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 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 Figure 1.

DO NOT use an extension cord.

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

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 certi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 effective August 2004.

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 device 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.

For the best cooling performance and highest energy efficiency

Keep the filter clean

Make sure that your air conditioner is always in top performing condition by cleaning the filter regularly. Instructions for removing and cleaning the filter can be found on page 7.

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 of the building that the airflow around the unit exterior is not blocked.

Unit placement

If your air conditioner can be placed in a window or wall that is shaded by a tree or another building, the unit will operate even more efficiently. Using drapes or 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 efciency. If the seal gasket has not been installed, please

refer to Step 14 (page 13) 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.

How to operate your Friedrich room air conditioner

(QuietMaster 'K' & Heavy Duty models / Twintemp models)

To start unit

If your air conditioner is installed and plugged into a properly grounded receptacle, it is ready to operate.

Mode control (QuietMaster ‘K’ and Heavy Duty)

The upper dial (Figure 5) allows you to select cooling at four different speeds, as well as Fan Only (Models SL28 and SL36 only have three cooling speeds.).

Off - to turn the unit off. High Cool - for quick cooling. Medium Cool - to maintain a desired temperature. Low Cool - when cooling demand is low. Sleep Setting - for nighttime use, or when cooling demand is low. Fan Only - to circulate air in the room without the compressor coming on.

The Fan Only s et ti ng c an als o b e us ed wi th t he Exhaust air setting to remove stale air or smoke from the room; or it can be used with the Fresh Air setting

to bring outside air into the room. This is especially useful in the spring and fall when cooling may not be necessary. The Fresh Air and Exhaust controls

are in the upper air discharge area. The center position of this control is the

normal, or closed position, which recirculates air for maximum performance in the cooling mode (See Figure 9).

Mode control (Twintemp)

This dial allows you to select cooling or heating at three different speeds, as well as Fan Only (Figure 6).

Off - to turn the unit off. High Cool or High Heat - for quick response. Medium Cool or Medium Heat - to maintain a desired temperature. Low Cool or Low Heat - for nighttime use, or when demand is low. Fan Only - to circulate air in the room without the compressor coming on.

The Fan Only setting can also be used with the Exhaust air setting to

remove stale air or smoke from the room, or it can be used with the Fresh

Air setting to bring outside air into the room, especially in the spring and

fall when cooling isn’t necessary.

The Fresh Air and Exhaust controls are in the upper air discharge area (see Figure 9, page 7). The center position of this control is the normal, or closed position, which recirculates air for maximum performance in the cooling mode.

NOTE: You may notice an odor when rst activating the heat when the

electric heat element comes on. This is due to dust burning off that may

have gathered on the coil during the summer. This is normal.

Temperature control

The bottom dial on the control panel is the thermostat. Turn it clockwise

for cooler temperature and counterclockwise for warmer.

Money Saver® switch

This rocker switch can be depressed to either Yes o r No. In the Yes position you will get the most economical operation. Both the fan and compressor

will cycle on and off together, maintaining the selected temperature at a

more constant level and reducing the humidity more efciently in the cooling

mode. This control will only operate when the unit is in cooling or heating mode. In the No position, the fan will run constantly as long as the unit is in the cooling or heating mode.

NOTE: The YS09 is a 115 volt model and does not provide adequate heat below 37°F (3°C). This product is designed for warm climate applications.

Care and Maintenance / Fresh air and exhaust control

To remove, wash and replace filter and return air grille

Open the return air (RA) grille by grasping it at the top outside edges and pulling towards you (See Figure 7). The RA grille will stay open until it is detached or closed (it is easier to completely detach the grille before closing it). To remove the RA grille, grasp it at the bottom and pull towards you.

The lter is held in place by two spring clips (See Figure 7). Push down on the clips, grasp the lter and pull towards you to remove it for cleaning. Clean

with warm water and a mild detergent, rinse, dry completely and replace.

Use caution when removing the lter. The coil surface can be sharp.

If the RA grille has been removed, pick up the grille by supporting it from both sides near the bottom (See Figure 8, Note 1). Lift return air grille and insert the grille's tabs into the bottom slots of the discharge air plenum (See Figure 8, Note 2). Snap the grille into place by pushing the grille up and onto the unit's latches at the bottom (See Figure 8, Notes 3 and 4).

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 lever is found on the upper part of the unit (See Figure 9).

TO BRING IN FRESH AIR - Move the lever to the Fr esh A ir 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.

Normally, for most efcient operation, cooling is accomplished with this

control in the middle or closed position. TO EX HAU ST I ND OO R AI R - Mov e th e lev er t o th e 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 odors after cooking.

Installation Instructions

920-198-00

NOTE: This manual includes installation instructions for window mount and thru-the-wall mount methods. TwinTemp

heat/cool units are designed for

permanent thru-the-wall installation. Mounting the unit in a window will require a window mounting accessory kit, available through your Friedrich dealer.

Read This First! Electrical Requirements

I MP OR TAN T: Before you begin the actual installation of your air conditioner,

check local electrical codes and the information below. Your air conditioner must be connected to a power supply with the same

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

used. Refer to page 3 for the correct type of receptacle for your model.

