Your new Ultimate NovaTM 1000 Sprayer functions and
operates differently than other airless paint sprayers.
This section will help you become familiar with the
sprayer before operating it.
Pressure Control
The pressure control includes an ON/OFF switch for the
sprayer, the pressure adjusting control knob, a pressure
sensing device, and a current overload circuit breaker
with a manual reset button. Its function is to control the
motor speed so that the sprayer maintains constant
fluid pressure at the pump outlet.
Motor
The DC motor has sealed bearings and replaceable
motor brushes. Its function is to drive the displacement
pump at the rate needed to supply sufficient paint
volume at the selected pressure.
Working together, the pressure control and motor
cause the pump to cycle whenever there is fluid or
pressure demand. When the pump is cycling, the motor
sounds like an automobile starter cranking. When the
pump is not cycling, the motor hums, hums intermit-
tently, or appears to have shut itself off. However, there
will still be power to the sprayer and it will stay
pressurized and ready to use unless you manually shut it
off and relieve pressure.
Because the motor is DC, it is less sensitive to low
voltage or voltage fluctuations than an AC motor, and a
heavy gauge extension cord of up to 150 feet (45 ml
can be used.
Drive Assembly
The sealed drive assembly transfers power from the DC
motor to the displacement pump.

Displacement Pump
The positive displacement, volume-balanced pump pro-
vides equal fluid delivery on both the up and down
pump strokes. The pump has a wet-cup which, when
filled with Grace Throat Seal Liquid, helps prevent
damage to the throat packings and piston rod.
Hoses
The grounded, nylon spray hoses have spring guards on
both ends. The 50 foot (15.2 ml hose has a l/4 in. ID.
The 3 foot (0.9 ml, 3/16 in. ID whip hose allows flexi-
ble gun movement. The nylon hose material acts as a
pulsation dampener to absorb pressure fluctuations.
Spray Gun 8 Reverse-A-Clean@ Ill Spray Tip
The high pressure spray gun has a trigger safety which
prevents accidental triggering when it is engaged (see
below). The Reverse-A-Clean Ill spray tip uses high
pressure fluid to remove clogs from the spray tip
without removing it from the gun. It includes a safety tip
guard which helps reduce the risk of injection injury.
