Heat causes fluid to expand. If fluid in the heated por -
tion of your system is trapped with no where to ex-
pand, it can cause a system rupture. A system rup-
ture can result in serious bodily injury and property
damage.
Be sure your system has an adequate way
to handle heat expansion.
 Use flexible hoses between the heater and gun
or, install a properly sized accumulator down-
stream
from the heater
or, install a pressure relief valve, pre–set to re-
lieve pressure when it exceeds the system’ s
maximum
working pressure
and, never install any shutof f device between the
heater and gun. If you are using a fluid regulator
before the gun, never use it as a shutof f device.
WARNING
The Viscon Heater must be installed by a qualified
electrician in compliance with all state and local
codes and regulations, to reduce the risk of electric
shock
or other serious bodily injury during installation

on page 5, and remove the spray tip from
the gun. Always use the lowest possible fluid pres-
sure, and maintain firm metal-to-metal contact be-
tween
the gun and the pail during flushing to reduce
the risk of fluid injection, static sparking, and splash -
ing
in the eyes or on the skin
WARNING
Starting and Adjusting the Pump
Be
sure the air regulator and bleed–type master air valve
are closed. DO NOT INST ALL THE SPRA Y TIP YET!
Place the suction tube (21) in the fluid pail. Open the
bleed-type master air valve. Hold a metal part of the
spray gun firmly to the side of a grounded metal pail and
trigger the gun. Slowly open the air regulator until the
pump
starts. Allow the pump to cycle slowly until all the air
is pushed out of the fluid lines. Release the gun trigger
and engage the safety latch; the pump will stall against
the
pressure.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun is triggered and released.
Follow the Pressure Relief Procedure W arning on
page
5, then install the spray tip in the gun.
Use the air regulator to control the pump speed and fluid
pressure. Always use the lowest pressure necessary to
achieve
the desired results. Higher pressures waste fluid
and cause premature wear of the pump packings and
spray
tip.
Keep the wet-cup filled with Graco Throat Seal Liquid
(TSL) to help prolong the packing life. Check the tight-
ness of the packing nut weekly. The packing nut should
be tight enough to prevent leakage – no tighter. Always
follow
the Pressure Relief Procedure W arning on page
5 before adjusting the packing nut or adding TSL.
Never allow the pump to run dry of the fluid being
pumped. A dry pump will quickly accelerate to a high
speed, possibly damaging itself. If your pump acceler-
ates
quickly , or is running too fast, stop it immediately and
check the fluid supply . If the supply container is empty
and air has been pumped into the lines, refill the supply
container and prime the pump and lines with fluid, being
sure to eliminate all air from the fluid system, or flush the
pump as described in Shutdown and Care , following.
Heated Systems
Operating instructions for a heated circulating system
are provided in the V iscon Heater manual, 307-805.
Read
and understand all warnings and instructions in the
heater manual before operating a heated system.
In circulating systems, adjust the back pressure regulator
(33) and pump air regulator (16) to obtain proper spray
pressure at the gun and maintain suf ficient circulation
flow
to prevent fluid settling.
The three-way ball valve (30) selects either fluid circula -
tion
or draining. T o circulate fluid back to the pump, turn
the handle toward the CIRC end of the valve. T o drain
fluid,
turn the handle toward the DRAIN end.
Shutdown and Care
Always follow the Pressure Relief Procedure W arning
on page 5 whenever you shut of f the pump. Stop the
pump at the bottom of its stroke to keep fluid from drying
on the exposed displacement rod and damaging throat
packings.
Always
flush the pump with a compatible solvent before
the fluid can dry on the displacement rod, and at the end
of each day . If you are pumping water-based fluid, flush
first with water and then with mineral spirits. If you are
pumping oil-based fluids, flush with mineral spirits only .
Relieve pressure and leave the mineral spirits in the
pump
to prevent corrosion.
