Chapter 6 Care and Storage
6.1 CLEANING THE OUTSIDE OF THE ENCLOSURE
Wipe the enclosure as needed with a damp cloth. Do not use solvents.
6.2 STORAGE RECOMMENDATIONS
• If you remove the buoy from service seasonally, remove the battery
from the buoy and store separately.
• If the sensor cap will expire before you redeploy the unit, discard the
cap and place a red dust cap over the end of the sensor. If you do
not have a dust cap, just keep the sensor cap on. Do not store the
RDO sensor without adequate protection over the lens.
• When you redeploy the buoy in the spring, use a new sensor cap.
• Replace the desiccant regularly.
6.3 CLEANING SYSTEM MAINTENANCE
6.3.1 Maintaining the Rotating Brush
A rotating brush removes contaminants and biofouling from the
sensors. Periodically check the brush for cleanliness and contact with
the sensor cap. For optimum performance, the brush should lightly
sweep the sensor cap. Adjust the contact by loosening the clamp that
holds the probe, then move the probe toward or away from the brush.
The brush itself may be raised or lowered by loosening the set screw in
the brush itself. The brush may also be rotated 180° by removing it
from the shaft and turning it over.
6.3.2 Maintaining the Cleaner Shaft
The cleaner shaft is connected to the motor shaft with a flexible
coupler made of rubber hose that is secured with stainless hose
clamps.
When replacing a cleaner shaft, ensure that the shaft extends through
the bottom of the buoy, but above the chlorine tablet. Adjust the shaft
length by varying the depth of the shaft in the flexible coupling. Also
ensure that the coupler clamps do not hit the motor mounting screws.
6.3.3 Maintaining the Chlorine/Bromine Tablet Chamber
The cleaner assembly includes a chamber in the bottom of the down
tube that holds a 3" chlorine or bromine tablet. These tablets will
slowly dissolve to reduce algae and other organic growth on the probe.
The tablets dissolve at varying rates depending on environmental
