Congratulations!
Thank you for your decision to purchase the Friedrich Hazardgard (Hazardous Duty 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.
General Instructions
This Installation and Operation Manual has been designed to insure maximum satisfaction in the performance of your unit. For
years of trouble-free service, please follow the installation instructions closely. We cannot overemphasize the importance of
proper installation. We have added new information to the basic instructions to help you achieve proper installation.
WARNING
Refrigeration system under high pressure.
Do not puncture, heat, expose to flame or incinerate.
Only certified refrigeration technicians should service
this equipment.
R410A systems operate at higher pressures than R22
equipment. Appropriate safe service and handling
practices must be used.
Only use gauge sets designed for use with R410A. Do
not use standard R22 gauge sets.
Here are some suggestions to help you use your
new Friedrich most efficiently:
1. Carefully read and follow the installation instructions.
2. Make sure the unit is the right capacity for the area to be
cooled. An undersized unit makes the unit work too hard,
using more electricity than needed and increases wear. An
oversized unit will cycle on and off too rapidly, and therefore
cannot control humidity very well.
3. 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
compressor to maintain the selected temperature.
4. Clean the filter frequently (See Filter Information)
5. 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 directed into a restricted
area such as a corner, this may cause the unit to cycle on and
off rapidly, which could damage your unit.
6. A dirty filter or improperly set controls can affect the cooling
ability of the unit.
7. 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.
8. Keep blinds, shades and drapes closed on the sunny side of
the room being cooled.
9. Proper room insulation helps your unit maintain the desired
inside temperature.

WARNING
Please read this manual thoroughly prior to equipment
installation or operation.
It is the installer’s responsibility to properly apply and
install the equipment. Installation must be in
conformance with the NFPA 70-2008 National Electric
Code or current edition, International Mechanic Code
2009 or current edition and any other applicable local
or national codes.
Failure to do so can result in property damage,
personal injury or death.
10. Whenever possible, shade west-facing windows with
awnings , trees, or window tinting.
.
11. Keep window treatments away from the unit to provide free
air flow.
Your safety and the safety of others are very important.
We have provided many important safety messages in this manual
and on your appliance. Always read and obey all safety messages.

FilterInformation
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 periodic 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’tRun
If the unit does not operate at all, check that the power supply
connections are present and tight. Check for blown fuses or

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

UnpackingThe Unit
STEP1 Remove decorative plastic return air grille to a safe area away from the unit.
STEP2
Remove the installation hardware, wingboard and two
(one lighter colored and one dark colored) gaskets from beside the
unit, and place them in a safe area away from the unit.
STEP3 Remove the chassis retainer by removing the far right screw in the basepan (see Figure A); save this screw to reattach the
chassis retainer after installation.
Also, remove and discard the two retainer screws and plastic bushings located at the rear
of the unit.
STEP4 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.

Remove the junction box, cover and screw 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. (See Figure A1.)
Remove and discard the threaded plastic bushing wire protector from the conduit connector on the side panel of the
control compartment. Strip the black wires only, approximately 1/2 inch (13 mm).
Insert all wires (2 black, 1 green) into the rear of the junction 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 slide between this box and the chassis.

Chassis Installation
STEP 1 Slide 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 t
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 amplifi ed.

Excessive Weight Hazard
Use two or more people when
installing your air conditioner.
Failure to do so can result in
back or other injury.
CAUTION
Cut/Sever
Although great care has been
taken to minimize sharp edges
in the construction of your unit,
use gloves or other hand
protection when handling unit.
Failure to do so can result in minor
to moderate personal injury.
WARNING
Explosion Hazard
Electrically connect unit in accordance with NEC
Code Article 501. Failure to do so can result in
death, explosion, fire, or electrical shock.
