Service Requirements - WaterLogic WL3FW FIREWALL Manual

WARNING! Read and understand the contents of this manual before attempting to service
WL3FW. Failure to follow the instructions in this manual could result in death, serious personal
injury, or severe property damage. Only trained and qualified technicians should attempt to
install, maintain, or service Waterlogic Equipment.
1. Visually inspect all electrical and water connections for signs of wear or damage.
DANGER! HIGH VOLTAGE ELECTRICAL HAZARD. Always unplug before inspection and service.
2. Waterlogic recommends changing the UV Lamp (CT-2090) every 6months under normal single
shift usage. The lamp may require more frequent changes if placed in high volume/multi-shift
environment. Contact Waterlogic for specific recommendations.
WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet rays.
Never look directly at an operating UV light in the faucet. Disconnect before removing UV Lamp.
3. Clean the quartz spiral that surrounds the UV lamp with a non-abrasive cloth, descaling solution,
or ultrasonic bath if needed when changing UV lamps. Inspect the Firewall housing for wear or
damage and replace as necessary.
CAUTION! UV SYSTEM IS FRAGILE. Never handle the UV lamp or Quartz Spiral with bare hands.
UV Lamp and quartz sleeve must be free of oils and contaminants to ensure proper operation. Use a
soft non-abrasive cloth to clean.
4. Test Firewall UV system by unplugging the lamp. 20 second audible alarm and Firewall light
should go out. Cold and Ambient/Sparkling icons should be disabled.
5. The filters should be replaced every 6 months or if the GAC filter exceeds a capacity of 7570
Litres and the CBC filter exceeds a capacity of 9464 Litres, whichever comes first. Flush filters per
manufacturer's recommendations to rinse carbon fines. Do not rinse the filters through the unit
solenoid valve(s) and tanks to avoid contamination.
6. Ensure there is adequate 50mm (2") clearance around the unit and clean the condenser grill and
compressor fan to provide efficient cooling system operation.
7. Clean and sanitize the drip tray and drip tray grille. Replace if needed.
8. Sanitize the cold, ambient or sparkling circuits annually per instructions in the Pre-delivery
procedures.
9. Clean and sanitize external surfaces of the unit. Use Aquadosa or a Sanitizer that is compatible
with ABS plastic and will not damage or degrade the product surfaces.
