Enclosure Servicing, Recharging the Enclosure

CAUTION: Pressure must be released prior to opening the enclosure or personal injury may result.

5.Once the internal pressure has been relieved, use a screwdriver to pry the end of the spiral retaining ring (Figure 10, item 5) from the re- taining ring groove in the enclosure body.

6.Next, pull on the “T” handle to remove rear plate from housing. If necessary, use a screw- driver and brace against the hex portion of the filler valve on the rear plate; grab the “T” handle and work back and forth to remove rear plate.

7.2 ENCLOSURE SERVICING

Whenever the enclosure is disassembled for ser- vicing, it should be recharged after reassembly and prior to installation.

Recharging requires the use of a Pelco EH8000RKIT recharge kit (or equivalent) and ap- plicable O-ring kit, part # EH8004ORKIT, EH8006ORKIT or EH8008ORKIT.

To prepare the enclosure for recharging, follow the steps below.

1.Once the enclosure has been disassembled as mentioned above, remove the O-ring from the rear plate (Figure 10, item 12) and install a new O-ring in the O-ring grove in the rear plate.

2.When the new O-ring has been installed in the rear plate, smear a liberal amount of the O-ring lubricant provided with the EH8000 O- ring kit on the exterior surface of the O-ring and rear plate. Replace the desiccant bag in the enclosure with a new one provided with the kit.

3.Slide the camera sled (Figure 10, item 11) back into the body (Figure 10, item 10) making sure the front lip of the sled is under the retaining bracket of the enclosure. When fully installed, the rear plate (Figure 10, item 12) will fit firmly into the rear opening of the housing and the retaining grove will be fully visible.

4.Reinstall the spiral retaining ring (Figure 10, item 5) in the retaining grove in the rear of the enclosure.

5.Proceed to Section 7.3 for recharging instruc- tions.

7.3 RECHARGING THE ENCLOSURE

WARNING!Prior to recharging, make sure the regulator is preset to a pressure not exceeding 5 lbs.

Exceeding 5 lbs will damage the enclosure.

1.Pressurize the inside of the enclosure using the EH8000RKIT recharge kit only. Connect the regulator to the tank by threading the nut into the socket of the tank valve and tighten with a wrench. This regulator is factory preset for 5 PSI. Do not attempt to readjust the regulator.

Note: Before turning tank valve on, be sure that regulator valve is totally open.

2.Once the regulator has been secured to the tank, open the tank valve.

3.Using the self-holding tire chuck, apply pres- sure to the enclosure by affixing the tire chuck to the Schraeder valve on the rear of the en- closure.You must remove the Schraeder valve cap first.

4.Remove the plastic cap on the pressure re- lief valve on the rear of the enclosure. Using a small screwdriver to hold it open. At this point, allow the nitrogen to flow through the enclosure until the humidity indicator regis- ters the lowest humidity level (changing color from green/blue to pink). The humidity indi- cator can be viewed through the front win- dow of the enclosure looking at the inside top of the enclosure. Once the humidity indica- tor registers the lowest level, remove the screwdriver and allow nitrogen to continue to flow into the enclosure until you no longer hear the flow of nitrogen from the tank to the enclosure.

Hint: Having the window of the enclosure point up toward the sky will greatly reduce the

purge time necessary to remove oxygen from the enclosure.

5.Remove the tire chuck from the Schraeder valve and apply the Schraeder valve cap. Also, replace the plastic cap on the pressure relief valve. The enclosure is ready for service.
