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.
