be leak tested to 150 psig, pressure tested to 650 psig, and qualified to UL 199 burst test at 1980 psig. 569J*25
shall be constructed of aluminum fins (copper fins optional) mechanically bonded to internal grooved seamless
copper tubes which are then cleaned, dehydrated, and sealed.
F. Refrigeration Components:
Refrigeration circuit components shall include liquid line service valve, suction line service valve, a full charge of
compressor oil, and a partial holding charge of refrigerant.
G. Controls and Safeties:
1. Minimum control functions shall include:
a. Control wire terminal blocks.
b. Compressor lockout on auto-reset safety until reset from thermostat.
c. Each unit shall utilize the Comfort Alertt Diagnostic Board that provides:
(1.) System Pressure Trip fault code indication
(2.) Short Cycling fault code indication
(3.) Locked Rotor fault code indication
(4.) Open Circuit fault code indication
(5.) Reverse Phase 3 fault code indication
(6.) Welded Contactor fault code indication
(7.) Low Voltage fault code indication
(8.) Anti--short cycle protection
(9.) Phase reversal protection
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. Optional Condenser Coil Materials:
a. Condenser Coil Protective Coating — E--Coated Novation coil:
E--Coated aluminum Novation coils shall have a flexible epoxy polymer coating uniformly applied to all coil
external surface areas without material bridging between fins or louvers. Coating process shall ensure complete
coil encapsulation, including all exposed fin edges. E--Coat thickness of 0.8 to 1.2 mil with top coat having a
uniform dry film thickness from 1.0 to 2.0 mil on all external coil surface areas, including fin edges, shall be
provided. E--Coated coils shall have superior hardness characteristics of 2H per ASTM D3363--00 and cross--
hatch adhesion of 4B--5B per ASTM D3359--02. E--coated products shall have superior impact resistance with
no cracking, chipping or peeling per NSF/ANSI 51--2002 Method 10.2.
3. 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.
