Condenser And Cabinet Options; Sound Reduction Options - York YCAL Series Installation Operation & Maintenance

SECTION 2 - PRODUCT DESCRIPTION
Remote DX Cooler
A split system arrangement with the cooler, leaving &
return water sensors, liquid line solenoid valves, filter
driers, sightglasses and TXVs shipped loose for field
connection to the air-cooled condensing section. The
DX cooler and outdoor section will have a nitrogen
holding charge. Interconnecting rigid piping, wiring
and refrigerant are by others. Includes Johnson Con-
trols Service startup. See Form 150.62-NM1.1 for
other application information (this option includes the
Crankcase Heater option) (Field-Mounted).

Condenser and Cabinet Options

Condenser coil protection against corrosive environ-
ments is available by choosing any of the following
options. For additional application recommendations,
refer to Form 150.12-ES1 (Factory-Mounted).
Pre-Coated Fin Condenser Coils
The unit's coils are constructed with black epoxy coated
aluminum fins. This can provide corrosion resistance
comparable to copper-fin coils in typical seashore loca-
tions. 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's coils are constructed with dipped-cured con-
denser coils. This is another choice for seashore and
other corrosive applications (with the exception of
strong alkalis, oxidizers and wet bromine, chlorine and
fluorine in concentrations greater than 100 ppm).
Copper Fin Condenser Coils
The unit's coils are constructed with copper fins. (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 aes-
thetically pleasing alternative to expensive fencing.
Additionally, for proper head pressure control, YORK
recommends the use of:
Louvered Panels (Full Unit)
Louvered panels surround the front, back, and sides of
the unit. They prevent unauthorized access and visu-
ally screen unit components. Unrestricted air flow is
permitted through generously sized louvered openings.
This option is applicable for any outdoor design ambi-
ent temperature up to 115°F (46°C) (Factory-Mount-
ed).

Sound Reduction Options

Sound Attenuation
One or both of the following sound attenuation options
are recommended for residential or other similar sound-
sensitive locations. Louvered Panels can be ordered for
winter applications where wind gusts may exceed five
miles per hour. The following types of enclosure op-
tions are available:
Compressor Acoustic Sound Blanket
Each compressor is individually enclosed by an acous-
tic sound blanket. The sound blankets are made with
one layer of acoustical absorbent textile fiber of 5/8 in.
(15 mm) thickness; one layer of anti-vibrating heavy
material thickness of 1/8 in. (3 mm). Both are closed
by two sheets of welded PVC, reinforced for tempera-
ture and UV resistance (Factory-Mounted).
Ultra Quiet Fans
Lower RPM, 8-pole fan motors are used with steeper-
pitch fans (Factory-Mounted).
Vibration Isolators
Level adjusting, spring type 1 in. (25.4 mm) or seismic
deflection or neoprene pad isolators for mounting un-
der unit base rails (Field-Mounted).
