WELCOME TO YEARS OF ECONOMICAL COMFORT

WITH YOUR NEW FRIEDRICH HAZARDGARD

ROOM AIR CONDITIONER

PART 1 — GENERAL INSTRUCTIONS

Your new Friedrich has been carefully engineered and manufactured to give you many years of dependable, efficient operation, maintaining a comfortable temperature and humidity level. Many extra features have been built into your unit to assure quiet operation, the greatest circulation of cool, dry air, and the most economic operation.

Here are some suggestions to help you use your new Friedrich most efficiently:

1.Carefully read and follow the installation instructions.

2.Your Friedrich HazardGard room air conditioner is electrically grounded for your safety. The power supply must also be grounded and must be installed in accordance with NEC Article 501. The branch circuit rating is shown on the nameplate for each model.

3.Make sure the unit is the right capacity for the area to be cooled. Too little capacity makes the unit work too hard, using more electricity than needed and increasing wear. Too much capacity is also hard on the unit as it will cycle on and off too rapidly, and cannot control humidity as well.

4.When you first turn on your Friedrich, set the thermostat to its coldest position to cool the room. When the desired temperature is reached, turn the thermostat control toward the "warmer" position until you hear a click and the compressor goes off. The thermostat will then cycle the compressor to maintain the selected temperature.

5.Clean the filter frequently (See General Maintenance).

6.Do not block the air flow to and from the unit. Make sure the louvers are directed to give even distribution of air throughout the room. Caution: If air is directed into a restricted area such as behind a bed or into a corner, this may cause the unit to cycle on and off rapidly, which could damage your unit.

7.A dirty filter or improperly set controls can affect the cooling ability of the unit.

8.If cooling is weak and you have verified that the filter is clean and the controls are properly set, the unit may be low on refrigerant, and you should call your Friedrich service provider to check the unit.

9.Keep blinds, shades and drapes closed on the sunny side of the room being cooled.

10.Proper insulation helps your unit maintain the desired inside temperature.

11.Whenever possible, shade west-facingwindows with awnings.

12.Keep window coverings away from the unit to provide free air flow.

PART 2 — FILTER INFORMATION

The filter in your Friedrich removes dust, pollen and other impurities from the air as they are drawn through the unit. The filter is permanent and reusable, and has a germicidal treatment which is not affected by washing.

A clogged, dirty filter reduces the air flow through the unit and reduces its efficiency. You should check the filter every seven to ten days, depending on the amount your unit is used. Clean the filter regularly.

Filter Retainer Clips

The filter can be removed for cleaning by opening the front of the unit and releasing the filter from its retaining clips.

PART 3 — MAINTENANCE CHECKLIST

WON’T COOL

If the unit operates, but doesn’t cool, check to see that the controls are properly set. Inspect the filter and clean it thoroughly, if needed.

WON’T RUN

If the unit does not operate at all, check that the power supply connections are tight. Check for blown fuses or tripped circuit breakers. Replace blown fuses with the proper size time-delay fuse. The nameplate on the unit shows the proper fuse size. After restoring power, wait three minutes before restarting the unit.

INSIDE COIL FREEZES UP

Your Friedrich HazardGard is designed not to freeze with outdoor temperatures as low as 45°F (7°C). Freezing should only occur when the outside air is damp and below 45°F (7°C). If the indoor coil should ice over while cooling, set the thermostat to the warmest position until the ice on the coil is gone. Setting the thermostat to a slightly warmer position will probably keep ice from forming on the coil. A dirty filter will contribute to icing.

CLEANING

The front grille of your Friedrich, as well as the complete cabinet may be cleaned with warm water and a mild detergent. The coils and base pan should be cleaned periodically for the most efficient operation. We suggest you call your Friedrich dealer for this service.

LUBRICATION

Fan motors are factory lubricated and sealed. No lubrication is required.

INSTALLATION INSTRUCTIONS

Models SH14 and SH20

NOTE: THIS MANUAL INCLUDES INSTALLATION INSTRUCTIONS FOR BOTH WINDOW MOUNT AND THROUGH- THE-WALLINSTALLATIONS

SECTION I: ELECTRICAL REQUIREMENTS

ALL FIELD WIRING MUST MEET THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE (ANSI/NFPA 70) ARTICLE 501.

THE FIELD-PROVIDEDCIRCUIT PROTECTION DEVICE (HACR CIRCUIT BREAKER OR TIME DELAY FUSE) MUST NOT EXCEED THE AMPACITY INDICATED ON THE PRODUCT NAMEPLATE.

IMPORTANT: 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 frequency (hertz) as marked on the data plate located on the chassis. Only alternating current (A.C.), no direct current (D.C.), can be used.

An overloaded circuit will invariably cause malfunction or failure of the air conditioner; therefore, it is extremely important that the electrical power is adequate. Consult your dealer or power company if in doubt.

The following instructions are for HAZARDGARD models and cabinet sizes listed below.

SECTION IV

SHELL (CABINET) PREPARATION:

It will be necessary to relocate the sill plate of the cabinet 2" back from its shipping position, and the shell guides 4" forward, to the forward-mosthole in the shell rail. Discard the chassis retainer wire disconnected in Section II, Step 3. The junction box mounting leg from Section VI, Step 1, and thefield-installedconduit will retain the chassis in the shell.

IF THIS INSTALLATION IS FOR A SASH WINDOW – With the wide flange and pilot holes of the sill plate forward, put the screws/nuts in the rear holes of the sill plate and third shell hole from the front (the center of three square holes). Anchor the side angles (Item #6) by engaging the tabs at each end of the sill plate with the bottom loops of the side angle. Engage the tabs at each end of the top angle (Item #5) with the top loops of the side angle. Install two (2) screws (Item #7) to secure the top angle tabs and the side angle to therear-mostholes in the side of the cabinet (See Figure B, below).

IF THIS INSTALLATION IS THROUGH A WALL – Turn the sill plate end to end so that the wide flange with pilot holes will be over the wall header (towards the rear) and two inches from the front of the cabinet. Bend the tabs into the channel of the sill plate, put the screws/nuts in the front holes of the sill plate and into the second shell hole from the front. Use one bolt on each side to secure the sill plate to the cabinet. (See Figure C, below.)
