Safety
You must adhere to the following safety precautions at all times when
working on the Compac equipment. Failure to observe these safety
precautions could result in damage to the loading post, injury, or death.
Make sure that you read and understand all safety precautions before
installing, servicing or operating the Compac equipment.
Ensure the system design does not allow the inlet pressure
to exceed its rating. The unit does not include any safety features to protect
against excessive inlet pressure. If necessary, suitable protective devices
should be fitted before the inlet.
Observe the following electrical precautions:
Never tighten a fitting under pressure, even if a fitting or joint
is leaking. Always depressurise the line first
Never disassemble a fitting under pressure. Always
depressurise the line first
Be very careful when disassembling frozen pipework, as gas
pressure may be trapped and suddenly released. Always depressurise the
lines first.
Never reuse any O-ring seals that have been in a high
pressure gas atmosphere and then exposed to air. These o-rings swell and
cannot be reused. Always make sure you have a new seal kit available to
replace the seals before disassembly
Make sure that all internal surfaces are cleaned and that
sliding surfaces are lightly greased with O-ring lubricant before reassembly.
Dust and dirt entering components reduce the life span of the components
and can affect operation
Make sure the service area is thoroughly cleaned before
starting to service CNG components. Dust and dirt entering components
reduce the life span of the components and can affect operation
Observe the following electrical precautions:
Always turn off the power to the CNG unit before removing
the box lid. Never touch wiring or components inside the CNG Loading
post with the power on.
Never power up the CNG unit with the flameproof box lid
removed.
Always turn off the power to the unit before removing or
replacing software or memory IC's
Always take basic anti-static precautions when working on
the electronics, i.e., wearing a wristband with an earth strap.
