3.0 INSTALLATION To install the window and heater kit, perform the following steps:
1. Turn off power to the enclosure.
2. Disassemble the enclosure by performing the following steps:
a. Loosen the sled assembly from the housing by unscrewing the two screws
connecting the rear plate to the housing.
b. Pull on the “T” handle and slide the camera sled out of the housing and
stop approximately three inches from completely removing the camera
sled. Always use care when removing the camera sled from the EH2500
Series housing.
c. Disconnect the heater wiring connectors. Damage to the heater wires
may occur if the sled is pulled out too far before the wiring connectors are
separated.
d. Remove the camera sled and examine the rear O-ring for wear. If you
notice wear, order the EH25/8104ORKIT O-ring kit. Set the camera sled
aside.
3. Unscrew the two screws connecting the viewing window to the housing and
set aside.
4. Remove the viewing window and set aside. This may be done by inserting a
long screwdriver or other long object into the enclosure and pushing it out. Do
not push on the viewing window edge, as the screwdriver may slip and dam-
age the O-ring. (This is an acceptable procedure when you are going to dis-
pose of the viewing window. Use care when removing a viewing window that
you want to keep.)
NOTE:
Be sure enclosure power
is turned off before working on the
enclosure.
NOTE:
Always use care when re-
moving the camera sled from the
EH2500 Series housing. Pull the
sled out sufficiently enough to dis-
connect the heater wiring connec-
tor. Damage to the heater wires
may occur if the sled is pulled out
too far before the wiring connector
is separated.
