TIFFIN MOTORHOMES –ALLEGRO® Chapter 3 HEATING & AIR CONDITIONING
Warning
Be cautious when washing the exterior of the motor home; water should never be
sprayed directly into the furnace vent. Should any water be forced beyond the rain
baffles into the furnace vent, the furnace may rust which, in turn, may cause
improper combustion and produce unwanted by-products of combustion.
Before the beginning of each travel season, the furnace should be thoroughly cleaned and inspected. Any obstructions,
debris, or lint which may obstruct free air flow or impede the operation of the air circulation system should be removed.
For example, accumulated dust or lint could possibly obstruct the orifices for the pilot light or may accumulate on the
blower blades and unbalance the operation of the blower. Additionally, any debris in the ductwork, when heated by
the furnace, could emit unpleasant odors or possibly become a fire hazard.
Consequently, the furnace system should be periodically cleaned; annually is recommended unless the motor home is
subjected to dust levels significantly greater than average; in which case more frequent cleaning is recommended.
The Owner's Information Package provides recommended cleaning tips and procedures; when needed, a more
thorough cleaning should be performed by a qualified service technician.
Air Conditioning System
It is designed for 120 VAC power supplied either from the external power cord or from the generator. Any unnecessary
heat loading (e.g., exposure to direct sunlight for long periods of time; transmittance of sunlight through the windows)
will work the air conditioning system harder and may compromise the desired results. Accordingly, if the air
conditioning system is to be used, park the motor home in a shady location whenever possible and close drapes on
those windows exposed to direct sunlight. Additionally, any heat-producing sources (e.g., oven, unnecessary lights)
within the motor home will work against the air conditioning system; so strive to minimize their use.
The air conditioning system is the major consumption device of electrical power in the motor home. When this system
is being used in an RV park, cumulative use of these air-conditioning systems by the resident vehicles can create a
bigger demand for electrical power than is actually available. Accordingly, at times a "brown-out" condition may
arise—this is when the AC voltage normally available drops to a lesser value (e.g., 10-20% below normal or more).
"Brown-out" conditions cause appliances to draw greater currents to make up for the reduced voltage; thereby causing
circuit breakers to trip or fuses to blow. Under such conditions, your own motor home is not at fault; simply reset your
breakers and/or replace your fuses. Should such conditions continue, one may wish to turn reduce the electrical load (in
this case, turn "off" the air conditioning system for awhile) or start the electrical generator.
