Safety Precautions

We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages.

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

Your safety and the safety of others are very important.

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

WARNING CAUTION

Indicates a hazard which, if not avoided, can result in severe personal injury or death and damage to product or other property.

Indicates a hazard which, if not avoided, can result in personal injury and damage to product or other property.

NOTICE

Indicates property damage can occur if instructions are not followed.

WARNING

Refrigeration system

under high pressure

Do not puncture, heat, expose to flame or incinerate.

Only certified refrigeration technicians should service this equipment.

R410A systems operate at higher pressures than R22 equipment. Appropriate safe service and handling practices must be used.

Only use gauge sets designed for use with R410A. Do not use standard R22 gauge sets.

Unpacking Instructions

STEP 5. Slide the foam front support forward STEP 1. Cut all 4 packing straps. STEP 2. Remove wooden shipping bar dividers. STEP 3. Remove top foam pads. STEP 4. Slowly remove outer box, careful not to loosen decorative front.

STEP 6. Carefully lift decorative front box from foam front support

STEP 7. Remove decorative front and set safely aside

WARNING

NOTICE

Electrical Shock Hazard

Make sure your electrical receptacle has the same configuration as your air conditioner’s plug. If different, consult a Licensed Electrician.

Do not use plug adapters. Do not use an extension cord. Do not remove ground prong.

Always plug into a grounded 3 prong oulet. Failure to follow these instructions can result in death, fire, or electrical shock.

Make sure the wiring is adequate for your unit.

If you have fuses, they should be of the time delay type. Before you install or relocate this unit, be sure that the amperage rating of the circuit breaker or time delay fuse does not exceed the amp rating listed in Table 1.

DO NOT use an extension cord.

The cord provided will carry the proper amount of electrical power to the unit; an extension cord may not.

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

Proper grounding must be maintained at all times. Two prong receptacles The grounded receptacle should meet all national and local codes and

ordinances. You must use the three prong plug furnished with the air conditioner. Under no circumstances should you remove the ground prong from the plug.

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 on the end of the cord meets the UL and NEC requirements for c

ord 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 1).

3. Press TEST, listen for click; the RESET button trips and pops out.

4. Press and release RESET (Listen for click; RESET button latches

and remains in). The power cord is ready for use.

Do not use the LCDI device as an ON/OFF switch.

Failure to adhere to this precaution may cause premature equipment malfunction.

Once plugged in, the unit will operate normally without the need to reset the LCDI device. If the LCDI device fails to trip when tested or if the power supply cord is damaged, it must be replaced with a new power supply cord from the manufacturer. Contact our Technical Assistance Line at (800) 541-6645. To expedite service, please have your model number available.

New Kühl Control Options

The new Kühl gives you a variety of options for control, programming, and scheduling including wireless capabilities

Wireless Programming and Control:

. The new FriedrichLink™ Adapter (sold seperately) allows you to conviently

control, program and monitor your air conditioning unit remotely from a

smartphone or computer. FriedrichLink™ Adapter accessory available through Friedrich authorized

retailers or www.friedrich.com. See FriedrichLink™ Adapter section on www.friedrich.com for complete details.

Pre-Programmed Scheduling Options:

Your unit’s digital control comes equipped with a 24-hour timer and two preprogrammed 7-day energy management options.

24-Hour Timer The 24-hour timer allows you to turn the unit off and on at pre-set times by

setting an on and off time on the unit control panel. (See page 12 for details on timer set-up.)

Pre-programmed Energy Management Your unit comes from the factory with two (2) Pre-programme

Management settings are shown in Addendum 1 (Residential & Commercial Schedule Table).

Energy Management Schedule Options are:

1. Residential Schedule – 40 Hr. Work Week

2. Commercial Schedule – 5-Day Business Week

Energy

The “Residential” (40 Hr. Work Week) Schedule has four (4) time periods: 06:00, 08:00, 18:00, and 22:00. This option will cause your Kühl Q unit to raise the room temperature temporarily to 85°F during the hours wh

en most people are away at work, lower them again to 78°F prior to the time when most people will return home, and then raise slightly to 82°F to maintain a comfortable temperature overnight.

The “Commercial” (5-Day Business Week) Schedule has two (2) time periods: 07:00 and 18:00. This option will cause your air conditioner to raise temperatures to 84°F after typical working hours and on weekends when commercial spaces ar

typically unoccupied.

(See Control Panel Operation Instructions Section)

Customizable Programming Options:

Customizable schedules, with up to four temperature adjustments per day, can

either be uploaded to the unit via the air conditioner’s built-in micro USB interface or conveniently transmitted wirelessly using the new FriedrichLink™ Adapter accessory, greatly simplifying the programming of one or multiple units. See Figure 9.
