Setup Hints for "tropic" and "exotic"-Systems

Setting up the system is quite easy and follows these steps :

1 - Connecting to a Water Vessel

  1. Select the desired vessel - for instance a clean plastic container - and drill some cm above the bottom a hole with 12 mm ; take care to select a flat piece of wall and make sure no burr is left.
  2. Insert the bulkhead connector from the outside into the vessel and make sure that the fixed flange with the rubber gasket is on the outside. Fit the nut on the thread and fasten it with medium force (carefully plastic is not as durable as metal!)
  3. Cut a short piece of the thick hose[ 8 mm ] with a sharp knife and connect the outside of the bulkhead connector with the clear plastic filter.
  4. The connection of the fine filter with the pump inlet is done with the thick hose[ 8 mm ] ; use the hose as delivered of cut it to length with a sharp knife. Put the hose onto the outlet of the bulkhead connector and the pump inlet [ white plastic nipple].
  5. The connection from the pump outlet to the fogging nozzles is done with the 6mm hose:
  6. Please take care that the total length of hose on the pressure side (pump outlet) should not exceed 6 m.
    The slight elasticity of the hose will shorten the fogging time as too long hose segments will take some time until they are pressurized.

2 - Positioning the Pump

The position of the pump is not critical and can be selected according to your wishes; the position depends on the total length of feeder hoses, the position of the hoses and the electric outlet for the switching clock.

However make sure that the pump is not required to suck up water - the water vessel should be positioned at the same height or higher than the pump.

    Please make also sure that the pumps ("tropic" and all "exotics" as well as all others) should NEVER be allowed to RUN DRY - therefore take care to refill the water vessel in time !

3 - Mounting Nozzles and feeder hoses

The nozzle is connected with a nozzle mount and a gasket to the feeder hose.

If you are utilizing more than one nozzle please make sure to use the various connector- and distributor-components which are available.

Refer to the page with Configurations.

Mount the nozzles in these steps:

  1. Fit the gasket onto the nozzle thread up until the neck
  • Screw the nozzle manually into the mount until it stops
    In case the nozzle cannot be screwed in manually - too tight thread tolerances may be the cause, use spanners with 12 and 14 mm to tighten it -
    there is NO NEED to tighten it with force !
    1. Insert the clean cut end of the feeder hose into the nozzle mount until it stops
    2. Insert the other end of the feeder hose into the pump outlet (6 mm ) until it stops.
  • 4 - Starting the System

    Whenever you have set up all components you can start up the system ...

    1. Fill water into the vessel
    2. For a start set the fogging time to maximum
    3. Insert the pump into the switching clock and connect it to an electric outlet with 230 V
      Set the current time by rotating the timer wheel - the current time should be positioned at the black arrow
    4. Set the switching clock to general ON at the ON - Symbol "I" on the side of the clock.

      The pump control will always start with an interval

      Afterwards the preset time will be used for fogging
  • When starting up the system will need to fill all hoses and components with pressurized water - therefore it can be that it needs some fogging cycles until the real fogging will begin

  • Now set the desired times for switching ON and OFF with for the system by switching to clock-operation and setting the cams on the timer wheel

  • After setting the desired time for fogging on the knob of the control box the system is ready for operation

  • Hint : Take care to use very clean water - even minuscule particles in the water can clog the nozzle after a time. Very often collected rainwater contains quite some particles - it is advised to filter the water, this can be easily done with a plain paper coffee-filter

    5 - Setting the Operating Parameters

    We do not attempt to give you general advices for the settings; you know best how much water (humidity) your application needs and therefore how to set the timer of the pump control.

    Important: the pump can be operated continuously if needed with maximal fogging time for many hours !


    Even if you take care only to use clean water it is possible that invisibly small particles can slowly clog up the fogging nozzles which results in reduces fogging performance.
    If you filter the water, e.g. with a normal paper filter for coffee machines, these particles will be removed to a high degree. Whenever the fogging performance begins to degrade follow the instructions to clean the nozzles.

    Cleaning clogged Fogging Nozzles

    In case the fogging performance begins to falter the nozzles should be cleaned. Proceed with the following steps :

    • Unscrew the nozzle(s) from the nozzle mount
    • Remove the gasket and extract the nozzle filter by means of a drill or a screw as shown here
    • Put the spare filter(s) for some time in water; if they are fully soaked they can be inserted easier into the nozzle
    • Put the clogged nozzle(s) in an enamelled pot and add some 5 cm of the nozzle cleaning granulate (never use an aluminium-pot !)

    • Let the nozzle(s) soak for some time in the cleaning solution
    • Rinse the nozzle(s) afterwards several times with clean water
    • Insert a new (watered) nozzle filter and push it down manually

    • Now push the filter tightly into the nozzle by using a punch or a similar tool which must be smaller than the inner diameter of the nozzle. A wooden board as support is helpful
    • Put the gasket back onto the nozzle thread
    • Screw the nozzle into the mount and tighten it manually

    Cleaning the Fine Filter

    The transparent pre-filter CANNOT be disassembled !

    Dismount the filter and flush it in reverse direction - this will remove all particles

    Inserting and Extracting Hoses

    Mounting and dismounting hoses from the various components is quite easy.
    Please note that all gasket mechanism of the system are self sealing under pressure - therefore a small trick is needed to dismount a hose.

    To insert a hose just push it into the opening until it stops. It will seal automatically whenever pressure is applied to the system.

    To remove a hose push the black rim of the gasket away from the hose while pulling on the hose.
    It should come free quite easily.
