Sealing Surface Protector
▲
WARNING
The sealing surface protector must be
removed before the 2100 Series is returned
to service. The vent will not seal with the
protector in place.
The following instructions are applicable only if the
sealing surface protector was also purchased for your
unit. This guard is available to prevent damage to the
sealing surface when the 2100 Series is being used
for tank access or for running air or weld leads into
the tank.
Remove the sealing surface protector from its bag.
Place one end of the protector over the machined
surface with the legs pointing down and the flat side
up. Firmly press the protector over the sealing surface.
Move around the sealing surface making sure the
protector is snugly attached.

WARNING
Ensure the tank is at atmospheric pressure
before opening. A pressure buildup inside
the tank can cause a spray to be emitted
from the vent if opened under pressure.
1. Remove the Nylock nut and outer fender washer.
The loop slides off the lanyard attachment
assembly. Remove the lid assembly from the base
and place on a level surface.
2. Loosen the 4 hex nuts on the bottom of the lid
assembly. If the unit is equipped with eyebolts,
insert the screwdriver through the eye to
provide leverage.
