Thank you for purchasing a MiniCAFS unit. MiniCAFS is designed to give safe and reliable service – however, BEFORE operation it is essential that the Operating Instructions are carefully read and understood. A risk-assessment of this equipment has been conducted with the following results: MAINTENANCE It is the responsibility of the user to ensure that the equipment is maintained in a safe operational condition, as per regulation 5 in the Provision and Use of Work Equipment Regulations 1998.
MANUAL HANDLING If the unit is to be removed from the appliance the design incorporates suitable lifting points. The secondary starting method (hand-start) provided MUST BE USED WITH CARE. Follow the operating instructions provided. ENVIRONMENTAL PROTECTION It is illegal to pour engine oil and other contaminants onto the ground, down sewers or drains, or into water courses.

INSTRUMENTS 1. WET or DRY foam selector 2. FoamLogix display and control 3. CAFS or Foam selector 4. Hours run counter 5. Air dump valve 6. Air pressure gauge 7. Wet or Dry foam indicator ENGINE CONTROLS 8. High compressor oil temperature 9.
8.5 litre fuel tank, which is sufficient for in excess of one hours running. The oil in the rotary air compressor is cooled by water taken from the vehicle main pump via the water supply line. To ensure adequate cooling water must be supplied to the unit prior to starting the engine.
FoamLogix The FoamLogix 2.1 foam proportioning system consists of three main components: 1) Foam Pump / Motor Assembly, mounted on top of the unit. 2) Control Panel, mounted on the side of the unit. 3) Flow measurement and injection manifold, mounted on top of the unit. All three parts work together to provide accurate and reliable foam proportioning.
1. If the unit is installed in the side locker of a fire fighting vehicle, provision must be made for access to the engine oil dipstick (A), compressor oil-fill (B) and sight glass (D), all located on the rear side of the MiniCAFS. The drive motor is air-cooled, and cooling air must be allowed to flow unhindered into and out of the unit.
5. Connect a water supply of 4-10 bar pressure from the main pump to the inlet connection on the MiniCAFS manifold. This should be of φ50, flexible, non-kinking hose. An isolating valve must be provided between the vehicle pump and the MiniCAFS unit to prevent the unit being pressurised when not being used.
COMMISSIONING/ START-UP PROCEDURE Caution: The heat exchanger return flow is over 40 l/min. This flow must not be restricted. Caution: The unit should be run in open air with any compartment doors open and the containment drawer ideally pulled out to improve ambient airflow. 1.
FoamLogix control panel functions - Check that all the necessary connections have been made as described in the previous sections Run the compressor for 30 seconds to allow oil to circulate. Press the CAFS switch (3, P8) on the instrument section. Stop the unit and check compressor oil level –...
”no Pr” = No prime display When prime is achieved, deselect simulated flow by pressing both up ↑ & down ↓ at the same time. Return the bypass valve to the inject position (arrow points to right). The unit is now ready to run. OPERATING MiniCAFS FROM A VEHICLE WATER SOURCE 1.
FoamLogix Control Panel 1. Discharging foam agent only 1.1. Set water feed from supply pump at required pressure 1.2. Ensure that the foam only option is selected by pressing the bottom of the Foam/CAFS selector switch, marked with the symbol - 1.3.
Wet Foam or Dry Foam 2.4. A continuously variable foam type from WET to DRY is available, selectable by the pump operator. 2.5. The WET or DRY foam composition is selected by using the WET/DRY control on the panel (No.1 Page 7). An indication of foam type is given by the WET or DRY foam indicator (No.7 Page 7), but the pump operator may choose to optimise the liquid flow as displayed in the FoamLogix display.
TO OPERATE FROM A REMOTE FOAM SUPPLY Foam agent can be inducted out of conventional commercial canisters. The base of the canisters must be above the FoamLogix Pump and the MiniCAFS. A suitable dip tube should be manufactured for the suction line. The bypass pipe should be fed back into the foam canister.
MAINTENANCE Weekly: Check the oil levels and top up if necessary. Check the belt tension/condition and adjust if necessary. Check the hose connections. Check battery charge. Every 50 hours or every 3 months Check and clean the water supply filter (M, Page 12) for debris Every 100 hours or every 6 months (whichever comes first): Change the engine oil and filter.
