Steel surfaces of equipment including reciprocating, helical rotary,
scroll, air cooled water chillers, and air-cooled, remote-type condensers,
that do not have a zinc coating conforming to [ASTM A 123/A 123M] [ASTM A
653/A 653M], or a duplex coating of zinc and paint, shall be provided with
a factory applied coating or paint system. Thickness of coating or paint
system on the actual equipment shall be identical to that on the salt-spray
test specimens with respect to materials, conditions of application, and
dry film thickness.

SOURCE QUALITY CONTROL
2.11.1
Salt-Spray Tests
Factory-applied coating or paint system on equipment located outdoors
including reciprocating, helical rotary, scroll, air-cooled water chillers,
and air-cooled remote-type condensers, shall be factory salt-spray tested
in accordance with ASTM B 117. Period of test shall be 500 hours. Test
specimens shall have a standard scribe mark as defined in ASTM D 1654.
Upon completion of exposure, coating or paint system shall be evaluated and
rated in accordance with procedures A and B of ASTM D 1654. Rating of
failure at the scribe mark shall be not less than six (average creepage not
greater than 3 mm 1/8 inch). Rating of the unscribed area shall not be
less than 10 (no failure).
PART 3
EXECUTION
3.1
INSTALLATION
Installation procedures shall conform to ASHRAE 15, and manufacturer's
recommendations. Refrigerant safety relief devices shall have discharge
piped to building exterior. Interlock compressor operation with the
chilled [and condenser] water pump starters, so that compressors cannot
operate unless the pumps are operating. Make piping connections to
equipment after piping systems have been tested and cleaned.
3.2
FOUNDATIONS
Foundations for mounting of equipment, accessories, appurtenances, piping,
and controls shall be provided, including supports, vibration isolators,
stands, guides, anchors, clamps, and brackets. Anchor bolts and sleeves
