Appendix II: Electronics

Disassembly/Reassembly

1. Remove the titanium end cap and electronics from the housing as follows:

A. Wipe the outside of the end cap and housing dry, being careful to

remove any water at the seam between them.

B. Unscrew the end cap.

C. Pull the end cap and attached electronics out of the housing. Note that

the PCB is electrically connected to the I/O connector.

D. Remove any water from the end cap O-ring and mating surfaces

inside the housing with a lint-free cloth or tissue.

E. Be careful to protect the O-ring from damage or contamination.

2. Reinstall the end cap and electronics in the housing as follows:

A. Remove any water from the O-ring and mating surfaces in the

housing with a lint-free cloth or tissue. Inspect the O-ring and mating

surfaces for dirt, nicks, and cuts. Clean as necessary. Apply a light

coat of O-ring lubricant (Parker Super O Lube) to O-ring and

mating surfaces.

B. Carefully fit the electronics into the housing.

C. Screw the end cap into the housing.

Note:

Before delivery, a desiccant bag is

placed in the housing, and the

electronics chamber is filled with dry

Argon gas. These measures help

prevent condensation.

To ensure proper functioning:

1. Install a new desiccant bag

each time you open the

housing. If a new bag is not

available, see Application

Note 71: Desiccant Use and

Regeneration (drying).

2. If possible, dry gas backfill each

time you open the housing. If you

cannot, wait at least 24 hours

before redeploying, to allow the

desiccant to remove any moisture

from the chamber.
