Chapter 5 Start-Up and Operation

The machine was filled with hydraulic fluid and cycle tested at the factory. The shipping process may have caused

the fluid to drain out of the pump head and back into the sump. THE PUMP HEAD MUST BE PRIMED WITH

HYDRAULIC FLUID PRIOR TO OPERATION. This is accomplished by removing the hex plug on the pump head labeled

To start the machine after installation, turn the main power switch to the "ON" position. It will begin its automatic

operation by starting the hydraulic pump. The pump will continue to run until it has reached its operating pressure.

The photovoltaic sensor in the ice hopper will send a "start" signal to the ice supply system if no ice is present in the

hopper. When the hopper is full, the photovoltaic will send a "stop" signal to the ice supply. The BP360 will begin to

form the ice block at this time.

When the block is formed, it will drop out of the exit slide assembly, and the next cycle will start.

Observe the machine for a minimum of four (4) cycles of block production to confirm the satisfactory operation of the

machine. Check the limit switch trip points in relation to the position of the pressure and resistance pads. These were

properly set at the factory, but could have been affected during shipping. This will ensure proper machine operation and

maximum material throughput.

To shut-down the BP360, turn the main power switch to the "OFF" position. This switch can also be used for emergency

situations.

The design of the ice supply system that feeds the BP360 should be carefully considered. Typical applications use a

screw conveyor. Some applications may require small ice fragments or snow to be delivered to the machine. Special

considerations should be made for this type of ice:

•

The conveyor to handle small ice must not be overloaded. Material must be conveyed at a level below the

lowest elevation of any hanger, bearing, or other obstruction. The best conveyors have no intermediate

obstructions (i.e. – continuous helical screw with end bearings only).

•

For a screw conveyor application, the clearance between the rotating screw and the trough should be no

greater than 0.005".

The ice supply system must start and stop in response to the signal from the photovoltaic sensor in the BP360 ice

hopper. The timing of the ice cut-off slide in the machine has been set to permit a limited degree of coasting in the

supply system. Too much waste in the supply can result in a backup of ice above the top of the hopper, causing feed

plugs or ice spillage. Screw conveyors, if used, should be inclined at a slight downward angle, ensuring that the conveyor

is self-purging. This is especially true since the conveyed ice is typically moving from an area below freezing, to the block
