  2. Photohelic-Type Filter Gage: Graduated to read from 0- to 3.0-inch wg and accurate within 3 percent of full scale range.
  3. Accessories: Static-pressure tips, tubing, gage connections, and mounting bracket.

PART 3 - EXECUTION

3.1  INSTALLATION

  1. Install filter frames according to manufacturer's written instructions.
  2. Position each filter unit with clearance for normal service and maintenance. Anchor filter holding frames to substrate.
  3. Install filters in position to prevent passage of unfiltered air.
  4. Install filter gage static-pressure tips upstream and downstream from filters to measure pressure drop through filter. Mount filter gages on outside of filter housing or filter plenum in an accessible position.
  5. Coordinate filter installations with duct and air-handling unit installations.

3.2  CLEANING

  1. After completing system installation and testing, adjusting, and balancing air-handling and air-distribution systems and clean filter housings. Furnish and install a new set of replacement filters.
