GENERAL DESCRIPTION
This instruction is for the installation, operation, and testing of GTP-9330 series water detection
probes. This is a single level water detection probe.

It is the customer’s responsibility to select an appropriate weathertight and/or explosion-proof
control box containing an intrinsically safe barrier relay (IS relay). We recommend our GTP-
1750 systems described in Bulletin No.67.
1.
Install the new probe in a ¾” NPT
threaded fitting using Teflon thread
sealant on the threads. A 1 ½” NPT
model is also available. It may be
oriented horizontal or vertical, as
long as any water present in the drain
pipe and fittings will be removed
when the manual drain valve is
operated.
