Power Dissipation
Table 1-3 lists the power dissipation and BTU ratings for the BBU-Video and BBU-Video Dual
Screen. Current values for all machines are based on a 120VAC configuration, with Bill Acceptors
installed.
The British Thermal Units (BTUs) were calculated by using the following equation:
BTUs = 3.413 * voltage * current
Any decrease in BTUs due to actual work performed (spinning Hopper motor) was neglected. The
BTU calculation for game play should be used when determining air conditioning requirements, as
Hopper payout occurs infrequently when compared to standby and play conditions.
Features: Doors
The BBU features easy serviceability and quick access to parts:
The BBU Main Door and Lower Door provide access to many of the internal components,
