Section 3. Plumbing
The cell must be plumbed in a position that is
accessible for maintenance and within 2 meters of
the controller. The cell should be the last piece of
equipment in the circulation system. The cell must
be installed horizontally, level and with correct flow
orientation, see Figure 3 and Figure 4.
1. If you intend to plumb the cell on a bypass,
the bypass must be equipped with isolation
valves, see Figure 3 and Figure 4.
2. Plumb the cell inlet and outlet on vertical
lengths of 50 mm or 63 mm PVC pipe. The
cell inlet and outlet ports are 11.5 cm apart,
see Figure 2. The inlet of the cell is on the side
closest to the electrical lead, see Figure 5.
3. Put the unions onto the inlet and outlet pipes,
4. For 63 mm plumbing, glue the adapters
directly onto the pipes.
5. For 50 mm plumbing, glue the reducers into the
adapters then glue the adapters onto the pipes.
6. Ensure the o-rings are seated properly on the
adapters.
7. Secure the cell to the plumbing by
tightening the unions hand tight. DO NOT
OVERTIGHTEN.
8. Double check cell orientation. The cell inlet is
closest to the cell electrical lead.

CAUTION:
Never store acid directly underneath any
equipment as fumes will cause corrosion and resulting
damage can void your warranty. It is recommended to store
your acid container in a safe, protected well ventilated area.
NOTE: The sensor POD must be positioned after
filtration and heating systems and before the cell.

WARNING
• The cell must be installed horizontally and level.
Improper installation can lead to gas build up which
could result in equipment damage or serious injury.
• The cell must be the last piece of equipment on
the return line, see Figure 3 and Figure 4.
• It is recommended in all installations that the cell is
installed on a bypass equipped with isolation valves,
see Figure 3 and Figure 4.
• In order to avoid load loss, installing the cell on a
bypass is MANDATORY if system flow rate exceeds
18m
3
/hr, see Figure 3 and Figure 4.
• If installing on a bypass, use a downstream check
valve instead of a manual valve to prevent improper
back flow into the cell.
