The drainage system, including the tanks and associated drain piping should be
periodically inspected for loose fittings from vibrations. Any deterioration of the sealant
around joints and fittings should be repaired immediately.
Check the operation of the termination valves. If they pull or close with effort, lubricate the
shaft and slide valve with spray silicone. Termination valves that leak should be repaired
or replaced as soon as possible.
Sometimes, a buildup of paper or other material in the inside groove of the termination
valve can obstruct the valve and cause it to seat improperly. If you suspect that this is
occurring, the valve can be removed from the drainage line by removing the four screws
that hold it in place and sliding it out. The valve groove may then be cleaned out with a
screwdriver or similar tool. Replace the valve in the line and reinstall the screws to secure
it in place.
It is recommended that fresh water not be left in the storage tank for long periods of
time. The water should be drained when the unit is being stored or not in use. Drains
are located in a variety of compartments. To drain the tank and lines, simply open the
low point drains and allow water to run out. After water has drained, close the valves
to prevent pests from entering the system. See also “Sanitizing the System” in Chapter
6 - “Plumbing Systems” (page 39) for more information. Check all hoses, fittings, and
connections regularly for leaks and signs of wear. Make sure to keep the system sanitized,
and take care to winterize during cold weather.
The electrical system requires minimal maintenance under normal circumstances. Most
electrical maintenance in the recreational vehicle involves the chassis and auxiliary
batteries. Keeping the batteries properly maintained will help to eliminate many
frustrating electrical problems. For example, 12 Volt power is needed for the furnace,
refrigerator, water heater, and some air conditioner functions.
The generator is another area in which simple preventive maintenance can head off
problems before they happen. Read the manual supplied with the generator in the
Owner’s Information Kit for the care and maintenance required on a regular basis.
If you experience electrical problems with your recreational vehicle, make sure to have it
checked by an authorized Thor Motor Coach dealer or a qualified RV technician.
Generator power plant service, recommended by the generator manufacturer, should be
performed at an authorized service center. Routine or emergency service, such as adding
oil, changing filters, or replacing spark plugs, could be accomplished at an auto service
center, but must be done in accordance with the service instructions specified by the
generator manufacturer. Refer to the Generator Owner’s Manual for further information.
The propane system should be checked regularly for leaks and road damage. Follow
the lines, looking for kinks or flattened spots that may have occurred during travel or
maintenance on the recreational vehicle. A qualified propane service technician using
proper equipment should check the entire system annually or whenever you suspect a
problem.
The line pressure for propane appliances should be checked at least every six months.
Most propane suppliers have this equipment to do the test for you.
All service procedures should be performed only by a certified
propane service technician.
Insects can build nests in the burners of the various appliances and equipment. The
burner and burner orifice of the propane appliances should be cleaned out by an
authorized dealer or repair facility anytime circumstances or conditions warrant, but no
less frequently than on an annual basis.
