5.3 Riser, Manhole and Junction Box Installation
Install the components shown below after the probe installation location in the tank has been selected.
WARNING: To prevent explosion or fire, it is recommended to use non-
sparking tools in an environment that could contain flammable hydrocarbon
vapors. DO NOT USE CORDED ELECTRIC OR BATTERY OPERATED
POWER TOOLS. Only use pneumatic or manual tools.
5.3.1 Riser Assembly
A four (4) inch diameter riser pipe must be installed on the tank opening where the probe will be installed.
The riser pipe must be of sufficient length to hold the probe head, connector and an applicable length of
cable.
An adapter collar and riser cap must be installed on the riser pipe to keep contamination out of the fuel tank.
The riser must be tapped to accept the correct thread for the adapter collar and riser cap assembly.
NOTICE: Tap the applicable threads on the top of the riser before it is installed so that
contamination does not enter the tank.
NOTE:
The probe cap and adapter kit below can only be used for the OPW-FMS 924B probe.
For DMP probes, use an applicable riser cap with a 9.50 mm cable gland.
OPW-FMS recommends to use the OPW 62M Monitor Probe Cap & Adapter Kit (P/N 30-0219). The
illustration below shows the cap and adapter dimensions and thread specifications for reference.
