If the mouthpiece is used, make sure that there is no

12.3 PERIODIC CHECKING AND INSPECTION
The checks described in this section must be regularly carried out between dives (after one diving occasion
and before the next one).
12.3.1 CHECK THE RESERVE VALVE HANDLE
1. Install the Divator diving apparatus in accordance with the mounting instructions.
Pressurize the unit.
2
. Check the following:
– The handle functions unimpaired and remains in position (C, D or R).
(
The air pressure must be reduced to check position R.)
– There are no deposits in or around the reserve air handle.
– No parts show signs of wear or damage.
3. Perform a function test; see Section 5.1 “Leakage and function test”.
If the equipment is defective or damaged, it must be repaired by an Interspiro-approved service technician.
12.3.2 CHECK THE MOVEMENT OF THE PRESSURE GAUGE
INDICATOR.
The rst-stage regulator has a throttle opening in the high-pressure connection that limits airow to the
pressure gauge hose and the pressure gauge. This limitation protects the user and equipment if the high-
pressure hose or pressure gauge malfunctions.
1
. Install the diving apparatus in accordance with the mounting instructions.
2. Open the cylinder valve and study the pressure gauge result at the same time. Check that the movements
of the indicator are even and normal. If the indicator moves unevenly or not at all, the pressure gauge is
defective.
3
. Close the cylinder valve, press the vent button on the breathing valve to vent the Divator diving apparatus
and move the reserve valve handle to position R.
If the equipment is defective or damaged, it must be repaired by an Interspiro-approved service technician.
