INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
1 ABOUT THE MANUAL
This manual has been prepared as an aid and
guide for personnel involved in installation or
maintenance. All instructions must be read and
understood thoroughly before attempting any
installation, operation or maintenance.
Safety instructions
Emerson does not have any control over the
manner in which its frost proof extension is
handled, installed or used. Emerson cannot and
will not guarantee that a frost proof extension is
suitable for or compatible with the user's specific
application.
CAUTION
Safety glasses should be worn when installing a frost
proof extension. Failure to follow any instruction
could possibly result in a malfunction of the frost
proof extension resulting in loss of ability to read
liquid level, property damage or physical injury.
2 INTRODUCTION
2.1 Features and specifications
Penberthy frost proof extensions are designed
to be mounted readily and able to fit all vision
slot lengths of Series L, M, H and LC liquid level
gages. Penberthy frost proof extensions will
extend the viewing window glass out beyond the
range of frost build up.
2.2 Design ratings
Penberthy frost proof extensions are available
in three different extension sizes to handle the
temperature ranges as listed below:
3 INSPECTION AND PERFORMANCE
CONFIRMATION
3.1 Receiving inspection
Safety instructions
Exercise care in handling extension parts
to avoid scratching, denting or otherwise
damaging the polished edge of the extension.
Any marks on the polished edge, as well as dirt,
paint, or tape, will result in a reduction of ability
to read liquid level.
Upon receipt of frost proof extension, check
all components carefully for damage incurred
in shipping. If damage is evident or suspected,
do not attempt installation. Notify the carrier
immediately and request a damage inspection.
3.2 User’s rating inspection
The user should confirm that:
1. The frost proof extension size and length
conform to the description on the user's
purchase order.
2. The operating conditions described in
the purchase order agree with the actual
operating conditions at the installation site.
3. The actual operating conditions at the
installation site are within the application
data shown on the applicable technical data
sheet or product proposal referred to above.
4. The materials of construction of the frost
proof extension are compatible with the
surrounding atmosphere in the specific
application.
