Installation And Start-Up; Maintenance - Atlas Filtri DOSAPROP Handbuch

ENGLISH
DOSAPROP and DOSAFOS
DOSAPROP and DOSAFOS are anti-scale water conditioning units designed for the dosage of polyphosphate for the protection of
water-heaters, boilers and other home appliances against the formation of calcareous incrustations causing reduction of heating
efficiency, and against corrosion of pipes and tubes. DOSAPROP are proportional dosing units, which, thanks to Venturi effect, keeps
the polyphosphate dissolved in water below 5 mg/l at any time.
General direction for use
- Use only for filtration of water with pH from 6.5 to 9.5.
- In case of use for drinking water, use only DOSAPROP proportional polyphosphate dosing units.
- Do not use with unsafe water or with water of unknown quality without adequate disinfection before or after the filter.
- Keep protected from light.
- Keep protected from back-flows with a non-return valve.
- Keep protected with a pressure-reducer device, if pressure exeeds the working pressure indicated in the product sticker.
- Keep protected from water hammer with an anti-water hammer device (expansion vessel). See Installation lay-out for applicable
devices (Fig. C).
- Do not install near to electric appliances.
WARNING
- Respect the working conditions as shown in the sticker affixed to the product.
- If the sticker is tampered, damaged, not legible or missing, applicable working conditions are: max pressure 8 bar, max temperature
35°C, max water total hardness 50°f (500 ppm CaCO
Installation guidelines
WARNING
- Before the installation, carefully lubricate the housing o-ring which is located at the bowl top. Ask your vendor for original lubricant
Lubrikit.
- Before the installation, check if the hydraulic system has been set-up according to the rules-of-the art in force.
- Install the products in sheltered rooms and protected from freeze and excessive heat.
Refer to figures:
A Applicable sealant and applicable fittings.
B IN-OUT directions presentation and vent-valve (VV) location.

Installation and start-up

- Turn-off water mains.
- Avoid all kind of tensions by using original wall brackets as a support (ask your vendor for original ones if not included).
- The installation of a by-pass is recommended.
- Connect the inlet to the product's side with the indication IN and the outlet to the side with the indication OUT.
- Connect to pipes using cylindrical (parallel) fittings (BSP - ISO 228), possibly with flexible hoses.
- Connect to tapered (conical) fittings (ANSI/ASME B1.20.1) only if the product is marked with NPT on head, possibly with flexible
hoses.
- Use only sealing tape as a sealant for the connections.
- Turn-on water mains.
- Unscrew the vent-valve and wait for air purge, then screw and tighten the vent-valve.
WARNING
Make sure that there are no water leaks from the product, and especially control the tightening between the housing head and the
housing bowl. Continue checking that the tightening is good and there is no water leakage for 48 hours following the Installation and
start-up. In case of leakage, open the housing, remove the o-ring from the bowl, place a new o-ring and apply original lubricant
Lubrikit, then re-tighten the bowl to head and repeat the leakage check as above. Use only original Atlas Filtri o-rings otherwise the
warranty is void. Ask your vendor for original o-rings, Lubrikit and other spare parts.
> Remark: after the installation, slowly turn on a water supply (tap) downstream the installed unit and let the water flow for at least
5 minutes before the use.

Maintenance

WARNING
The polyphosphate refill MUST be changed every 6 months, unless it is consumed before, with a new polyphosphate refill.
Do not use any of the old refill in refilling the dosing system. Dispose all of the old refill, following the regulation for
disposition in force.
- Periodically clean the housing with cold water and a soft sponge. Replace the housing bowl every 5 years at least.
- For DOSAPROP models, by using a needle periodically clean the nozzle at the inner side of the head.
- If not in use for long time: remove the polyphosphate cartridge or polyphosphate charge; at re-starting: use a new polyphosphate
cartridge or a new polyphosphate charge.
WARNING
At re-start after every maintenance operation and/or refill change, when the unit's bowl is unscrewed from head, change the o-ring
with a new one and carefully lubricate with original lubricant Lubrikit before tightening the bowl to the head. Make sure that there
are no water leaks from the product, and especially control the tightening between the housing head and the housing bowl. Continue
checking that the tightening is good and there is no water leakage for 48 hours following the Installation and start-up. In case of
leakage, open the housing, remove the o-ring from the bowl, place a new o-ring and apply lubricant, then re-tighten the bowl to
head and repeat the leakage check as above. Use only original Atlas Filtri o-rings otherwise the warranty is void. Ask your Vendor for
original o-rings, Lubrikit and other spare parts.
> Remark: after the maintenance, slowly turn on a water supply (tap) downstream the installed unit and let the water flow for at
least 5 minutes before the use.
Polyphosphate refill replacement
Check form Figure D for the dosing unit model:
D1- dosing unit with polyphosphate cartridge; D2- dosing unit with loose polyphosphate and diffuser tube.
Follow regulations in force for the disposal of used polyphosphate refills.
1. Before opening the housing turn-off water mains.
2. Release the pressure from the product by un-screwing the vent-valve.
3. Open the housing unscrewing the bowl from head.
4. Remove the used polyphosphate refill.
5. Wipe clean the filter housing with cold water and a soft sponge. In the case of dosing unit with loose polyphosphate, make sure
to remove and discard all the polyphosphate; keep the diffuser tube for next use.
6. Insert the new polyphosphate refill into the unit housing: a. in case of dosing units with polyphosphate cartridge, discard the
cartridge plastic wrap before placing it inside the unit housing; b. in case of dosing units with loose polyphosphate (supplied in
dedicated packs) pour the polyphosphate crystals from the refill pack, making sure the diffuser tube in the middle of the housing
is standing right, and refill up to 5/6th of the length of the diffuser tube. Make sure NO polyphosphate part gets on the housing
o-ring, as it may affect the tightening.
7. Carefully read the leaflet/sticker of polyphosphate refills for directions and keep it for future reference.
8. Remove old o-ring from the bowl, insert a new o-ring and lubricate the o-ring with original LubriKit.
9. Tighten the housing bowl to the housing head using original spanners. Do not over-tighten.
10. Turn-on water mains.
11. Wait for air purge from the vent-valve, then screw and tighten the vent-valve.
> Remark: after operation, slowly turn on a water supply (tap) downstream the installed unit and let the water flow for at least 5
minutes before the use.
ATTENTION: using polyphosphate refills different from the Atlas Filtri original ones make the warranty void - Ask your vendor for
original polyphosphate refills. The ranges of original polyphosphate refills are available on www.atlasfiltri.com
