HOLDING TANK HEATER
–If Equipped
Your coach may be equipped with black water
and gray water holding tank heaters to allow use
of waste utilities in freezing temperatures.
Holding Tank Heater Power Switch
Location:
•
Model 25T - Located on back of bath wall
near thermostat.
•
Model 25R - Located above thermostat near
rear TV.
The illuminated switch will glow when the
power is on.
DO NOT operate the holding tank heater
unless you are providing a supplemental 12-volt
power source to recharge the house/coach
batteries. This means either the shoreline cord
must be plugged into a 120-volt source, the
generator must be operating, or the chassis
engine must be running (such as when driving
down the road). This will prevent excessive
discharge of the house/coach battery.
NOTE: The holding tank heater pads are
electrical resistance-type heating
elements. This type of heating element
typically uses a large amount of current
while operating. If the tank heaters are
used without a recharging source, they
will drain the house/coach batteries in a
relatively short period. Typically, the
batteries would not support overnight
heating without a supplemental charging
source.
WATERLINE AND TANK DRAIN
VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system.
To open or close the drain valves, turn the
handles in the directions indicated by the
following illustration.
Drain valve locations are listed in the “Water
System Drain Valve Locations” chart at the end
of this section.
