Operation
5-2
•
Toggle the pump switch (4-1) to the “On” (up) position
and run the pump. This will release the air from the
system.
•
Monitor the “heat transfer fluid level gauge” (5-1) and
make sure that the heat transfer fluid level stays between
1/4 to 3/4 full at all times during this process.
•
Note that there may be a certain amount of air in the
system. “HTF” levels may change as air is displaced from
the system. Add “HTF” fluid to maintain 1/4 to 3/4 levels.
• When the air is eliminated, the “Pump Pressure” gauge
(6-1) will hold at a steady reading of between 25 to 35
