d. E-Coated Copper 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 mil 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 resis-
tance 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
copper-fins mechanically bonded to copper-
tubes with copper tube sheets. Galvanized
steel tube sheets shall not be acceptable. A
polymer strip shall prevent coil assembly
from contacting sheet metal coil pan to
maintain coating integrity and minimize cor-
rosion potential between the coil and pan.
6. Thermostat Controls:
a. Programmable multi-stage thermostat with
7-day clock, holiday scheduling, large backlit
display, remote sensor capability, and
Title 24 compliance.
b. TEMP System programmable communicat-
ing multi-stage thermostat with fan switch,
timeclock, LCD display, °F/°C capability,
and CCN (Carrier Comfort Network)
compatibility.
c. Commercial Electronic Thermostat with
7-day timeclock, auto-changeover, multi-
stage capability, and large LCD temperature
display.
d. Non-programmable thermostat with fan
switch subbase.
