SERIES 54000
Spring Loaded Pressure Vent
INSTALLATION PROCEDURE:
1.
Unpack unit. Inspect carefully to make sure that all
packing material, protective cardboard, tape and flange
protectors are removed.
2.
The vent should be lifted by the multiple lifting lugs only.
Do not lift by attachment to weatherhood or flange. Care
should be taken to avoid damage to unit as it is being
positioned in its mounting location.
3.
The vent setting is established at the factory per order
specifications. No modifications or adjustments are
required prior to vent installation.
4.
Mount vent to the appropriate flange using gaskets
compatible with service conditions. For best perform-
ance, the vent should be mounted level so that the seat-
ing surface is no more than 1° off horizontal.
MAINTENANCE:
Protectoseal recommends that our products be inspected and
maintained according to the normal maintenance schedule of
the facility. At a minimum, maintenance should be conducted
annually. More frequent maintenance may be required, and
should be scheduled, for unusual service conditions.
CAUTION: When maintaining any Protectoseal
device, the legal, corporate and advisory safety
regulations and procedures appropriate for the
specific installation site must be fully understood
and followed.
CAUTION: Tank vapor space pressure or vacuum
should be relieved before any maintenance
operations are undertaken.
MAINTENANCE PROCEDURE:
1.
Remove the lifting lugs from the studs. Remove hood
nuts and weatherhood from vent. Remove the screen.
NOTE: No spring forces are involved during these
processes.
2.
Inspect vent and remove any loose dirt or foreign
material from the unit or the hood. Inspect the screen
and replace if damaged.
3.
The vent is designed so that all spring forces are
contained by the spring package. The springs are com-
pressed between the flange plate and upper spring
guides (see Detail A).
WARNING: If it is necessary to disassemble
the spring package, extreme caution must be
exercised due to the high spring forces that
may be present within the spring package
assembly.
