Product Description
The following options provide added protection:
Black fin condenser coils – Condenser coils con-
structed using black epoxy coated Aluminum fin stock
for corrosion resistance comparable to copper fin coils
in typical seashore locations.
Copper fin condenser coils – Coils constructed with
corrosion resistant copper fins. Not recommended in
areas where units may be exposed to acid rain.
Phenolic coated condenser coils – Completed con-
denser coil assemblies are covered with a cured Phe-
nolic coating. Probably the most suitable selection for
seashore locations where salt spray may come into con-
tact with the fins, and other corrosive applications ex-
cept: strong alkalis, oxidizers, and wet bromine, chlo-
rine, and fluorine in concentrations greater than 100
PPM.
DX COOLER OPTIONS:
21 bar (300 PSIG) Waterside Design Working
Pressure – The DX cooler waterside is designed and
constructed for 21 bar (300 PSIG) working pressure.
(Factory-mounted.)
38 mm (1-1/2") Insulation – Double thickness insu-
lation provided for enhanced efficiency.
Flange Accessory – Consists of raised face flanges to
convert grooved water nozzles to flanged cooler
connections. Includes companion flanges for field-
mounting.
Remote DX Cooler – Includes the main condensing
unit less the cooler, refrigerant and liquid line devices.
The insulated cooler and field accessory kits per refrig-
erant circuit are supplied separately. The condensing
unit is shipped with an R-22 holding charge and the
cooler is shipped with a nitrogen holding charge.
Flow Switch Accessory – Johnson Controls model
F61MG-1C Vapor-proof SPDT, NEMA 4X switch, 10
bar (150 PSIG) DWP, -29°C to 121°C (-20°F to 250°F),
with 1" NPT (IPS) connection for upright mounting in
horizontal pipe. A flow switch must be field installed
with each unit.
Star-Delta Compressor Motor Starter – Provides
approximately 65% reduced inrush current compared
to across-the-line start. (Factory-mounted.)

UNIT ENCLOSURES
Wire enclosure – Heavy gauge welded wire mesh
guards mounted on the exterior of the unit. (Factory or
field-mounted.)
Louvered panels and wired guards – Louvered pan-
els mounted over the exterior condenser coil faces, and
heavy gauge welded wire mesh guards mounted around
the bottom of the unit.0 (Factory or field-mounted.)
Louvered panels (condenser coils only) – Louvered
panels are mounted over the exterior condenser coil
faces on the sides of the unit to visually screen and pro-
tect the coils. (Factory or field-mounted.)
Louvered panels (full unit) enclosure – Louvered
panels over condenser coils and around the bottom of
the unit. (Factory or field-mounted.)
FANS
High static fans: Fans and motors suitable for High
External Static conditions to 100 Pa.
SOUND REDUCTION OPTIONS
Low speed fans – Reduced RPM fan motors and alter-
native fan selection for low noise applications.
Compressor sound enclosures – Acoustically
treated metal compressor enclosures. Includes a com-
pressor mounted temperature transducer to prevent
overheating.
VIBRATION ISOLATION
Neoprene pad isolation – Recommended for normal
installations (Field-mounted).
25 mm (1") spring isolators – Level adjustable, spring
and cage type isolators for mounting under the unit base
rails. (Field-mounted.)
51 mm (2") seismic spring isolators – Restrained
Spring-Flex Mountings incorporate welded steel hous-
ing with vertical and horizontal limit stops. Housings
designed to withstand a minimum 1.0 g accelerated force
in all directions to 51 mm (2"). Level adjustable, deflec-
tion may vary slightly by application. (Field-mounted.)
