9.3.8 Top Suction Kit Testing
Tools Required:
Tools Required:
Adjustable wrenches, alligator clips
Top Suction Kit Function:
Save time/money and increase reliability when delivering fuel from the top of various types of
tanks. An EnergyLogic Top Suction Kit combines fuel pick-up with a foot valve and a low fuel
cut off switch. The fuel pick-up line has a copper tube, increasing reliability of the fuel delivery.
An EnergyLogic Low Fuel Cutoff Switch is provided to interrupt operation when the fuel level in
the tank is low, reducing the chance of introducing air into the fuel lines.
Note:
During this test, if the Top Suction Kit
does not function as stated, call Technical
Services for assistance.
Note:
To check low fuel cut-off function, see Thermostat Testing (Section 9.3.1).
Procedure :
1.
Run the pump vacuum check (Section 9.3.4, steps 12
–16) and make sure that you
have proper and tight flare connections. If there is a leak, repair it or call for assistance.
2.
Disconnect the 3/8” copper tube at union above the tank. Disconnect wiring for low fuel
cut-off switch.
3.
Remove the suction copper and foot valve from tank.
4.
Clean the oil from the suction copper and foot valve thoroughly.
5.
With the suction copper vertical (as it mounts in the tank), fill the tube with oil. Place a
clean paper towel under the foot valve.
6.
Let the filled assembly set for 20 minutes. Inspect for oil leaks on the paper towel.
7.
If there is evidence of a leak, and it can be located, repair if possible using thread
sealant. If repair is not possible, call for assistance or order replacement parts.
