(11) If possible, avoid locations where the condenser and fresh air intakes will be laden with dust, dirt, soot,
smoke, or other debris.
b. Through the Wall Installation. Prepare an opening in the wall large enough to slide the air conditioner through.
Consideration should be given to service of internal components. All openings around air conditioner must be sealed air
tight. Refer to Figure 3-1 for Installation Dimensions.
c. Inside Installation Manufacture an arrangement of ducts for the condenser intake and discharge air openings
and the fresh air damper intake. Ducts may be made for attachment to the air conditioner cabinet using the mounting
holes for the condenser inlet and outlet guards, and the fresh air filter frame or some other arrangement may be made.
Prepare appropriate openings in an exterior wall for the ducts. Ducts may be designed to use the condenser inlet and
outlet guards and fresh air filter and frame supplied with the air conditioner and relocated and installed on new duct work.
Adequate replacements or some other arrangement of these items may be provided.
CAUTION
Easy access to air filters must be provided. Filters may be left in unit or relocated
in duct work. Some installations (filters relocated in duct work) may require
different size filters.
d. Outside Installation. Manufacture an arrangement of ducts for the conditioned air intake and discharge air.
Ducts may be made for attachment to the air conditioner cabinet using the mounting holes for the conditioned air intake
and discharge guards or some other arrangement may be made. Ducts may also be made for installation of the
conditioned air intake and discharge guards on the inside ends or replacements for these items may be used. Prepare
appropriate openings in the appropriate wall for the ducts.
NOTE
Retain all items removed from air conditioner. Store them in a safe place. These
parts must be reinstalled prior to returning air conditioner to supply. For a list of
required items, see Appendix C.
3-8. AIR CONDITIONER PREPARATION FOR INSTALLATION. Determine which input power is to be used and select
the proper input power connector. The air conditioner is shipped from the manufacturer with the primary input power
connector J11 as the source of input power. Refer to MIL-HDBK-116, Environmental Control of Small Shelters, for
additional general information. For alternate installation methods, some preparation is necessary. The unit is designed to
provide for several basic types of installation. See the following paragraphs for instructions only if they are applicable to
your requirements.
(1) Remote mounting of control panel. (See para. 3-9).
(2) Installations that require removal of the fabric cover. (See para. 3-10.)
(3) Alternate input power cable connections to connector J8. (See para. 3-11.)
