DISASSEMBLY

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

1.Disconnect the power from the enclosure.

2.Remove the mating connector from the rear of the enclosure by turning the outer ring counterclockwise until a click is felt; then pull the mating portion of the connector off. You may elect to remove the enclosure from its mount, which will make the disassembly process much easier.

3.Remove the center cap from the Schraeder valve. Refer to Figure 1.

4.Relieve internal enclosure pressure by depressing and holding down the center stem of the Schraeder valve.

5.Remove the rear plate of the enclosure. Refer to Figure 1 and do the following:

a.Remove the spiral retaining ring from the back of the enclosure. Use a screwdriver to pry the end of the spiral retaining ring from the retaining ring groove.

b.Pull on the T-handle to remove the rear plate from the housing.

RECHARGING AND REASSEMBLY

Whenever the enclosure is disassembled for servicing, it should be recharged after reassembly and prior to installation. Recharging requires the use of a Pelco EH8000RKIT recharge kit (or equivalent) and O-ring kit, part number EH8006ORKIT.

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

1.Once the enclosure has been disassembled, remove the O-ring from the rear plate and install a new O-ring in the O-ring groove 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 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 back into the body making sure the front lip of the sled is under the retaining bracket of the enclosure. When fully installed, the rear plate will fit firmly into the rear opening of the housing and the retaining groove will be fully visible.

4.Reinstall the spiral retaining ring in the retaining groove in the rear of the enclosure.

5.Recharge the enclosure. Refer to the section Recharging and Reassembly for instructions.
