Operation
1. Select fluid to use for heating circulation.
• 50% water and 50% ethylene glycol mixture is
recommended for fastest heat-up time and pre-
vention of algae build-up regardless of ambient
temperature.
• Oil can be used but heat-up time will increase
and the hopper fill level must be decreased. See
item 2.
NOTE:
Detailed diaphragm pump operating instructions are in
the Husky 716 diaphragm pump manual 308981.
2. Fill Heating Fluid in double wall hopper (C) outer
cavity. See manual 312747 for instructions.
NOTE:
If using heated hose: each 50 ft. (15.2 m) heated
hose section holds approximately 1.25 gal. (4.7
liters) of fluid.
3. Set the flow rate of the circulation fluid by adjusting
the pump’s air regulator (9) until the pump cycles
about 50 cycles/min. Do not use a higher flow rate
as doing so will decrease system heating perfor-
mance and pump life. Never exceed the hose’s
95 psi (0.6 MPa, 6.6 bar) maximum working pres-
sure rating.
4. Adjust the heater thermostat to the desired circula-
tion temperature. The setting at the heater output
thermometer should be about 10° F (6° C) higher
than the desired paint temperature. Never exceed
the hose’s 140° F (60° C) maximum temperature
rating.See Viscon HP heater manual 309524 for
instructions.
NOTE:
If the hose is not being used for more than one hour,
shut off Viscon HP heater and pump to lengthen heater
life.
NOTICE
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.
NOTICE
If oil is the heating fluid selected, 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.
