Control Panel Operation Instructions

SYSTEM - The MODE button allows you to sequentially select up to four modes of operation:

AUTO Available on select models

COOL

HEAT Available on select models

FAN ONLY

AUTO FAN (No Cooling Demand)

When in AUTO mode, the fan only operates when the system has a demand to cool or heat the room.

In the ON fan mode, the fan operates all the time. The system periodically

cools or heats the fan’s airow but the ow of air does not stop.

UP and DOWN Arrows - Pressing either an UP or DOWN button changes the system’s setpoint (desired room temperature). These buttons are also used to make system parameter changes later in this manual.

One press equals 1 degree of change in Fahrenheit mode. One press equals 0.5 degree change in Celsius mode.

TIMER

The timer can be engaged or disengaged from the control panel. This is done by pressing or holding the UP and DOWN arrows simultaneously for three seconds.

Alerts

When the lter needs to be cleaned or replaced, the CHECK FILTER icon displays.

The alert can be dismissed by holding the FAN and SPEED for 3 seconds.

Lock Control Panel

To lock/ unlock the front panel controls, navigate to the “LOCK” sub-menu found after clicking the MENU button. The lock requires a four digit pass code to lock/ unlock the unit. This pass code will be required to enter the menu to unlock the unit. The LOCK icon illuminates to indicate the locked status.

The LOCK icon disappears to indicate unlocked status.

External Control Status

The Wi-Fi icon illuminates to indicate that the system is receiving a Wi-Fi connection. The Wi-Fi icon also provides information about the signal strength.

ADVANCED FUNCTIONS

The functions mentioned in the following section may or may not be available depending on the air conditioner model.

Modify the TIMER Function

Navigate to the TIME menu to set the timer.

OTHER FUNCTIONS

°F – °C Select

To switch from degrees Fahrenheit (F) to Celsius (C), press the MENU button and enter the F-C sub-menu.

Page 25

Remote Control Operation

Remote Control - Refer to Figure 52 during operation description.

Getting Started - Install two (2) AAA batteries in the battery compartment

located on the back of the unit.

Operation - The remote control should be within 25 feet of the air conditioner for operation (refer to Figure 52 for effectiveness). Press the power button to turn the remote on. The remote will automatically power off after 15 seconds if the buttons are not being pressed. The remote must be on to control the unit.

POWER Button - Turns remote and unit on and off.

SYSTEM Button - Allows the user to sequentially select the following: AUTO, COOL, HEAT, and FAN ONLY operations. When the button is

pressed, the display indicates which mode has been selected via a display message. Note that when the heating function is not available, the system will automatically skip the HEAT mode.

FAN MODE Button - Selects between automatic (AUTO FAN) or CONTINUOUS operation. In the AUTO FAN mode, the fan only turns on

and off when the compressor operates or the heat function is enabled.

NOTE: AUTO FAN is not available in the FAN ONLY Mode, the display

indicates CONTINUOUS. In the CONTINUOUS mode, fan speed is determined by your selection on the FAN SPEED button.

FAN SPEED Button - Used to sequentially select new fan speed, plus AUTO operation. When the FAN SPEED button is pressed, the fan speed icon (triangle) changes to indicate the new speed level. Fan speed automatically varies depending on the set temperature on the

control panel and the actual room temperature. For example, if there

is a big difference between your set temperature and the actual room temperature, the system fan speed increases to HIGH. It remains at this speed until the room temperature matches the set temperature.

UP and DOWN Arrows - Pressing either the UP or DOWN button changes the desired room temperature. The factory preset lower and upper limits are 60 °F (16 °C) and 99 °F (37 °C). These buttons are also used to navigate between function options when using the User Menu or Maintenance Mode.

Remote Effectiveness

Handheld Remote - Has an operating range of up to 25 ft. The infrared remote control signal must have a clear path to transmit the command to the air conditioning unit. The remote signal has some ability to “bounce” off of walls and furniture similar to a television remote control. The diagram below shows the typical operating range of the control in a standard room with 8 ft high ceilings.

Airflow Selection and Adjustment

Airflow direction adjustment

The airow path may be adjusted to distribute air independently from the

left or right side of the discharge opening. Each of the banks of louvers can be directed left, right, up, or down in order to achieve the most optimum

airow positioning.

To adjust airow direction, grab the lever in the center of the louver bank

and move it in the direction that you would like the air to be directed. Please

note that it is normal that airow may be stronger out of one side of the

louvers than the other.

Figure 53

Fresh air and exhaust control

Your air conditioner has the ability to bring fresh air into the room or exhaust

stale air out of the room. The control slide is found on the upper part of the unit (see Figure 53).

TO BRING IN FRESH AIR – Move the lever to the Fresh Air position which allows outside air to enter the room. This is useful in fall and spring

as a means of bringing in fresh outside air when using FAN ONLY. It can

also be used in the summer with the compressor in the Cooling Mode if you wish.

