5. Remove the push plate hex head bolt and remove the push plate.
6. Start from the bottom, pull the black closure strip away from the flanged covers (past
the segmentation lines) exposing the eyewash and drench hose assembly covers.
The overlay is required to maintain a moisture proof barrier.
7. Pull the covers out and away from the eyewash over the ball valve extension. Should
the black grommets drop out of the covers reinsert the grommets after the covers are
pulled off the shower.
CAUTION: Be careful in the next step and do not cut the heat trace cable.
8. With a suitable knife, remove the neoprene insulation self- adhering seal strip.
9. Pull back the insulation. The insulation can be reused if it is removed undamaged.
10. If the valve packing requires adjustment, it may be done at this time.
11. To remove the ball valve, do the following:
a. Use a knife to cut the fiberglass bonding tape that holds the heat trace cable to
valve and pipe. Be careful; do not cut the outer jacket of the heat trace cable.
b. Pull the heat trace cable over the end of the elbow and lay cable away from pipe.
c. The valve can now be removed for inspection and repair as required. For more
information, see “4.5 Ball Valves” on page 4-5.
To re-assemble the eyewash and drench hose:
1. Replace the heat trace cable in reverse order of removal. Ensure the cable does not
interfere with the ball valve extension or the stops on the valve body.
2. Replace the fiberglass-bonding tape. Ensure there is as much physical contact
(cable to pipe) as possible. Fiberglass cloth tape is recommended. Do not use
electrical or duct tape.
3. Reinstall the neoprene insulation and tape insulation closed. Ensure there are no
exposed metal parts. Ensure the insulation does not impede valve closure.
4. Reinstall the covers. Install the top cover first by sliding one half of the cover up and
then over the ball valve extension and eyewash nipple.
5. Reinstall the black seal strip on front and back of shower. Seal strip can be adjusted
by crimping with pliers if too loose (prior to attachment to covers), or separated if too
tight, by inserting screwdriver and opening up seal strip.
