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. Please note that the Cube
should not be exposed to direct sunlight. Placing the Cube in direct sunlight from a
window, close to a radiator, or in a room of high ambient temperature, will affect the
efficiency of the refrigeration circuit.
UV LAMP
The UV light is a 13 Watt germicidal lamp at a wavelength of 253.7 NM, which is
very efficient at destroying bacteria in water. The UV lamp is situated in the Firewall
Chamber surrounded by a quartz spiral that attains NSF standard 55 purification
of water. The UV lamp must be replaced at 12 months intervals or when indicated
by the warning lights, and the quartz spiral cleaned by using an ultrasonic bath if
needed.
PCB
The PCB (Printed Circuit Board) is the control unit for the Cube; it is responsible
for the functions of all the mechanical and electrical parts (24V DC) including the
solenoid valves, touch panel and LED’s.
COMPRESSOR
The compressor operates at 220-240V at 50Hz or 120V at 60Hz. It uses 55 grams/
1.94 Oz of R134a non-Ozone depleting refrigerant gas.
WATER PIPES AND FITTINGS
The inlet and the internal water circuit pipe size are 1/4” and 5/16”. The entire internal
water circuit and all the components which come in contact with water are food
grade NSF approved. The cold and ambient water tubing inside the machine should
not be exposed to water above 25˚C.
WATER VALVES
Dispensing of water to the customer is achieved by means of a 24V DC electrical
solenoid valve. The valves are energized every time the customer touches the
dispense button for a drink. DC voltage is used to give a positive and quieter action
of the solenoid valve.