TO EXHAUST INDOOR AIR – Move the lever to the Exhaust position.

This will allow stale air to be expelled to the outside of the dwelling. This

is especially handy in the spring or fall when indoor air tends to get stale, or after a social gathering involving smokers, or to remove cooking odors.

BEST PERFORMANCE – Move the lever to the Re-Circulate Position.

This is the most efcient mode for cooling and heating.

Installation Instructions

READ THIS FIRST! Electrical Requirements

WARNING

Electrical Shock Hazard

Make sure your electrical receptacle has the

same conguration 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 outlet. Failure to follow these instructions can result

in death, re, or electrical shock.

IMPORTANT: Before you begin the actual installation of your air conditioner, check your local electrical codes and the information below.

Your air conditioner must be connected to a power source with the same

alternating current (A.C.) voltage and amperage as marked on the name plate located on the chassis. Only A.C. can be used. Direct Current (D.C.) cannot be used.

CIRCUIT PROTECTION – Use on single outlet circuit only. An overloaded circuit will invariably cause malfunction or failure of an air conditioner; therefore, it is necessary that the electrical protection is adequate. Due to momentary high current demand when the air conditioner starts, use a

“TIME DELAY” fuse or a HACR type circuit breaker. Consult your dealer or

power company if in doubt.

Refer to the electrical name plate located on the air conditioner chassis (see Page 2) to determine the correct fuse or circuit breaker amperage for your model (see Table 1 on Page 6 for electrical receptacle types).

The power cord has a plug with a grounding prong and a matching receptacle is required.

The following instructions are for standard chassis model groups

distinguished by the rst three letters of the model designations cabinet

sizes listed in Table 2.

Final Inspection & Start-up Checklist

♦ Inspect and ensure that all components and accessories have been

installed properly and that they have not been damaged during the installation progress.

♦ Check the condensate water drain(s) to ensure that they are

adequate for the removal of condensate water, and that they meet the approval of the end user.

♦ Ensure that all installation instructions concerning clearances around

the unit have been adhered to. Check to ensure that the unit air lter,

indoor coil, and outdoor coil are free from any obstructions.

♦ Ensure that the circuit breaker(s) or fuse(s) and supply circuit wire

size have been sized correctly. If the unit was supplied with a power supply cord, insure that it is stored properly.

♦ Ensure that the entire installation is in compliance with all applicable

national and local codes and ordinances having jurisdiction.

♦ Secure components and accessories, such as a decorative front cover. ♦ Start the unit and check for proper operation of all components in

each mode of operation.

♦ Instruct the owner or operator of the units operation, and the

manufacturer’s Routine Maintenance.

NOTE: A log for recording the dates of maintenance and/ or service is

recommended.

♦ Present the owner or operator of the equipment with the Installation &

Operation Manual, all accessory installation instructions, and the name, address, and telephone number of the Authorized Friedrich Warranty Service Company in the area for future reference if necessary.

Heat pumps operate differently

If your unit is a “KH”, or heat pump model, there are some things that you will want to be aware of. Some functions of a heat pump differ from your unit when it is used for heating:

1. It is normal for ice to form on the outdoor coil of the heat pump. Moisture in the outside air, passing over the coil when very cold, will form ice.

2. If the outdoor temperature drops below 37 °F (3 °C), your heat pump will automatically turn on the electric resistance heat. When the temperature rises to 40 °F (4 °C), the compressor will resume the heat pump operation. If your unit is a 115 volt model (KHS10), it is designed for use in warmer climates and does not have an electrical heat feature, and will not provide adequate heat below 37 °F (2.8 °C).

Control Panel Battery Change Procedure

Remove the grille, by loosening four (4) captive screws (see Figure 84). In the upper left corner, remove one (1) screw on the battery retaining door (see Figure 85). Remove and replace the battery (CR2450). Reinstall the battery retaining door. Align the grille guide pins then tighten the four

(4) captive screws. Before closing the grille panel door, check the lter.

Clean or replace it as necessary.

Figure 84

This is a warm weather appliance

Your air conditioner is designed to cool in warm weather when the outside

temperature is above 60 °F (15.6 °C) and below 115 °F (46.1 °C), so it won’t cool a room if it is already cool outside. If you want to cool a room in the spring or fall, select the FAN ONLY mode and set the Fresh Air/ Exhaust air control to Fresh Air. This will bring in a supply of cooler outside air.

Condensation is normal

Air conditioners actually pump the heat and humidity from your room to the outside. Humidity becomes water, and your air conditioner will use most of

the water to keep the outside coil cool. If there is excessive humidity, there may be excess water that will drip outside. This is normal operation.

Frosting

This usually occurs because of insufcient airow across the coils, a dirty lter, cool damp weather, or all these. Set the SYSTEM mode to FAN

ONLY and the frost will disappear. Setting the thermostat a little warmer will probably prevent the frosting from recurring.

