General Information
• The BU1PVECHS Series coolers are designed for use with a supply of bottled water. The cooler
should not be used with water supplies of unknown bacterial quality or those that are not already
fit for human consumption.
• This unit is suitable for indoor use in domestic, commercial & industrial locations. They should
not be sited in locations where they may be subjected to rain or snow.
Cooling System
• The BU1PVECHS Series coolers use the OASIS Pressure Vessel Direct Chill (PVDC) cooling
tank system. The cooling tank is manufactured from 304 Stainless Steel which is non-corrosive
and inert.
• The cold water temperature is preset at the factory at approximately 7°C (45°F) – the water
temperature is controlled by a thermostat that is located on the back of the unit. Cold water
temperatures may be adjusted via a slotted screw on the body of the control (can be accessed
through wires on the condenser). Turning this screw in the clockwise direction will make the
water colder (and vice versa).
Hot Water System
• The hot water temperature is preset at the factory at approximately 86°C (187°F) – the water
temperature is controlled by a thermostat that is located on the hot tank. Hot water temperatures
may be adjusted depending on the hot tank model.

Carbonated Water Circuit
• The carbonation level of the water is based on coldness of the water and pressure of the CO2
bottle. The carbonation level in the water can be increased by either raising the CO2 pressure
(max 60psi/15 l per min) or reducing the temperature of the cold water used for carbonation.
• The pre carbonated cooled water is taken from the cold tank, pressurised through a pump and
mixed with CO2 gas within a carbonator tank inside the OASIS Pressure Vessel Direct Chill
(PVDC) cooling tank system. The tank is made from food grade plastics and 304 Stainless Steel
• Carbonated water temperatures are controlled by the temperature of the cold water inside the
OASIS Pressure Vessel Direct Chill (PVDC) cooling tank system. Adjusting the cold water
temperature also adjusts the carbonated water temperatures.
• The carbonator tank is a pressurised system and protected with expansion tank.
• Purging of the CO2 circuit is necessary at initial start up, after sanitization and after the water is
completely drained in the reservoir.
Compressor
• The compressor uses the hydrofluorocarbon refrigerant R134a which is a non-Ozone depleting
substance with a Global Warming Potential of 1,300. The compressor is controlled by an
electromechanical thermostat that controls the temperature of the water in the cold tank
• The compressor is equipped with an automatic reset protector that disconnects the motor from
the line in case of an overload.
• This unit is equipped with a sealed compressor that requires no additional lubrication.
Water Pipe and Fittings
• The entire internal water circuit and all the components which come in contact with water are
made from food grade approved material
Mounting Feet
• The unit is supplied with 4 mounting feet which can be used to level the cooler on uneven
surfaces.
Maintenance
• Periodically remove dirt and lint from the condenser. Inspection should be done every three
months. If cleaning is required, disconnect the power supply cord, and then clean the condenser
with a small stiff non-wire brush. Following this procedure will ensure adequate air circulation
through the condenser for efficient and economical operation.
NOTE: Under no circumstances should the cabinetry be cleaned using a water jet
• WaterGuard helps prevent foreign matter from entering the cooling tank. Its parts should be
inspected, cleaned and replaced (if necessary) at regular intervals. Operation of the cooler
without WaterGuard components in place may allow airborne dust particles to enter the cooling
tank.
• Cleaning of water contact components
o The European Bottled Water Association recommends that water contact parts should be
cleaned and sanitised every 3 months. It is recommended that this process is carried out
by trained personnel
Water Valves:
• Control of water dispensing is achieved by means of electrical solenoid valves (3x 24V).
