[PART 1 - GENERAL]{.underline}

1.01 [WORK INCLUDED]{.underline}

> This section provides for furnishing and installing fans, including
> centrifugal and propeller types, with all supplemental equipment.

1.02 [RELATED WORK]{.underline}

A. [Division 15 - Mechanical]{.underline}

1\. Vibration Limit and Control, Section 15200.

2\. Ductwork System, Section 15890.

3\. System Component Checkout and Balance, Section 15990.

B. [Division 16 - Electrical]{.underline}. Motors.

1.03 [PERFORMANCE]{.underline}

A. Provide fan type, arrangement, rotation, capacity, size, motor
horsepower, and motor voltage as shown. Fan capacities and
characteristics are scheduled on the drawings.

B. Rate fans according to appropriate Air Moving and Conditioning
Association, Inc. (AWCA), approved test codes and procedures. Supply
fans with sound ratings below the maximums permitted by AMCA standards.
All fans provided must be licensed to bear the Certified Ratings Seal.

C. Statically and dynamically balance all fans.

[PART 2 - PRODUCTS]{.underline}

2.01 [ACCEPTABLE MANUFACTURERS]{.underline}

A. Acme.

B. Greenheck.

C. Penn Ventilator.

D. Hartzell.

2.02 [PROTECTIVE COATINGS]{.underline}

A. [Manufacturer\'s Standard]{.underline}. Apply to all fans, motors and
accessories, the manufacturer\'s standard prime coat and finish, except
on aluminum surfaces or where special coatings are required.

B. [Galvanized]{.underline}. After fabrication of the parts, hot-dip
coat all surfaces which require galvanizing. Where galvanizing is
specified, a zinc coating may be used. After fabrication, apply the zinc
coating and air-dry the coating to 95 percent pure zinc. Acceptable zinc
coatings include Zincilate, Sealube, Amercoat, Diametcoat, or an
approved equal.

2.03 [SUPPLEMENTAL EQUIPMENT]{.underline}

A. [Motor Covers]{.underline}. Provide weatherproof motor covers for
installations out of doors. Apply the same finish as used on the fan.

B. [Belt Drives]{.underline}.

1\. Unless otherwise specified for belt-driven fans, equip the fan
motors with variable pitch sheaves. Select the sheave size for the
approximate midpoint of adjustment and to provide not less than 20
percent speed variation from full open to full closed. Size drives for
150 percent of rated horsepower. Key the fan sheave to the fan shaft.

2\. Nonadjustable motor sheaves may be used for motor sizes over 15
horsepower, at the Contractor\'s option. However, if changing a
nonadjustable sheave becomes necessary to produce the specified
capacity, the change must be made at no additional cost.

3\. Provide belt guards and apply the same finish as used for the fan.

C. [Safety Disconnect Switch]{.underline}. Provide a factory-wired,
safety disconnect switch on each unit equipped with a motor.

D. [Relief Vents and Air Inlets]{.underline}. Provide vents and inlets
with aluminum frames and 1/2-inch mesh, galvanized bird screens. Include
dampers where shown.

E. [Prefabricated Roof Curbs]{.underline}. Furnish prefabricated roof
curbs with built-in cant strips and lined with glass fiber insulation.
Curbs may be made of No. 18 U.S. standard gage galvanized steel or
0.063-inch aluminum. The minimum height is 8 inches. Include on each
roof curb a resilient pad for equipment mounting on the top flange.
