2012 Trip
Dump Station - A site where the waste (grey)
and sewage (black) tanks can be drained. In
most states it is illegal to drain waste tanks
anywhere other than at a dump station.
Dump Valve - Another name for the gate
valve used to drain the sewage (black) and
waste (grey) tanks.
Escape (Egress) Window - The formal name
for the emergency exit window located in the
motorhome. Egress windows are identified by
their red handles.
Full Hook-Up Site - A campground that has
city water, shore power and sewer hook-ups
or connections available.
Grey Water - Term associated with the waste
water holding tank. Water from the sink
drains, the shower and the washer-dryer (if
equipped) go into this tank.
House Battery - Powers 12 Volt DC lights
and accessories inside the motorhome.
HVAC - Heating, Ventilation and Air
Conditioning
LED (Light Emitting Diode) - Indicator
light.
Liquid Lead Acid Battery (LLA) -
A type of battery that uses liquid as an
electrolyte. This type of battery requires
periodic maintenance such as cleaning the
connections and checking the electrolyte
level.
Low Point Drain - The lowest point in
the plumbing. Drains are placed here so
water will drain out of the lower end of the
motorhome.
OEM - Original Equipment Manufacturer.
OHM - A unit for measuring electrical
resistances.
Ohm’s Law - Expresses the relationship
between Volt (E), amperes (I) in an electrical
circuit with resistance (R). It can be
expressed as follows: E = IR. If any two of
the three values are known, the third value
can be calculated by using the above formula.
Potable Water - Water that is safe for human
consumption.
Potentiometer - A device for measuring
an unknown potential difference or
electromotive force.
Pounds Per Square Inch Gauge (psig) -
Pressure measured with respect to that of the
atmosphere. This is a pressure gauge reading
in which the gauge is adjusted to read zero at
the surrounding atmospheric pressure. It is
commonly called gauge pressure.
Purge - The initial blast of air
(decompression) from the air dryer purge
valve at the beginning of the air compressor.
Purge Cycle - The time during which the air
dryer is undergoing purge and regeneration.
This cycle starts at the beginning of the
compressor unload cycle and normally ends
well before the beginning of the compressor
load cycle.
Regeneration - The mild backflow of air
through the air dryer and out the purge valve
that begins immediately after the purge
and lasts normally 10 to 15 seconds. This
backflow of air, from the air system and
through the air dryer, removes moisture from
the desiccant cartridge and prepares the air
dryer for the next compressor load cycle.
Roadside - The side of the motorhome that
faces the road while parked. Often called the
off-door side or the driver side.
SCA - Term for Supplemental Coolant
Additive. Chemical added to coolant for
diesel engines to help prevent cylinder liner
pitting and internal corrosion.
Shore Line - The electrical cord which runs
from the motorhome to the campground
120/240 Volt AC electrical supply.
Stinger - An arm attachment on a tow truck
that is used to lift the motorhome slightly for
towing.
Volt - The unit of measure for electric
potential.
Watt - The unit for measuring electrical
power, i.e. the rate of doing work, in moving
electrons by or against an electric potential.
Wet Cell Battery - A type of battery that uses
liquid as an electrolyte. This type of battery
requires periodic maintenance to clean the
connections and check the electrolyte level.
