Laversab 6300 User Manual page 14

[11] Pitot Vent :
In the event that the 6300 is in-operable due to a malfunction or due to loss of power, it is
possible to vent the Pitot system manually. This is done using the metering valve labeled
"Pitot Vent". This valve is a positive shut-off valve. Opening this valve slowly will vent the
Pitot output of the 6300 to ambient pressure. While venting, care must be taken to maintain
the airspeed within limits of the indicator on the aircraft.
Caution: The Pitot Vent is NOT connected to the Static Vent. There is NO cross-bleed.
When venting is completed, close the valve.
Caution: Do not over-tighten the valve as this may damage the seat of the valve.
