5. Remove the bonnet by turning it counter-clockwise.
Carefully slide it off the end of the stem. Save for reassembly.
6. Slide the packing out from the inside of the bonnet.
Remove and discard. Remove the bonnet gasket from the
back of the bonnet and discard.
NOTE: The bonnet gasket may be lodged on the machined
surface inside the manifold body.
7. Remove the washer located behind the bonnet by sliding it
over the end of the stem. Discard.
8. Clean and wash all threads and surfaces on the bonnet
thoroughly.
Reassembly:
1. Slip new washer over stem and slide it down until it contacts
the retaining ring.
2. After applying a light coating of grease or anti-seize lubricant
to the stem and bonnet cap gasket, stick the bonnet cap
gasket to the sealing surface on the bonnet.
3. Apply a thread locking compound to the main threads on
the bonnet. Slide the bonnet down the stem and tighten.
4. Install new packing by sliding it down the stem and into the
bonnet.
5. Slide gland onto the stem and tighten using a 9 /16" wrench.
6. Insert new Woodruff Key into the slot on the end of the stem.
7. Slide handle assembly down the stem unit it is centered over
the Woodruff Key.
8. Secure handle to the stem by installing new set screw and
tightening.
9. Work the handle back and forth several times for even
distribution of lubrication.
NOTE • If the handle is too tight and will not move, loosen the
gland until handle moves with a fair amount of ease.
See Step 5.
• If the handle moves too freely, it is an indication that
the gland is too loose. The gland must be tightened
or it will leak.
Re-Installing the Manifold Assembly
If the manifold was removed from the container, replace with the
following steps:
1. Apply a suitable non-hardening pipe compound to the male
threads of the lower manifold body.
NOTE: Do not apply compound to the female threads in the
container coupling.
2. Thread the manifold into the container port hand tight.
3. Using an appropriate wrench applied directly to the lower
body of the manifold, tighten the manifold into the container
with a sufficient torque to provide a leak tight seal.
Relief Valve Replacement
1. Apply a small amount of a suitable non-hardening pipe
compound to the male threads of the relief valves.
NOTE: Do not apply compound to the female threads in the
manifold port.
2. Thread relief valves into manifold assembly hand tight.
3. Using an appropriate wrench on the hex section of the relief
valves only, screw valves in approximately 1 1 /2 additional
turns. Tighten valves with a sufficient torque to provide a
leak-tight seal.
Placing Relief Valve Manifold Back into Service
Turn the knob of each bleeder valve counterclockwise until it is
fully back-seated. See Figure 2. During normal operation, the
bleeder valve should be left in this position.
During normal operation, with the relief valves properly in place,
the positioning handle should be kept at the center stop
position. In this position, both relief valves are open to the
container vapor space, providing extra relief capacity by
permitting both valves to function simultaneously if necessary.
Check the connection of the replaced relief valves and manifold
using a high quality leak detection solution. If bubbles appear,
there is a leak. The connection must be leak tight.
