Vacuum Pump Protection – If vacuum pump protection is turned ON, thevacuum pump will automatically be turned off if a “Vacuum Leak” alert ispresented. This will protect oil filled pumps from losing their oil andpotentially damaging the pump in the event of a major vacuum leak. Thefactory default setting for vacuum pump protection is ON, and it is highlyrecommended that it remain in the ON setting. If vacuum pump protectionis turned OFF, the pump will continue to run after a “Vacuum Leak” alert ispresented (i.e. there is no protection for the pump in the event of a majorvacuum leak). |
