OPERATION AND CARE INSTRUCTIONS

Page 3
WELCOME TO YEARS OF ECONOMICAL COMFORT
WITH YOUR NEW FRIEDRICH HAZARDGARD
ROOM AIR CONDITIONER
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 weakand 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-facing windows with awnings.
12. Keep window coverings away from the unit to provide free air flow.
PART 1 — GENERAL INSTRUCTIONS

Page 4
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.
WON’TCOOL
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’TRUN
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 sizetime-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.
PART 3 — MAINTENANCE CHECKLIST
The filter can be removed for cleaning by opening the
front of the unit and releasing the filter from its retaining
clips.

FUNCTION CONTROL (POWER)
This switch is a double pole, single throw toggle
switch.
ON - Turns everything on.
OFF - Turns everything off.
TEMPERATURE CONTROL
The knob at the bottom is the thermostat which is a
cross ambient type used to maintain the desired
comfort level. The thermostat reacts only to a change
in temperature at the bulb location - turn the knob
clockwise to set cooler, counterclockwise for warmer.
Friedrich leads again with the first UL Listed Room Air Conditioners designed to cool living
quarters and other enclosures situated in hazardous locations where specific volatile
flammable liquids or gases are handled or used with enclosed containers or systems.
Friedrich HazardGard®room air conditioners are designed to meet the National Electrical
Code, Article 500 requirements for Class I, Division 2, Groups A, B, C, D Hazardous locations
and are the only air conditioners UL Listed for this application.
THIS UNIT IS LISTED BY UNDERWRITERS LABORATORIES FOR USE IN
CLASS I, DIVISION 2, GROUPS A, B, C, D HAZARDOUS LOCATIONS.

SECTION I: ELECTRICAL REQUIREMENTS
ALL FIELD WIRING MUST MEET THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE (ANSI/NFPA 70)
ARTICLE 501.
THE FIELD-PROVIDED CIRCUIT 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
informationbelow.
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.

SHELL (CABINET) PREPARATION:
Itwill benecessary to relocate the sillplate of the cabinet 2"back fromits shipping position, and theshell guides 4" forward, to
the forward-most hole 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 the field-installed conduit will retain the chassis in the shell.
IFTHIS 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 the rear-most holes 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.)

CHASSIS INSTALLATION
STEP 1. Slidethe chassisinto thecabinet stopping approximately 3" from full insertion. Stuff the chassis seal gasket (Item
#14) one inch deep between the chassis and the cabinet (See Figure P). Make sure that the gasket is behind
the conduit connector (furthest from you). Push the chassis into the shell the remaining distance so that the
plastic front shrouds the front edge of the shell. Fasten the junction box mounting foot to the shell with the sheet
metal screw.
NOTE: Field wiring must be provided to this junction box in accordance with NATIONAL ELECTRIC CODE
ARTICLE 501. Field and equipment grounds are to be terminated at the post in the junction box with
the green screw provided. Equipment power leads are to be connected with the field supply by means
of wire nuts (not provided). Install the gasket and cover plate onto the junction box.
