Operation
1. Select fluid to use for heating circulation.
•
50% water and 50% ethylene glycol mixture is rec-
ommended for fastest heat-up time and prevention
of algae build-up regardless of ambient tempera-
ture.
•
Oil can be used but heat-up time will increase and
the hopper fill level must be decreased. See step 2.
NOTE: Detailed diaphragm pump operating instruc-
tions are in the Husky 205 diaphragm pump manual
308652.
2. Fill heating fluids in double wall hopper outer cavity.
See manual 312747 for instructions.
Do not plug top ports. Always have venting fittings
installed to prevent outer cavity pressurization. Failure
to do so may cause leakage into spray material.
If oil is selected as the heating oil, the maximum oil
level must be 3 in. (76.2 mm) below the hopper side
port level. A higher fluid level may cause the oil to
overflow during initial pump and heater startup due to
thermal expansion.

NOTICE
NOTE: If using heated hose: each 50 ft (15.2 m)
heated hose section holds approximately 1.25 gal-
lons (4.7 liters) of fluid.
3. Pump Setting: Set the flow rate of the circulation
fluid by opening the pump needle valve (211)
45°-60° open until the pump cycles 60-80
cycles/min (0.7-1.0 gmp or 2.6-3.8 l/min).
NOTE: Do not use a higher flow rate--doing so will
decrease system heating performance and pump
life.
4. Heater Setting: Adjust the heater thermostat to the
desired circulation temperature. The setting at the
heater output thermometer should be about 10° F
(6° C) higher than the desired paint temperature.
Never exceed the XP System's 160° F (71° C) max-
imum fluid temperature rating. See Viscon HP
heater manual 309524 for instructions.
As a general guideline, heater knob settings are #7
for 105° F (40° C), #8 for 135° F (57° C) and #8 1/2
for 150° F (65° C).
NOTE: If the hose heat is not being used for more
than one hour, shut off Viscon HP heater and circu-
lation pump to lengthen heater life.
