K.BasicTroubleshootingTechniques

Beingfamiliarwith the sequence ofoperation on StandardControlled OperatingUnitsor theoperationof the RemoteThermostat Controlled
Unitsis 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
itemsthatcan affect propersizingoftheunit. Friedrichrecommends

that you consultwith an applications engineer for proper sizing.
Is the outdoor temperature 60°F or below?

The unitis designed for outdoor temperatures above60°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 isundersized.
Is indoor humidity high?

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

Hasthe heat loadbeen increased byadditional devices such

as computer equipment, or hasthe room areabeen 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 ofelectrical devices, solar

gains,etc. are all variable itemsthat can affect propersizingofthe
unit. Ffieddchrecommends that you consult with an applications

engineer for propersizing.
Is the outdoortemperature 70oForabove?- Theunit isdesigned

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 roomarea been increased where the unit is located?

If the area where the unit is located has been increased, the unit

may not provideadequateheat.

Insufficient Maintenance and Inspection
