Section 2 - Paint Hog Systems
The pneumatic pumps are powered by unfiltered
compressed air at manifold pressure that is acti-
vated by a manual valve at the pump. Other valves
near the pump inject and discharge freshwater to
flush out the pump and lines when filling opera -
tions are completed. Refer to the Operation sec-
tion for instructions on operating the pumps and
filling the tanks.
2.9 Pressurized Flush Water System
The water tank is mounted on the deck near the
paint tanks. The tank capacity is 30 gallons (113.5
liters) and is pressurized by the filtered air system.
A manifold, supply hose and red 3/8” lines de-
liver water under pressure to paint lines, filters,
pumps and other components that require flush -
ing. Manual or pneumatic valves at each injection
point turn water flow on and off. Quick connect
fittings with manual on/off valves on the sides of
the deck and on the rear platform provide con-
nections for a water hose.
The following is a description of water tank com-
ponents and their function.
1. Pressure Gauge - Displays water tank pres-
sure. Tank pressure is set with a pressure
regulator valve in the rear control console.
2. Pressure Supply Valve - Delivers filtered
pressurized air to the water tank. A regula-
tor in the rear control console controls tank
pressure.
3. Exhaust Valve - Used to purge air pressure
from the tank. Always turn the valve off when
all pressure is relieved from the tank.
4. Exhaust Muffler - Quiets exhaust air flow
during purging to prevent excessive noise and
hearing damage.
5. Pressure Relief Valve - An automatic valve
that prevents excessive pressure in the tank.
It should checked periodically for proper op-
eration.
6. Sight Cap - This cap is secured with cam
locks and can be removed to check the water
level and fill the tank before operations. Tank
pressure must be completely purged before
removing this cap.

WARNING
NEVER ATTEMPT TO REMOVE THE SIGHT CAP WHILE THE
WATER TANK IS PRESSURIZED. PRESSURE IN THE TANK
WILL MAKE THE CAP DIFFICULT TO REMOVE AND WILL
BLOW THE CAP FROM THE TANK UNEXPECTEDLY DURING
REMOVAL. THIS COULD RESULT IN SERIOUS INJURY OR
EVEN DEATH TO PERSONNEL AND DAMAGE THE TANK.
