FILTER UNPACKING, INSTALLATION, STORAGE AND OPERATION
(CONTINUED)
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.
Aerosol Injection and Static Pressure/Upstream Aerosol Ports
The AstroFan
™
EC FFU RSR is supplied with room-side aerosol injection port and aerosol dispersion
system as well as an upstream static pressure/upstream aerosol sample port to facilitate validation
testing. These ports are available standard as 3/8" female NPT fittings, supplied with respective plugs.
These connection points are labeled on the inside surface of the housing and are visible from the
room side.
To remove grille:
1. Loosen and remove the acorn nuts and flat washers.
2. Carefully remove and lower the grille. To avoid potential injury, it is strongly recommended two
people perform this task.
To replace grille:
1. Align the holes in the grille with the studs.
2. Hold the grille in place and reinstall the flat washers and acorn nuts. To avoid potential injury, it
is strongly recommended two people perform this task.
3. Hand-tighten the acorn nuts. Do not use a wrench or socket, as overtightening may damage
the threaded connection.
