Water coolers can harbour bacteria, algae, and moulds that affect the taste and appearance of your water but may also cause illness such as vomiting and diarrhea. Regular cleaning and sanitizing of these units can prevent these problems.
Steps for cleaning and sanitizing:
• If water cooler is refrigerated, unplug cooler unit and remove bottle.
• Empty reservoir by draining any remaining water in dispensing faucet.
• Disassemble cooler unit by removing splashguards, spill trays, water holding reservoir and faucet.
• Clean splashguards, trays and reservoir with soap and water and sanitize using a 100ppm bleach and water solution (one teaspoon (5ml) of household bleach to 4 cups (1L) of water). Allow a contact time of 45 seconds.
• When cleaning faucet area disassemble pipe from tap if possible and clean with soap and water.
Sanitize faucet pieces by soaking in the bleach and water solution. Allow a contact time of 45
seconds. A small tap brush can be used to clean internal parts of the tap and pipe.
• Reassemble unit and flush with clean water prior to use.
• Store water cooler in a cool dry place where possible, to prevent algae growth.
