Individual Components
DCM2 Controller Enclosure Mounting
•
Locate an area on a vertical wall where the controller can me mounted at approximately eye level and
have enough clearance to allow the DGMa modular sensor housing to be installed near and below the
controller. Avoid outdoor installations, especially in direct sunlight. The location of the DGMa sensor
housing must have about 18” of clearance above it to allow removal of the sensors, and about 12
inches below to access water sample petcock and a sample cup.
NOTE: a common mistake made at installation, is not allowing enough space above the sensor housing
to accommodate routine sensor maintenance.
•
Individual DCM2 controllers
are shipped with mounting
bracket (4) and mounting
screws (1) to assist with wall
mount installation.
•
Disconnect the bracket from
the back of the enclosure by
pressing the black plastic
release clip (4) at the
bottom, and slide the
enclosure down towards the
clip, then tip the bracket off
the back of the enclosure.
The wall mounting bracket
can then be used as a
drilling template as shown.
•
Mount the bracket on a
vertical wall at approximately
eye level, within 30 in. of the
nearest 120VAC power
outlet. Alternatively, mount
near a power disconnect,
and wire the power directly
to the controller through
electrical conduit. Conduit
adaptor fittings are available
from ProMinent. Refer to local and national electrical codes for wet locations.
•
Fasten enclosure securely to the bracket as shown, by hanging enclosure on the bracket, pushing
the enclosure against wall and lifting until the enclosure snaps securely to the bracket.
•
After controller is mounted, time is best used mounting the DGMa modular sensor housing to
allow sensors to equilibrate while the remainder of the installation, wiring and configuration is
performed.
