To use the city water fill
1. If needed, sanitize the water system.
2. Remove the connection cap and attach a
non-toxic drinking water hose to the inlet.
3. Turn ON the water at the water source.
4. Enter the RV and open the cold water
supply faucets to bleed air from the water
lines.
5. The water heater will fill first, followed by
the supply lines and faucets.
When the water lines are nearly full, you
may experience some "air pockets." Allow
them to escape before closing the cold
water supply faucets.
The fresh water connection should be
unplugged (i.e., the non-toxic drinking
water hose disconnected) when the RV is
left unattended for any amount of time. If
something would happen to the water
system, this may help limit water damage
to a smaller area.
To disconnect the city water fill
6. Shut OFF the water at the water source.
7. Disconnect the non-toxic drinking water
hose and reinstall the connection cap.
To reduce the chance of contamination,
prevent the non-toxic drinking water hose
from coming into contact with the ground.
Reinstall the connection cap when the fresh
water connection is not being used. Do not
remove the following label from your RV:

Dry camping
You can gravity fill the fresh water system if
you do not have access to city water;
however, allow extra time to fill the fresh
water system if you are using this method.
Follow the steps listed above; however, at
step 3 put the other end of the non-toxic
drinking water hose into your container of
fresh water, and turn ON the water pump
(instead of turning ON the water at the water
source.) When the fresh water tank is full,
shut OFF the water pump and disconnect the
non-toxic drinking water hose.

Excessive pressure from water supply
systems may be encountered in some parks,
especially in mountain regions. Water
pressure regulators are available to protect
your system against such high pressure. A
regulator of this type is recommended to
prevent damage to the plumbing system or
components. Water pressure regulators
(customer supplied) are available from your
Dealer to protect the RV plumbing system
against such high pressure.

Once activated, the water pump (also known
as the on-demand pump) will self-prime, and
provide water. The water pump continues to
run until approximately 45 lbs. of pressure is
achieved and shut off. The water pump will
automatically re-start when pressure drops.
Some cycling may occur, depending on the
volume of water being released. The water
Not using a water pressure regulator when
using city water may cause the o-rings to
fail. To prevent damage to the plumbing
system or components when using the city
water connection, a water pressure
regulator rated for 40 lbs. is
recommended.
