(5) Access to the front and back of the cabinet for routine operation and
servicing and for necessary maintenance actions.
(6) Access to the top of the cabinet for removal of the top panel and
sufficient headroom to allow maintenance actions and internal component removal
and installation through the top panel opening.
(7) A source of 115 volt, single phase, 50/60 hertz input power rated at
17.3 amps.
The power source outlet should be located as near as possible to the
installed location of the air conditioner.
The power source wiring must include a
disconnect switch.
However, provisions should be made to insure that power is not
disconnected durinq normal operation and that the disconnect is not used to turn
off the air conditioner for normal shut-down.
(8) An earth ground capable of handling 17.3 amps.
(9) Check that no source of dangerous or objectionable
near the fresh air intake.
(10) If possible make use of terrain features such as
fumes are located
trees and buildings to
provide a shaded location.
This will minimize the cooling load on the air condi-
tioner.
(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.
(See fig. 4-2.) Consideration should be
given to service of internal components.
All openings around air conditioner must
be sealed air tight.
c.
Inside installation.
Manufacture an arrangement of ducts for the condenser
intake and discharge air openings, and the fresh air damper intake and/or CBR
filter intake, if installed.
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 screen and/or the air intake on the CBR filter 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 the fresh air screen supplied with the air conditioner and relocated
and installed on the new duct work.
Adequate replacements or some other
arrangement of these items may be provided.
Easy access to fresh or return air filters must be provided.
Filters may be left in position in unit or relocated in duct
work.
Some installations (filters relocated in duct work)
may require different size filters.
