Installation Instructions 13 Selecting a Location for the ETS Assembly Select an appropriate location to install the ETS assembly. The location must meet the following minimum requirements: • The ETS assembly is not intended for outdoor installation. • Keep the distance between the ETS assembly and the water heating source to a minimum. This reduces piping heat loss and provides minimal friction loss. • The ETS assembly location should be where leakage from the piping field connections will not cause damage to the surrounding area. • Consider the location of new or existing piping and electrical. Recommended Clearances To ensure serviceability of the ETS assembly, the following minimum clearances must be met: • Left and Right Sides: 18 inches • Top: 24 inches • Front: 24 inches • Rear: 0 inches General Electrical Guidelines All assemblies require a 120Vac line voltage dedicated circuit with a 12 Amp circuit breaker. 059326‐00 Rev D Heat‐Timer Corp.
14 ETS Installation and Operation Manual General Piping Guidelines • All piping must meet or exceed all applicable local, state, and/or federal guidelines, codes, regulations, and laws. • Support all piping using hangers. DO NOT support piping by the unit or its components. • Use isolation valves (provided) to isolate the ETS assembly. • Use unions (provided) to allow for servicing and, if required, removal of the valve and other components. • Include drain valves (provided) to assist in servicing of the ETS assembly. • Use a generous amount of pipe thread sealant. DO NOT use pipe thread tape. When using the valve in a domestic water application, ensure the thread sealant is compliant with domestic water application and meets NSF 61 requirements.

Installation Instructions 15 Recirculation Pump Sizing For proper operation of the ETS, the assembly must be installed in a system with constant recirculation. The ETS provides a dedicated recirculation connection. For optimum valve function, it is recommended that the building recirculation temperature is at least 7°F lower than the desired setpoint temperature. In addition, it is recommended that the HOT water supplied to the ETV valve is at least 20°F above the desired setpoint. The recirculation pump (not provided) must be properly sized for the following recirculation rates: Table 3: ETS Recommended Recirculation Flow Rates Recirculation Model Flow Rate ETS‐15 10 gpm ETS‐20 15 gpm ETS‐25 15 gpm ETS‐30 30 gpm ETS‐40 30 gpm In systems without a building recirculation line, it is recommended that a flow switch (not provided) is installed. WARNING HEALTH RISK! Any domestic hot water system that does not utilize a constant building recirculation line poses a potential risk of stagnant water in the system. Stagnant water provides ideal conditions for the growth of bacteria, such as Legionella. The flow switch should be located on the MIXED outlet field piping above the ETS assembly. Activation of the flow switch should be at the lowest potential draw of the system. Refer to “Wiring the Flow Prove” on page 42 for wiring to the ETV Platinum Plus module for a flow switch (Prove). Refer to “Flow Switch” on page 28 for proper STARTUP menu settings for installations using a flow switch. 059326‐00 Rev D Heat‐Timer Corp.
