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 dura-
bility shall be confirmed through testing to no less
than 1000 hours salt spray per ASTM B117-90.
Coil construction shall be aluminum fins mechani-
cally 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 capabil-
ity, and large LCD temperature display.
5. Hail Guard Package:
Hail guard package shall protect coils against dam-
age 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 conve-
nience outlet shall be provided by a factory-installed
step-down transformer. Shall be accessible from out-
side the unit.
