Foreword
The unit is manufactured, checked and supplied in
accordance with our published specification, and when
installed and used in normal or prescribed applications,
with the lid in place and within the parameters set for
mechanical and electrical performance, will not cause
danger or hazard to life or limb.
Warning: Units must be selected and installed by
suitably
accordance with appropriate codes of practice so
that the possibility of failure resulting in injury or
damage caused by misuse or misapplication is
avoided.
Warning: Before installation check that the
instrument characteristics comply with process
and plant requirements
Warning: The user should ensure the equipment is
suitable for use in the application with aggressive
substances.
Warning: The users attention is drawn to the fact
that, when the unit is 'live' with respect to electrical
or pressure supplies, a hazard may exist if the unit
is opened or dismantled.
Warning: Where any special condition of the
product has been required as identified by the last
4 digits of the part number, follow the necessary
safety instruction for a correct installation.
Allowed over range
Pressure exceeding the adjustable range can be allowed
up to the max pressure stated on the nameplate.
Transitory electrical over ranges can have a destructive
effect on the microswitch.
Ambient temperature
The surface temperature of the instrument is influenced by
the process temperature, electrical working conditions,
installation and environmental. Special attention must be
taken to avoid exceeding the limits specified on table
below (i.e. remote mounting, valves, siphons, diaphragm
seals. See Mounting).
