PART 2 – PREPARE THE STORAGE TANK UNCRATING STORAGE TANK – Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee. o COLD WEATHER HANDLING – If the storage tank has been stored in a very cold location (BELOW 0 F) before installation, handle with care until the plastic components come to room temperature. Remove all sides of the shipping crate to allow the storage tank to be moved into its installation location. A.
B. LOCATING THE STORAGE TANK This storage tank is certified for indoor use only. DO NOT INSTALL OUTDOORS. Outdoor installations ARE NOT covered by warranty. Choose a location for the storage tank as centralized to the piping system as possible. Also, locate the storage tank and domestic water piping where it will not be exposed to freezing temperatures. All piping should be insulated. Additionally, place the storage tank so that the drain, controls, and inlets/outlets are easily accessible.
Water that is classified as hard and very hard must be softened. CLASSIFICATION Soft Slightly Hard Moderately Hard Hard Very Hard MG/L OR PPM 0 – 17.1 17.1 – 60 60 – 120 120 – 180 180 and over GRAINS/GAL 0-1 1 – 3.5 3.5 – 7.0 7.0 – 10.5 10.5 and over If the hardness of the water exceeds the maximum level of 7 grains per gallon, water should be softened to a hardness level no lower than 5 grains per gallon.
B. TANKLESS COIL CONNECTIONS Use a ¾” nominal minimum pipe size. On the tank, tankless inlet is to be connected to a bronze or stainless steel circulator with the arrow pointing away from the tank and toward the tankless coil. This pipe will also have a tee for the cold supply to the tankless coil. (An optional check valve may be installed between the cold supply line and circulator to prevent short circulating the tankless coil.
Do not thread a cap or plug into the relief valve under any circumstances! Explosion and property damage, serious injury, or death may result. D. TYPICAL INSTALLATION Figure 3 – Typical Storage Tank Installation – NOTE: Check Valves are Optional - Circulators May Have Internal Flow Checks (IFCs) NOTE: If a backflow preventer or no return valve is installed, a thermal expansion tank is required on the cold water inlet between the storage tank and backflow preventer. LP-32 Rev. 3.25.
E. POTABLE EXPANSION TANK A thermal expansion tank is required in the system designed for potable water use, to offset the expansion of stored water as the temperature is elevated. PART 4 – CONTROL AND WIRING A. CONTROL A pre-wired surface mount control is provided on your storage tank. Temperature may be set by removing lower cover screw and lower cover. VERY IMPORTANT: SEE SCALDING NOTE ON PAGE 10. B. WIRING All wiring is to be done in accordance with all applicable local and state codes.
A water heating system can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain appliances, such as dishwashers and automatic clothes washers, may require increased water temperature. By setting the thermostat to obtain the increased water temperature required by these appliances, you may create the potential for scald injury. To protect against injury, you should install a mixing valve in the water system.
TROUBLESHOOTING NO HOT WATER PROBLEM Zone valve not opening Circulator not operating Tank control set too low Boiler control set too low Wiring incorrect Tank control failure Zone valve failure Circulator failure Air trap in loop POSSIBLE SOLUTION Open manually to replace.
