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.
