Manual reset at the unit

Electrical overload protection through the use of def- inite-purpose contactors and calibrated, ambient compensated, magnetic trip circuit breakers. Circuit breakers shall open all 3 phases in the event of an overload in any one of the phases or a single-phase condition.

H.Operating Characteristics:

1.The capacity of the condensing unit shall meet or exceed_____Btuh at a suction temperature of_____ F. The power consumption at full load shall not exceed_____ kW.

2.The combination of the condensing unit and the evaporator or fan coil unit shall have a total net cool- ing capacity of _____ Btuh or greater at conditions of

_____ cfm entering-air temperature at the evaporator at _____ F wet bulb and _____ F dry bulb, and air entering the condensing unit at _____ F.

3.The system shall have an EER of _____ Btuh/Watt or greater at standard ARI conditions.

I.Electrical Requirements:

1.Nominal unit electrical characteristics shall be _____ v, 3-ph, 60 Hz. The unit shall be capable of satisfactory operation within voltage limits of _____ v to _____ v.

2.Unit electrical power shall be single point connection.

3.Unit control circuit shall contain a 24-v transformer for unit control, with capacity to operate an indoor fan interlock.

J.Special Features:

1.Low-Ambient Temperature Control (Factory-Installed Option or Field-Installed Accessory):

Control shall regulate fan motor speed in response to the saturated condensing temperature of the unit. The control shall allow the unit to operate down to an ambient temperature of –20 F.

2. Electric Solenoid Unloader Accessory:

Unloader valve piston, coil, and hardware shall be supplied to convert the pressure-operated compres- sor unloader to electric unloading.

3. Hail Guard Package:

Hail guard package shall protect coil against hail and other flying debris.

4. Condenser Coil Grille Package:

Grilles shall protect the condenser coils after unit installation.

5.Optional Condenser Coil Materials: a. Pre-Coated Aluminum-Fin Coils:

Shall have a durable epoxy-phenolic coating to provide protection in mildly corrosive coastal envi- ronments. Coating shall be applied to the alumi- num 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 uni- formly 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 65-90% 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

250hours 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 con- struction shall be aluminum-fins mechanically bonded to copper tubes.

6.Thermostat Control Accessory:

a.Commercial Electronic Thermostat with 7-day timeclock, auto-changeover, multi-stage capabil- ity, and large LCD temperature display.

b.Commercial Electronic Non-programmable Ther- mostat with auto-changeover, multi-stage capabil- ity, and large LCD temperature display.

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. Not to be used when rooftop electrical rating exceeds 80 amperes.

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.
