WATER PIPE AND FITTINGS

All water connection fittings are made by the John Guest Company and are approved 

to NSF standard 51. The machine is connected the water supply by a ¼” female 

bulkhead fitting.

The entire internal water circuit and all the components which come in contact with 

water are food grade NSF / WRAS approved. 

PLASTIC PANELS

The moulded panels are made from ABS plastic. All the ABS plastic panels are UV 

resistant and incorporate the heat retardant standards of CE and UL... Please note 

that  the  machine  should  not  be  exposed  to  direct  sunlight.  Placing  machines  in 

direct sunlight from a window, or close to a radiator, or on in a room of high ambient 

temperature will effect the efficiency of the refrigeration circuit.

WATER PUMP

The pump is 24V DC and forces the pre-chilled cold still water in to carbonation tank 

at  high  pressure.  This  pressure  is  required  to  overcome  the  internal  carbonation 

tank pressure of 45 PSI of CO

2

 gas. By forcing cold water at pressure into a tank of 

CO

2

 gas the machine produces carbonated water. A level probe in the carbonation 

tank controls the water pump connected to the machine PCB.

THE GAS REGULATOR

The correct flow and pressure of gas that is fed to the carbonation tank is controlled 

by a CO

2

 gas regulator and is factory set at 45PSI. The gas pressure can be increased 

and this may see an increase in the level of carbonation, but this is also relevant 

to water temperature and pressure. Over adjustment of gas pressure (50PSI) will 

see no increase of carbonation levels and in fact will stop the machine functioning 

correctly. Food grade CO

2

 gas must be used at all times.

FILTERS

The  filtration  system  on  the  WL850HV  is  NSF  approved  two  –stage  filter.  Stage 

one is a 10 micron screen; Stage two is a Granular Activated Carbon (GAC) process 

which will remove a whole range of contaminates e.g. chlorine, pesticides, sediment, 

and any taste or odour that may be in the water. Carbon filter also remove a whole 

range of other contaminants found in water. It is important for the UV sterilization 

system to be supplied with clean water in order to achieve maximum efficiency. If the 

water is not cleaned of particulate matter, this will restrict the penetration of the UV 

radiation into water. There are many kinds of different filter combinations available 

from Waterlogic to suit local water conditions, and for the exclusion of Crypto, Cysts 

and heavy metals. All filters must be changed at 6-month service interval.

HOT TANK 

The hot water tank has a two litre capacity; it is manufactured from 304 stainless 

steel and is heated by a 800 watt heating element. Temperature of the Hot Tank 

is controlled by a mechanical thermostat and is factory set at 87ºC, this being the 

ideal temperature for instant drinks. A thermal cut out is fitted to the Hot Tank to 

prevent overheating. The tank can be fitted with an optional scale-inhibiting filter 

to increase the tank life. Setting the hot water temperature at 87 ºC also helps stop 

scale forming in the Hot Tank.

COMPRESSOR

The  compressor  operates  at  220-240V  and  at  50Hz.  It  uses  R134a  non-Ozone 

depleting refrigerant gas. There is also the option to use Natural refrigeration gas

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 a customer pushes the dispense 

button for a drink. DC voltage is used to give a positive and quieter action of the 

solenoid valve. The WL850HV model is fitted with both inlet and outlet valves.
