System Alarm Conditions NFPA 99 

The following is a description of how alarm conditions will affect the operation of the system. 
 

 

If a “Lag pump in operation” alarm is installed in the panel, observe the following. Such an alarm is usually only 
supplied with medical packages. The alarm consist of a flashing light (usually a bubble light located on the top of the 
panel) and an audible alarm. The alarm will trigger when the “lag” pump starts up.  The alarm will not affect the 
operation of the system. The light will flash and the audible alarm will sound. The audible alarm can only be silenced 
by physically pushing the “alarm silence” button. This will not stop the lag pump on light from flashing. The flashing 
light can be reset by physically pressing the “alarm reset” button.  

 

 

Note: 

If the lag pump is still operating when the “silence” or “reset” buttons are pressed, the alarm will continue to 

“sound”. The alarm will only reset if the lag pump is not running.  

 

 

“Transformer failure” light (optional). Only installed if more than one control voltage transformer is supplied. If the 
transformer failure light is illuminate, one of the transformers has malfunctioned and the second one has picked up. As 
long as a back-up transformer is available, the above alarm will not affect the operation of the system. If both 
transformers fail, the system will shut down.  

 

 

“High temp” light. If the high temperature light illuminates, the affected pump will shut down unless otherwise 
specified at time of purchase of this equipment. The backup pump(s) will continue to operate unless a high temperature 
(or other) alarm occurs in those pump(s). 

 

 

“Low level” light (optional). If the low oil level light is illuminated, the affected pump will shut down. The backup 
pump(s) will continue to operate unless a similar condition occurs in those pump(s).  

 

Maintenance 

WARNING:

 Before attempting any maintenance such as changing the fluid, remove all power from the system by 

switching off the main breaker or disconnect switch. This will prevent the system from automatically starting from a 
vacuum switch.  

 

Pump oil level (Check daily):

 

Under normal circumstances it should not be necessary to add oil between recommended oil changes. A significant drop 
in oil level means there is either an oil leak, a broken exhaust filter or a leaking anti-suck back or inlet check valve.  
 
It is normal for the oil to be foamy and lightly colored. If the oil is milky or dark colored, it is burned or contaminated and 
must be changed. 
 
Check the oil level only when the pump is shut off. The best time to check is before start-up. Replenish oil if the level 
drops below the ¼ mark of the top sight glass. Oil must be added through the fill port only. 
 

CAUTION:

 Do no add oil while the pump is running, since hot oil can escape from the fill opening.  

 

Oil change 

Change oil every 500 hours of operation or when oil darkens. Drain oil when hot, use caution and properly dispose of 
the oil.  
 

CAUTION:

 A more frequent oil change might be required if the oil becomes milky or dark colored. A dark colored. A 

dark  color  is  a  sign  of  varnishing  which  would  reduce  the  life  of  the  pump,  vanes  and  exhaust  filters.  Our  specially 
formulated Travaini oils are generally far more resistant to varnishing than normal motor oils.
