Introduction 1
Cat. No. 01023621
Introduction
Thank you for purchasing the Culligan All Purpose Cooler. The Culligan All Purpose Cooler brings a unique, fresh ap-
proach 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 virtu-
ally unlimited.
The Culligan All Purpose Cooler is enhanced with a unique anti-microbial agent, based on silver ion technology, that
inhibits the growth of a broad range of micro-organisms. This Agent is incorporated into the plastic 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. The Culligan All Purpose 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.
Culligan All Purpose Cooler systems come with a 1 gallon (4 liters) cold tank.
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: 5 micron Carbon Block (Culligan P1020266) to reduce chlorine.
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.

All Purpose Cooler Overview 3
Cat. No. 01023621
All Purpose Overview
Cold Tank
The cold tank is manufactured from 304 Stainless Steel which is non-corrosive. 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 cold tank temperature is
controlled by a thermostat that is set at the factory.
PCB
The PCB (Printed Circuit Board) is the control unit for the All Purpose Cooler. It is responsible for the selection and
dispensing 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.
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. 01023621
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 All Purpose Cooler.
Installation and Usage Safety
• Keep the All Purpose Cooler away from direct sunlight and excessive humidity.
• Keep at least 3 inches from the wall.
• Do not lay the All Purpose 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 All Purpose Cooler after long periods of non-use; this will allow a fresh batch of water to
fill the system.
