Preparation
Preparation 4
The success of the installation will depend to a great extent on advance planning and preparation. Careful attention to the unit’s
location, accessibility to electrical and drain facilities, and the availability of the proper tools will ensure a professional looking
installation. Of utmost importance is the assurance that the filter has been properly applied and meets all specifications.
Application
Correct application is directly associated with the performance and life expectancy of any water conditioner. It is important,
therefore, to understand how your Culligan
®
Water Filter functions, and to know its capabilities and limitations so that a correct
application can be made. By following the guidelines and recommendations set forth in this manual, you can be certain your
conditioner is applied correctly.
Filtr-Cleer
®
The Medallist Filtr-Cleer Water Filter is capable of reducing particulate matter down to 5 microns particle size. It will not remove
color, organics, colloidal turbidity or dissolved solids. Some applications follow:
• Reduction of suspended matters in any water system.
• Reduction of particulate matter, such as clay, mud, etc.
• Prefiltration of oxidized iron ahead of an automatic or manual softener.
• Reduction of light sand.
• After the retention tank when a Cul-Cleer
®
system is used to correct hydrogen sulfide or colloidal suspension problems.
The quality and number of gallons filtered water between backwashes will depend upon the amount, type, and size of the
particulate matter being filtered. If a water sample is sent to our laboratory, where application of a Filtr-Cleer unit is contemplated,
write “Filtr-Cleer Analysis” on the sample tag. Send an additional sample of water for a standard water analysis. The laboratory
will test for Nephelometric Turbidity Units (NTU) and suspended solids (mg/L). The sample will also be filtered through 10 micron
filter paper and NTU run on a filtered sample. If the NTU of the raw water exceeds 150, suspended solids exceed 150 mg/L or
the filtered water through the 10 micron filter paper is of an unacceptable quality, a Filtr-Cleer filter may not be applicable. As a
guide, the U.S. Public Health Drinking Water standards states the turbidity should not exceed 1 NTU. The exact number of gallons
filtered between backwashes cannot be given because of many variables.
Cullar
®
Filter
Medallist Water Filter with Cullar Media will reduce chlorine taste and odor and other common bad tastes and odors, and will also
remove most objectional organic colors. It will not remove hydrogen sulfide. It is important to note that whenever the cause of
an objectionable taste or odor has not been established, Health Authorities should determine if water is safe to drink. If bacterial
contamination is present, a Cul-Cleer system is indicated. Do not use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system.
Cullneu
®
Filter
Medallist Water Filter with Cullneu Media will neutralize slightly acid water (pH of 5.8 - 6.2) and thus help to prevent unsightly
brown or green stains due to corrosion of household plumbing. If the pH is from 5 to 6, one part of Cullneu C media should be
mixed with 5 parts of Cullneu media to provide additional neutralizing capability. If the water to be treated has a pH less than 5,
a high hardness, or a high carbon dioxide level, Cullneu may not be applicable; a solution feeder should be used. Since Cullneu
adds hardness, it should be used prior to a softener.
In order to size and apply the equipment correctly, a complete analysis of the water supply should be obtained. This can best be
accomplished by contacting the local Culligan dealer, who will be able to test the water supply right at the site, or arrange to have
one or more water samples sent to the Culligan laboratory for a more detailed analysis.
Culligan water filters may be applied alone or in conjunction with other equipment. They should only be applied, however, within
the specifications listed in this manual. These specifications establish the boundaries within which the conditioner will perform
most efficiently.
Note: If sands cannot be removed from the Filtr-Cleer tank during backwashing, a sand trap should be installed.
