ELECTRICAL SAFETY PRACTICES
GROUNDING:
In the event of a malfunction or breakdown, grounding provides a path of least resistance
for electric current which reduces the risk of electrical shock.
Improper connection of the equipment grounding conductor can result in a risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor.
Check with a qualified electrician, or service personnel if the grounding instructions are not
completely understood; or if in doubt as to whether the UPS is properly grounded.
Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
DO NOT remove the ground connection from the UPS’s power plug.
WARNING
Use personal protective equipment. Safety glasses must be worn at all times by
all persons installing the UPS.
Have your UPS serviced by a qualified repair person using only identical
replacement part.

WORKING PRINCIPLE
When the utility power is normal, the UPS will transfer the utility power to downstream application.
During a power outage or when the utility power is below 92v or above 138v, the UPS will transfer to
inverter mode.
While in inverter mode, the UPS will monitor flow and temperature sensor (if purchased). When flow
sensor detects a demand for water, it will turn on power output to downstream application. When the
temperature senses 37deg f (+/- 2 deg f) or below, it will also override the UPS to turn on AC output. If
flow sensor does not detect a flow or if temperature is above 37 deg f, the UPS will be in standby mode.
For non-flow applications, unplug (temp.flow) port in front of inverter to allow flow sensing bypass. For
this operation, whenever utility power is lost, the UPS will provide continuous power to downstream
application immediately.

At any time, the UPS detects overload or under/over voltage as indicated by the LED display or
chirping alarm, it will attempt delay restarts. Once such issue is resolved, i.e., battery charge is
normal or load is under 350w, the UPS will automatically restart and remove any fault
indicators.
FLOW SENSOR INSTALLATION
•NOTE: Before installing the flow sensor, make sure water is shut off at the cold-
water supply side.
•Once water pipe is disconnected, some water will drip out of the pipe. Place a bucket or
towel directly under the disconnect point of the water pipe to catch any dripping.
•Flow sensor should be installed in the cold-water piping with the arrow pointing in the same
direction as the cold-water flow (towards the tankless water heater) and in the horizontal
(preferred position) with the 4 screw heads of the sensor on top pointing upward. The flow
sensor can also be mounted vertically. However, in this orientation, when water flow is less
than 0.5gpm, the flow sensor may not be able to open the mechanical flap inside to activate.
•The included flow sensor will require two (2), not provided, ¾” Female BSP “G” Thread
Adapters to transition from G Thread to desired piping (PEX, CPVC, Copper, NPT Etc.)
oEnsure Female Hose Thread Adaptors utilize proper sealing gaskets (washers).
oMake sure to never over-tighten the adapters to the flow sensor. It is also critical to
align the threads correctly to avoid stripping of the threads on the flow sensor.
oIf flow sensor is installed outdoors, please make sure it is properly jacketed to protect
from direct sunlight and freezing conditions.
•Once Flow Sensor is installed and tested for leaks, connect the flow sensor Molex plug securely
into flow signal interface located in the wiring compartment on the right side of the unit.

HUGO USER MANUAL
REV 1.3
SAFEGUARD POWER SOLUTIONS
855.484.6797
PAGE | 12
•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
www.safeguardpowersolutions.com 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.

PAGE | 14
i) Make sure not to tangle the wires inside the HUGO unit for easier maintenance and service calls
in the future.
j) Connect your appliance’s wire cords G (green), N (white), and L (red or black) to the
corresponding positions on HUGO’s “AC Output” of the green MOLEX plug.
•G to PE
•N to N
•L to L
k) Ensure no bare wires are exposed to the outside.
l) Tighten the flat head screws on the green connector.
m) Pull the newly installed wires to ensure a tight connection.
n) Plug the green connector back to the inverter.
OPERATIONS
•When city power is normal, HUGO will bypass power to downstream application while monitors
for input voltage. At this time, the “line” LED light on the front panel should be steady green.
When input voltage reaches beyond the safety zone as set under “input voltage” on section 13
below, HUGO will automatically switchover to battery mode to protect downstream appliances.
At this time, the “INV” LED light will be steady green.
•Once a power outage is detected, HUGO will first chirp once to alert user HUGO is in inverter
mode. The chirp will continue once every 30 seconds and will auto shutoff after 5 minutes.
During this mode, there are two operation sequences:
oThe “INV” LED light is blinking green indicating HUGO is in Standby mode and there is
no AC power output from HUGO. This will occur if the flow sensor is installed and the
“temp.flow” port is plugged in and there is no flow detected in the water line.
oThe “INV” LED light is steady green indicating HUGO is in operation mode and is
providing AC power to downstream application. This happens when:
a. “temp.flow” port is NOT plugged in for no-flow installation;
b. “temp.flow” port is plugged in and the installed flow sensor has detected a
flow in the water supply line.
•When HUGO is operating with the flow sensor, there is a delay shutoff feature that works as
followed:
oDuring inverter mode, at any time the flow sensor senses a signal, HUGO will turn on AC

