Repair Procedure
CAUTION: READ THROUGH ALL OF THESE INSTRUCTIONS,
INCLUDING THE NOTICE AND WARNINGS ON THE LAST
PAGE OF THIS SHEET, BEFORE BEGINNING ANY DISASSEM-
BLY OR REPAIR.
NOTE:Repairs must be performed in a clean area. Hands,
clothing, tools and work area must be completely free of oil,
grease and foreign matter to prevent contamination of component
parts and valves.
NOTE:Before beginning relief valve removal or inspection, be
sure protective eyewear and gloves are worn. Never look directly
into the relief valves at any time because they may discharge and
cause bodily injury.
Removing Relief Valves from Manifold Assembly
1. EVACUATE ALL GAS FROM THE SYSTEM BEFORE ANY
DISASSEMBLY OR REPAIR.
2. Turn the positioning handwheel so that arrow on the manifold
body located directly below the handwheel is positioned
midway between any two adjacent numbers on the handwheel.
3. Turn the knob of each bleeder valve in a clockwise
direction. This should allow any remaining vapor to bleed
from the hole in bleeder valve body. After the discharge has
stopped, the relief valves are ready to be removed.
4. Remove the weep hole deflectors from the relief valves with
an appropriate wrench. This will provide clearance and a grip
for removing relief valves. See Figure 1.
5. Remove safety relief valves from top of manifold assembly by
turning valves counter-clockwise. Relief valves may be removed
using an open end wrench, monkey wrench, pipe
wrench, or chain wrench applied to the hex section of the
relief valve. Save valves for reassembly.
NOTE: In some cases, it may be necessary to remove the
positioning handwheel to facilitate removal of relief valves one
and four. If this is done, carefully note position of the handwheel
and replace it in exactly the same position. Position can be
verified by matching the number of the closed port with the
number on the handwheel and the arrow stamped on the
manifold body pad directly below the handwheel.

Removing Manifold Assembly from Container
The manifold assembly may be removed from the container to
continue repairs. The manifold assembly does not have to be
removed for repairs.
1. Remove the steel nuts from the steel bolt studs above the
mating flange of the manifold assembly. Nuts are removed by
turning counter-clockwise. See Figure 2. Save nuts and studs
for reassembly.
2. Remove relief valve manifold assembly from the container.
3. Remove gasket located between manifold assembly and
container. Discard gasket.
