8� Shut the water pump OFF once all the lines are
full�
9� OPEN all the faucets and leave them open�
10� DISCONNECT the hose, rinse it out with fresh
water and store�
WARNING
Remove all RV antifreeze spillage from all sinks,
drain pans, and faucet parts after winterizing.
Failure to do so could damage surface finishes. Do
not use water to rinse antifreeze down the drain as
it will dilute the antifreeze.
11� Complete step 11 from the previous set of
instructions on winterization by proceeding to the
Volta System Storage section in this manual and
complete the steps for short or long term storage;
see Volta System Storage on page 9-12 �
Water Heater Winterizing
If the touring coach is to be stored during winter
months, the water lines must be drained to prevent
damage from freezing� Once drained, the water lines
can be “blown out” by applying air pressure at the city
water inlet or RV, non-toxic antifreeze can be added�
The water heater only holds a couple of cups of water
in the heat exchanger, which is drained with the low
point drain valves�
Macerator Pump Winterizing
Plan your winterizing and storage ahead, and be sure
the holding tanks are drained and flushed thoroughly.
This is very important, as the frozen sewage and water
could seriously damage the system� After dumping
the tanks, add RV, non-toxic antifreeze to one of the
holding tanks and start the macerator pump� Run the
pump until the RV, non-toxic antifreeze comes out the
end of the pump hose, then close the dump valve� As
extra protection, open the toilet valve and add RV, non-
toxic antifreeze through the toilet into the Black Water
tank and pour RV, non-toxic antifreeze into a sink drain
to protect the holding tanks, valves, and pump from
residual water freezing�
Volta System Storage
Long Term Storage (Greater than 3 months)
Preparations should be made to protect the life
and performance of the Flex Pack when not in use�
When leaving the vehicle in storage, turn OFF the
Volta System by pressing the Battery Power On/Off
pushbutton�
To prepare for long-term storage:
1� Fully charge the house battery (Flex Pack), or at
minimum charge to above 70%�
2� Press the Battery Power On/Off pushbutton and
verify that the pushbutton LED and touchscreen
turn off, indicating the Volta System is off�
3� Turn on the Volta System every three months
to verify the pack is maintaining a high State-of-
Charge (SOC)� If necessary, charge the system to
above 70% SOC before storing the vehicle again�
WARNING
Failure to turn off the Volta System before storing
your vehicle long term (greater than 3 months) will
cause the Flex Pack(s) charge to deplete faster,
even if all loads on the system are removed, which
can cause permanent damage to the Flex Pack.
WARNING
Do not store the Volta System at low State-of-
Charge. The system is designed with a limited
energy reserve, in case the system is left on and
the low voltage shutdown occurs. This reserve
may last for three months until irreversible damage
could occur. Neglecting system maintenance and
allowing the Flex Pack to come to this state will
result in voiding the warranty.
WARNING
To protect the Flex Pack, avoid using or storing
the Flex Pack at or above 134°F (57°C). Storage
of the Flex Pack at elevated temperatures is not
recommended, as it will reduce the lifetime and
capacity of the Flex Pack.
NOTE
It is possible to leave the touring coach plugged in
for long-term storage, but it is unnecessary to do
so with a full charge or greater than 70% charge,
following the instructions above.
