Installation Guidelines

Ensure the probe lead is longer than the sleeve length during installation.
For probe penetration lengths (Option C + Option D) greater than 300 mm (12 in), install additional sleeve support near the probe to prevent resonance.
When using the cable seal grip (Option E:03), ensure grommets are correctly sized for the cable diameter to maintain environmental seal integrity.
Avoid exposing 3300 XL probes to temperatures below -34 degC (-30 degF) to prevent pressure seal damage.
