EQUIPMENT INSTALLATION
6.0 INSTALLATION
The PET-820 was designed for wall mount installation. The enclosure is water resistance and provides conduit connections
for the wiring. This section will detail all necessary connection and mounting precautions.
6.1 PLANNING THE INSTALLATION
The first step in the installation is planning the job. Programming can be minimized by analyzing the job requirements and
comparing these with the factory default settings. Use "APPENDIX B" to aide in the system design. Use this guide to decide
what characteristics you want for each loop circuit and how the overall system shall respond. Before making connections,
draw a rough sketch of the individual circuits and how they may operate.
6.2 INSTALLATION CONSIDERATIONS
Avoid installing the PET-820 in the following places. Doing so may result in malfunction or noise to the system.
1. In direct sunlight and hot, cold or humid places. The temperature range should be from 32 degrees Fahrenheit to
110 degrees Fahrenheit.
2. Sulfuric gases produced in areas where there are thermal springs, etc. may damage the equipment or contacts.
3. Places in which shock or vibration are frequent or strong.
4. Near high frequency electronic welders.
5. Near radio broadcast antennas.
6. Install at least 8 ft. from radios and televisions.
6.3 MOUNTING
The wall where the PET-820 is to be mounted, must be able to support the weight of the PET-820. If screws other than the
ones supplied are used, make sure to use the same size screws as supplied with the system.
Three mounting holes are provided in the PET-820 enclosure. Top center has a sealing plug provided. The lower two holes
are isolated for improved sealing.
6.3.1 TO WALL MOUNT
1. Place the template (included in "Appendix-D") on the wall and mark the three screw positions.
2. Install the top middle screw so that the head is 1/16" to 1/8" from the wall.
3. Remove the terminal cover, this is the lower cover that is held on by two screws. Hook the PET-820 on the first
screw already installed.
4. Finish mounting the PET-820, using the lower two holes on the left and right side of the terminal compartment.
