pressure in the air system.
Curbside - This refers to the side of the motorhome which faces the curb when it is parked. Often
called the door side or the passenger side.
Current - The rate of fl ow of electricity or the movement rate of electrons along a conductor. It is
comparable to the fl ow of a stream of water. The unit of measure for current is the ampere.
Cut-In Pressure - The pressure level in the air system supply tank which triggers the compressor
load cycle. May apply to some water systems, such as water pump, accumulator tank, etc.
Cut-Out Pressure - The pressure level in the air system supply tank which triggers the compressor
unload cycle. May apply to some water systems, such as water pump, accumulator tank, etc.
Cycle - In a battery, one discharge plus one recharge equals one cycle.
Desiccant - A granular substance that has a high affi nity for water and is used to retain moisture from
the air stream fl owing through the air dryer cartridge.
Direct Current (DC) - Power that is stored in a battery bank or supplied by photovoltaics, alternator,
chargers and DC generators. Direct current is also known as battery power.
Drain Trap - This is a curve that is in all drains. Water is trapped in the curve and this creates a
barrier so tank odors cannot escape through the drain.
Dry Camping - Camping in the motorhome when there is no city water hook-up or shore power.
In other words, using only the water and power that is in the motorhome and not from another
source.
Drying Cycle - The time during which the air dryer cools, fi lters 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 at 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 window located in the rear of the
motorhome. Egress windows can be easily identifi ed by their red handles.
Full Hook-Up Site - A campground that has city water, shore power and sewer hook-ups or
connections available.
