Instruction for Initial Start-Up of Non-Pressurized Supply Tank
Remove the fill port plug for the supply tank located on top of the system.
Fill the supply tank to the top of the sight glass with fluid.
With controller set at minimum temperature, press and hold the start button and the air
purge button until the fluid is discharged from the tank. Note: On systems equipped with
auto air purge pushing the air purge button is not required.
Repeat steps 2 and 3 until the system is full.
Final fluid level should be at the top of the sight glass.
Replace and seal fill port plug.
With controller at minimum temperature, start system and observe pump pressure gauge.
Gauge reading should be steady. If fluctuations in needle are noted, press air purge button
to remove trapped air and system’s gauge reading is steady. Operate system at the
minimum temperature for 10 minutes, observing gauge to insure all trapped air is removed.
Check system and process for water or air leaks.
Recheck fluid level. Adjust if necessary.
Note: Please refer to Section 1.6 if overhead piping will be required.

Instructions for Initial Start-Up of Pressurized Supply Tank
Remove the fill port plug for the supply tank located on top of the system.
Note: Do not add air into the tank until step 7.
Fill supply tank to the top of the sight glass with fluid.
With controller set at minimum temperature, press and hold the start button and the air
purge button until the fluid is discharged from the tank. Note: On systems equipped with
auto air purge pushing air purge button is not required.
Repeat steps 2 and 3 until the system is full.
Final fluid level (without air pressure in the system should be at the top of the sight glass).
Replace and seal fill port plug.
Connect the air supply. Air supply line should be equipped with shut off valve to allow
removal of supply line after pressurization
o
Verify the air pressure regulator setting:
35 – 40 psi for units with 250
F maximum temperature.
60 psi for units with 300
F maximum temperature.
Remove air supply line.
With controller at minimum temperature, start system and observe pump pressure gauge.
Gauge reading should be steady. Fluctuations in needle are noted, press air purge button to
remove trapped air so that system’s gauge reading is steady. Operate system at the
minimum temperature for 1 minute, observing gauge to insure all trapped air is removed.
Check system and process for water or air leaks.
Recheck fluid level air pressure. Adjust if necessary.
