2.1Installation Considerations

The Liqui-tect panel must be installed indoors and may be mounted on the surface of a wall or flush- mounted, depending on the user’s application and the type of wall the unit will be mounted on. The unit’s location must meet the following criteria:

•The panel must be placed close enough to the areas to be monitored to permit proper connection of the leak detection cable. The panel will monitor two zones; each zone can accommodate up to 5,000 ft. (1524m) of leak detection cable.

•The Liqui-tect panel should be mounted where it can be easily accessed. Personnel would access the unit through the LCD on its front cover or through SiteScan.

•The site also must have electrical service and must permit connection of the panel’s four digital outputs, two inputs for leak detection cables and two analog outputs for connecting to a building management system or external alarm.

•The wall material must be capable of supporting the weight of the Liqui-tect panel: see 7.0 - Specifications.

NOTE

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

2.1.1Unpacking and Preliminary Inspection

•Before unpacking the Liqui-tect panel, inspect the shipping carton for damage or signs of mishan- dling, such as gashes or holes in the carton or severely flattened corners.

•Open the shipping container carefully. Use care to avoid puncturing the container with sharp objects that might damage the contents.

•Inspect the Liqui-tect panel and all included components for damage.

•If any damage from shipping or mishandling is observed, immediately file a damage claim with the shipping agency and forward a copy to:
