1. PRECAUTIONS
AND GENERAL
RECOMMENDATIONS
Connect to potable water supply: this system is to be used for water only and is not intended
for use where water is microbiologically unsafe or with water of unknown quality without
adequate disinfection. The system is not intended for treatment of contaminated water.
Tip hazard: the dispenser could tip or fall causing serious injury. Always install the unit
on a firm, flat, and level surface and secure unit to cabinet, wall, or floor if needed. Never
place heavy items on top of the unit and never climb, stand, or hang on the unit or storage
cabinet to prevent injury and damage. Transport the unit empty and always use material
handling equipment or two people with proper lifting technique to reduce injury risk.
Store and transport unit empty: the unit must be completely drained and sealed before
storing to avoid stagnation and reduce microbiological contamination (potential bacterial
growth).
Always sanitise before use: sanitise before use to eliminate any potential microbiological
contaminants.
Installation and maintenance: the installation, maintenance, sanitising and any repair
must be performed by qualified persons trained by Waterlogic or their authorized
distributors only. Do not remove any panels or covers unless qualified and competent to
do so. The detachable hose-sets and the connection kit used to connect the main water
are supplied by the technician. Do not reuse connectors.
Indoor use only: never expose to direct sunlight, heat sources, to freezing temperatures,
ambient air temperature above 32°C (86°F) and keep the unit away from excessive
humidity.
Ensure there is proper ventilation: ensure there is adequate clearance around the unit to
allow refrigeration system condenser to dissipate heat. Warmer environments require more
clearance around the unit. Minimum clearance around all surfaces of the machine is 100 mm.
Caution with cooling fluid: Waterlogic machines use both R134a and R600a (market
dependent) as cooling gas. R600a is a flammable gas, precaution is required. Only
qualified and certified personnel should empty, replace or fill the machines refrigerant
gases. Ensure always the proper management and transportation of the machine to avoid
damaging the refrigerant fluid and causing a dangerous leak.
Use a water pressure regulator: Waterlogic will not be responsible for injury or damage
caused by excessive water pressure. Input or feed pressure must be regulated to 3 bar.
Be aware of any potential pressure surges caused by building/municipal pumping
stations. Water block devices and external leak detectors are strongly recommended.
