HEATER KIT AND BLOWER KIT INSTALLATION
Do the following to install both the heater and blower kits:
1. Disconnect all sources of power from the enclosure.
2. Remove the enclosure’s rear plate with a 5 mm Allen wrench.
3. Remove the camera sled and camera from the enclosure.
a. Use a 3/16-inch Allen wrench to loosen the set screw that holds the camera sled
in place.
b. Partially pull the camera sled out; disconnect the camera’s power wires and video
cable.
c. Remove the camera sled from the enclosure.
d. Remove the camera from the sled.
4. Disconnect the heater wires from the PC board.
5. Remove the blower from the bracket; keep the hardware attaching the blower to the
bracket and discard the bracket.
6. Attach the blower to the bracket on which the PC board for the heater is attached.
7. Attach the PC board and blower bracket to the enclosure’s rear cover the hardware
provided (refer to Figures 1 and 2).
8. Attach the heater bracket to the front of the camera sled using the hardware provided
(refer to Figures 3 and 4).
9. Reinstall the camera and sled; do not tighten the set screw that holds the sled in place.
10. Attach the video cable to the camera.
11. Reconnect the heater wires to the PC board (refer to Figure 8).
12. If the camera uses a different voltage than the heater, reconnect the power wires to
the camera. If the camera uses the same voltage as the heater, proceed to the next step.
13. Bring power wires through the rear plate and connect the wires to the PC board (refer
to Figure 8). If you are installing the HKX4-2, HKX6-2, or HKX8/10-2 heater kit, refer to
Table A, 24 VAC Wiring Distances. If the camera uses the same voltage as the heater,
the camera power consumption must be considered when determining the wire gauge.
Table A does not include camera power because of the many variations.
14. Tighten the set screw that holds the camera sled in place.
15. Reinstall the rear plate of the enclosure. Apply Loctite
