Carrier 50RLP Installation, Aquazone System Control Panel Inputs and Outputs

INSTALLATION

Inspection — Inspect the package contents for visual de- fects that may have occurred during shipping. If there is any damage, contact your local representative before proceeding.

Mounting Location — The Aquazone™ system control panel should be located indoors. Be sure the location prevents moisture and rain from coming into contact with the internal hardware. Avoid areas where excessive moisture, corrosive fumes, or vapors are present. The ambient temperature range at the location should be between 32 to 125 F. Do not install the Aquazone system control panel in electrical interference or high radio frequency areas. Select a location which will be safe from water damage and allow sufficient access for service and

wiring. For proper service of the Aquazone system control panel, the following service clearances are recommended:

Height: 54 in.

Width: 42 in.

Depth: 36 in.

Mounting — Mount the Aquazone system control panel to a wall with screws or bolts (not provided). Attach through the mounting holes provided in enclosure. Provide clearance to open key-locked access door. Refer to the mounting sheet in- cluded with the Aquazone system control panel for additional detailed mounting instructions.

Wiring — The Aquazone System Control Panel inputs and outputs are shown in Table 2.
