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.

Remote Control - Refer to Figure 47 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 47 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

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

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 5 for electrical receptacle types).

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

WARNING

MOVING PARTS HAZARDS

• Do not operate unit out of sleeve or

with front grille removed.

• Do not place hands in blower or fan

blade areas.

Failure to do so can result in serious injury.

CAUTION

Excessive Weight Hazard

Use two or more people when installing your air conditioner.

Failure to do so can result in back or other injury.

Installation Instructions for WSE Sleeve continued

Installation Requirements

STEP 1. The WSE sleeve should be positioned so that the drain

extension extends a minimum of 9/16″ beyond the outside wall

(see Figure 48).

STEP 2. The WSE sleeve must extend a minimum of 7/8″ beyond the

inside wall.

STEP 3. The WSE sleeve must be installed level side to side.

STEP 4. The WSE sleeve must also be installed with a downward tilt

toward the outside of the building. If a level is placed so that it rests on the front and back unit rest as shown in Figure 49, a properly installed unit provides a 3/8″ slope to the outside of the building.

NOTICE

Sleeve projections and leveling precautions must be observed to prevent the entry of water into the room.

Figure 49

Sleeve Requirements

STEP 1. After unpacking the WSE sleeve from the carton, remove the

indoor weather panel. Place the WSE sleeve in the wall opening following the instructions given in the Installation Requirements.

Attach the sleeve to the inside wall by driving two #12A x 2″

screws in each side of the sleeve (see Figure 50). Shim at the top of the sleeve, midway between the sides. Drive one #12A

x 2″ screw in the top of the sleeve. If the wall opening is not framed with wood, use expansion anchor bolts or molly (toggle)

bolts (not provided).

STEP 2. Once the sleeve has been installed, check the level again to be

sure the 3/8″ downward slope is maintained.

NOTE: If necessary, apply shims below the chassis and inside

the sleeve front unit rest, to ensure a 3/8″ downward slope front to back.

STEP 3. Caulk the perimeter of the entire opening on the inside and the

outside between the sleeve and the wall.

STEP 4. The indoor weather panel removed in Step 1 above must be

remounted back in place if masonry work is to be done and/ or if the “WallMaster”chassis is to be installed at a later date.

How to cover inner weather panel holes

Two beige plugs are included in the plastic bag taped to the WallMaster chassis. These plugs may be used to cover the two holes left after removing the indoor weather panel.

DRAIN HOSE

DK (Drain Kit)

In the event that the outdoor temperature drops below 37 °F, any water that remains in the chassis basepan is drained into the sleeve pan on WET and WHT models to prevent freezing. (NOTE: In the cooling

mode of the WCT, WET and WHT models, condensate overow is

possible in very humid climates). For these particular instances, an optional drain kit (Accessory #DK) is available for water removal.

IDK (Drain Kit)

New construction allowing for condensate drain systems built within the walls can use the Friedrich Interior Drain Kit (Accessory #IDK). This kit is designed for installation in the bottom of the sleeve below the condensate bellows valve (heat/ cool models only).

Troubleshooting Tips continued

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.
