ELECTRICAL DATA

Not following the above WARNING could result in re or electically unsafe conditions which could cause moderate or serious property damage.

Read, understand and follow the above warning.

WARNING

ELECTRIC SHOCK HAZARD

Turn off electric power before service or installation.

All electrical connections and wiring MUST be installed by a qualied electrician and conform to the National Electrical Code and all local codes which have jurisdiction.

Failure to do so can result in personal injury or death.

NOTICE

FIRE HAZARD

Wire Size Use ONLY wiring size recommended for single outlet branch circuit.

Fuse/Circuit Breaker Use ONLY the correct HACR type and size fuse/circuit breaker. Read electrical ratings on unit’s

rating plate. Proper circuit protection is the responsibiity of the homeowner.

Grounding Unit MUST be grounded from branch circuit through service cord to unit, or through separate

ground wire provided on permanently connected units. Be sure that branch circuit or general purpose outlet is grounded.

Receptacle The eld supplied outlet must match plug on service cord and be within reach of service cord.

Do NOT alter the service cord or plug. Do NOT use an extension cord. Refer to the table above for proper receptacle and fuse type.

The consumer - through the AHAM Room Air Conditioner Certication Program - can be certain that the AHAM Certication Seal accurately states the unit’s cooling and heating capacity rating, the amperes and the energy efciency ratio.

*HACR: Heating Air Conditioning and Refrigeration

Keep the filter clean

Make sure that your air conditioner is always in top performing condition

.ylralugerretlifehtgninaelcyb

Provide good air flow

Make sure the airflow to and from the unit is clear. Your air conditioner puts the conditioned air out at the top of the unit, and takes in unconditioned air at the bottom. Airflow is critical to good operation. It is just as important on the outside

.dekcolbtonsiroiretxetinuehtdnuorawolfriaehttahtgnidliubehtfo

Unit placement

If your air conditioner can be placed in a window or wall that is shaded by a tree

rosepardgnisU.yltneiciffeeromneveetarepolliwtinueht,gnidliubre hto naro

blinds on the sunny side of the dwelling will also add to your unit’s efficiency.

Insulation

Good insulation will be a big help in maintaining desirable comfort levels.

Doors should have weather stripping. Be sure to caulk around doors and

windows.

Proper installation of seal gasket

Make sure the seal gasket has been installed properly to minimize noise and improve efﬁ ciency. If the seal gasket has not been installed, please refer to Step 14 of the

installation instructions.

Also, if you switch from Cool mode to Fan Only, and switch back to COOL mode, there is a three minute delay before the compressor comes

back on.

For the best cooling performance and highest energy efficiency

WARNING: Before operating your unit

Make sure the wiring is adequate for your unit.

If you have fuses, they should be of the time delay type. Before you install

rekaerbtiucricehtfognitaregarepmaehttahteruseb,tinusihtetac olerro

or time delay fuse does not exceed the amp rating listed in Figure 1.

DO NOT use an extension cord.

The cord provided will carry the proper amount of electrical power to the

.tonlliwdrocnois netxena;tinu

Make sure that the receptacle is compatible with the air conditioner cord plug provided.

This insures proper grounding. If you have a two prong receptacle you will need to have it replaced with a grounded receptacle by a certiﬁ ed electrician. The grounded receptacle should meet all national and local codes and ordinances. Under no circumstances should you remove the ground prong from the plug. You must use the three prong plug furnished with the air conditioner.

Test the power cord

All Friedrich room air conditioners are shipped from the factory with a Leakage Current Detection Interrupter (LCDI) equipped power cord. The LCDI device meets the UL and NEC requirements for cord connected air conditioners.

To test your power supply cord:

1. Plug power supply cord into a grounded 3 prong outlet.

2. Press RESET (See Figure 2).

3. Press TEST (listen for click; Reset button trips and pops out).

4. Press and release RESET (listen for click; Reset button latches and remains in). The power supply cord is ready for operation.

NOTE: LCDI d

evice is not intended to be used as a switch.

Once plugged in the unit will operate normally without the need to reset the LCDI device.

If the device fails to trip when tested or if the power supply cord is damaged it must be replaced with a new supply cord from the manufacturer. We recommend you contact our Technical Assistance Line at (800) 541-6645 ext. 845. To expedite service, please have your model and serial number available.

TESTING THE ELECTRONIC CONTROL ERROR CODE LISTINGS

E1 SHORT CYCLE SITUATION: Dened as (compressor

powered on before the three minute time delay ten times in one hour. Investigate and correct short cycling problem.

E2 KEYBOARD STUCK ERROR: If key button(s) are pressed continuously for twenty seconds or more. If MODE key is stuck, unit will default to cool. Exit Error Code Mode to see if error “E2” is no longer displayed and unit is functioning. Replace board if “E2” still displays after exiting

Error Code Mode.

E6 INDOOR PROBE SHORT: Control assumes

ambient temperature is 90 degree F and unit will operate. Replace probe.

NOTE: All Error Code displays for Frost & Indoor Probe will allow unit to operate. Unit may or will ice up if faulty components not replaced.

FROST PROBE SENSOR: disables compressor at 35 degrees F.

INDOOR PROBE SENSOR: Control range is 60 degrees F to 90 degrees F +/- 2 degrees F.

Indoor temperature will be displayed by pressing: (QME units) The Fan Speed button and the Temperature button.

(XQ units) The Fan Speed button and the “TEMP “

button.

The indoor temperature will be displayed for 10 seconds. The display will change back to the Set Point temperature by pressing any key button except for the On/Off button. The indoor temperature can be viewed in all modes, including test mode.

Check Filter: The Check Filter indicator turns on after the fan motor has been operating for 250 hours. The

Check Filter indicator is reset by pressing the Check Filter button one time only. Power failures will not reset

the 250 hour timer. All time elapsed is stored in memory and resumes counting after power is restored.

Keep Alive: The electronic control has a memory to retain all functions and status as set up by the user in the event of a power failure. Once power is restored to the unit there is a two second delay before the fan comes on and approximately three minutes delay before the compressor is activated, providing that the mode was set for cooling and the set point temperature has not been met in the room.

E3 FROST PROBE OPEN: Normal operation is allowed. Ohm frost probe. Replace probe if ohm value not read. If ohm value is present replace board.

E4 FROST PROBE SHORT: Normal operation allowed. Replace probe.

E5 INDOOR PROBE OPEN: Control assumes indoor ambient temperature is 90 degree F and unit will operate. Ohm indoor probe. Replace probe if ohm value not read.
