oPeRAtIoN MANUAL

Congratulations for choosing a PURA point-of-use water bottle-free cooler system. The PURA Max or

Max Plus dispenses both hot and cold water using either modern multi-filter or optional reverse osmosis technology. PURA Max Plus models with a recirculating UV system limit bacterial growth and bio-film within the cold tank system.

The PURA Max Plus puts an end to bottled water deliveries by filtering your customer’s own water supply of contaminants and bacteria, resulting in a virtually endless supply of crystal clear, filtered water.

The PURA Max Plus has been designed to facilitate the use of either the 1240 Series Reverse Osmosis

System or the Pentek Filter Quick Change Cartridge System.

Note: In this operation manual, all references to PURA Max or Max Plus are denoted by the words “Max or

Max Plus.”

Note: The Max or Max Plus are not intended for use with water that is microbiologically unsafe or of unknown quality without adequate disinfection either before or after the system.

Note: Check with your public works department for applicable local plumbing and sanitation codes. Follow local codes if they differ from the standards used in this manual. To ensure proper and efficient operation of the Max Plus to your full satisfaction, carefully follow the instructions in this manual.

Introduction of Recirculating UV system

The Max or Max Plus can be ordered with a factory-installed recirculating ultraviolet (UV) loop system. The system is inexpensively designed to provide years of passive bio-film control of the cold tank system.

The recirculating UV system consists of a small 110V fountain pump, and a four watt germicidal ultraviolet lamp that is contained within a specially-designed stainless steel housing.

The pump is mounted directly underneath the cold tank, and takes suction from the bottom of the cold tank.

The UV lamp assembly is mounted vertically next to the cold tank. The pump takes water from the base of the cold tank and circulates it through the UV assembly, returning the water back into the top of the cold tank.

The UV lamp housing is designed with a very thin gap from the quartz sleeve to the highly-reflective SS wall of the housing in which the water flows through. This design ensures maximum UV dose and penetration through the water stream as it flows past the UV lamp.

The system is designed to cycle the full cold tank past the UV lamp as much as 60 times per hour, or once per minute. The system has proven to be highly effective at controlling the bio-film growth in the cold tank, thereby minimizing the need for routine cold-tank sanitization.

IMPoRtANt NotIces ABoUt tHe UV sYsteM

1. ALWAYs fill the Max or Max Plus with water before plugging the machine into power.

Note: The recirculating UV system powers up immediately when the Max or Max Plus is plugged into a power outlet, regardless of the position of the hot and cold switches on the rear of the machine, if the UV power switch is on. Filling the hot and cold tanks prior to powering the machine will enhance the life of the recirculating pump.

2. Prime the recirculating pump for proper operation.

Once you fill the hot and cold tanks, and have powered the Max or Max Plus, remove the top cover of the machine and make sure water is recirculating through the UV system. In a small percentage of cases, the recirculating pump will require priming. To prime the pump, simply unplug the power cord of the Max or Max Plus from the power outlet, and immediately observe the stream of air bubbles that will rise up from the base of the cold tank. Reapply power and the Max or Max Plus recirculating system will function normally.

3. Replace the UV lamp and filtration/Ro components in the Max or Max Plus on an annual basis.

The lamp is nominally rated at 9,000 hours, or 375 days. This is a nominal rating, which means you can typically expect a full 1 year of life from the lamp. However, voltage fluctuations to the

Max or Max Plus

caused by lightning storms or industrial sources can terminate lamp life prematurely. When the lamp fails, an alarm built into the ballast will annunciate an audible beep. The alert can be reset by replacing the UV lamp. Note that the UV output of the lamp fades with time, and after 1 year, the lamp needs to be replaced to optimally provide bio-film and bacteria control in the product water. Although you may still see a faint blue glow from the lamp after one year of use, be aware that the UV portion of the light spectrum is no longer present and the UV lamp is no longer providing bacterial control.

The lid, which simply snaps into place, will help minimize mold and mildew buildup inside the cold tank by providing a “sealed” environment. Please note the arrow (with sticker on side of foam insulation) for proper installation. To ensure the level float operates correctly, please align the tab on the new plastic lid with this arrow. Refer to the pictures shown below. This change does not impact the way you setup and operate the machine. Also changed on the unit is the addition of a small GAC filter designed to be placed on the inlet return of the recirculating UV loop inside the cold tank. This filter comes packaged with the machine inside the plastic bag contained in the drip tray. This filter is designed to continually filter impurities in the water, and to eliminate the need for rinsing the machine upon initial installation. The small end of the filter connects into the return port from the UV loop inside the cold tank. This filter does not require replacement on regular intervals. Prior to using the machine, the filter needs to be rinsed and flushed (to a drain, not through the machine) with a gallon of water to remove carbon fines.

If you are experiencing any operational or technical problems with the cooler machines and cannot troubleshoot the problem yourself, please contact 1-800-288-1891 for technical support and please do not return the cooler to the dealer unless you have received the RGA (Return Goods Authorization)

Number by the technical support personnel.

1. No hot water? Check power to the compressor. Check wiring, lights, breaker.

2. No cold water? Rotate the cold tank thermostat fully clockwise. Wait 3 minutes, is the compressor running?

If the compressor is not running, then check the thermostat.

3. Check the thermostat by taking an ohms reading across the electrical connectors on the thermostat. They should read 0 ohms. If they read infinity, the thermostat is faulty. Replace the thermostat.

4. If the thermostat checks OK, but the compressor is not running either the starter or overload on the side of the compressor have failed or have become loose. Check connections.

5. If the compressor is running and is very hot to the touch the refrigerant may have leaked out.

6. If the compressor is cool to the touch, then the compressor has failed. Replace compressor.

Things to check are power (by seeing if there’s hot water), cold thermostat (when it is fully turned clockwise), compressor starter and overload relays, and gas leak. If you surmise a gas leak, you should find oil on one of the welded copper lines leading to and from the compressor.
