SSC-5000 User Manual September 21, 200496. Once the retaining ring has been completely disengaged from the housing, grasp the housingin one hand and the rear end cap assembly in the other hand and carefully pull them awayfrom each other.Closing the Housing:When closing the housing it is very important that no moisture be internally trapped. Moisturecan, and most likely will, condense during deployment, causing the lens to fog and degrade theinternal elements. We recommend either of the following two procedures for eliminatingmoisture from the camera and housing before closure.1. Nitrogen purging. If compressed nitrogen is available it is a simple matter to purge thecamera and pressure vessel as the last action prior to closure. Deliver the nitrogen at low-pressure (10 psi) using a needle tip fitting. The camera should be placed as far into thehousing as possible but allowing enough room to insert the needle valve to deliver thenitrogen. Flood the housing with nitrogen until the entire air volume of the housing has beenreplaced (20 seconds is probably more than sufficient). Immediately close the housing.2. Heat purging. Put the camera and housing on heat insulated material and place into a 50°C(120°F) oven for 60 minutes. Remove, assemble and immediately close.If neither of the first two procedures is possible, as a last resort, use a "blow dryer" (for dryinghair) set on "warm"/"medium" (do not set to "hot"/"high"). Fan the camera and housingthoroughly for 15 minutes. Assemble and immediately close.Assembly:1. Prepare a clean and stable work area.2. Inspect and clean all o-rings and sealing areas of the housing and end cap.3. Lubricate o-rings with Dow Corning DC-4 or DC-111 (or equivalent) silicone lubricant ifnecessary.4. Bake camera internals and housing at 120 degrees Fahrenheit for one hour. If an oven is notavailable be sure to purge housing with dry air or nitrogen prior to assembly.5. Replace desiccants.6. Align camera internals with housing and gently slide camera into housing.7. Once retaining ring has been tightened by hand snug it down with the spanner wrench.MaintenanceThe SSC-5000® requires very little maintenance. Following are some procedures for keepingyour camera in good condition.Post Dive Check Out:1. Thoroughly rinse the cable and camera with fresh water.2. Dry the camera with a clean cotton towel.3. Inspect the port for cracks and contaminants. If cracked treat as if the housing has beenflooded. Follow the emergency flooding instructions.4. Inspect for scratches and gouges on the housing.It's always a good idea to test your camera before redeployment.
