Machine Overview WATERLOGIC 4 FIREWALL STANDARD COLD TANK (2 Litres) The Waterlogic 4 Firewall is available in the following options: a) Cold, Hot & Sparkling (Full Option) b) Cold & Hot c) Cold & Ambient d) Cold & Sparkling e) Cold Only f) Cold Sparkling & Ambient HOT TANK The standard cold tank is manufactured from 304 StainlessSteel which is noncorrosive. The temperature of the Cold Tank is controlled by a microprocessor and can be set between 3°C and 12°C.
IN faucet UV WATER VALVES UV LAMP PLASTIC PANELS PCB PARTS REQUIRED FOR SPARKLING WATER The Unique design allows the faucet area to be steralised before, during and after every dispense. There are two types of sensors available, the CDS UV sensor that detects if the UV lamp is working and the UV sensor that monitors the UVC intensity from the UV lamp. The UV light is an 11Watt germicidal lamp at a wavelength of 253.7 NM, which is very efficient at destroying bacteria in water.

Carbonation tank Pre Delivery Inspection Procedures (PDI) CAUTIONS: Only competent trained technicians should work on Waterlogic products. Waterlogic units may weigh over 25KG. We recommend caution when lifting. Packing materials could present a trip hazard. Keep them off the floor. Take care not to allow the power lead to get wet. If the lead gets wet it must not be used. CO2 gas used for sparkling units is under high pressure. Follow cylinder safety instructions.
1. Remove packing straps and unpack unit and visually inspect for any damage. (Report any defects to Waterlogic as soon as possible). 2. Place the unit on a suitable work bench. 3. Open the top cover by removing the screws and releasing the 2 clips in the dispense area then slide the lid forward and lift up. Use the top support bar to hold top open. 4. Visually inspect all electrical connections and power lead. 5. Visually inspect all water connections. 6.
lifting the WL4 Firewall pressure release valve (yellow), located beside the UV lamp assembly, for approximately 2 seconds. 7. Connect the water supply. All water sources should be potable. Allow the water supply to run clear of any sediment before connecting to the WL4 Firewall. The minimum pressure for the WL4 Firewall to function correctly is 38 PSI (2.6 bar). The ideal pressure is 45 PSI. The maximum pressure 60 PSI. 8.
INSTALLATION KIT 1-20 metres of 6mm 5/16 inch water pipe, PRV (pressure reducing valve) set at 3 bar or 42 psi, Non return valve, Self-cutting saddle valve or isolating valves, Moulded plug fitted, CO2Gas (if required), CO2 Regulator, Customer Handbook Allow 1 Hour • The WL4 Firewall must be installed according to the local guidelines. • Waterlogic strongly recommend that a pressure reducing valve is set at 3 bar and a non-return valve be used on all WL4 Firewall installwations.
Operating Instructions Maintenance and Servicing COLD WATER 6 MONTH SERVICE PROCEDURE Press the cold water button. Cold water will be dispensed immediately. This procedure should only be carried out by persons trained by Waterlogic International or their approved distributors. AMBIENT WATER Press the ambient water button and water will be dispensed. SPARKLING WATER Press the sparkling water button. Sparkling water will be dispensed immediately.
and fill the cold tank with a mix of water and sanitisation fluid. 7. Replace the UV lamp and reconnect the UV loom. Do not touch the UV lamp with your bare hands as this will shorten the lamp life. 8. Machines with the Hot Option. Remove and inspect the faucet. If the faucet is cracked or has excessive build of calcium that cannot be easily cleaned then replace the faucet. Please ensure that you wear cleaning gloves when handling the faucet. 9.
Malfunction Icons Advisory Icons No water supply Check the water supply is turned on, if fault persists please call your authorised service agent A FAULT HAS BEEN DETECTED Please call your authorised service agent The UV lamp has failed Please call your authorised service agent A LEAK HAS BEEN DETECTED Please turn off the water supply and call your authorised service agent FILTER NEEDS REPLACING Please call your authorised service agent THE DRIP TRAY IS FULL Please empty the drip tray Note - If all
the tank to defrost, and then flush the cold water system. Check the temperature settings are correct. If the cold tank is not frozen then check the solenoid valve is operating correctly and being turned on and off when you push the cold button. 5. There is cold water flow but hot water is not flowing: This may be due to calcium build up in the hot tank or the hot water outlet. De-scale the hot tank.
