Pressurising from an external pressure source
A pressure-reducing valve must be fitted between the gas cylinder and the outlet connection of
the hose. The maximum pressure on the outlet side of the reducing valve must not exceed
18.9 bar (275 psi)
To pressurise the pedestal from an external pressure source, proceed as follows:
1. Rotate the steering ring [21], so that the pressure gauge [1] is visible through the
window.
2. Remove the Schrader valve cap [3] and connect the charging line from the pressure
source.
3. Turn on the pressure supply and slowly increase the pedestal pressure until it is
equal to the calculated pressure plotted on the balance graph.
4. Increase the pedestal pressure by a further 1.5 bar (20 psi). Do not exceed the
maximum working pressure indicated by the leading edge of the red sector on the
gauge [1].
5. Disconnect the charging line, and refit the Schrader valve cap [3].
Pressurising the pedestal using a portable pump
A portable pump (part no. 3357-21) is available to pressurise the pedestal manually. To
pressurise the pedestal using a pump, proceed as follows:
1. Rotate the steering ring [21] so that the pressure gauge [1] is visible through the
window.
2. Remove the Schrader valve cap [3].
3. Set up the pump following the manufacturer’s instructions. Connect the hose to the
charging valve on the pedestal.
4. Using full, steady strokes increase the pedestal pressure until it is equal to the
calculated pressure plotted on the balance graph.
5. Increase the pedestal pressure by a further 1.5 bar (20 psi). Do not exceed the
maximum working pressure indicated by the leading edge of the red sector on the
gauge [1].
WARNING! DO NOT exceed 4 bar (60 psi) without a balancing load installed.
WARNING! DO NOT adjust the pressure relief valve. Personal injury and
pedestal damage may occur.
NOTE: The Schrader valve cap forms a primary pressure seal. Always replace
the cap and secure.