HUGO USER MANUAL
REV 1.3
SAFEGUARD POWER SOLUTIONS
855.484.6797
PAGE | 15
output continuously for 5 minutes.
oAfter 5 minutes, if no flow is detected, HUGO will turn off AC output.
This feature will prevent frequent restart cycle of tankless water heaters and will allow
users to freely turn the faucet on/off in between water usage.
Note: when tankless water heater is restarting, some models may experience minimized or
stopped water flow, this is due to servo valve inside the tankless water heater is closed.
Once tankless water heater completes its restart cycle, full flow will resume. If at any time
the water flow has stopped and does not return to full flow within 30 seconds, unplug the
temp.flow port to force HUGO to provide power to the tankless water heater. Once the
tankless water heater restarted completely, push in the “temp.flow” port again to resume
water sensing operation.
•When the supply 12v sealed lead acid battery is not fully charged, the third LED light (batt. Lim)
will continue to blink amber. When city power restores and HUGO is charging the battery, this
light will be a steady amber. Once battery is fully charge, this light will be off.
When the supplied battery drops below 20% of its full capacity, HUGO will sound the
audio alert by 2 chirps and 1 pause, after 2 seconds the audio alert will be off. At the
same time, the “batt.lim” LED light will blink twice then pause and continue to blink this
sequence until HUGO is connected to a power source or when city power restores.
•The fourth LED light “Fault” will be steady red when the following occurs:
oThe battery is no longer holding a charge, a replacement is needed. Refer to “Protection
– Battery Under Voltage Protection” in section 13 below.
oThe downstream appliance connected to HUGO has reach above 350W, remove the load
and HUGO will auto reset. Refer to “Protection – Overload or Short Circuit Protection” in
section 13 below.
•When city power is restored after a power outage, HUGO will start charging itself and reset to
utility power mode after 10 minutes. This time delay will allow power grid to become steady to
avoid possible spikes that may harm appliances.
STORAGE AND TRANSPORTATION
Retain the packing box and packing materials. The UPS is a sensitive piece of power equipment.
When storing or transporting, place the unit back into the original packing box to avoid any
damage from moisture, dust, dirt, or chemical corrosion.
MAINTENANCE AND TROUBLESHOOTING
1. Maintenance
•Upon successful installation of the unit, user shall visit the manufacture’s website

HUGO USER MANUAL
REV 1.3
SAFEGUARD POWER SOLUTIONS
855.484.6797
PAGE | 16
(www.safeguardpowersolutions.com) to register the UPS under “Product Registration”.
Once registered, the UPS’s serial number will activate its warranty starting date.
•If the unit has not been activated by any power outage for a long period of time, it is
recommended to unplug the UPS from the main power source to allow the unit to
operate on battery mode until battery depletes. Once battery depletes, plug the unit
back to main power source to allow battery recharge. This maintenance shall be done
every 6 months for the battery to maintain its optimum performance.
•It is recommended to periodically unplug the UPS from the main power source to check
the UPS’s normal operation. If any fault is detected, read the LED indicator and note
the chirping sequence, then report this information back to point of purchase or consult
with the manufacture.
•Though no necessary, but it is strongly recommended to install any 3rd party surge
protection on the wall outlet where HUGO is plugged in. This added protection will also
prevent any HUGO board burnouts when city power is unstable.
2. Troubleshooting
Scenario: The unit does not operate in battery mode.
Possible Cause and Solution:
•Flow sensor installed: If the flow sensor is installed, the UPS will ONLY
operate when it detects cold-water flow. Turn on any faucet and check the
operating status of the UPS. If problem persists, unplug the “temp.flow”
port in front of the UPS panel to bypass the flow sensing loop. Once
unplugged, if the UPS’s operation is normal under battery mode, then
contact point of purchase to replace the flow sensor. If problem persists,
call the manufacture at 855.484.6797.
•Battery low voltage: Charge up the battery for a full 24 hours. If problem
persists, replace the battery. Battery can be purchased off-the-shelf, 12V,
35Ah, sealed lead-acid battery.
•Output overload: Remove the appliance connected to the UPS, wait for 5
minutes. Double check the connected appliance is rated under 350W. Plug
the appliance back into the UPS. Turn on the UPS.
•Output short circuit: Contact point of purchase or the manufacture for
inverter replacement if under warranty.
