STEP 4 Final Assembly
A) Complete all hydraulic plumbing.
B) Make sure suction lines are supported to prevent tank cracking.
C) Fill the reservoir until the oil level gets to the top blue line on the site level gage.
D) Set relief valve for system requirements.
NOTE: After the initial start up procedure you will need to add oil due to the hydraulic
lines filling up to capacity.
NOTE: Over-filling the reservoir will cause the oil to expand up through the breather
assembly when the oil warms up.
NOTE: We recommend using a high grade of hydraulic oil with a Pour Point of -50 F.
This will ensure proper oil flow during extreme cold weather operation. Use of
synthetic hydraulic oils is also recommended. Recommended Oil: AW32MV or
equivalent.
STEP 5 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 lines are plumbed and
properly tightened.
1) Slowly 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 level indication lines on the site level gage.
2) Check for hydraulic leaks and repair as needed.
3) Check for fan operation.
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. Using a Hydraulic Flow Meter Kit, set required pressure and flow rates to system
requirements.
7) Slow engine to idle and disengage the PTO.
8) System is ready for operation.
