Specifications
A OneFlow ® scale prevention system with added carbon filtra-
tion shall be installed on the cold water service line to condition
and filter 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 with added carbon filtra-
tion may also be installed to protect multiple pieces of equip-
ment from the ill-effects of hard water scale and taste/odor
concerns 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
housings to allow the bypass of untreated water in the event
that service or cartridge replacement is necessary. The instal-
lation area should be suitable in size for the housing to be ser-
viced without encumbrance and the system should be installed
per the Installation, Operation & Maintenance manual as pro-
vided 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.
