WATERSIDE – The waterside will be of 300 PSIG
(21 bar) instead of the standard 150 PSIG DWP. 300
PSIG R.F. flanges are included on the Heat Exchanger
nozzles (Factory-Mounted). The companion flanges
will be field-supplied by others.
FLANGES (ANSI/AWWA C-606 COUPLINGS
TYPE) – Consists of two (2) Flange adapters for
grooved end pipe (standard 150 psi [10.5 bar] cooler).
FLOW SWITCH – The flow switch or its equivalent
must be furnished with each unit.
150 PSIG (10.5 BAR) DWP – For standard units.
Johnson Controls model F61MG-1C Vapor-proof
SPDT, NEMA 4X switch (150 PSIG [10.5 bar] DWP),
-20 °F to 250 °F (-29 °C to 121 °C), with 1” NPT con-
nection for upright mounting in horizontal pipe (Field-
Mounted).
300 PSIG (21 BAR) DWP – For units with optional
300 PSIG (21 bar) DX cooler. McDonnell & Miller
model FS74W Vapor-proof SPDT, NEMA 4X switch

to 149 °C), with 1¼ inch MPT connection for upright
mounting in horizontal pipe (Field-Mounted).
DIFFERENTIAL PRESSURE SWITCH – Alterna-
tive to an above mentioned flow switch. Pretempco
model DPS300AP40PF-82582-5 (300 psi max. work-
ing pressure), SPDT 5 amp 125/250VAC switch, Range
0 – 40 PSID, deadband 0.5 – 0.8 psi, with 1/4” NPTE
Pressure Connections.
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
condenser coils. This is another choice for seashore
and other corrosive applications (with the exception
of strong alkalies, 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 ex-
posed to acid rain).
ENCLOSURE PANELS (UNIT) – Tamperproof En-
closure Panels prevent unauthorized access to units.
Enclosure Panels can provide an aesthetically pleas-
ing 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 visually screen
unit components. Unrestricted air flow is permitted
through generously sized louvered openings. This op-
tion is applicable for any outdoor design ambient tem-
perature up to 115 °F (46 °C) (Factory-Mounted).
SOUND REDUCTION OPTIONS
SOUND ATTENUATION – One or both of the fol-
lowing 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 options 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”
(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).
ULTRA QUIET FANS – Lower RPM, 8-pole fan mo-
tors are used with steeper-pitch fans (Factory-Mount-
ed).
VIBRATION ISOLATORS – Level adjusting, spring
type 1” (25.4mm) or seismic deflection or neoprene
pad isolators for mounting under unit base rails (Field-
Mounted).
