Supplied Components (continued)
D The fluid filter (16) includes a 60 mesh (250
micron) stainless steel element to filter particles
from the fluid as it leaves the pump. It also includes
the fluid drain valve (D), which is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING on page 7).
D The gun filter/swivel (104) provides a final filtering
of fluid before it enters the gun, and allows greater
gun maneuverability.
D The suction hose (25) and tube (26) allow the
pump to draw fluid from a 5 gallon (19 liter) pail (K).
The strainer at the end of the suction tube keeps
large particles from entering the pump.
D The back pressure regulator (40) controls back
pressure to the gun and maintains proper circula-
tion pressure.
D The 3-way valve (45) allows you to circulate fluid
back to the pump or return it to the fluid container.
Fluid Heater
The fluid heater (51) heats the fluid as it passes
through, to maintain the correct spraying viscosity.
Read and understand all instructions in the supplied
heater manual 309524 before operating the heater.
WARNING
COMPONENT RUPTURE HAZARD
Heat causes fluid to expand. If the
heated fluid is trapped with nowhere to
expand, it can cause component rupture.
Be sure to keep the heated fluid circulating (turn
the 3-way valve to CIRC). Do not install a fluid
shutoff device between the heater and the gun.
