  • Page 9: Introduction

    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.
  • Page 10 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.

  • Page 11: Installation

    INSTALLATION Caution: MiniCAFS is shipped without oil in the Compressor or Engine. Oil MUST be added before the unit is started. All connections are labelled and must be secured before starting the unit. ©Hale Products Europe. Our policy is one of continuous development.

  • Page 12 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.
  • Page 13 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.

  • Page 14: Commissioning/Start-Up Procedure

    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.

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.

  • Page 19: To Operate From A Remote Foam Supply

    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.
  • Page 20 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.
