MAINTENANCE
Reading the Indicators
If your machine is controlled by a digital control module (with touch pad), this design aids in
troubleshooting. The digital panel has indicator lights mounted on the front below the ON/
OFF switch. The indicator lights correspond to the operating devices and should turn on and
off in the following sequence when the machine lid is closed:
1. Vacuum Pump [C-1]
2. Gas Flush Valve [SOL-3] (Optional)
3. Seal Bladder Valve [SOL-2]
(Stays on until completion of cycle)
4. Seal Impulse Contactor [C-2]
5. Ventilation Valve [SOL-1]
The device should be operating when the light is illuminated. If the lights illuminate in the
proper sequence, but there is still a problem, look for the problem in the operating device
itself. If the lights do not sequence properly, look for a problem in the control module.
