At start up the timer board will not allow the dispenser to power up until three minutes, the gas detector must not sense Hydrogen. This
is required for a complete air change in the dispenser enclosure to eliminate any explosive gasses.
The timer board relies on a charged battery for proper operation. If the battery is discharged, the timer will have to be bypassed through
the bypass push button on the timer board as shown in
Figure 1.16 . The switch will have to be held until the battery reaches a suitable
charge level. This could take several minutes. The dispenser enclosure must be closed and have a purge pressure of at least .15 inches of
water for proper battery charging.
