dosatron D25BL Series Quick Start-Up

PRECAUTIONS
1- GENERAL REMARKS
- When connecting a DOSATRON either to the public water supply or to its own
water source, you must respect the regulations in force concerning protection of
the source i.e. backflow prevention, etc.
- When connecting the DOSATRON to the water supply, ensure that the water
flows in the direction of the arrows on the unit.
- In a case where the water installation is higher than the DOSATRON itself, there
is a possible risk of water and concentrate flowing back through the DOSATRON.
In this case, installing a non-return valve downstream is recommended.
- It is recommended that you should place an anti-siphon valve on the downstream
side of the dosing pump in installations in which there is a risk of siphoning.
- Do not install the DOSATRON just above an acid container, (risk of acid fumes
attacking the DOSATRON) and protect it from possible contact with corrosive
products.
- Protect the DOSATRON from freezing temperatures by draining it and store it
away from sources of excessive heat.
- Do not install the DOSATRON on the suction side of the supply pump (risk of
siphoning).
- It is the responsibility of the owner/operator to replace the injection seals
annually to ensure precise injection.
- The setting of the Dosatron's dosing rate is the sole responsibility of the user.
The user has to respect the recommendations given by the manufacturer of the
chemical product.
WARNING
You must comply with the safety instructions when installing, using and
performing maintenance on the DOSATRON water-powered dosing pump: use
appropriate tools, protective clothing and safety goggles when working on the
equipment and install the DOSATRON so that it can be used without presenting
a risk.
Follow the instructions in this documentation and take the appropriate safety
measures for the water temperature and the type of liquid being drawn up. Take
extreme care when using dangerous substances (solvents, acids, and corrosive,
toxic, caustic and inflammable substances, etc.).
- For dosing of these substances, consult with your distributor before use in order
to confirm they are compatible with your dosing pump.
A dosing pump with the option 'T' is required when installing the DOSATRON on
a hot-water supply (60°C/140°F Max).
The higher temperature increases the risk and danger of the aforementioned
substances.
It is strongly recommended that you place signs on the dosing pump and the hot-
water installation warning of this risk and that you comply with legislation in force.
WARNING! Personnel in charge of installing, using and maintaining this
equipment must read this documentation.
PRECAUTIONS
- It is the responsibility of the owner/operator to check that the flow and pressure
of the installation do not exceed the DOSATRON characteristics.
- Adjustmentmust be made when there is no pressure in the Dosatron. Turn off
the water supply and allow the pressure to drop to zero.
- It is the responsibility of the owner/operator of the DOSATRON, to determine
the correct amount of solution and injection ratio to obtain the desired result.
- An air inlet, an impurity or a chemical attack on seal can interrupt the dosing
function. It is recommended to periodically check that the solution is being
correctly drawn up into the DOSATRON.
- Change the suction tube as soon as it seems damaged by the chemical.
- Relieve the pressure after use (advised).
- Rinsing of the DOSATRON is required :
. when changing chemicals,
. before handling the DOSATRON, to avoid any contact with the chemical.
- All assembly should be done without tool, hand tighten only.
2- WATER WITH HIGH PARTICLE CONTENT
- A (ex.: 300 mesh - 60 microns depending on your water quality) water filter must
be installed prior to the DOSATRON (see accessories), if a filter is not installed
abrasive substances will cause the DOSATRON to deteriorate prematurely.
3- WATER-HAMMER / EXCESSIVE FLOW
- For installations subject to water hammer a protection device such as a check
valve or union ball check must be fitted (pressure/flow control system).
- For automatic installations, slow opening and closing solenoid valves are
preferable.
- In an installation where a DOSATRON serves several sectors, the closing of
one sector and the opening of another sector must be done at the same time
(simultaneous operation of the solenoid valves).
4- INSTALLATION LOCATION
- The location of the DOSATRON and concentrate container should be
accessible, but should never present a risk of pollution or contamination.
- It is recommended to label all water lines with a warning about the injected
solution i.e. Not For Human Consumption.
5- MAINTENANCE
- Rinse the injection areas after using the DOSATRON. To do this, insert suction
tube into container of clean water (~ 1 liter [0.264.US GALLONS]).
- Routine maintenance once a year will add to the life of your DOSATRON.
Replace the dosing seals as well as the suction tube annually to ensure proper
injection.
6- SERVICE
- Complete maintenance and seal kits are available.
- Call your DOSATRON distributor for service or parts.
