— NOTES —

1-1

Electrical Shock Hazard

Plug into a grounded 3-prong outlet.

Do not remove ground prong.

Do not use an adapter.

Do not use an extension cord.

Failure to follow these instructions canresult in death, fire, or electrical shock.


Disconnect power before servicing.

Replace all panels before operating.

Failure to do so can result in death orelectrical shock.

GENERALSAFETY FIRST

Your safety and the safety of others is very important.

We have provided many important safety messages in this Job Aid and on the appliance. Alwaysread and obey all safety messages.

This is the safety alert symbol.This symbol alerts you to hazards that can kill or hurt you and others.All safety messages will follow the safety alert symbol and either the word“DANGER” or “WARNING.” These words mean:

All safety messages will tell you what the potential hazard is, tell you how to reduce the chanceof injury, and tell you what can happen if the instructions are not followed.

You can be killed or seriously injured if you don’timmediately follow instructions.

You can be killed or seriously injured if you don’tfollow instructions.

ELECTROSTATIC DISCHARGE(ESD) SENSITIVE ELECTRONICS

ESD problems are present everywhere. ESDmay damage or weaken the electronic controlassembly. The new control assembly may ap-pear to work well after repair is finished, butfailure may occur at a later date due to ESDstress.

• Use an antistatic wrist strap. Connect thewrist strap to a green ground connectionpoint or unpainted metal in the appliance; ortouch your finger repeatedly to a green groundconnection point or unpainted metal in theappliance.

• Before removing the part from its package,touch the antistatic bag to a green groundconnection point or unpainted metal in theappliance.

• Avoid touching electronic parts or terminalcontacts. Handle the electronic control as-sembly by the edges only.

• When repackaging the failed electronic con-trol assembly in an antistatic bag, observethe above instructions.


Connect green ground wire to groundscrew.


Excessive Weight Hazard

Use two or more people to move andinstall the air conditioner.

Failure to do so can result in back, orother injury.

IMPORTANT NOTES:

• Make sure that you maintain a good gripon the air conditioner so that it does notfall out of the window opening during theinstallation.

• Make sure that you center the unit in thewindow so that the L-brackets mate withthe bottom guides. If the unit is not cen-tered properly, it could slide out of theopening.

3. Carefully lift the air conditioner, and centerit in the window opening, then slide it intoplace so that the bottom guides drop intothe two L-brackets you installed in step 2.

1. Open the window and mark the centerlineof the inner sill.

COMPONENT TESTINGBefore testing any of the components, performthe following checks:

• The most common cause for control failure iscorrosion on connectors. Therefore, discon-necting and reconnecting wires will be nec-essary throughout test procedures.

• All tests/checks should be made with a VOMor DVM having a sensitivity of 20,000 ohms-per-volt DC, or greater.

• Check all connections before replacing com-ponents, looking for broken or loose wires,failed terminals, or wires not pressed intoconnectors far enough.

• Resistance checks must be made with powercord unplugged from outlet, and with wiringharness or connectors disconnected.

Thermistor ConnectorTest @ Pins 1 & 2

Refer to page 3-6 for the procedure for servic-ing the thermistor.


2. Disconnect the thermistor 4-wire connec-tor at CN-TH1.
