CAUTION
Operation of the circulating pump
for any amount of time without fi rst
bleeding will result in equipment
damage.
If fl uid temperature exceeds 150 F
during start-up and no fl ow has been
established, discontinue start-up and
contact Fulton Service Department.
Failure to do so may cause equipment
damage.
Circulating Pump
Adhere to the following:
1. Read manufacturer’s instruction manual thoroughly. If the pump is
supplied by Fulton Thermal Corporation, manufacturer’s literature is
included with this manual.
2. Never run the pump without fl uid in the casing. For pumps equipped
with mechanical or air-cooled seals, air must be bled out of the stuffi ng
box area to ensure that thermal fl uid has lubricated all seal and bearing
areas. Operation of the pump even a short time without bleeding fi rst will
damage the pump.
3. Use the thermal fl uid as a barrier fl uid. Remove the 3/8” plug at the barrier
fl uid fi ll port. Fill the cavity with thermal fl uid until it comes out of the
overfl ow tube. Replace the 3/8” plug.
 Pump With Mechanical/Air Cooled Seal
Adhere to the following:
1. Open the air bleed connection located directly over the pump shaft.
Replace plug when a steady stream of thermal fl uid, free of entrained air,
fl ows from the port.
2. If fl ow has not started after two to fi ve minutes, remove the coupling
guard and rotate the pump shaft by hand in the proper direction. This
should help move the cold viscous fl uid through close tolerance seal areas.
Replace plug when fl ow is steady.
3. If this fails to induce fl ow, introduce fl uid through the bleed port and rotate
the shaft by hand to work the fl uid around the seal area. Continue to add
fl uid and rotate the shaft until no more fl uid can be added.
4. Replace the plug and run pump for fi ve to ten seconds. Stop the pump,
remove the plug and wait for fl ow to start. If after two minutes fl ow has
not started, add more fl uid as described above and run the pump for fi ve
minutes.
5. Constantly check the bearing area (located immediately behind the casing)
for overheating. Remove the plug and check for fl ow.
6. If fl ow has not started at this point, the fl uid may be too viscous to move
through the seal area. Start the system normally by selecting heat on the
control panel, and raise the temperature 50°F. Continue to raise the system
temperature by 50°F increments. Keep checking the pump until fl ow starts.
NOTE:

If at 150°F there is no fl uid fl ow, discontinue Start-up procedures and
contact the Fulton Service department immediately.
7. The pump should not be subjected to thermal or pressure shock. The thermal
fl uid should, therefore, be allowed to fl ow into the casing slowly.
