Introduction
ULTRA
PLUS+
1000 BASIC COMPONENTS
Your new sprayer functions and operates differently than
other airless paint sprayers. This section will help you be-
come familiar with the sprayer before operating it.
Pressure Control
The pressure control includes an ON/OFF switch for the
sprayer, a pressure adjusting control knob and a freeze
resistant pressure sensing device. The function of the
pressure control is to control the motor speed so that the
sprayer maintains constant fluid pressure at the pump
outlet.
Pressure Drain Valve
The pressure drain valve provides pressure relief of the
sprayer. In the forward position, the drain valve is closed
and allows normal sprayer operation. In the downward
position, the pressure drain valve relieves the pressure
in the system. The pressure drain valve will also open au-
tomatically in the case of a control overpressure failure.
Motor
The DC motor has sealed bearings and replaceable mo-
tor brushes. It drives the displacement pump at the rate
needed to supply sufficient paint volume at the selected
pressure. W orking 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 may hum intermittently un-
til the fluid pressure stabilizes, then the motor will shut it-
self off. However, there will still be power to the sprayer
and it will stay pressurized and ready to use until you
manually shut it off and relieve pressure.
Because the motor is DC, it is less sensitive to low volt-
age or voltage fluctuations than an AC motor, and a 12
gauge or larger extension cord of up to 300 ft. (90 m) can
be used without performance loss.
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
Graco Throat Seal Liquid, helps prevent damage to the
throat packings and piston rod.
Fluid Filter
The fluid filter strains the paint to help avoid clogs in the
hose and spray tip. The filter includes a reusable element
and has a pressure drain valve for manually relieving fluid
pressure.
Hoses
The grounded, nylon spray hoses have spring guards on
both ends. The 50 ft. (15.2 m) hose has a 1/4 in. ID. The
3 ft. (0.9 m), 3/16 in. ID hose provides more flexible gun
movement. The nylon hose material acts as a pulsation
dampener to absorb pressure fluctuations.
Spray Gun & RAC IV DripLess Tip Guard
Graco high pressure spray guns have a safety latch
which prevents accidental triggering when it is engaged.
See
T
in Fig. 1. The gun provided with the sprayer also
has a filter for final paint straining. The Reverse-A-Clean
IV SwitchTip uses high pressure fluid to remove clogs
from the spray tip without removing it from the gun. The
Reverse-A-Clean IV DripLess tip guard is a safety fea-
ture which helps reduce the risk of fluid injection injury.
