Setup Procedure

Important Notes:

Regardless of the conditions, the X-Purge option is
designed to automatically withhold power to the pro-
tected enclosure while inducing Rapid Exchanger, for
at least five minutes. Normal exchange times should
be doubled if large obstructions block inert gas flow.
To test the vent's operation, gently prod the vent flap-
per open with a soft pointed object, such as the eraser
end of a pencil, to ensure that the vent valve works
freely. On vertically configured vents, this can be
accomplished from within the protected enclosure.
Side mounted –90 configured vents can be tested by
removing the pipe plug at the bottom of the mounting
tee. Multiple operations require only one test per day if
the enclosure is not opened or left unattended.

The volume exchange rate is based on a four enclo-
sure volume exchange.
The Startup Instruction Nameplate Exchange Time Slot
will feature the standard factor for this system "ONE
MINUTE PER CUBIC FOOT", but the unit may feature
a set of direct factor nameplates with self adhesive
backing such as "TEN MINUTES", for application to the
start-up instructions, dependent on how the system
was specified and purchased. Field modification of this
nameplate, to show a direct factor, is acceptable as
noted above if the method used to mark the nameplate
does not deface the instructions listed. Materials used
for the marking must be indelible and withstand prevail-
ing environmental conditions.
