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.
