Unpacking
Unpack the instrument carefully. Inspect all units for dam-
age. Report any concealed damage to the carrier within 24
hours. Check the contents of the packing slip and report
any discrepancies to Magnetrol. Check the nameplate model
number to be sure it agrees with the packing slip and pur-
chase order. Check and record the serial number for future
reference when ordering parts.
Before You Begin
1. Ensure that the length and inside diameter of the mounting
nozzle are sized correctly to allow for switch actuation at
design levels. Refer to Figure 1.
2. Ensure that the mounting nozzle or coupling is within 3°
of horizontal. If mounting the Tuffy in an external cage,
ensure that the cage is mounted within 3° of horizontal
and that the top/bottom piping is within 3° of vertical in all
directions.
3. Ensure that the area is free of metallic particles which might
be attracted to the magnet holder/counterbalance and inter-
fere with the function of the Tuffy.
No special equipment or tools are required to install the
Tuffy Liquid Level Switch. The following items are recom-
mended:
• Wrenches, flange gaskets and flange bolting appropriate for
process connection(s).
