The OneFlow

Anti-Scale System provides protection from

scale formation on internal and external plumbing surfaces.

The OneFlow

system is a single cartridge-based system

that must be installed on a cold water line prior to a water-

heating device (water heater or tankless water heater) for

single tankless heaters.

OneFlow

prevents scale by transforming dissolved hardness

minerals into harmless, inactive microscopic crystal particles.

These crystals stay suspended in the water and are passed

to drain. The system requires very little maintenance, no back-

washing, no salt and no electricity. Typical hardness problems,

especially build-up of scale in heating elements, pipes, water

heaters, boilers and on fixtures are no longer a concern.

OneFlow

is not a water softener. It does not add chemicals.

It is a scale prevention device with proven third party labora-

tory test data and years of successful commercial, residential

and food service applications. OneFlow

is the intelligent

scale solution and is a great alternative to water softening (ion

exchange) or scale sequestering devices.

Features

• Chemical-free scale prevention and protection - converts hard-

ness minerals to harmless, inactive microscopic crystals mak-

ing OneFlow

an effective alternative technology to a water

softener for the prevention of scale due to water hardness

• Virtually maintenance free - No salt bags or other chemicals

to constantly add or maintain

• No control valve, no electricity and no wastewater

• Uses environmentally friendly “green” technology

• Improves efficiency of all water heating devices and

downsream plumbing components.

• Simple sizing & installation – standard

/4" connections

• Perfect system for restaurants, cafeterias, coffee shops

and homes where multiple or single equipment protection

is desired for longer equipment life and reduced energy

consumption

• Inlet ball valve for easy isolation shutoff and filter changes

• OneFlow

cartridge-based systems are easily maintained;

change the cartridge once every two years

• Easily installed mounting bracket included w/filter wrench

to allow cartridge change-outs when necessary

Specifications

A OneFlow

scale prevention system shall be installed on the

cold water service line to condition the tap water just prior to

the service line feeding the equipment it is designed to protect.

The system will be sized for maximum or peak flow rate based

on the specification of said equipment. A OneFlow

system

may also be installed to protect multiple pieces of equipment

from the ill-effects of hard water scale provided the aggregate

peak flow rate for each piece of equipment it is protecting has

been considered. The system shall be plumbed with a bypass

valve to allow isolation of filter housing to allow the bypass of

untreated water in the event that service or cartridge replace-

ment be necessary. The installation area should be suitable in

size for the housing to be serviced without encumbrance and

the system should be installed per the Installation, Operation &

Maintenance manual as provided with each system.

The OneFlow

system must not require additional waste water

to backwash, flush, or regenerate once put into service. The

system shall not require any chemical additives and shall not

require electricity for operation.

Note: Copper lines need to be passivized for a minimum

of 4 weeks before placing unit into service. Not for use on

closed loop systems.
