additional application recommendations, refer to FORM
150.12-ES1. (Factory-mounted.)
PRE-COATED FIN CONDENSER COILS – The air-
cooled condenser coils are constructed of black ep-
oxy-coated aluminum ns. This can provide corrosion
resistance comparable to copper-n coils in typical
seashore locations. Either these or the post-coated coils
(below), are recommended for units being installed at
the seashore or where salt spray may hit the unit.
POST-COATED DIPPED CONDENSER COILS – The
unit is built with dipped-cured condenser coils. This is
another choice for seashore and other corrosive appli-
cations (with the exception of strong alkalies, oxidizers
and wet bromine, chlorine and uorine in concentrations
greater than 100 ppm).
COPPER FIN CONDENSER COILS – The unit con-
structed with condenser coils which have copper ns.
(This is not recommended for units in areas where they
may be exposed to acid rain.)
ENCLOSURE PANELS (UNIT) – Tamperproof Enclosure
Panels prevent unauthorized access to units. Enclosure
Panels can provide an aesthetically pleasing alternative
to expensive fencing. Additionally, for proper head pres-
sure control, YORK recommends the use of Condenser
Louvered Panels for winter applications where wind gustss
may exceed ve miles per hour. The following types of
enclosure panels are available:
WIRE PANELS (Full Unit) – Consists of welded wire-
mesh guards mounted on the exterior of the unit. Pre-
vents unauthorized access, yet provides free air ow.
(Factory-mounted.)
WIRE/LOUVERED PANELS – Consists of welded wire-
mesh panels on the bottom part of unit and louvered
panels on the condenser section of the unit. (Factory-
mounted).
LOUVERED PANELS (Condenser Coil Only) – Lou-
vered panels are mounted on the sides and ends of the
condenser coils for protection. (Factory-mounted.)
LOUVERED PANELS (Full Unit) – Louvered panels
surround the front, back, and sides of the unit. They
prevent unauthorized access and visually screen unit
components. Unrestricted air ow is permitted through
generously sized louvered openings. This option is ap-
plicable for any outdoor design ambient temperature up
to 115°F (46°). (Factory-mounted.)
SOUND ATTENUATION – One or both of the following
sound attenuation options are recommended for residential
or other similar sound sensitive locations:
COMPRESSOR ACOUSTIC SOUND BLANKET
– Each compressor is individually enclosed by an
acoustic sound blanket. The sound blankets are made
with one layer of acoustical absorbent textile ber of
5/8" (15mm) thickness; one layer of anti-vibrating heavy
material thickness of 1/8" (3mm). Both are closed by two
sheets of welded PVC, reinforced for temperature and
UV resistance. (Factory-mounted.)
LOW SOUND FANS – Lower RPM, 8-pole fan motors
are used with steeper-pitch fans. (Factory-mounted.)
VIBRATION ISOLATORS – Level adjusting, spring type 1"
(25.4mm) or seismic deection or neoprene pad isolators
for mounting under unit base rails. (Field-mounted.)
