5.Standard All Aluminum Novation Coils:

g.Humidity and water immersion resistance shall be up to minimum 1000 and 250 hours respectively (ASTM D2247-92 and ASTM D870-92).

h.Corrosion durability shall be confirmed through testing to be no less than 1000 hours salt spray per ASTM B117-90.

5.Standard All Aluminum Novation Coils:

a.Standard condenser coils shall have all aluminum NOVATION Heat Exchanger Technology design consisting of aluminum multi port flat tube design and aluminum fin. Coils shall be a furnace brazed design and contain epoxy lined shrink wrap on all aluminum to copper connections.

b.Condenser coils shall be leak tested to 150 psig, pressure tested to 650 psig, and qualified to UL 1995 burst test at 1980 psig.

6.Optional E-coated aluminum-fin, aluminum tube condenser coils:

a.Shall have a flexible epoxy polymer coating uniformly applied to all coil external surface areas without mater- ial bridging between fins or louvers.

b.Coating process shall ensure complete coil encapsulation, including all exposed fin edges.

c.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.

d.Shall have superior hardness characteristics of 2H per ASTM D3363-00 and cross-hatch adhesion of 4B-5B per ASTM D3359-02.

e.Shall have superior impact resistance with no cracking, chipping or peeling per NSF/ANSI 51-2002 Method 10.2.

23 81 19.13.K. Refrigerant Components

1.Refrigerant circuit shall include the following control, safety, and maintenance features:

a.Fixed orifice metering system shall prevent mal-distribution of two-phase refrigerant by including multiple fixed orifice devices in each refrigeration circuit. Each orifice is to be optimized to the coil circuit it serves.

b.Refrigerant filter drier - Solid core design.

c.Service gauge connections on suction and discharge lines.

d.Pressure gauge access through a specially designed access port in the top panel of the unit.

2.There shall be gauge line access port in the skin of the rooftop, covered by a black, removable plug.

a.The plug shall be easy to remove and replace.

b.When the plug is removed, the gauge access port shall enable maintenance personnel to route their pressure gauge lines.

c.This gauge access port shall facilitate correct and accurate condenser pressure readings by enabling the read- ing with the compressor access panel on.

d.The plug shall be made of a leak proof, UV-resistant, composite material.

3.Compressors

a.Unit shall use fully hermetic, scroll compressor for each independent refrigeration circuit.

b.Compressor motors shall be cooled by refrigerant gas passing through motor windings.

c.Compressors shall be internally protected from high discharge temperature conditions.

d.Compressors shall be protected from an over-temperature and over-amperage conditions by an internal, motor overload device.

e.Compressor shall be factory mounted on rubber grommets.

f.Compressor motors shall have internal line break thermal, current overload and high pressure differential pro- tection.

g.Crankcase heaters shall not be required for normal operating range, unless required by compressor manufac- turer due to refrigerant charge limits.

23 81 19.13.L. Filter Section

1.Filters access is specified in the unit cabinet section of this specification.

2.Filters shall be held in place by a pivoting filter tray, facilitating easy removal and installation.

3.Shall consist of factory installed, low velocity, throw-away 2-in. thick fiberglass filters.

4.Filters shall be standard, commercially available sizes.

5.Only one size filter per unit is allowed.

23 81 19.13.M. Evaporator Fan and Motor

1.Evaporator fan motor:

a.Shall have permanently lubricated bearings.

b.Shall have inherent automatic-reset thermal overload protection or circuit breaker.
