Introduction 1
Cat. No. 01021716
Introduction
Thank you for purchasing the Culligan Executive Cooler. The Culligan Executive Cooler brings a unique, fresh approach
and a new look to point-of-use water treatment systems in the marketplace. The system’s contemporary color scheme
complements every office environment. Unlike a bottled water cooler, incoming tap water is treated as it is needed, so the
water is always fresh and great tasting. Best of all, there are no bottles to change and the supply is virtually unlimited.
The Culligan Executive Cooler is enhanced with BioCote® technology. BioCote® is a unique anti-microbial agent, based on
silver ion technology, that inhibits the growth of a broad range of micro-organisms. BioCote® is incorporated into the plas-
tic parts of the system at the time of manufacture, giving it built-in continuous anti-microbial protection against bacteria,
mold and fungi, making it cleaner and safer.
Culligan Executive Cooler systems come with a 1 gallon (4 liters) cold tank with an 8-watt in-tank UV lamp. Therefore, the
Culligan Executive Cooler systems are protected on the inside by UV and on the outside by BioCote providing the ultimate
in cleanliness for your cooler.
The Culligan Executive Cooler comes with two empty single heads installed inside that will enable you to configure it for
the condition of the incoming water supply. You decide on the filtration needed and then simply twist the filters into the
filter heads behind the lower front panel.
To create the most common two stage filtration system in the tower model, we recommend the following:
• First: 5 micron Carbon Block (Culligan P1020266) to reduce chlorine.
• Second: Total Defense cartridge (Culligan P1020274) for additional fine filtration as well as the reduction of chlo-
rine, chloramines, mercury, lead, cysts, MTBE and VOCs.
Of course, your local water conditions may require alternate selections for the wide range of Aqua-Cleer® cartridges of-
fered by Culligan.
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 damage to 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.

local codes if they differ from the standards used in this manual. To ensure proper and efficient opera-
tion of the Executive Cooler to your full satisfaction, carefully follow the instructions in this manual.

Executive Cooler Overview 3
Cat. No. 01021716
Executive Overview
Cold Tank
The cold tank is manufactured from 304 Stainless Steel which is non-corrosive, inert and reflects Ultraviolet (UV) light.
The cold water temperature is preset at approximately 41°F (5°C) by the factory. The capacity of the cold tank is 1 gallon
(4 liters). The water stored in the cold tank is chilled and exposed to UV at the same time. This inhibits bacterial growth
in the water and on the internal surfaces of the tank. The cold tank temperature is controlled by a thermostat that is set at
the factory.
Hot Tank
The hot water tank has a 0.4 gallon (1.5 liters) capacity. It is manufactured from 304 stainless steel which is non-corrosive
and inert. Heating is provided by an 800 watt heating element. The temperature of the Hot Tank is set at the factory to
185°F (85°C). A BI-metal overload thermostat is fitted to stop the tank overheating and is reset manually.
Room Temperature Water
This only provides filtration of your water. No further cooling, heating or treatment is done to the water in this option. The
temperature of the water will be the same as the room temperature. The room temperature water should be flushed after
long periods of non use, including weekends.
UV Lamp
The UV light is a TUV lamp with a wavelength of 253.7 nm, which is very efficient at controlling bacteria. UV light inacti-
vates bacteria by compromising their DNA. An 8 watt UV lamp is used in the Executive unit. The UV lamp is immersed
in the center of the cold tank. It is protected by a quartz sleeve which allows UV light to pass through to the water. The UV
lamp should be changed every 12 months. The quartz sleeve should be removed and cleaned when the lamp is changed.
PCB
The PCB (Printed Circuit Board) is the control unit for the Executive Cooler. It is responsible for the selection and dispens-
ing of water. The PCB drives an LED which informs the user of the status of the unit. The PCB has a power on indicator
and also indicates to the user what option of water is currently selected by changing color. Cold water will always be the
default option. Hot water must be selected and then the main button pressed in order to dispense hot water.
Compressor
The compressor uses R134a non-ozone depleting refrigerant gas. The compressor is controlled by an electromechanical
thermostat, which controls the temperature of the water in the cold tank unit.
Water Pipe and Fittings
All water connection fittings are approved to NSF standard 61. The machine is connected to the water supply by a 1/4”
female bulkhead fitting. The entire internal water circuit and all components which come in contact with water are food
grade NSF / WRAS approved.
Water Valves
Water dispensing to the customer is achieved by means of a 24V DC electrical solenoid valve. The valves are energized
each time the customer pushes the dispense button for a drink. DC voltage is used for safety.
Plastic Panels
The molded panels are made from recyclable ABS plastic. All the ABS plastic panels are UV resistant and meet the stan-
dards of CE and UL.

Safety Information 5
Cat. No. 01021716
Electrical Safety
• Only connect the power cord to a 120V, 15A (GFI preferred) properly grounded outlet.
• Never pull the power plug from the outlet with a wet hand or allow the plug to get wet.
• Keep the power cord out of heavy traffic areas. To avoid a fire hazard, never put the power cord under rugs, near
radiators, stoves or heaters.
• Do not use a damaged power cord or plug. If the power cord is damaged, a qualified service technician must
replace it.
• Do not use an extension cord with the Executive Cooler.
Installation and Usage Safety
• Keep the Executive Cooler away from direct sunlight and excessive humidity.
• Keep at least 3 inches from the wall.
• Do not lay the Executive Cooler down on its side. If for some reason the unit was placed on its side, it must stand
upright for a minimum of 2 hours before operation to allow the compressor to stabilize.
• Connect the water supply to a cold water line only. Feed water over 105°F (41°C) can damage the filters.
• Never install the system where it could freeze.
• If the feed water pressure is over the recommended operating pressure of 60 psi (4 bar), install a pressure-reduc-
ing valve in the water line. Be aware of pressure transients.
• Filters should be replaced on schedule. Overused filters will deteriorate the performance of the system.
• Drain the water out of the Executive Cooler after long periods of non-use; this will allow a fresh batch of water to fill
the system.
