Installing a gas cylinder
Apply the brakes to the wheels before installing the gas cylinders. The gas cylinder needs to be placed
carefully onto the trolley as the cylinders can weigh more than 15kg.
Place the cylinder behind the lip on the base place to ensure that it is correctly positioned.
It is essential to restrain the cylinder using the polyester webbing straps provided to prevent it from
accidentally falling.
The black buckles should ‘click’ closed and be adjusted to ensure that the cylinders are held securely.
Before connecting the cylinder to the system, make sure that the regulator tap has been switched off
to prevent gas from escaping. This depends on the type of cylinder in use:
● If using BS14, provided by BOC, twist the adapter nut onto the cylinder thread and tighten it using
the spanner provided. Ensure that the PTFE washer is in place in the gas cylinder connector (see
‘B’, page 3).
● If using INOMax, provided by INO Therapeutics, screw the connector on and tighten by hand only.
● If using Kinox, provided by Air Liquide, screw the connector fitted with an O-ring (rotating black
plastic connector) onto the bottle top and tighten by hand only. If the fitting does not have an O-ring,
a spanner must be used to tighten it.
● If another manufacturer’s gas is used, seek advice from the supplier or contact Bedfont.

Installing a Gas Cylinder
Before installing the gas cylinder, ensure the
NOxBOXmobile trolley is placed on a firm level
surface, positioned such that easy access to
the cylinder mounting platform is available, and
engage the trolley brakes before manoeuvring
cylinders on or off the trolley.
For safe cylinder handling refer to “Manual
Handling” notes (page 7).
Place the cylinder onto the trolley platform,
seating it against the upright supports provided.
Cylinder must sit inside the raised rim of the
trolley base. Restrain the cylinder with the
provided nylon webbing straps correctly fitted to
prevent the cylinder from toppling in use. Place
the strap around the cylinder and pull the free-
end until the strap lies tight around the cylinder,
the metal buckle will automatically grip onto the
strap and hold in place.
WARNING: gas cylinders can be very
dangerous if they topple over. All safety
measures must be in place to ensure the
cylinders are properly secured when on the
trolley platform.
Prior to connecting the cylinder:
● Ensure the gas control valve is shut (this
should be the default position for the valve).
Any leaking unregulated gas should be very
obvious.
● Remove any safety caps from the threaded
valve connection on the cylinder.
Cylinder connections vary depending on
territory. Refer to your local distributor for details
on your connection type.

washer
● Visually inspect the connector on the hose
for any wear or damage
● If there should be a sealing element, ensure
it is present and free from apparent wear or
damage. If it is damaged it must be replaced
prior to use. (see Figure 2, illustrating a
BS14 style connector with PTFE washer
seal)
● Introduce the connector to the cylinder valve
and carefully hand-tighten the nut. Do not
force the nut if it sticks, reverse the nut and
ensure the nut is not cross-threading and
that the thread is free from damage before
attempting to reconnect.
● Once hand-tight, use the supplied
adjustable spanner to tighten the connection
to the cylinder until it feels firmly tight.
Over-tightening the connection can cause
damage.
● Refer to the gas manufacturer’s instructions
for specialist connections. Do not use any
inappropriate tools on hand-tighten only
type connections.
Repeat the above steps to attach the second
cylinder.
