NOTE:

Blower kits are not

thermostatically controlled.

The heater and blower kits described in this manual are intended to work with the EHX*E
Series of non-pressurized, explosion-proof camera enclosures.

When installing heater and blower kits in EHX*E Series explosion-proof camera enclosures,
the maximum camera and lens sizes are reduced depending on the size of the blower, heater
brackets, and PC board(s). Before installing the heater and blower kit, verify that the camera
currently installed in the enclosure will fit in the enclosure after installation of the accessories
(refer to the

section. Do the following to install

5. Attach the PC board bracket to the enclosure’s rear plate using the hardware provided
(refer to Figure 1 or 2).

6. Attach the heater bracket to the front of the camera sled using the hardware provided
(refer to Figure 3 or 4).

7. Reinstall the camera and camera sled, but do not tighten the set screw that holds the
sled in place.

8. Attach the video cable to the camera.

9. Reconnect the heater wires to the PC board (refer to Figure 8).

10. 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.

11. 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.

12. Tighten the set screw that holds the camera sled in place.

13. Reinstall the rear plate of the enclosure. Apply Loctite® 222 low-strength thread locker
(not supplied) to the screws to prevent them from seizing.
