POOLWARDEN INSTALLATION
Mounting PoolWarden
Turn off any heaters, pool or spa circulation systems, chemical feed pumps or any related shut-off valves or
equipment and relieve pressure from the filtration system. Find a suitable mounting location near a 120/220
VAC power source that meets the following criteria:
⧫
Facilitates a combined (influent & effluent) maximum tubing run of 30’.
⧫
Do not mount controller above electrical sources or electrical equipment.
⧫
At least 10’ away from any pool, spa or body of water and not accessible to the public.
⧫
Away from corrosive materials and physical hazards.
⧫
Not in direct sunlight or directly above or near any heat source.
⧫
For 220 VAC, ability to hard wire with GFCI (ground fault circuit interrupter) protection.
Securely mount controller, or the optional controller backboard, vertically on the wall using supplied screws or
appropriate fasteners for the wall construction. Never mount MiniWarden horizontally.
Flow Cell To Circulation Plumbing
There are many ways to connect the flow cell tubing to the circulation plumbing. Always make sure the input
source to the flow cell is well upstream from any chemical injection points. Successful flow cell installation
requires a pressure differential, or there will be no water flowing through the cell. The Flow cell input should be
filtered water and therefore after the filter. Never install the input to the flow cell between the main circulation
pump and filter as that will be very high pressure which may damage the pump and provide the most debris to
the flow cell. PoolWarden is equipped with a strainer to filter out any debris that does get past the filter.
Periodically check and clean the strainer. Install the flow cell return after the heater, there will be a pressure
drop across that should be sufficient to provide flow through the flow cell. If there is no heater, the next choice
is the suction plug in the pumps strainer, make sure to adjust the return valve on the flow cell to keep the
pressure in the flow cell positive.
⧫
Flow Cell Input: Drill & tap a connection point in the circulation system at a location just after the filter. The
best location is where there is a pipe fitting as that will provide the most threads. Install a tube connector
and run tubing to the input side of the flow cell.
⧫
Flow Cell Output: Drill & tap a connection point in the circulation system at a location with reduced
pressure just after the heater. Install a tube connector and run tubing to the return side of the flow cell.
CAUTION
: Maximum pressure across the sensors should be 10 PSI (pressure gauge may be required).
Always expose the sensors to positive pressure. Prevent exposing the sensors to suction or a vacuum by
connecting the flow cell output tubing to the suction side of the pump as the vacuum may suck the sensor gel
from the sensors rendering the sensors inoperable in a very short period of time.
⧫
If not pre-mounted, find a suitable location to mount the acrylic flow cell within 3 feet of the controller.
Mount and assemble flow cell parts according to Picture 2.
⧫
Remove pH (Blue) and ORP (Red) sensors from the boxes. Use Teflon tape on sensor threads and all
other flow cell parts to ensure water tight connection and fasten accordingly.
⧫
Install the appropriate 1/2” or 3/8” hard vinyl input and output tubing from the pools circulation system
connection points to the “In” and “Out” connection points on the flow cell according to Picture 2.
⧫
Once connected, turn circulating pump back on, test for leaks at all connection points, and make sure all air
evacuates form the tubing.
⧫
There is a small magnet in the flow cell that is held in place with a piece of tape. Remove the tape and
make sure the magnet remains in the hole above the filter / strainer.
