Operation
Operation
1.Select fluid to use for heating circulation.
•50% water and 50% ethylene glycol mixture is recommended for fastest
•Oil can be used but
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.
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.
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.
