Basic Principles 3
Cat. No. 01024514
Basic Principles
Activated Carbon Filter
Filters reduce unpleasant taste and odors from the water supply. In normal operation, the water passes through the multi-
port valve into the top of the media tank. As it flow down through the mineral bed, sediment in the water is filtered out and
objectionable dissolved gases are absorbed into the mineral. The clear water that leaves the bottom of the media tank and
goes into the service lines is free from many disagreeable taste and odors.
Depth Filter
Depth filters filter both heavy sediment and suspended matter from the water supply. In normal operation, the water pass-
es through the multi-port valve and into the top of the media tank. As the water flows down through the mineral bed, sed-
iment in the water is filtered out. The clear water that leaves the bottom of the media tank and flows through the service
lines is free from most sediment and suspended matter.
Greensand Filter*
Culligan’s standard Greensand Filters operate as a continuous feed system similiar to a depth filter and not as a batch
style system. Greensand can remove manganese and both oxidized and soluble iron using a chlorine-injection feed
system ahead of the filter. Reconditioning frequency is dependent on filter loading, but a maximum chlorine demand of
10 mg/L is recommended. Desludging tanks or alternative methods of reducing the chlorine dosing may be required. This
system is not recommended for removing high levels of sulfur.
Filtering Process
To keep the filter operating properly, it is necessary to periodically remove the accumulated sediment from the mineral
bed. This done by a three-step process:
Backwash
The direction of flow through the tank is reversed, and the mineral bed is backwashed. This action expands and agitates
the bed, releasing the sediment that is then carried up and out to the drain.
Settle
The tank is allowed to be in an idle state to tallow the different types of media to stratisfy and settle. Water flow to the
drain will be present during this step.
Fast Rinse
A rapid downflow flush repacks the mineral bed and washes out traces of sediment not removed by backwash.
Backwash Frequency
Generally, backwash the HE 1.5 filter once per week. However, more frequent cleaning is recommended for water with
high turbidity. On filters with pressure gauges, the differential pressure across the filter can be monitored.
Carbon, depth and greensand filters should be cleaned when the differential pressure across the filter increases by 8–10
psi over the pressure differential across a clean filter bed.
*Greensand filters are not WQA or IAMPO certified.

4 Culligan® High Efficiency 1.5 Water Filter 4 Cat. No. 01024514
Performance Specifications
In order to function properly, some operational parameters must be followed. They include:
1. An operating water pressure between 20 and 125 psi (138-862 kPa). If water pressure is greater than 80 psi, Culligan
recommends following the IAPMO Uniform Plumbing code section 806.2 by installing a Pressure Regulating Valve
before the system. Operating on high presure for extended periods of time can increase the service frequency of re-
placement parts. If water pressure can drop below the minimum water pressure, add a booster pump to maintain a
25 psi (172 kPa) minimum operating pressure.
2. Operating temperature between 33° and 120°F or 1°–49°C.
3. Clear (non-turbid) water supplies (Less than 5 NTU).

Application
Water Quality
Verify that raw water and flow rate are within limits as outlined in the specifications.
CAUTION! Do not use where the water is microbiologically unsafe or with water of unknown
quality without adequate disinfection before or after the unit.
Pressure
If pressure exceeds 125 psi (860 kPa), install a pressure reducing valve (see materials checklist). On private water sys-
tems, make sure the minimum pressure (the pressure at which the pump starts) is greater than 20 psi (140 kPa). Adjust
the pressure switch if necessary.
CAUTION! The use of a pressure reducing valve may limit the flow of water in the household.
Temperature
Do not install the unit where it might freeze, or next to a water heater or furnace or in direct sunlight. Outdoor installation is
not recommended and voids the warranty. Use the Culligan Outdoor HE filter for outdoor installations. The Culligan Out-
door HE filter has been certified by Underwriter’s Laboratories for outdoor installation. If installing in an outside location,
you must take the steps necessary to assure the filter, installation plumbing, wiring, etc. are as well protected from the
elements (sunlight, rain, wind, heat, cold), contamination, vandalism, etc. as when installed indoors.
Location
Space Requirements
Allow 6–12 inches (15–30 cm) behind the unit for plumbing and drain lines and 4 feet (1.3 meters) above the unit for
service access.
Floor Surface
Choose an area with solid, level floor free of bumps or irregularities. Bumps, cracks, stones and other irregularities can
cause the salt storage tank bottom to crack when filled with salt and water.
Drain Facilities
Choose a nearby drain that can handle the rated drain flow (floor drain, sink or stand pipe). Refer to the Drain Line Chart,
Table 3 on page 18, for maximum drain line length.
NOTE Most codes require an anti-siphon device or airgap. Observe all local plumbing codes and drain
restrictions. The system and installation must comply with all state and local laws and regulations.
Electrical Facilities
A 10-foot cord and wall mount plug-in transformer are provided. The customer should provide a receptacle, preferably one
not controlled by a switch that can be turned off accidentally. Observe local electrical codes.

