1-8. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - cont.
Unit Components. Refer to figure 1-1.
CANVAS COVER (1). Protects unit from weather. Rolled and strapped up during normal operation.
R.O. PRESSURE TUBES (2). Four tubes with eight internal reverse osmosis elements reduce total dissolved solids
from filtered water to produce drinking water.
JUNCTION BOX (3). Contains circuit breakers, overload heaters, motor starters, relays, etc. Provides connection
of external power for operation of the unit.
CONTROL PANEL (4). Contains meters, gages, valves and hose couplings. Connects accessory items and hoses
to ROWPU. Controls system operation.
GROUND ROD (5). Driven into ground and attached to ROWPU to keep operators from getting electric shocks
from power source or static electricity. Stored on control pane1 when not in use.
CONTROL BOX (6). Contains switches to control all pumps and panel lighting.
WATER METER (7). Measures total number of gallons of product water produced by the unit.
TRAILER (8) (Models WPES-10 and H-9518-1 only).
Serves as operating and transportation platform for the
COVER PLATE (9). Provides support for canvas cover.
CARTRIDGE FILTER (IO). Provides additional filtering (second stage) of water coming out of the multimedia
PULSE DAMPENER (11) (Models WPES-10, WPES-20, and WPES-30 only). Removes pulses from high pressure
water to protect R.O. elements.
R.O. PUMP ASSEMBLY (12). Consists of electric motor and high pressure pump. Applies high pressure to
system water for operation of reverse osmosis process.
MULTIMEDIA FILTER ( 13). Provides first stage filtering of raw water.
CHEMICAL FEED PUMP ( 14). Pumps chemicals from chemical cans into water being processed.
BOOSTER PUMP (15).
Forces water from multimedia filter through the cartridge filter and provides a positive
