This low-ambient control shall regulate speed of the condenser-fan motors in response to the saturated condensing temperature of the unit. The control shall maintain correct condensing pressure at outdoor temperatures down to –20 F. 2. Gage Panel Package: Gage panel package shall include a suction and discharge pressure gage. 569D072- 120, 576C120, 569F120 31 569D072- 120, 576C120, 569F120 569D072- 120, 576C120, 569F120 GUIDE SPECIFICATIONS — 569F120 (cont) 3. Optional Condenser Coil Materials: a. Pre-Coated Aluminum-Fin Coils: Shall have a durable epoxy-phenolic coating to provide protection in mildly corrosive coastal environments. Coating shall be applied to the aluminum fin stock prior to the fin stamping process to create an inert barrier between the aluminum fin and copper tube. Epoxy-phenolic barrier shall minimize galvanic action between dissimilar metals. b. E-Coated Aluminum-Fin Coils: Shall have a flexible epoxy polymer coating uniformly applied to all coil surface areas without material bridging between fins. Coating process shall ensure complete coil encapsulation. Color shall be high gloss black with gloss requirements of 60° of 65 to 90% per ASTM D523-89. Uniform dry film thickness from 0.8 to 1.2 mil on all surface areas including fin edges. Superior hardness characteristics of 2H per ASTM D3363-92A and cross hatch adhesion of 4B-5B per ASTM D3359-93. Impact resistance shall be up to 160 in./lb (ASTM D2794-93). Humidity and water immersion resistance shall be up to a minimum of 1000 and 250 hours respectively (ASTM D2247-92 and ASTM D870-92). Corrosion durability shall be confirmed through testing to no less than 1000 hours salt spray per ASTM B117-90. Coil construction shall be aluminum fins mechanically bonded to copper tubes. 4. Thermostat Controls: a. Programmable multi-stage thermostat with 7-day clock, holiday scheduling, large backlit display, remote sensor capability, and Title 24 compliance. b. Commercial Electronic Thermostat with 7-day timeclock, auto-changeover, multi-stage capability, and large LCD temperature display. 5. Hail Guard Package: Hail guard package shall protect coils against damage from hail and other flying debris. 6. Condenser Coil Grille: Grille shall add decorative appearance to unit and protect condenser coil after installation. 7. Unit-Mounted, Non-Fused Disconnect Switch: Shall be factory-installed, internally mounted. NEC and UL approved non-fused switch shall provide unit power shutoff. Shall be accessible from outside the unit and shall provide power off lockout capability. 8. Convenience Outlet: Shall be factory-installed and internally mounted with easily accessible 115-v female receptacle. Shall include 15 amp GFI receptacle with independent fuse protection. Voltage required to operate convenience outlet shall be provided by a factory-installed step-down transformer. Shall be accessible from outside the unit. 32 MODEL NUMBER NOMENCLATURE 566DE X150 000–– 566DE X150 000–– 566D — Commercial Air-Cooled Condensing Unit With Semi-Hermetic Compressor 566E — Dual Circuit Commercial Air-Cooled Condensing Unit With Scroll Compressors Voltage Designation E — 460-3-60 P — 208/230-3-60 T — 575-3-60 Heating X—None *Contact your local representative for more details.
