Filter Unpacking, Installation, Storage, and Operation (cont’d)
Installation
• Carefully lift the filter into place, inserting it into the housing and taking care to make certain the
knife edge is properly seated into the fluid gel seal. NOTE: Setting filters properly requires two (2)
people.
• Rotate each of the four (4) filter retainers, one (1) in each corner, into place and hand-tighten the
hex nuts.
• Install the grille using the four (4) acorn nuts or ¼-turn fasteners [haven’t mentioned this ¼-turn
fasteners option previously] with the hinged grille option.
Storage
• Location: Storage should be indoors, (under roof and enclosed) and absolutely protected from
moisture.
• It is strongly recommended that the storage space be climate-controlled.
- Temperature Limits: Maximum temperatures of 250°F (121°C) intermittent, and 100°F (38°C)
steady state. Minimum temperature is 32°F (0°C).
Operating Conditions
• Temperature: The maximum operating temperature is determined by the filter configuration.
- Consult the filter submittal drawing for the specific maximum operating temperature.
• Humidity: 100% relative humidity is acceptable. However, condensation must be avoided to
prevent degradation of performance and potential filter failure.
• Filters should not be operated in caustic or acidic environments.
• Filters should not be operated in excess of twice the rated performance for flow rate or pressure
drop.
Static Pressure/Upstream Aerosol Ports
Filter must be supplied with centerboard and port to sample upstream aerosol and to measure
upstream static pressure. A filter with centerboard and port is also necessary to access damper
adjustment (filters ordered separately).
