OVERVIEW
PURA Ultimate
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 adjustable 35-54°F (2-12°C). 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.
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 180°F (82°C). A BI-metal overload thermostat is fitted to stop the tank overheating. It 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.
Internal Storage Reservoir
An internal storage reservoir eliminates the need for an external storage tank. The entire water treatment system is
contained inside the cabinet. A double float mechanism guards against overflows.
Built-in Leak detection and Shutoff
A plastic containment tray in the base of the unit contains a leak detector. If a leak should occur, the detector will
immediately shutoff the inlet solenoid valve.
UV Lamp
The UV light is a TUV lamp with a wavelength of 253.7 nm, which is very efficient at controlling bacteria found in water.
UV light inactivates bacteria by impacting DNA. An 8 watt UV lamp is used in the PURA Ultimate. 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.
compressor
The compressor uses R134a non-ozone depleting refrigerant gas. The compressor is controlled by an electromechanical
thermostat monitoring 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 unit 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 certified.
Water dispensing
Water dispensing to the customer is achieved by means of mechanical switches. No electricity is used in the buttons
pushed by the customer.
Plastic Panels
The molded panels are made from recyclable ABS plastic. All the ABS plastic panels are UV resistant and meet the
standards of CE and UL.
