4.5 SUN SHROUD INSTALLATION
5.1 SYSTEM TEST
The sun shroud provides an air space between
itself and the enclosure to protect the enclosure
from the direct rays of the sun and reduces the
internal temperature of the enclosure approximately 10-15° F (-12.22°-9.44° C).
To install the sun shroud, perform the following
steps (see Figure 9):
1. Insert the mounting straps through the holes
in the standoffs inside the shroud.
2. Align the sun shroud.
3. Fasten the mounting straps securely around
the enclosure.
5.0 OPERATION
To ensure proper operation, the unit should be
installed as previously stated and wired in accordance with Figures 7 and 8.
1. Power up the camera.
2. Check the operation of the lens functions such
as focus, zoom, and iris.
6.0 TROUBLESHOOTING GUIDELINES
1. Once the camera has been powered up and
no picture is present on the monitor, take the
following steps:
a. Verify that the video monitor has been
properly terminated.
b. If the monitor is properly terminated, open
and close the iris to see if a picture appears.
c. If adjusting the iris does not yield a pic-
ture, check the camera for proper voltage.
d. If the above do not restore a picture, con-
tact Pelco’ s T echnical Assistance Program
(TAP) at 1-800-289-9100.
7.0 MAINTENANCE
At a minimum frequency of once each year, the
enclosure should be routinely recharged. Additionally, if the enclosure must be opened for servicing,
the enclosure would also need to be recharged.
The following instructions explain how to disassemble the enclosure, reassemble and charge it.
7.1 ENCLOSURE DISASSEMBLY
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. (See Figure 10, item 6).
4. Relieve internal enclosure pressure by de
pressing and holding down the center stem of
the Schraeder valve. (See Figure 10, item 6).

Installation
10Pelco Manual C418M (8/97)
Page 13
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 retaining ring groove in the enclosure body.
6. Next, pull on the “T” handle to remove rear
plate from housing. If necessary, use a screwdriver 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 servicing, it should be recharged after reassembly
and prior to installation.
Recharging requires the use of a Pelco
EH8000RKIT recharge kit (or equivalent) and applicable 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 Oring 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.
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 pressure to the enclosure by affixing the tire chuck
to the Schraeder valve on the rear of the enclosure. You must remove the Schraeder valv e
cap first.
4. Remove the plastic cap on the pressure relief 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 registers the lowest humidity level (changing color
from green/blue to pink). The humidity indicator can be viewed through the front window of the enclosure looking at the inside top
of the enclosure. Once the humidity indicator 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 v alve cap . Also ,
replace the plastic cap on the pressure relief
valve. The enclosure is ready for service.
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 instructions.
