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).
