Maintenance intervals
Visual inspection
At least every 3 months to determine operational readiness.
Inspect the complete VarioGard system for damage and check that gas
access to the transmitters is unobstructed.
Routine inspections
As required by local regulations (in Germany, VDI 2053 - Ventilation and air
conditioning systems for car parks and tunnels / car parks, State car parks
ordinance, etc.).
We recommend having the system inspected by DrägerService at least once
a year.
When necessary
– Change transmitter upper part, see page 64.
Replacement calibrated transmitter upper parts are available from
DrägerService.
– Replace battery (Emergency flashing light power supply) in central unit,
see page 65.
We recommend that a service agreement be concluded with DrägerService
for maintenance and repair.
