Recommended Installation Locations

AGF recommends installing the CORRi n SITE in areas of sprinkler systems which
have historically demonstrated corrosion issues. Locations where the water is
most oxygenated such as: upstream of fire pumps, immediately downstream of
alarm valves, and near floor control valves where cavitation is prevalent should be
considered. Other areas of consideration include the lowest and highest building
levels, at the end of branch lines where pockets of air may become trapped, and
sections previously impacted by corrosion related failure.

CORRi n SITE is recommended for both wet and dry systems, and can be
installed vertically or horizontally depending on its location in the system.

CORRi n SITE Plug Orientation for Vertical Installations

Any orientation on a vertical run of pipe in either a wet or dry system is considered
acceptable. Refer to installation instructions and Fig. 2 below for both the M7700
Inline Pipe and M7800 Mechanical Tee.

CORRi n SITE Plug Orientation for Horizontal Installations

Wet System

AGF recommends positioning the plug at the top of the clock between 1 and 3 or
9 and 11, but not directly vertical at 12 (see Fig. 1).

Dry System

AGF recommends positioning the plug at the bottom of the clock between 3 and
5 or 7 and 9, but not directly vertical at 6 (see Fig. 1).

M7700 Inline Pipe Installation

The CORRi nSITE M7700 inline pipe has a 10” takeout with grooved pipe ends.

After choosing an installation location plumb the 10” pipe into the system 1.
using the appropriately sized groove couplings. Before tightening couplings,
orient the monitor’s plug to desired position (see Fig. 1).

After tightening couplings to manufacturer’s specifications apply appropriate 2.
sealant to the plug’s threads and install into the pipe’s port (see Fig. 2). Orient
the monitor’s plug so that the text is easy to read.

Complete installation tag and attach it to the eyelet in the monitor’s plug. 3.
Record inspection dates on the monitor’s label as necessary.
