Housekeeping

To ensure that the Fox Model BPT600 unit performs the function for which it is installed there are some very
basic housekeeping functions that need to be performed. The interval between these activities is very much
site specific. A responsible approach to these functions will provide the maximum benefit to the environment.

    •   When large items of floating debris (such as plastic bags, drink cans etc.) are observed on the inlet
        grate of the unit they should be collected and disposed of in a suitable manner. The Fox BPT600 does
        not capture these items they simply prevent them from entering the stormwater discharge through the
        unit. If they are not removed they could still be harmful to the environment if they are washed or
        blown off the site.

    •   Regularly inspect the unit for a build up of captured pollutants within the silt basket. This should be
        done on a weekly basis or more often if large quantities of silts are being retrieved.

    •   To empty the silt basket the slide bolt on the grate should be slid back using a screwdriver or similar
        and the grate lifted and moved forward to enable access to be gained to the basket.

        Please note that the grate is heavy and proper care should be taken when removing it.

            •   Remove the silt basket and dispose of captured pollutants in a suitable manner such as
                emptying it in a garbage bin or similar.

            •   As soon as the basket has been emptied it must be replaced and the grate returned to its'
                locked position.

        For safety reasons the unit should never be left unattended when the grate and basket are
        removed. For maximum environmental protection and to reduce maintenance costs the silt
        basket should always be in place within the unit.


Regular servicing of the Chamber.

From time to time the chamber of the unit will need to be cleaned of silt build up and retained hydrocarbons.
The frequency of this activity will depend on the site conditions of each installation.

    •   Fox Environmental Systems recommend that initially the units are cleaned on a 3 monthly basis. This
        service should consist of a minimum of the following activities.

            •   Carefully capture any floating hydrocarbons in the chamber.

        Captured hydrocarbons must be disposed of in a manner prescribed in the Environmental
        Protection Act.

            •   Pump water from within the chamber and filter through a minimum 20 micron filter before
                allowing discharging into the stormwater system.

            n   Remove all silt and sediment build up from within the chamber and dispose of it in a suitable
                manner such as emptying it in a garbage bin or similar.

            n   Following each service quantities of pollutants that are removed should be recorded to enable
                proper assessment of the serving frequencies required to be ascertained.
