Operational Information

When fitting a cone to a system, the power to the system should not be

switched on. This prevents any unbalanced-voltage supply damage during

fitting. While cones are not in use, the connector covers must be fitted to

protect from accidental damage to the connector pins. For removing and

fitting a cone to the cone-rod, the following procedures should be observed.

Cone Removal

1. Firstly ensure the power is removed from the system, and

appropriate action is taken to prevent accidental energisation.

2. Remove the four retaining nuts on the black cone support block.

Slide the front half of the support block away from the cone.

3. Holding the cone firmly, unscrew the crossover coupling while

applying light upwards pressure, until it is fully unscrewed. Gently

lower it until the connector is accessible, and then ease the

connector from the cone. Note that there is only approximately

40mm of free wire inside the end of the cone-rod, and attempting to

pull the cable out too far can damage the cable.

4. Refit the cone’s connector cover, and place it in a transit case for

safety.

Cone Fitting

1. Remove the cone from the transit case, making note of the serial

number on the end of the cone body. This is important to ensure

that when the system is operated, the automatic cone selection

function can be verified.

2. Remove the connector cover, and store in the transit case. Check

that the o-ring on the back of the cone is in good condition. Gently

pull the small connector from the end of the cone-rod, taking care

not to pull the wire out too far.

3. Orientate the male and female pins on the cone rod connector and

the cone connector, and push the two connectors together. Gently

push the cone up until the threads of the cone, crossover and cone-

rod touch.

4. Applying light pressure upwards, rotate the crossover to draw the

rod and cone together.

5. Replace the cone support block

Where a cone is disassembled, all the o-rings should be replaced with new

ones. It is recommended to use a small amount of silicone grease on all o-

rings during assembly. It is of utmost importance to ensure that the tip o ring

behind the filter holder is fitted and that the tip is tight.
