• After flow sensor is properly installed, turn on the cold-water supply and double check for
leakage.
NO-FLOW INSTALLATION
If this product is to be used with no-flow appliances such as furnace, boiler, direct vents, wall
heaters, etc. or if this product is intended to be used with gas tankless water heaters without the
need of flow sensing function, you MUST unplug the “Temp.Flow” port as shown below in order for
HUGO to function properly. With this setup, HUGO will provide AC output automatically and
continuously whenever there is a power loss and operate in battery mode; when power restores,
city power will automatically recharge HUGO and pass-thru city power to downstream appliances.
Flow sensor can also be purchased separated from SPS, please visit

for more details.
TEMPERATURE SENSOR SETUP
• Guide the temperature sensor out of HUGO’s right compartment.
• Attach the sensor’s silver plate to a location on the cold-water supply line that is closest to the
tankless water heater and not jacketed, this will ensure maximum protection of the tankless
water heater’s heat exchanger from freezing.
• Use the provided string tie to secure the silver plate to the cold-water piping.
