Attention

BRITA-PURITY-450-Steam-Water-Filter-System-02

The PURITY replacement cartridge may only be used in combination with the pressure vessel that has been specifically designed for its size.

General Information

Function and Application
The BRITA PURITY Steam water filter system optimizes tap water specially for combi ovens and conventional ovens. It decarbonates drinking water, thereby reducing scale deposits in and on the terminal equipment. Depending on the bypass setting, calcium and magnesium ions as well as heavy metal ions such as lead and copper are selectively removed from the drinking water. In addition, the filter material not only reduces cloudiness and organic impurities but also substances that impair smell and taste, such as chlorine residues.
The bypass setting, which is specially designed for combi ovens and conventional ovens, matches the reduction in the carbonate hardness to the local water hardness in order to achieve an optimum filtrate quality. The increased flow and the reduced pressure loss enable the smooth operation of the combi oven.
The filter systems are available in three different filter system sizes (PURITY 450 Steam, PURITY 600 Steam and PURITY 1200 Steam), each in a version without integrated measuring and display electronics or with measuring and display electronics (Advanced Control System, ACS Technology). Filter systems with ACS Technology show you the current remaining capacity and bypass setting of your filter cartridge, the set type and size of the filter system and the last replacement date of the filter cartridge. This ensures optimum filter control and water filtrate quality. Further information on the filter system with ACS Technology can be found in Chapter 5.2.

Specific Safety Information

Only water of drinking water quality may be used as intake water for the BRITA water filter system. The BRITA water filter system is only suitable for cold water use within the water intake temperature stated in Chapter 12. No microbiologically impaired water or water of unknown quality may be used without prior appropriate disinfection.
If there are official instructions to boil tap water, the filter system must be decommissioned. When the requirement to boil water comes to an end, the filter cartridge must be replaced and the connections cleaned.
Note for people with kidney disease or dialysis patients: During the filter process the potassium content may be increased slightly. If you suffer from kidney disease and/or have to stick to a special potassium diet, we recommend prior agreement with your doctor.
The water filtrate is classified in Category 2 according to DIN EN 1717.
BRITA recommends that the filter system not be decommissioned for a long period. If the BRITA PURITY Steam filter system is not used for several days (two to three days), we recommend that the filter system be flushed with at least X liters according to the table below. After stagnation periods of over four weeks, the filter should be flushed with at least Y litres or else replaced. Please also note that the maximum usage period of the filter cartridge is twelve months (Chapter 6).
Filter system| Flush quantity X after 2–3 days stagnation| Flush quantity Y after 4 weeks stagnation
---|---|---
PURITY 450 Steam| 6 litres| 30 litres
PURITY 600 Steam| 12 litres| 60 litres
PURITY 1200 Steam| 24 litres| 120 litres
The filter system is not resistant to heavily concentrated cleaning agents (e.g. bleach, chlorinated solvents, heavy oxidants) and must not come into contact with them.
The filter system must not be opened or dismantled during operation. The filter cartridge must not be opened.
The pressure vessel and the pressure vessel lid of the filter systems have a service life of up to ten years (from the date of installation), provided that they are installed and used correctly and the operating conditions outlined in the Technical Data chapter are adhered to.

Safety Assembly Instructions

The terminal device operated with the filter must be free of limescale prior to installation. Protect the filter system from sunlight and mechanical damage. Do not assemble near of heat and open flames.
A stop valve must be installed before the filter system intake hose.
If the water pressure is higher than 6.9 bar or if there are statutory requirements, a pressure reducer must be installed before the filter system.
A non-return valve tested by the DVGW has been factory-installed at the water intake of the filter head.
No copper pipes and no galvanized or nickel-plated pipes/connectors may be installed between the water filter and the consumer. The use of BRITA hose sets is recommended here. When choosing the material for parts that come into contact with water after the BRITA filter system it must be remembered that, due to the process, decarbonized water contains free carbon dioxide.
All parts must be installed in accordance with the country-specific guidelines on the installation of drinking water facilities.
For erection and operation of the filter system, the BG rules “Working in Kitchens” of the Specialist Committee “Foods” of the BGZ (BGR111) must be observed.

Product Installation

Caution: Prior to installation, read the Technical Data (Chapter 12) and the Operating and Safety Information (Chapter 3). After the product has been stored and transported at temperatures below 0°C, it must be stored with the original packaging open for at least 24 hours at ambient temperature (Chapter 12) before commissioning.

Delivery Scope
Prior to installation, remove the entire delivery scope from the packaging and check that everything is present:

1 x Pressure Vessel 1
1 x Pressure Vessel Lid 3
1 x Filter Cartridge 2
1 x Manual
1 x Carbonate Hardness Test
1 x Sticker for Service Pass (orange)
1 x Adapter 1″–3/4″

If parts of the delivery scope are missing, please contact your local BRITA office (see the back of the cover).

Assembling the Pressure Vessel and the Pressure Vessel Lid

Stand with both feet on the kick loops 12 .
Lift the pressure vessel 1 and turn it clockwise until the mantle handles 16 are over the kick loops 12 .
Remove the transport protective cap 18 from the filter cartridge.
Check that the O-ring seal of the filter cartridge 2 is correctly seated in the groove and also check for dirt and damage.
Note: lubricant at the factory.
Stand on the kick loops 12 with both feet and place the pressure vessel lid 3 on the pressure vessel 1 . The position of the arrow marking on the lid handle 20 must match the “INSERT” groove.
Press the pressure vessel lid 3 down and turn clockwise until the lock 15 engages.

Assembly of Inlet and Outlet Hoses inlet and outlet hoses are not included in the standard scope of delivery.
The use of BRITA hose sets is recommended (Chapter 13).

Fit inlet hose 6 at the inlet of the connector head 4 and outlet hose 10 at the outlet of the connector head 4 .
Note: Inlet “IN” and outlet “OUT” of the connector head 4 are equipped with O-rings as seals, therefore no additional flat seals may be used here. Check that the O-rings are seated correctly.
Caution: The max. tightening torque at the 1″ and 3/4″ connections must not exceed 15 Nm! Only hose connections with flat seals may be used. Hoses with conical screwed connections dam-age the filter head connections and invalidate any guarantee claims. Only hoses that comply with DVGW-W 543 may be used to connect the device.
Before assembly, note the direction of flow on the upper side of the filter head, “IN” = water inlet, “OUT” = water outlet. Prior to installation, note installation dimensions and operating position (Chap-ter 12). If no original hoses are used, the 1″–3/4″ 17 adapter supplied must be used to ensure the return valve is sealed correctly (pre-fitted in the water inlet).

Commissioning a New Filter

The bypass position can be adjusted to the local water quality or the machine type.

The following recommendations for bypass settings apply by default:

Position 0: All devices in areas with an extremely high water hardness level (> KH = 22 °KH).
Position 1: Combi ovens and conventional ovens with direct injection system
Position 2: Combi ovens and conventional ovens with boiler system
Position 3: All devices in soft water areas (< KH = 7 °KH).

You can obtain individual recommendations from your BRITA contact.
Note: The stated capacities have been tested and calculated on the basis of common application and machine conditions. External factors (such as fluctuating crude water quality and/or machine type) can cause deviations from this information.

Repair

Regularly check the filter system for leaks. Regularly check the hoses for kinks. Bent hoses must be replaced.
The complete filter system must be replaced in rotation after a maximum of ten years.
The hoses must be replaced in rotation after a maximum of five years.
