Installation Hints; Using For The First Time; Incorporated Hydraulic By-Pass - dosatron D8R Gebrauchsanweisung

INSTALLATION HINTS

The DOSATRON can be connected to
the main water line directly (Fig. 5) ;
on a by-pass (Fig. 6), recommended.
If your flow rate is above the opera-
ting limits of the DOSATRON, see §
EXCESSIVE FLOW.
To prolong the working life of the
DOSATRON it is advisable to install
a filter (ex.: 300 mesh - 60 microns
depending on your water quality)
upstream.
This is imperative if the water
contains impurities or particles, espe-
cially if the water comes from a well.

Excessive flow (as an indication)
If your DOSATRON clicks more than 36 times, that is 18 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.

A filter is recommended and requi-
red for the warranty to be valid.
Installing the DOSATRON on a
bypass enables clean water to be
supplied without operating the
DOSATRON and the DOSATRON to
be easily dismantled.
When connecting an
installation to the public water
supply, you must respect the
rules and regulations in force
in the country.

Putting the DOSATRON
into order

USING FOR THE FIRST TIME

- Place the by-pass lever in the ON
position (Fig.7-L).
- Open the water inlet valve slowly,
the DOSATRON is self-priming.
- Operate the DOSATRON until the
product to be injected is drawn up into
the injection stem (the product is visible through the plastic tube).
- The DOSATRON makes a characteristic "click-clack" noise when working.
NOTE : The time required to prime the suction hose depends on the water
flow-rate, the ratio setting and the length of the suction hose. To bleed the
air from the suction hose and accelerate the priming, set the injection rate
at maximum. Once the DOSATRON is primed, adjust to the required injec-
tion rate (see § ADJUSTING THE INJECTION RATE).

INCORPORATED HYDRAULIC BY-PASS

A mechanism to select either the dosing function or the by-pass mode :
The operating medium must have a minimum pressure of 0.8 bar [12 PSI]
in order to operate the by-pass.
- By-pass in OFF position (Fig. 8-L) : the DOSATRON is not working and is not
drawing up any concentrate.
- By-pass in ON position (Fig. 9-L) : the DOSATRON is sucking, injecting and
mixing concentrate into water at the desired percentage.

NOTE : When changing the lever (L) from the OFF to the ON position,
it is normal that a small jet of water escapes from the barbed fitting
ø 3 [1/8"] (Fig. 9-Q).
