STEP 6 START-UP PROCEDURES
The following steps are to ensure that the THERMAFLOW assembly is operating properly.
NOTE: Before engaging the PTO, make sure that all hydraulic and product lines are
plumbed and properly tightened.
1) Connect product hose to proper location so that system can circulate product back into the
tank.
2) Engage the PTO with engine at idle speed.
NOTE: Watch the oil level in the reservoir. Be ready to add more oil as needed to
maintain the oil level between the black and red lines on the site level gauge.
3) Check for hydraulic and product leaks and repair as needed.
4) Carefully Tach the product pump speed.
5) Slowly increase the engine speed until desired product pump speed is obtained.
6) Run system for at least five minutes to ensure that system is sufficiently cooling the
hydraulic oil. You should see approximately a 10-20°F rise in the hydraulic oil temperature
above the product temperature. This oil temperature should then be maintained throughout
the entire pumping cycle depending how long the system is run.
NOTE: If the hydraulic oil temperature is higher or lower than the 10-20°F rise, please
consult STAC, INC. at 800-334-7699. DO NOT OPERATE THIS SYSTEM UNTIL AFTER
YOU HAVE CONSULTED STAC, INC.
7) Slow engine to idle and disengage the PTO.
8) System is ready for operation.
STEP 7 OPERATING PROCEDURES

2) Set engine speed with the throttle control to the correct RPM.
NOTE: This system is self contained and there is no fan motor to operate.
3) To disengage the product pump either disengage any installed control valve or disengage
the PTO.
