Your safety and the safety of others are very important.

CAUTION

NOTICE

We have provided many important safety messages in this manual and on your appliance. Always read and obey all

safety messages.

This is a safety Alert symbol.

This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages will follow the safety alert symbol with the word “WARNING”

or “CAUTION”. These words mean:

You can be killed or seriously injured if you do not

follow instructions.

You can receive minor or moderate injury if you do not

follow instructions.

All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you

what will happen if the instructions are not followed.

A message to alert you of potential property damage will have the word “NOTICE”.

Potential property damage can occur if instructions are not followed.

WARNING

Hazardgard Room air conditioner

General Instructions

Your new Friedrich has been carefully engineered and manufactured to give you many years of dependable, efﬁcient operation, main-

taining 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 electri-

cally grounded for your safety. The power supply must

alsobegroundedandmustbeinstalledinaccordancewith

NECArticle501. Thebranchcircuitratingisshownon

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.

Toomuchcapacityisalsohardontheunitasitwillcycleon

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 to-

wardthe"warmer"positionuntilyouhearaclickandthe

compressor goes off. The thermostat will then cycle the

compressor to maintain the selected temperature.

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

6. Donotblocktheairﬂowtoandfromtheunit. Makesure

thelouversaredirectedtogiveevendistributionofair

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 cool-

ing ability of the unit.

8. Ifcoolingisweakandyouhaveveriﬁedthattheﬁlteris

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 aw-

nings.

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

air ﬂow.

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.

Won’t Cool

If the unit operates, but doesn’t cool, check to see that the con-

trols are properly set. Inspect the ﬁlter and clean it thoroughly, if

needed.Checktoseeifthechassissealgasketisinstalled(refer

to installation instructions).

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

temperaturesaslowas45°F(7°C). Freezingshouldonlyoccur

whentheoutsideairisdampandbelow45°F(7°C). Iftheindoor

Maintenance Checklist

coil should ice over while cooling, set the thermostat to the warm-

est 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 cabi-

net 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

forthisservice.

Lubrication

Fan motors are factory lubricated and sealed. No lubrication

is required.

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 ¿lter can be removed for cleaning by opening the front of

the unit and releasing the ¿lter from its retaining clips.

Permanent Split-Capacitor, totally enclosed fan motor to

assure efﬁcient operation even under adverse electrical

conditions. Motor has a special stainless steel shaft to resist

corrosion and a hermetically sealed overload for arc-free

operation.

High capacity compressor with internal hermetically sealed

overload.

Solid-state printed circuit board insulated against corrosion

on conductor paths. Contains transient voltage suppressor

to protect controls against transient voltage spikes. Provides

solid state switches for arc-free operation.

Hot gas bypass low ambient control to permit operation

without freezing at outdoor ambient temperatures as low

as 45°F (7°C).

Environmentally sealed on-off switch and gold plated

contacts in thermostat for corrosion resistance.

Electrodeposited epoxy primer and alkyd enamel, both

oven-baked for an attractive, long-lasting ﬁnish.

Installation Instructions

Models SH15 and SH20

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

THE-WALL INSTALLATIONS

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 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.

STEP 1 Remove the junction box, cover and screw (above items) from the shipping position underneath the fan motor. Install one

junction box mounting leg in the upper left position facing the rear of the junction box.

STEP 2 Remove and discard the plastic bushing from the conduit connector on the side panel of the control compartment. Strip the

black wires only, approximately 1/2 inch (13 mm).

STEP 3 Insert all wires (2 black, 1 green) into the box and thread the box onto the conduit connector until tight. Back off counter

clockwise until the junction box is vertical with the mounting leg at the upper–right position facing the box opening. Be

sure that the shell can ﬁt between this box and the chassis.

Unpacking The Unit

STEP 1 Remove decorative plastic return air grille to a safe area away from the unit.

STEP 2 Remove the installation hardware, wingboard and two (one light colored and one dark colored) gaskets from beneath the

unit,andplacetheminasafeareaawayfromtheunit.

STEP 3 Remove the chassis retainer by removing the far right screw in the basepan (see Figure A); save this screw to reattach the

chassisretainerafterinstallation(Step15). Also,removeanddiscardthetworetainerscrewsandplasticbushingslocated

attherearoftheunit.

STEP 4 While an assistant holds the cabinet stationary, use the hand pull at the front of the base pan (see Figure A) to pull the

chassis out of the cabinet. Remove white foam blocks used to restrain the compressor during shipment. Inspect basepan

for dislodged white blocks, and remove. Do not remove any other foam.
