Plumbing and Mounting
The cable connecting the Halo Doser to the Halo
Chlorinator is 1 m long, so the doser needs to be
located within 1 m of the chlorinator. See Figure 2.
The acid injection point (where the acid goes into the
pool water) must be mounted into the pipework, after
the chlorine cell and all other equipment. Ideally the
chamber should be mounted as far away as possible,
downstream from the chlorinator cell.
If probes are being fitted, then ideally the probe
mounting should be mounted as far away as possible,
upstream from the chlorinator cell.

Chlorinator Cell and Doser Installation
The Halo Doser should be located within 2 meters of
the acid injection point.
There are 6 separate mounting holes in the back plate
which gives a number of different options for screw
positions. Once a suitable position has been found,
mount the back plate to the wall using the two (2)
mounting screws (and masonry plugs if required).
Unclip the tinted visor from the doser assembly by
gently pulling it outwards at its base. Pull enough of
the dosing pump cable out of the pump enclosure to
reach the Halo Chlorinator and then push the pump
enclosure onto the wall mounting bracket (the cable
exits the doser assembly at the bottom – take care
not to pinch it!). Secure the doser assembly to the
mounting bracket using the two (2) mounting screws.

Flexible clear tubing is used
