6) Re-Install Dome Cover a) Place the dome cover on the housing base. b) Push the cover lightly onto the base, rotate the liner or dome cover to align with lens and tighten the 3 tamper resistant set screws (see FIGURE 1) until the cover seals tight against the housing base. CAUTION: Do Not Over Tighten! Changing the Polycarbonate Dome The ZC-OH5 housing is supplied with a clear dome and black plastic liner. If damaged, the dome can be replaced by removing the 4 flat head screws inside the dome cover. Due to a tight seal, some pressure may be required to the top of the dome to break the seal. After installing the new dome, replace the retaining ring and tighten the 4 flat head screws until the retaining ring is flush with the adjacent surface. MAINTENANCE NOTES If the housing cover is opened frequently or if the O-Ring dries out, apply a light coat of good quality silicone based grease to the O-Ring to maintain a watertight seal. Replacement O-rings and other replacement parts are available through CBC (AMERICA) Corp. OPTIONS 1. Pendant Mount A pendant mount adapter is available for applications that require the dome to be dropped from the ceiling from a pipe. The pendant mount adapter accepts a 1" NPT pipe thread (Model ZC5-PM2). 2. Wall Mount The wall mount combines the pendant mount with a wall mount bracket for various wall-mounting applications (Model ZC5-WM2). 3. Heater A 24VAC heater option is available. Contact CBC (AMERICA) Corp. for details and specifications. 4. Housing Color Different housing colors (either painted or anodized) are available for a minimum order lot and custom paint charge. 6
