Icepack Operating Instructions

Normal operation is controlled fully from the sleeper control panel

Starting the Icepack -

  •  
    		•  Turn the fan control to the off position (fully anti-clock wise).
  •  
    		•  Turn key and hold in start position until engine starts (fully clock wise).
  •  
    		•  Allow engine to run for 15 seconds.
  •  
    		•  Set the fan and temperature control knobs.

    Stopping the Icepack -

  •  
    		•  Turn the key to the off position (fully anti-clock wise).
  •  
    		•  Press and hold stop button until the engine stops.

    Icepack Servicing Schedule -

    Every 10 hours
  •  
    		•  Check engine oil level

    Icepack Servicing Information  

    Engine Oil -

  •  
    		•  Engine oil level can be checked with the dipstick located on the RHS of the Icepack.
  •  
    		•  Check the engine oil level with the engine stopped.
  •  
    		•  Correct oil level is indicated by complete coverage of the dipstick.
  •  
    		•  The lower end of the dipstick indicates minimum oil level (not recommended).
  •  
    		•  Oil must be API service CC-class or better.
  •  
    		•  Sump capacity is 1.3 litres.

    Engine Run Speed -

  •  
    		•  The engine operating speed can be adjusted with the throttle lever located on the LHS of the Icepack.
  •  
    		•  Start the engine and set the fan speed and temperature to maximum (fully clock wise).
  •  
    		•  Adjust the engine speed for minimum vibration, noise and engine strain (usually near half throttle).
  •  
    		•  Check the truck voltage gauge to ensure that the Icepack alternator is charging correctly.
  •  
    		•  Turn the fan speed to off (fully anti-clock wise) and recheck for vibration.

    Air Conditioning System -

    The evaporator is connected to the Icepack unit with a No.10 hose, which goes to the compressor inlet with a 90 degree fitting, and a No.6 hose, which connects to the outlet of the receiver dryer also with a 90 degree fitting. Inline service ports are connected in these lines at a convenient location.

    50 ml of Sanden SP10 pag oil should be introduced to the system. The system should be gassed using R134a to a high side pressure which correlates to the temperature given by the temperature of the day plus 20 deg.C plus 10% (or (T+20)x1.1 ). If the site glass of the receiver dryer clears before this pressure is reached then the system is full of gas at this point.

    Fuel System -

    Hoses connected to the Icepack are the fuel pick up and return lines. The fuel pick up line is the hose that is attached to the fuel filter inside the Icepack. This hose is attached to the fuel spear in the top of the tank. The return line is attached elsewhere to the same tank.

    The fuel system flow diagram is:

    Electrical System -

    The Icepack is connected to the control panel inside the sleeper with a 7 core cable with a white 8 pin plug on each end. The control panel is connected to the evaporator with similar cable with a black 8 pin plug on each end.

    Power from the battery is supplied with the heavy orange lead that is attached to the back of the starter motor and an earth lead is connected from a bolt on the motor to the truck chassis.

    There are two power relays located on the condenser in the unit that control the ignition (inner relay) and compressor (outer relay) circuits. Relays are 5 pin 40 Amp normally open contact type.

    There is a circuit breaker located below the relays.

    The alternator is 85 Amp with external custom regulator.

    The regulator changes the charge voltage when the compressor is engaged and must only be replaced with the correct unit from Haultech Engineering. It has an internal fuse and voltage adjustment. Adjustment is not normally required in service.

    Correct charge voltages are:

    Compressor engaged: 13.1 V
    Compressor not engaged: 14.5 V

    The fuel lift pump is electric and located under the compressor in the unit. Power is supplied with a brown wire when the ignition is on.

    The wiring loom in the unit is colour coded as follows:

    Red 12 V permanent live power
    Black Earth 0 V
    White Ignition switch signal and also Df terminal connector between the
    alternator and voltage regulator.
    Brown Switched power, 12 V when key is on.
    Blue Compressor wiring.
    Green Stop solenoid wire, 12 V when stop button pressed.
    Yellow Start signal wire, 12 V when key held in fully clockwise position.
