RV WINTERIZATION
Winterizing means getting your RV ready for the freezing
temperatures that come along with winter in most places.
It happens when you want to store your RV for a few months
while it's too cold to travel. Winterizing's objective is to prevent
the freezing damage to Fresh Water Lines, Waste Drain Lines,
Waste Holding Tanks, Water Heater and batteries.
You will want to winterize your RV in two different
scenarios : When storing your RV for the winter and very cold
weather camping.
When storing your RV, use the same precautions as you
would in your home in regard to perisables , ventilation ,
winterizing and rain protection. If you are leaving your RV
unattended for a prolonged time you should flush out all drain
lines and waste holding tanks .
It is crucial to know the importance of winterization and how
it will affect your RV if you don't do it. If you don't winterize your
RV, you could end up with a burst pipe because water will freeze ,
expand in your hoses and potentially explode . Winterizing
will protect your water pump and avoid a malfunction and
damages within your water/holding tank systems.
Using a Non-Toxic Antifreeze approved for drinking to
water lines would do the job for winterizing protection for your RV.
ӹ
System Coolant
•
The system coolant does not require winterization
•
The system coolant can be tested for its freeze protection
value.
ӹ
Domestic Water System:
•
The domestic water circuit needs to be drained or protected
using RV winterizing fluid.
•
Draining is accomplished by opening the low point drains
and blowing air through the water system.
•
Propylene-glycol can be pumped through the system using
the domestic water pump and opening both hot and cold
valves. Using this procedure does not require draining the
Demand Hot Water exchanger.
•
Propylene-glycol can be pumped through the system
using the domestic water pump and opening both hot and
cold valves at a plumbing fixture. Using this procedure does
not require draining the Demand Hot Water exchanger.
STEPS FOR WINTERIZING
1. Drain all holding tanks (Fresh, Grey, and Black)
2. Pour a non-toxic RV water system antifreeze into the fresh
water tank (4 gal).
3. Turn on water pump and run the water pump until the
non-toxic antifreeze solution fills the water lines.
4. Run each sink faucet in the cold and hot position until
steady stream of antifreeze is flowing out for 10 seconds.
Run anti-freeze down the shower drain for 10 seconds
as well.
5. Flush toilet and hold pedal down until steady steam of
antifreeze is coming out.
6. Open exterior shower faucet until the non-toxic antifreeze
emerges from the hose, shut off the valve and remove the
drain valve/hose assembly .
While the water is draining from all of the faucets and
system.
ӹ
You may remove, drain and store the exterior components
that you've previously attached to your RV (such as hoses
and/or shower heads).
7. Shut off the pump when the non-toxic antifreeze has been
distributed throughout the system.
Grech RV recommends that approximately twice a year or after a long
period of time of storing your RV to give a check-up and cleaning of
the gas-operated appliances.
NOTICE
Please disconnect the current to all chassis electric consumers using
the battery isolator switch if the vehicle sits for long periods or for
more than 2 months. The battery isolater is located on the right of the
accelerator pedal in the driver's foot well. Slide the red release down
and pull it off the post. This will save jump starts, battery charge ups,
and possible battery damage and replacement. The Mercedes-Benz
Sprinter Operator's Manual describes its location, operation and
cautions in detail.
NOTICE
Drain valves are located on the driver side of the unit in front of the
rear tires.
