Pressure regulators
There are three pressure regulators inside the
Pneumatic section:
1. REG 1 (20 kPa) controlling the pressure in the
Mushroom valve control gas supply.
2. REG 2 (320 kPa) controlling the O
the Instant O
Supply-block.

3. REG 3 (100 kPa) controlling the pressure inside
the Fresh gas pressure container.
The pressure regulators are keyed to avoid mixing.
Safety valves
There are five safety valves inside the Pneumatic
section:
1. SV 1 (600 kPa) protecting the vaporizers.
2. SV 2 (14 kPa) located in the drive gas channel.
3. SV 3 (18 kPa) located at the Fresh gas pressure
container and the Inspiratory fresh gas valve.
4. SV 4 (14 kPa) located in the fresh gas channel.
5. SV 8 (-3.5 kPa) protecting the pressure
transducers from negative pressures.
To remove SV 1:
• Remove the fresh gas pressure container.
• Using a 3 mm insex bit, remove the screws holding
the cover and lift off the cover.
To remove SV 2–4:
• Use the KION service tool "Wrench for safety valve"
to unscrew the valve.
To remove SV 8:
• Pull off the complete valve housing from the nipple
on the Inspiratory gas block
Note: SV 8 must be mounted vertically as shown in
the illustration. A deviation of ±10° is permissible.