Noises

All air conditioners make some noise. Friedrich units are designed to operate as quietly as possible. An air conditioner mounted in a wall is quieter than one mounted in a window. It is important to ensure that the chassis seal gasket (Item 13) is properly installed (refer to the Installation Instructions).

Routine Maintenance Service and Assistance

To ensure proper unit operation, the air lter should be cleaned at least

monthly, and more frequently if conditions warrant. The unit must be turned

off before the lter is cleaned.

To Remove, Wash and Replace Filter

Lower front panel (Figure 2). Use the handle on the lter to ex lter up and out of retainer. Remove lter from unit (Figure 3). Clean the lter monthly or more frequently if needed. Refer to the Accessories section for lter options.

Coils & Chassis

NOTE: Do not use a caustic cleaning agent on coils or base pan. Use a

biodegradable cleaning agent and degreaser. The use of harsh cleaning materials may lead to deterioration of the aluminum

ns or the coil end plates.

The indoor coil and outdoor coils and base pan should be inspected periodically (annually or semi-annually) and cleaned of all debris (lint,

dirt, leaves, paper, etc.) as necessary. Under extreme conditions, more

frequent cleaning may be required. Clean the coils and base pan with a soft brush and compressed air or vacuum. A pressure washer may also be

used; however, you must be careful not to bend the aluminum n pack. Use a sweeping up and down motion in the direction of the vertical aluminum n

pack when pressure cleaning coils.

NOTE: It is extremely important to insure that none of the electrical

and/ or electronic parts of the unit get wet. Be sure to cover all electrical components to protect them from water or spray.

Decorative Front

Use a damp (not wet) cloth when cleaning the control area to prevent water from entering the unit, and possibly damaging the electronic control.

The decorative front and the cabinet can be cleaned with warm water and a mild liquid detergent. Do NOT use solvents or hydrocarbon based cleaners such as acetone, naphtha, gasoline, benzene, etc.

The indoor coil can be vacuumed with a dusting attachment if it appears to be dirty. DO NOT BEND FINS. The outdoor coil can be gently sprayed with a hose if you can get to it. If not, you might call your dealer for a more thorough cleaning when needed.

The air lter should be inspected weekly and cleaned if needed by

vacuuming with a dust attachment or by cleaning in the sink using warm

water and a mild dishwashing detergent. Dry the lter thoroughly before

reinstalling. Use caution, the coil surface can be sharp.

Fan Motor & Compressor

The fan motor & compressor are permanently lubricated and require no additional lubrication.

Wall Sleeve

Inspect the inside of the wall sleeve and drain system periodically (annually

or semi-annually) and clean as required. Under extreme conditions, more

frequent cleaning may be necessary. Clean both of these areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as needed.

COMPLAINT CAUSE SOLUTION

• The outside temperature is below 60 °F

(16 °C).

• The digital control is set to fan cycling mode.

Unit Does Not Cool/ Heat Room

Sufciently, or Cycles On And Off

Too Frequently (continued).

Unit Runs Too Much.

• The air conditioner has insufcient cooling

capacity to match the heat gain of the room.

• The air conditioner has insufcient heating

capacity to match the heat loss of the room.

• This may be due to an excessive heat load

in the room.

• It may also be due to an improperly sized unit.

• This may be normal for higher efciency

(EER) air conditioners.

• You may notice that the discharge air

temperature of your new air conditioner may not seem as cold as you may be accustomed to from older units. This does not; however, indicate a reduction in the cooling capacity of the unit.

• Do not try to operate your air conditioner in the

cooling mode when the outside temperature is below 60 °F (16 °C). The unit will not cool properly, and the unit may be damaged.

• Since the fan does not circulate the room air

continuously at this setting, the room air does not

mix as well and hot (or cold) spots may result. Using

the continuous fan setting is recommended to obtain optimum comfort levels.

• Check the cooling capacity of your unit to ensure it

is properly sized for the room in which it is installed. Room air conditioners are not designed to cool multiple rooms.

• Check the heating capacity of your unit. Air conditioners

are sized to meet the cooling load, and heater size

is then selected to meet the heating load. In extreme

northern climates, room air conditioners may not be able to be used as a primary source of heat.

• If there are heat producing appliances in use in the

room, or if the room is heavily occupied, the unit will need to run longer to remove the additional heat.

• Be sure to use exhaust vent fans while cooking or

bathing and, if possible, try not to use heat producing appliances during the hottest part of the day.

• The use of higher efciency components in your new

air conditioner may result in the unit running longer than you feel it should. This may be more apparent, if

it replaced an older, less efcient, model. The actual energy usage, however, will be signicantly less

when compared to older models.

• The energy efciency ratio (EER) and cooling

capacity rating (Btu/ h) listed on the unit’s rating

plate are both agency certied.