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 your air conditioner is started, use a "TIME DELAY" fuse or a HACR type circuit breaker. Consult your dealer or power company if in doubt.

MODEL DESIGNATION CABINET SIZE (H x W x D)

SMALL CHASSIS - SS, ES, YS, KS 15

MEDIUM CHASSIS - SM, EM, YM, KM 17

LARGE CHASSIS - SL, EL, YL 20

Refer to the electrical data plate located on the air conditioner chassis to determine the correct fuse or circuit breaker amperage for your model (See Figure E on Page 16 for electrical receptacle location).

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

WARNING: NEVER CUT OR REMOVE THE GROUNDING PRONG

FROM THE PLUG. NEVER USE EXTENSION CORDS TO OPERATE

AN AIR CONDITIONER.

STEP 11 INSTALL THE SIDE WINGBOARD PANELS – Be sure the

cabinet has been secured to the window sill and that the outside support brackets have been installed as shown in Figure D. Raise the window sash and install the right and left side wingboard panels. (See Figure G).

STEP 12 INSTALL THE WINDOW SEALING GASKETS – Measure

and cut the vinyl window seal gasket (grey color, Item # 12) to

t the width of the window, and install as shown in Figure H.

Pull the window sash down behind the gasket. Measure and cut the dark foam window seal gasket (Item #13) and install it between the upper glass panel and the top part of the lower sash. (See Figure H).

NOTE: FOR REASONS OF SECURITY AND SAFETY, THE

CUSTOMER MUST PROVIDE A MEANS OF PREVENTING

THE WINDOW FROM OPENING.

Figure G

STEP 13 When possible, caulk the outside of the installation with

industrial type caulking to prevent weather leaks.

STEP 14 INSTALL CHASSIS – After installing the shell, slide the chassis

into the shell stopping approximately 3" from full insertion. Stuff

the chassis seal gasket one inch deep between the chassis and the shell (see Figure I ). Begin at either bottom corner and

go up the side, across the top, and down the opposite side. Then push the chassis all the way into the shell for the remaining distance so that the plastic front meets the front edge of the shell.

If chassis seal gasket is not installed, the operation of the unit

will be negatively affected. Operational noise and outside

noise will also be amplied.

STEP 15 Reattach the chassis retainer wire with the same screw as in

Step 3 (See Figure A).

STEP 16 OPTIONAL: The factory assembles the supply cord so that

it exits the left side of the unit. At the consumer’s discretion, the supply cord can be made to exit the right side of the unit.

To do this, remove the black rubber coated cord clamp from

under the far left screw (See Figure I). Replace this screw back into the far left screw hole. Route the supply cord over the top of the return air grille latches and reattach the clamp

to the adjacent screw hole (Figures I & J). Detach the right side cord clamp, route the supply cord through it and reattach. The supply cord should be pulled taut so as not to rest on the return air grille latches.

Figure I

STEP 17 Be sure the lter is in place before installing the return air grille

(See Figure J), and that the electrical cord is properly routed so not to interfere with the installation. (See Step 16.)

STEP 18 Pick up the grille by supporting it from both sides near the bottom

(See Figure K, Note 1.) Lift return air grille and insert the grille's tabs into the bottom slots of the discharge plenum (See Figure K, Note 2). Snap the grille into place by pushing the grille up and onto the unit's latches at the bottom (See Figure K, Notes 3 and 4).

STEP 19 Refer to the Operating Instructions beginning on page 3.

Through-the-wall Installations

The following instructions apply to wood, masonry, brick, concrete or cinder block wall construction

STEP 1 Follow steps 1, 2, 3 and 4 of the "STANDARD SASH WINDOW

INSTALLATION" instructions beginning on page 10.

STEP 2 CABINET PREPARATION – Remove the sill plate from the

cabinet by removing the two nuts and screws retaining the sill plate. Note that the chassis retainer is secured by a right side nut and screw (See Detail 1, Figure A.) Bend the tabs of the sill plate down into its channel at both ends of the plate or cut them off (See Detail 2, Figure A.) Turn the sill plate end to end, 180° and reinstall. Reverse the orientation of nuts and screws so that the head of screw is on bottom of cabinet facing up and nut is on top facing down (See Detail 3, Figure A.) Insure that the chassis retainer is reinstalled as shown in the detail.

STEP 4 CHECKING WIRING AND PLUMBING: Check all wiring and

plumbing inside and outside of the wall to be sure none will be broken where the hole is to be cut.

STEP 5 HOLE CONSTRUCTION: Depending upon size of unit to be

installed, lay out the hole dimensions per the chart below. Cut

and frame in hole to nished dimensions. Use 2" x 4" material for

framing and follow the suggested typical installations in Figure C, D, or E.

NOTE: IF THE WALL CONSTRUCTION IS TYPICAL FRAME

OR 2 x 4 STUDDING WITH BRICK OR STONE VENEERS, LOCATE THE HOLE NEXT TO ONE OF THE STUDS. FOR MASONRY, CONCRETE OR CINDER BLOCK WALLS, LOCATE HOLE FOR CONVENIENCE.
