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.

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.

Chassis Installation
STEP 1Slide the chassis into the cabinet 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). Begin at either bottom corner and go up the side, across the
top, and down the opposite side. 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.
If chassis seal gasket is not installed, the operation of the unit will be negatively affected. Also, the operation noise and
outside noise will be amplified.
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.
