Storage and Winterization
Important: (Failure Will Void Warranty)
• Due to the integrated mechanical and electrical over-temperature shut-off devices, Hydro Heater
TM
unit will not
produce water that continuously exceeds 145°F. The burner will simply cycle off while the water keeps flowing for your
convenience. The burner will cycle back on when internal water temperatures reach about 140°F.
• Hydro Heater
TM
unit is ideal for many outdoor activities. Savu supports the Leave No Trace Principles that encourage
minimal impact to the environment while camping. You’ll find that less soap is necessary with warm water than with
cool or cold water, so use small amounts of biodegradable soap. Please dispose of your gray water responsibly. Wash
yourself 200 feet away from streams or lakes to avoid soap run-off finding its way to a natural water source. Contact your
campground or park to learn about their specific gray water disposal policy.
• Hydro Heater
TM
unit will typically run continuously on one full battery charge for 2-3 hours. Make sure to pack sufficient
propane fuel for the duration of your outing. Maintaining your battery at or near full levels will increase the life of your
battery.
•
Continuous operation of water heater at warm setting for 20 minutes may cause the propane cylinder to freeze up. Let
the cylinder thaw or replace with a fresh propane cylinder.
Helpful Hints
Maintenance
CAUTION:
WARNING: If the outside temperature is around or below freezing (32 degrees F, 0 degrees C), ensure
that the drain valve is opened and water drained from the portable tankless water heater after each use to avoid internal
damage to the water regulator. You will also need to unhook the outgoing and incoming water lines to ensure that any
water in the heat exchanger is drained. Failure to properly drain your portable tankless water heater will cause water
damage which may or may not be reparable. Please check the warranty information