The Smart Controller uses a circuit board designed to mount onto the control valve attached to a water softener or filter.
There are four other, optional, add-on modules in the Smart Controller family. These modules include:
Wireless Remote Control
This remote control displays the current status of the water softener or filters and allows for remote control. It can be
located up to 200 feet away from the Smart Controller (depending upon building construction materials).
Modem Board
This module can be installed into either the Smart Controller or the Wireless Remote. It allows for the system to be re-
motely monitored detecting problems before they occur.
NOTE Modem kit requires a one-year subscription to either Level 1 or Level 2 Telecom package. See on
C-Port (www.cport.culligan.com) under the Telemetry Tab for details.
RF Transmitter
This module is installed into BOTH the Smart Controller and the Wireless Remote to allow them to communicate via
Radio Frequency (RF) communications. In North America, these modules communicate at 915 MHz and are designed to
work without interference with other 915
MHz devices such as cordless telephones
and baby monitors. Other frequencies are
used in other countries.
Auxiliary Board
This module can be installed into the
Smart Controller to provide a variety of
add-on capabilities such as operation of
external solenoid valves and relays(typi-
cally used in commercial applications).
Flow Meter
The High Efficiency filter can monitor any
hall-effect type flow meter signal and use
it as the basis of monitoring the amount of
water flowing through the valve.

Notes for preparing Greensand filters* for service:
1. Before adding the last Cullcite (anthracite) layer backwash the existing media including the Cullsorb for 10
minutes or until the water is clear at the drain. Then stop the backwash, depressurize the system and drain the
water down to within 3 - 4 inches above the media.
2. For every cubic foot of Culsorb media to be treated mix 0.5 gallons of 5.75% Chlorine Bleach or 0.2 gallons of
12% Sodium Hypochlorite into 6.5 gallons of water. Pour the chlorine mixture into the tank and allow it to soad
for a minimum of 4 hours.
3. Re-pressurize the unit, fill with water and rinse the media until the free chlorine residual at the drain is less than
0.2 mg/L.
4. Depressurize the unit and drain down the water and add the final Cullcite (anthracite layer. Fill with water and
initiate a complete backwash and rinse cycle.
5. The unit is now ready for operation.
*Greensand filters are not WQA or IAMPO certified.

Straight-Through Adapter
Each filter is shipped with a Culligan® straight-through adapter to connect the filter to the plumbing system.
CAUTION! Close the inlet supply line and relieve the system pressure before cutting into
the plumbing! Flooding could result if not done!
Straight-Through Adapter Installation
Refer to Figure 15 and the instructions below to connect the
meter, straight-through adapter, and interconnecting pipe.
1. All HE 1.5 units are equipped with a meter. The
meter is installed on the outlet side of the control
valve. The meter body fits in the same space as the
coupling between the control valve and the straight
through adapter. Make sure the arrow on the flow
meter is pointing in the direction of the flow.
2. The straight-through adapter connects directly to
the control valve with the meter and coupling and
two assembly pins. Lubricate all O-rings on the cou-
plings/meter with silicone lubricant. See Figure 15.
NOTE The Low Flow Meter has a white dot on the
connection for the wire harness.
Figure 15. Straight-Through Adapter assembly.
NOTE If the ground from the electrical panel or breaker box to the water meter or underground copper pipe
is tied to the copper water lines and these lines are cut during installation of the straight-through
adapter, an approved grounding strap must be used between the two lines that have been cut in order
to maintain continuity. The length of the grounding strap will depend upon the number of units being
installed. In all cases where metal pipe was originally used and is later interrupted by the straight-
through adapter to maintain proper metallic pipe bonding, an approved ground clamp c/w not less
than #6 copper conductor must be used for continuity. Check your local electrical code for the correct
clamp and cable size.
CAUTION! Close the inlet supply line and relieve the system pressure before cutting into the
plumbing! Flooding could result if not done!
CAUTION! When making sweat connections, use care to keep heat away from the plastic nuts
used to connect the plumbing to the bypass. Damage to these components may result
otherwise.
