We encourage Culligan users to learn about Culligan products, but
we believe that product knowledge is best obtained by consulting
with your Culligan dealer. Untrained individuals who use this manual
assume the risk of any resulting property damage or personal injury.

WARNING - Prior to servicing equipment, disconnect
power supply to prevent electrical shock.

CAUTION: Do not use with water that is microbiologically

unsafe or of unknown quality without adequate disinfection
before or after the system.

WARNING: IF INCORRECTLY INST ALLED, OPERA TED OR

MAINT AINED, THIS PRODUCT CAN CAUSE SEVERE INJURY .
THOSE WHO INSTALL, OPERATE, OR MAINTAIN THIS
PRODUCT SHOULD BE TRAINED IN ITS PROPER USE, WARNED
OF ITS DANGERS, AND SHOULD READ THE ENTIRE MANUAL

Introduction

MG10 R/O WATER FILTRATION SYSTEM

Culligan® Aqua-Cleer® Series BXL and BXL Plus reverse osmosis systems are designed to meet the needs of
applications for high quality water. This manual contains important information about the unit, including informa­tion needed for installation, operating, and maintenance procedures. A troubleshooting section provides a guide
for quick and accurate problem solving.

In order for the water treatment system to continue to provide high quality water, a thorough understanding of the
system and its operation is required. Review this manual before making any attempt to install, operate or service the
system. Installation or maintenance done on this system by an untrained service person can cause major equipment
or property damage.

This publication is based on information available when approved for printing. Continuing design refinements
could cause changes that may not be included in this publication.

SAFE PRACTICES

Throughout this manual there are paragraphs set off by special headings.

NOTICE: Notice is used to emphasize installation, operation or maintenance information which is important, but
does not present any hazard.

Example: NOTICE: The nipple must extend no more than 1 inch above the cover plate.

CAUTION: Caution is used when failure to follow directions could result in damage to equipment or

property. Example:

CAUTION: Disassembly while under water pressure can result in flooding.

WARNING: Warning is used to indicate a hazard which could cause injury or death if ignored. Example:

WARNING! ELECTRICAL SHOCK HAZARD! UNPLUG THE UNIT BEFORE
REMOVING THE TIMER MECHANISM OR COVER PLA TES!

The CAUTION and WARNING paragraphs are not meant to cover all possible conditions and situations that may
occur. It must be understood that common sense, caution, and careful attention are conditions which cannot be
built into the equipment. These MUST be supplied by the personnel installing, operating or maintaining the
system.

Be sure to check and follow the applicable plumbing codes and ordinances when installing this equipment. Local
codes may prohibit the discharge of acid or caustic solutions to drain. An extra solution tank should be used to
neutralize the solution before discharging to drain.

Use protective clothing and proper face or eye protection equipment when handling chemicals or power tools.

SERIAL NUMBERS

The Culligan Series BXL system has two serial number labels, one for the entire plumbing assembly and one for the
RO module assembly. The plumbing assembly serial number label is located on the top right-side of the panel. The
RO module serial number is located on the modules. Do not remove or destroy these serial number labels.
They must be referenced for warranty parts replacement.

REVERSE OSMOSIS

In order to understand reverse osmosis, we must first define osmosis. Osmosis is the passage of a liquid through a
semi-permeable membrane. A semi-permeable membrane is a membrane which allows one component of a solution

2 AQUA-CLEER SERIES BXL AND BXL PLUS

to pass through it and not the others. In osmosis, there is a tendency for a liquid to go from an area of less

MG10 R/O WATER FILTRATION SYSTEM

concentration to an area of more concentration through a semi-permeable membrane. Figure 1 shows the osmotic
process.

If pressure is applied to the concentrated solution, reverse osmosis will take place. The pressure causes a flow
through the semi-permeable membrane into the dilute solution. The semi-permeable membrane acts as a barrier to
ions and does not allow them to pass through into the dilute solution. When applied to water, this means that the
product water has a reduced total dissolved solids (TDS) content as a result of the passage of water molecules
through the membrane while the mineral ions are rejected. (Figure 2)

Note: Numbers used in these examples may not reflect those of your unit.

FIG. 1 FIG. 2

REJECTION AND RECOVERY

Feed water entering the system is split into two streams, a product stream and a concentrate stream (Figure 3).

During the process of reverse osmosis, some of the water has its dissolved solids content reduced by approximately
96%. This high quality product water is sent to service.

FIG. 3

The rest of the feed water contains the total dissolved solids removed from the product water, in addition to the
total dissolved solids already present in the feed water. This concentrate water is sent to drain.

The amount of total dissolved solids rejected by the system is expressed as a percentage. A 90% rejection means
that 90% of the total dissolved solids have been removed from the feed water by the system. To calculate the
percent rejection, use the following equation:

(Feed TDS - Product TDS)

Feed TDS

x 100 = % Rejection

where Feed TDS is the total dissolved solids content of the water going into the system, and Product TDS is the
total dissolved solids content of the high quality product water.

Example - If the Feed TDS is 600 ppm and the Product TDS is 24 ppm.

(600 - 24)

The amount of high quality water recovered for use as a percentage of the water fed into the reverse osmosis system
is called percent recovery . Use the following equation to calculate percent recovery:

Product Water Flow Rate

Feed Water Flow Rate

x 100 = 96% Rejection

600

x 100 = % Recovery

INTRODUCTION 3

NOTICE: The feed water flow rate is equal to the product water flow rate plus the concentrate water flow rate,

MG10 R/O WATER FILTRATION SYSTEM

both of which are easily measured.

Example - If the product flow rate is 0.7 gallons per minute and the concentrate flow rate is 0.55 gallons per minute,

0.7

x 100 = 56% Recovery

(0.7 + 0.55)

CAUTION: An understanding of rejection/recovery percentages is essential for

monitoring and evaluating the performance or condition of the reverse osmosis
system. DO NOT operate the system before becoming familiar with these concepts.

FEED WATER LIMITS

Before starting the installation, verify that the feed water meets the limits shown in T able 1, and that a water softener
is used for pretreatment.

TABLE 1 - FEED WATER LIMITS

Property Minimum Maximum

Turbidity (NTU) 0.0 1.0
pH* 6 11
Chlorine (ppm) 0.0 0.1
Total Dissolved Solids (ppm) 50 2500
Temperature (°F) 33 100
Silt Density Index 0.0 5.0
Iron (ppm) 0.0 1.0

* Short term cleaning is acceptable for pH ranges between 2.0 and 12.0. Additional treatment is required when
chloramines are present and the pH levels exceed 9.0.

NOTICE: In some applications, a water softener is not required. Consult the independently operated Culligan

dealer for further information on these special applications.
