New 13‐Watt UV lamp Water Pitcher or Container to collect water from the faucet 5‐gallon container or drain basin Sanitizer ‐ Household Bleach (5.25% Sodium Hypochlorite) or Citric Acid Based Cleaner 1. WARNING! HIGH VOLTAGE ELECTRICAL HAZARD. Unplug before inspection and service. 1. Visually inspect all electrical and water connections for signs of wear or damage. 2. Waterlogic recommends changing the UV Lamp every 12 months. WARNING! ULTRAVIOLET RADIATION. Protect your skin and eyes against ultraviolet rays. Never look directly at an operating UV light. Disconnect before removing UV Lamp. CAUTION! UV LAMPS ARE HAZARDOUS. Lamps are considered Hazardous Waste and must be disposed of accordingly. Refer to Product MSDS sheet for details. CAUTION! UV SYSTEM IS FRAGILE. Never handle the UV Lamp or Quartz Sleeve 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. 3. Ensure there is adequate (minimum of 2”) clearance around the Cube Water Treatment System and clean the condenser grill and compressor fan to provide efficient cooling system operation. 4. Sanitize the cold tank per instructions in the pre‐installation procedures. Clean and sanitize external surfaces of the Cube Water Treatment System. Use soap and water or chemicals that are compatible with ABS plastic and will not damage or degrade the product surfaces. Remove and clean the faucet. Replace as needed. WARNING! SANITIZER MAY CONTAIN HAZARDOUS CHEMICALS. Use of proper personal protective equipment such as rubber gloves and eye protection is required. CUBE Manual Page 15 – Revision 10‐8‐2018 ...

The chambers are separated by a welded‐in tank baffle. Water always flows into the bottom of the tank and out the top to the faucet. The Hot Tank outlet tube has a restrictor in its base. This ensures the reservoir is always full by allowing more water in than out. There is a small hole in the side of the tank outlet tube that allows air and water to pass into the vent chamber as it is heated. Water in the vent chamber is suctioned back through the outlet tube vent hole when water is dispensed. Expansion of water as it is heated in the reservoir will push the water out the faucet when the outlet tube vent hole becomes plugged with debris or scale. The small Outlet Vent Hole is susceptible to scale build up and is a key indicator that descaling is required. It is critical to descale the Hot Tank through the vent line and outlet line on a regular basis to prevent this problem. Descaling through the inlet and/or outlet lines only will not clean the vent chamber and outlet vent hole properly. CUBE Manual Page 16 – Revision 10‐8‐2018 ...

FILTER REPLACEMENT Filters should be configured to optimize your system. Filters need to be configured and specified to do the job given the local water conditions, usage, maintenance schedule, and placement restrictions. In order for our filters to perform as represented and to provide the best quality water possible, it is essential that filters be replaced periodically. The frequency of filter changes depends on your water quality and your water usage. For example, if there is a lot of sediment and/or particles in your water, then you will have to change your filters more frequently than a location with little to no sediment. Be sure to replace your filters whenever you notice a decline in the performance, whether it is a drop‐in flow rate and/or pressure or an unusual taste in the water. WARNING! Read and understand the contents of this manual before attempting to service CUBE. Failure to follow the instructions in this manual could result in death, serious personal injury, or severe property damage.
