INSTALLING THE DOSATRON UNIT (Cont.)
Threaded connection
The D132GL unit features a 3" NPT thread male connector. Before screwing it
to your water supply system, make sure that you apply sealing tape/compound
to the threads of the DOSATRON regulator.

INSTALLATION HINTS

The DOSATRON is delivered with a suction tube (cut it to the needed
length) enabling its use with a large capacity concentrate container.
The tube must be fitted with its strainer and weights.
The instructions for fitting the tube are to be found on page 50.
NOTE : The maximum suction height is 4 meters (13 vertical feet).
Fit the tube, equipped with its strainer and its weight, and immerse it in the
concentrate solution to be injected.
IMPORTANT ! - Do not put the suction tube strainer on the bottom of
the stock solution container. The strainer must be suspended at least 4"
[10cm] above the bottom of the tank to avoid sucking up the insoluble
particles that may damage the injection assembly (Fig.2).
- Do not put the strainer on the bottom.

WHAT YOU SHOULD DO
Under no circumstance should the
solution level be above the water inlet
of the DOSATRON (to avoid sipho-
ning situations).
The DOSATRON can be connected to
the main water line directly (Fig. 2A),
recommended.
If your flow rate is above the operating
limits of the DOSATRON, see
EXCESSIVE FLOW.
To prolong the working life of the
DOSATRON it is advisable to install
a filter (ex.: 200-120 mesh - 80-130
microns depending on your water
quality) upstream.
This is imperative if the water contains
impurities or particles, especially if the
water comes from a well.
A filter is recommended and
required for the warranty to be valid.
EXCESSIVE FLOW (as an indication)
If your DOSATRON clicks more than 46 times, that is 23 cycles in 15 seconds,
you are close to the superior flow limit. If you need more flow, you must install a
DOSATRON with a superior capacity of flow (please ask advice).
