APPENDIX

■Optional Heater Unit WV-CW3H

●Introduction

Installing this heater unit enables the camera to operate under in a low-temperature environment of –30 °C (–22 °F). The heater turns on automatically when the temperature inside the camera drops below +10 °C (50 °F) and turns off when it rises.

A small fan inside the unit will minimize condensation on the surface of the dome cover caused by changes in ambi- ent temperature unless temperatures change too rapidly. The fan will stop when there is no possibility of condensa- tion.

●Precautions

•This product should be installed and connected by qualified service personnel or system installers.

•Do not use the same 24 V AC power source supplying the power to the camera for the heater unit. Connect anoth- er 24 V AC power source to the heater unit. If the same power source is used, turning the heater on and off may disturb the camera images.

•When servicing, pay attention to high temperature on the surface of the unit. Disconnect the harness and wait until it cools.

•When you install the camera in a low-temperature location and start operating it, it may take time (around 30 min- utes) for the inside of the camera to warm up. Cut power once then supply power again.
