2.Minimum safety devices which are equipped with automatic reset (after resetting first at thermostat), shall in- clude:
a.High discharge pressure cutout.
b.Low pressure cutout. 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 cooling 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 AHRI conditions.
4.Standard unit shall be capable to operate up to 125_F (52_C) and down to 40_F (4_C)
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.
J.Special Features:
1.Low-Ambient Temperature Control:
A low-ambient temperature control shall be available as a factory-installed option or as a field-installed accessory. 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 (-29_C).
2.Unit-Mounted, Non-Fused Disconnect Switch:
Switch shall be factory-installed and internally mounted. NEC and UL-approved non-fused switch shall provide unit power shutoff. Switch shall be accessible from outside the unit and shall provide power off lockout capability. Non-fused disconnect switch cannot be used when unit MOCP electrical rating exceeds 80 amps.
3.Convenience Outlet:
Outlet shall be factory-installed and internally mounted with easily accessible 115-v female receptacle. Outlet shall include 15 amp GFI (ground fault interrupter) receptacle with independent fuse protection. Voltage required to operate convenience outlet shall be provided by a factory-installed step-down transformer. Outlet shall be ac- cessible from outside the unit.
4.Thermostat Controls:
a.Programmable multi-stage thermostat shall have 7-day clock, holiday scheduling, large backlit display, remote sensor capability, and Title 24 compliance.
b.Commercial Electronic Thermostat shall have 7-day time clock, auto-changeover, multi-stage capability, and large LCD (liquid crystal display) temperature display.
5.Louvered hail Guard Package:
Louvered hail guard package shall protect coils against damage from hail and other flying debris.
6.Condenser Coil Grille (Novation coil models 07-14):
Grille shall add decorative appearance to unit and protect condenser coil from large objects and vandalism.
