Connecting the sensor cables:
1. Place the sensor cables with the attached glands into the cable ducts
of the housing.
2. Depending on the sensor design, either plug or screw the cable in place.
3. Insert the supplied bushes into ducts that are not in use in order to
seal housing.
4. It is recommended the cable glands in the bottom of the housing be
used for routing the MICRO/2000® and DEOX/2000® sensor cable.
2.3.4 Installing reagent hardware (See Dwg. 50.505.020.010)
WARNING: To avoid possible severe personal injury or equipment
damage, do not service the metering pump while power is applied to the
pump. The motor has enough torque to cause severe pain and injury if
fingers are caught in the pumping mechanism.
WARNING:
To avoid possible severe personal injury or equipment
damage, do not remove the pump occlusion ring while there is any water
pressure at the inlet to the analyser. If the pump occlusion ring is removed
while pressure is applied to the pump, water (possibly containing acid
reagents) can be sprayed from the discharge side of the pump. Sprayed
water may result in damage to the equipment or personal injury as it may
contain some reagent or may be contaminated.
NOTE: It is recommended that water-flow to the wetside should be
blocked and the reagent reservoirs are not filled until installation is
complete. The metering pump may be operated/tested without reagents
or water without damage; however, it is advisable to pour enough water
into the cell to cover the impeller (mixer) before powering the unit to
prevent damage to the impeller shaft seal caused by running the unit dry.
