Drying Cycle - The time during which
the air dryer cools, filters and removes
moisture from the air delivered by the air
compressor. The drying cycle begins and
ends the same as the compressor load cycle.
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 a dump
station.
Dump Valve - Another name for the
T-handle 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 rear of 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 motorhome.
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 that
water will drain out of the lower end of the
motorhome. Drains must be closed when
the water tank is filled.
OEM - Term for 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.
